     14 
     15 	[configure.ac] More checks for the support of old dtags.
     16 
     17 	There is an attempt to use the old dtags when LD_LIBRARY_PATH is
     18 	defined in order to avoid issues with the testsuite when this path
     19 	contains some compatible version of the MPFR library. However, the
     20 	old dtags do not work everywhere at run time, even when they appear
     21 	to work at link time (via -Wl,--disable-new-dtags).
     22 
     23 	So, let's restrict to *-*-linux-gnu hosts. Unfortunately, this is
     24 	not sufficient for Android/Termux, where config.guess currently
     25 	identifies the host as GNU/Linux (matching *-*-linux-gnu) instead of
     26 	Android, but the old dtags do not work at run time. So, let's also
     27 	exclude Termux explicitly (a test to exclude all Android hosts would
     28 	be better, though).
     29 
     30 	Note: in most cases, LD_LIBRARY_PATH is not set, so that there should
     31 	be no issues in practice.

     45 
     46 	[strtofr.c] Fixed 2 mpfr_strtofr bugs in case of huge negative exponent.
     47 
     48 	This fixes the bugs triggered by bug20230606, mentioned at
     49 	  https://sympa.inria.fr/sympa/arc/mpfr/2023-06/msg00000.html
     50 	  https://sympa.inria.fr/sympa/arc/mpfr/2023-06/msg00001.html
     51 
     52 	These bugs are integer overflows, meaning undefined behavior.
     53 	In practice, the consequences may be incorrect results. But
     54 	for the first bug, it has been seen that a GCC optimization
     55 	makes the bug invisible.
     56 
     57 	Note: There are other issues with the code for huge exponents
     58 	(in strtofr.c and the MPFR_SADD_OVERFLOW macro from mpfr-impl.h).
     59 	See FIXME from commits

     61 	  e06a073c157fe95dd24d16d9fc3eef3781b58795
     62 	in master. But it is not clear whether the problematic cases can
     63 	occur in the context of mpfr_strtofr: my attempts to trigger a
     64 	problematic case failed, so that there is a chance that the code
     65 	is actually correct; but many parameters are involved, including
     66 	those based on the internal structure in limbs, so that it is
     67 	difficult to say for now. A closer analysis needs to be done.
     68 	Even if correct, the code would need to be cleaned up, proved,
     69 	and better documented.
     70 
     71 2023-08-17  Vincent Lefevre  <vincent (a] vinc17.net>
     72 
     73 	[tests/tstrtofr.c] Added testcases for mpfr_strtofr integer overflows.
     74 
     75 	These bugs occur on inputs with a large negative exponents, such as
     76 	"0.1E-99999999999999999999".
     77 
     78 	A first bug was reported by Michael Jones at
     79 	  https://sympa.inria.fr/sympa/arc/mpfr/2023-06/msg00000.html
     80 
     81 	Second bug mentioned at
     82 	  https://sympa.inria.fr/sympa/arc/mpfr/2023-06/msg00001.html

     85 
     86 	[doc/mpfr.texi] Updated the month.
     87 
     88 2023-08-15  Vincent Lefevre  <vincent (a] vinc17.net>
     89 
     90 	Formatted output functions: fixed +/space flags on NaN and Inf.
     91 
     92 	This is about the documentation and behavior of the mpfr_printf,
     93 	etc. functions on MPFR numbers (mpfr_t) only, i.e. with the R
     94 	type specifier.
     95 
     96 	The + and space flags were ignored on NaN and Inf. While this
     97 	was loosely documented as such (without an explicit mention of
     98 	these flags), the GNU MPFR manual also says that the flags have
     99 	the same meaning as for the standard printf function. So this
    100 	was contradictory and regarded as a bug.
    101 
    102 	Behaving like the ISO C standard should give less surprise, and
    103 	this is probably what is expected (better for alignment purpose).
    104 
    105 	This was partly discussed at
    106 	  https://sympa.inria.fr/sympa/arc/mpfr/2023-03/msg00003.html
    107 	(only for NaN and the + flag at that time).
    108 
    109 	* doc/mpfr.texi: corrected the documentation.
    110 	* src/vasprintf.c: fixed (the code is now simpler since the rule
    111 	  is the same in all cases: real and non-real values).
    112 	* tests/tsprintf.c: grouped all the tests of NaN and Inf, and
    113 	  added much more tests (by constructing the format string in
    114 	  nested loops instead of just a few hardcoded cases).
    115 
    116 2023-08-15  Vincent Lefevre  <vincent (a] vinc17.net>
    117 
    118 	[src/vasprintf.c] Coding style.
    119 
    120 2023-08-10  Vincent Lefevre  <vincent (a] vinc17.net>
    121 
    122 	[configure.ac] For libgmp, replaced AC_CHECK_LIB by our own link test.
    123 
    124 	The issue with AC_CHECK_LIB is that it cannot know the prototype of
    125 	mpz_init. Thus it declares the function without a prototype, which
    126 	is obsolescent in ISO C, so that the compiler may complain (e.g.
    127 	with GCC's -Werror=strict-prototypes option, which may be useful to
    128 	detect bugs in MPFR). Moreover, the call is done with an incorrect
    129 	prototype, which could also be an issue on some systems (currently,
    130 	no prototype check is done when linking, but this might change in
    131 	the future).
    132 
    133 	Note also that this new test is more robust, in case GMP changes the
    134 	symbol name in the future (the API does not need to be changed).
    135 
    136 	For the reference:
    137 	  https://sympa.inria.fr/sympa/arc/mpfr/2023-08/msg00003.html
    138 
    139 2023-08-10  Vincent Lefevre  <vincent (a] vinc17.net>
    140 
    141 	[configure.ac] Do the MPFR_CHECK_MP_LIMB_T_VS_* tests without -lgmp.
    142 
    143 	Moved the two tests
    144 
    145 	  MPFR_CHECK_MP_LIMB_T_VS_LONG
    146 	  MPFR_CHECK_MP_LIMB_T_VS_INTMAX
    147 
    148 	before the LIBS="-lgmp $LIBS" as linking with GMP is not needed for
    149 	these tests (only mp_limb_t is used from gmp.h), and it is actually
    150 	better not to link with GMP. Indeed, as said for these tests, which
    151 	use AC_LINK_IFELSE:
    152 
    153 	  AC_LINK_IFELSE is safer than AC_COMPILE_IFELSE, as it will detect
    154 	  undefined function-like macros (which otherwise may be regarded
    155 	  as valid function calls with AC_COMPILE_IFELSE since prototypes
    156 	  are not required by the C standard).
    157 
    158 	So linking with GMP could make a failure disappear in case of a bug
    159 	somewhere, so that the bug could remain undetected.
    160 
    161 2023-08-10  Vincent Lefevre  <vincent (a] vinc17.net>
    162 
    163 	[acinclude.m4] Replaced <gmp.h> by "gmp.h" for #include.
    164 
    165 	The tests from configure.ac all use #include "gmp.h", and for the
    166 	MPFR build and tests, gmp.h is also included with #include "gmp.h"
    167 	(by mpfr-impl.h). For consistency, do the same in acinclude.m4.
    168 
    169 	Note: In practice, there should not be a difference, except if there
    170 	is a gmp.h file somewhere in the MPFR build tree. But this is not
    171 	supported, and this may break the build or the testsuite (whatever
    172 	is used in the configure tests).
    173 
    174 2023-07-19  Vincent Lefevre  <vincent (a] vinc17.net>
    175 
    176 	[src/mpfr-gmp.h] Fix integer overflow when mp_limb_t < int (mini-gmp).
    177 
    178 	When mp_limb_t is shorter than int (which is possible with mini-gmp),
    179 	an integer promotion in udiv_qr_3by2 triggers an integer overflow,
    180 	detected by testing MPFR with
    181 
    182 	  ./configure --with-mini-gmp=/path/to/mini-gmp CC=gcc-13 \
    183 	  CFLAGS="-O2 -fsanitize=undefined -fno-sanitize-recover
    184 	          -DMINI_GMP_LIMB_TYPE=short"
    185 
    186 	(many tests fail).
    187 
    188 	Note that this is not detected by GCC 12 and before, probably due to
    189 	an optimization bug that hides the UBsan error.
    190 
    191 	Moreover, mini-gmp currently has the same bug in gmp_udiv_qr_3by2,
    192 	but also in gmp_udiv_qrnnd_preinv; it needs to be fixed too in order
    193 	to avoid the failures in the MPFR tests.
    194 
    195 2023-07-19  Vincent Lefevre  <vincent (a] vinc17.net>
    196 
    197 	[tests/trint.c] C2x compat: replaced function without a prototype.
    198 
    199 	The second parameter of test_fct was "int (*g)()", i.e. a pointer to
    200 	a function without a prototype, because 2 kinds of prototypes can be
    201 	used:
    202 	  * one with args (mpfr_ptr, mpfr_srcptr);
    203 	  * one with args (mpfr_ptr, mpfr_srcptr, mpfr_rnd_t),
    204 	    but only for mpfr_rint.
    205 	This was not a problem thanks to the test "g == &mpfr_rint", i.e.
    206 	we knew which one to use. However, as the Clang 16 warning message
    207 	says for -Wdeprecated-non-prototype:
    208 	"passing arguments to a function without a prototype is deprecated
    209 	in all versions of C and is not supported in C2x".
    210 
    211 	The best way to fix this is to use the prototype with 2 arguments
    212 	(mpfr_ptr, mpfr_srcptr) for the parameter, as this is the general
    213 	case. All we need to do is to cast &mpfr_rint to this prototype
    214 	(this appears only twice).
    215 
    216 	As these casts trigger the -Wcast-function-type warning when enabled,
    217 	let's explicitly disable this warning for GCC and Clang in versions
    218 	where it has been introduced.
    219 
    220 2023-07-18  Vincent Lefevre  <vincent (a] vinc17.net>
    221 
    222 	[tests/tfpif.c] Removed "fclose (fh);" under "if (fh == NULL)".
    223 
    224 	The fopen() failed, so fclose() is not needed, and this is even UB.
    225 
    226 	Issue reported by Jerry James:
    227 	  https://sympa.inria.fr/sympa/arc/mpfr/2023-07/msg00002.html
    228 	as GNU libc recently added a "nonnull" function attribute:

    231 2023-07-12  Vincent Lefevre  <vincent (a] vinc17.net>
    232 
    233 	[doc/mpfr.texi] Updated the month.
    234 
    235 	[src/inp_str.c] Resolved the FIXME on a deprecated use of ungetc.
    236 
    237 2023-07-12  Vincent Lefevre  <vincent (a] vinc17.net>
    238 
    239 	Fixed mpfr_strtofr bug in parse_string when isspace(0) is true.
    240 
    241 	When isspace(0) is true (allowed by ISO C for non-"C" locales), '\0'
    242 	would be skipped if part of the leading whitespace. But it must be
    243 	regarded as the terminating null character, from the definition of
    244 	a string (before the notion of whitespace is involved). So let's
    245 	stop explicitly on '\0'.
    246 
    247 	Note: in such locales (Mutt's lib.h suggests that some systems are
    248 	affected, but this was in 1998), this is a security vulnerability,
    249 	because characters after the terminating null character are read to
    250 	determine the result.
    251 
    252 2023-07-12  Vincent Lefevre  <vincent (a] vinc17.net>
    253 
    254 	[inp_str.c] mpfr_inp_str: fixed the handling of '\0' in the word.
    255 
    256 	When '\0' is not a whitespace character (which is almost always the
    257 	case in practice), it was not handled correctly. For instance, if the
    258 	word is the sequence { '1', '\0', '2' }, the string "1" was passed to
    259 	mpfr_set_str because '\0' is regarded as a terminating null character,
    260 	and one was getting a valid number while '\0' in a word is necessarily
    261 	invalid. This is fixed by putting '*' at the beginning of the string,
    262 	which is thus necessarily invalid.
    263 
    264 	This fixes the failure after c9523bc6fb11c8eefc75524e947e5eb81e682675
    265 	(4642e68fb3cd6793a51537cfc86a7cb3ef1c0a4c in the 4.2 branch).
    266 
    267 2023-07-12  Vincent Lefevre  <vincent (a] vinc17.net>
    268 
    269 	[tests/inp_str.dat] Make the word that contains '\0' look like a number.
    270 
    271 	Changed ".\0." to "1\01" (\0 being the null character) in order to
    272 	trigger a failure with the current mpfr_inp_str code. The issue is
    273 	that '\0' makes the word look like the string "1", the '\0' being
    274 	regarded as a terminating null character. This is incorrect as '\0'
    275 	is part of the full word.
    276 
    277 2023-07-12  Vincent Lefevre  <vincent (a] vinc17.net>
    278 
    279 	[manual] Clarified the return value of mpfr_inp_str.
    280 
    281 2023-07-12  Vincent Lefevre  <vincent (a] vinc17.net>
    282 
    283 	Added a '\0' test for mpfr_inp_str.
    284 
    285 	After ensuring that isspace(0) is false, make sure that '\0' is
    286 	handled as a normal non-whitespace character.
    287 
    288 	Also note that inp_str.dat does not end with a newline character
    289 	on purpose, in order to check that a number at the end of the file
    290 	(with no whitespace after it) is handled correctly.
    291 
    292 2023-07-12  Vincent Lefevre  <vincent (a] vinc17.net>
    293 
    294 	Improved the mpfr_inp_str tests.

    296 2023-07-12  Vincent Lefevre  <vincent (a] vinc17.net>
    297 
    298 	[tests/inp_str.dat] Added the other standard whitespace characters.
    299 
    300 	These are:
    301 	  * space (' ');
    302 	  * ^I (horizontal tab '\t');
    303 	  * ^J (newline '\n', already there);
    304 	  * ^K (vertical tab '\v');
    305 	  * ^L (form feed '\f');
    306 	  * ^M (carriage return '\r').
    307 
    308 2023-07-12  Vincent Lefevre  <vincent (a] vinc17.net>
    309 
    310 	[MPFR manual] Corrected description of mpfr_inp_str.
    311 
    312 	The description seemed to assume that there was leading and trailing
    313 	whitespace (due to "between whitespace"). Also clarify what whitespace
    314 	is: defined by isspace(), which depends on the current locale.
    315

    322 
    323 	This bug appeared in GCC 12, but it is more serious in GCC 13

    398 2023-05-17  Vincent Lefevre  <vincent (a] vinc17.net>
    399 
    400 	[tcompound.c] Added bug_20230517 (integer overflow in compound.c).
    401 
    402 	and updated comment for the 4.2 branch.
    403 
    404 2023-05-16  Vincent Lefevre  <vincent (a] vinc17.net>
    405 
    406 	[src/vasprintf.c] Fixed bug triggered by the large_prec_for_g test.
    407 
    408 	Bug fixes in partition_number():
    409 	* Fixed the type of the variable `threshold`: as this variable may
    410 	  contain spec.prec, it needs to be of type mpfr_intmax_t.
    411 	  This was the cause of the "MPFR assertion failed: threshold >= 1"
    412 	  (or the incorrect size when assertions are not checked) with the
    413 	  large_prec_for_g test.
    414 	* Also make sure that the 4th argument given to mpfr_get_str fits
    415 	  in a size_t (if it doesn't, return with a failure, as done when
    416 	  reaching other environmental limits).
    417 	  In practice, this could be an issue only with a 32-bit size_t and
    418 	  mpfr_exp_t on more than 32 bits.
    419 
    420 2023-05-16  Vincent Lefevre  <vincent (a] vinc17.net>
    421 
    422 	[tests/tsprintf.c] Added large_prec_for_g, which makes MPFR crash.
    423 
    424 	On a 64-bit Linux machine, the case %.2147483648Rg yields an incorrect
    425 	size computation and MPFR wants to allocate 18446744071562070545 bytes.
    426 	This case should either succeed or fail as reaching an environmental
    427 	limit like with glibc (note that the precision does not fit in an int).
    428 
    429 2023-05-16  Vincent Lefevre  <vincent (a] vinc17.net>
    430 
    431 	[manual] Detailed mpfr_compound_si description (special cases).
    432 
    433 	The MPFR manual should be self-contained. So, let's describe
    434 	the special cases of mpfr_compound_si that do not follow the
    435 	usual rules (or are ambiguous), instead of just referring to
    436 	the IEEE 754 standard.
    437 
    438 2023-05-16  Vincent Lefevre  <vincent (a] vinc17.net>
    439 
    440 	[compound.c] Fixes concerning the overflow and underflow detection.
    441 
    442 	Note: It is not clear whether overflow and underflow detection is
    443 	now correct. There may still be potential issues, but currently,
    444 	after these fixes, no tests yield any failure (however, we do not
    445 	test some of the most problematic cases yet; this should be a
    446 	future improvement of ofuf_thresholds in the master branch).
    447 
    448 	Note: compound.c now corresponds to the version in master.
    449 
    450 2023-05-16  Vincent Lefevre  <vincent (a] vinc17.net>
    451 
    452 	[tcompound.c] Added various tests.
    453 
    454 	* Added bug_20230206, based on a bug report by Patrick Plissier.
    455 	* Implemented the inverse function x^(1/n) - 1 of the compound function
    456 	  on non-special cases: useful to build and check hard-to-round cases
    457 	  and test the behavior close to the overflow and underflow thresholds.
    458 	* Check hard-to-round cases for n = 2, 3, 4, 5, 17, 120 (like in tpow.c)
    459 	  and also call the generic tests for these values.
    460 	* Added bug_20230211 (buggy overflow detection for 32 bits after the
    461 	  fix of bug_20230206 in master).
    462 
    463 	and updated two comments for the 4.2 branch.
    464 
    465 	Note: Every change has been cherry picked from master, except a
    466 	TODO comment and the ofuf_thresholds() calls (feature not yet in
    467 	the 4.2 branch). And bug_20230206 has not been fixed yet in the
    468 	4.2 branch.
    469 
    470 2023-05-15  Vincent Lefevre  <vincent (a] vinc17.net>
    471 
    472 	[tests.c] In bad_cases(), handle the inex_inv case better.
    473 
    474 	The "f exact while f^(-1) inexact" case is actually almost the same
    475 	as the "inverse doesn't match" case. So, handle it in the same way,
    476 	avoiding a fatal error (which would be bad for the non-developers):
    477 	a few occurrences of this case should be regarded as normal, and if
    478 	this occurs too often, this will be detected like the other case
    479 	when the MPFR_CHECK_BADCASES environment variable is set.
    480 
    481 	This is useful for future bad_cases() calls.
    482 
    483 2023-05-12  Vincent Lefevre  <vincent (a] vinc17.net>
    484 
    485 	[src/pow.c] Fixed a corner case in mpfr_pow_general (bug20230427).
    486 
    487 	This fixes the bug triggered by bug20230427 added in commit 85bc7331c:
    488 	  bug20230427 triggers another bug in mpfr_pow_general, which
    489 	  occurs in destination precision 1 in the particular case of
    490 	  rounding to nearest, z * 2^k = 2^(emin - 2) and real result
    491 	  larger than this value.
    492 
    493 	This corresponds to a particular hunk of a diff from master,
    494 	or with a cherry-pick from commits

    504 2023-05-12  Vincent Lefevre  <vincent (a] vinc17.net>
    505 
    506 	[src/pow.c] Fixed error bound in mpfr_pow_general (bug20230213).
    507 
    508 	This fixes the bug triggered by bug20230213 added in commit 85bc7331c:
    509 	  bug20230213 triggers a bug in mpfr_pow_general, where the
    510 	  computation of the error term is incorrect when there has
    511 	  been an intermediate underflow or overflow (k_non_zero is
    512 	  true); the error analysis is correct, but the associated
    513 	  code is not (due to the change of the value of a variable).
    514 
    515 2023-05-12  Vincent Lefevre  <vincent (a] vinc17.net>
    516 
    517 	[tests/texp10.c] Added bug20230213 and bug20230427 tests.
    518 
    519 	* bug20230213 triggers a bug in mpfr_pow_general, where the
    520 	  computation of the error term is incorrect when there has
    521 	  been an intermediate underflow or overflow (k_non_zero is
    522 	  true); the error analysis is correct, but the associated
    523 	  code is not (due to the change of the value of a variable).
    524 	* bug20230427 triggers another bug in mpfr_pow_general, which
    525 	  occurs in destination precision 1 in the particular case of
    526 	  rounding to nearest, z * 2^k = 2^(emin - 2) and real result
    527 	  larger than this value.
    528 
    529 	Note: The code has been copied from master (and because of changes
    530 	of other parts of the code by commits in master, cherry-picking
    531 	was impossible or much more complex). These bugs have been fixed
    532 	in master, but these fixes will be provided in the 4.2 branch by
    533 	separate commits in order to facilitate testing (e.g., to check
    534 	that one gets failures without these fixes).
    535 
    536 	Both bugs were found by the current ofuf_thresholds tests in master
    537 	(but there are currently issues with these tests).
    538 
    539 2023-05-12  Vincent Lefevre  <vincent (a] vinc17.net>
    540 
    541 	Added bad_cases tests for mpfr_exp2, mpfr_exp10, mpfr_log2, mpfr_log10.
    542 
    543 	[tests/tui_pow.c] Added generic tests.
    544 
    545 	Added /treldiff to tests/.gitignore
    546 
    547 2023-05-12  Vincent Lefevre  <vincent (a] vinc17.net>
    548 
    549 	[tests/tui_pow.c] Some small corrections.
    550 
    551 	* Improved organization and style.
    552 	* Replaced output to stderr by output to stdout (as usual).
    553 	* Added missing "\n" at the end of 2 printf strings.
    554 
    555 2023-05-05  Vincent Lefevre  <vincent (a] vinc17.net>
    556 
    557 	[tests/tset_float128.c] check_special(): output values in error messages.
    558 
    559 2023-05-04  Vincent Lefevre  <vincent (a] vinc17.net>
    560 
    561 	[doc/mpfr.texi] Updated the month.
    562 
    563 	[src/Makefile.am] Updated -version-info to 8:1:2 for MPFR 4.2.1.
    564 
    565 2023-05-04  Vincent Lefevre  <vincent (a] vinc17.net>
    566 
    567 	Updated version to 4.2.1-dev (with tools/update-version).
    568 
    569 	This should have been done just after 4.2.0 was published,
    570 	i.e. just after the 4.2.0 tag, but I forgot.
    571 
    572 2023-05-04  Vincent Lefevre  <vincent (a] vinc17.net>
    573 
    574 	Added treldiff.c test, assuming that mpfr_reldiff behaves as documented.
    575 
    576 	Basically, mpfr_reldiff is tested with all special numbers and some
    577 	regular ones, with various precisions and all the rounding modes
    578 	(including MPFR_RNDF since in practice, the implementation cannot
    579 	exploit it to give failures). The result is just compared with the
    580 	basic algorithm (as documented), which does not use any optimization
    581 	(i.e. it does not treat special numbers in a particular way): the
    582 	formula is just computed using the precision of the destination and
    583 	the provided rounding mode for all operations (thus, in general,
    584 	this mpfr_reldiff function is not correctly rounded).
    585 
    586 	This test would detect the bugs on special values that have been fixed
    587 	in 81e4d4427eed0404292ac69c17f986a6cb640562.
    588 
    589 2023-05-04  Vincent Lefevre  <vincent (a] vinc17.net>
    590 
    591 	[src/reldiff.c] Fixed mpfr_reldiff on special values.
    592 
    593 	The mpfr_reldiff function, which computes |b-c|/b, was buggy on
    594 	special values, e.g. on the following (b,c) values:
    595 	  * (+Inf,+Inf) gave 0 instead of NaN (like NaN/Inf).
    596 	  * (+0,+0) gave 1 instead of NaN (like 0/0).
    597 	  * (+0,1) gave 1 instead of Inf (like 1/0).
    598 
    599 	The sign of 0 for (+Inf,+Inf) or (-Inf,-Inf) was not set, i.e. it
    600 	was just the sign of the destination before the call. This made
    601 	the "reuse" test fail after its update to check the sign of zero
    602 	(commit e6d47b8f5ab666e658e05fe282e3490a06c0278e), as the results
    603 	were not consistent.
    604 
    605 	For b = 0, there was a comment "reldiff = abs(c)/c = sign(c)", which
    606 	mixed up b and c (one should divide by b, not by c), and this could
    607 	explain some bugs.
    608 
    609 	Note that this comment (and associated code), if corrected, seemed to
    610 	imply that for c = 0 and b finite (and non-zero?), the intent was to
    611 	return sign(b). However, this does not follow the documentation, which
    612 	says that the formula is just computed using the precision of the
    613 	destination and the provided rounding mode for all operations. So the
    614 	final result may be affected by intermediate roundings, while sign(b)
    615 	assumes that the function is correctly rounded, which is not the case
    616 	for this function (just there for compatibility with MPF). Deviating
    617 	from the documentation in some cases could break some properties (like
    618 	monotonicity?).
    619 
    620 	These bugs were not found because mpfr_reldiff is not tested at all,
    621 	except by "reuse", which just checks some consistency when a variable
    622 	is reused for the destination.
    623 
    624 2023-05-04  Vincent Lefevre  <vincent (a] vinc17.net>
    625 
    626 	[tests/reuse.c] Check the sign of zero; other improvements.
    627 
    628 	* Replaced the static mpfr_compare by "! SAME_VAL" to do a complete
    629 	  comparison of MPFR numbers. In particular, this checks the sign of
    630 	  zero, revealing a bug in mpfr_reldiff (failure 0 vs -0).
    631 	* More consistent output of errors (use of mpfr_dump for ref and res
    632 	  in all cases).
    633 	* Code style.
    634 
    635 2023-04-20  Vincent Lefevre  <vincent (a] vinc17.net>
    636 
    637 	[tests/tsprintf.c] Updated comment for snprintf_size.
    638 
    639 	Like commit 524c7bf4ff4f0dc1c83bc9a36d621a4a9607ee3b in master,
    640 	but without the "Code reworked..." line, as this isn't done in
    641 	the 4.2 branch.
    642 
    643 2023-04-17  Vincent Lefevre  <vincent (a] vinc17.net>
    644 
    645 	[tests/tsprintf.c] Update about the glibc 2.37 bug.
    646 
    647 	This updates commit 78ff7526dea103f73acc98d9a9ffa7429050c0dd.
    648 
    649 2023-04-17  Vincent Lefevre  <vincent (a] vinc17.net>
    650 
    651 	Fixed possible stack overflow in mpfr_rec_sqrt + non-regression test.
    652 
    653 	* src/rec_sqrt.c: use a standard Ziv loop.
    654 	* tests/trec_sqrt.c: added a non-regression test with bad_cases().
    655 
    656 	Details:
    657 
    658 	The issue is due to many allocations in the stack (with alloca(),
    659 	via MPFR_TMP_LIMBS_ALLOC) on cases that are very hard to round (from
    660 	an analysis on a testcase given by Fredrik Johansson, not included
    661 	here) with a not too large destination precision: many iterations
    662 	are needed due to a specific Ziv loop where the working precision
    663 	is increased additively, and it is not possible to free the data
    664 	allocated in the previous iterations.
    665 
    666 	The fix is to use a standard Ziv loop, as it increases the working
    667 	precision multiplicatively instead of additively, so that it needs
    668 	much fewer iterations in such cases. This should also make the code
    669 	much faster in such cases.
    670 
    671 	This issue was not detected by bad_cases() in tests/trec_sqrt.c
    672 	because to be able to reproduce it, one needs a much larger precision
    673 	than the ones tested with the chosen parameters.
    674 
    675 	A new bad_cases() instance, with a large enough precision for the
    676 	input (py = 9999, psup = 120000, giving px = py + psup = 129999),
    677 	is added here in order to be able to reproduce the failure.
    678 
    679 	The testcase given by Fredrik Johansson is not included here because
    680 	it uses a very large string for the input (the point of bad_cases()
    681 	is to generate such an input automatically).
    682 
    683 2023-04-15  Vincent Lefevre  <vincent (a] vinc17.net>
    684 
    685 	[src] Since mpfr_prec_t is signed, changed %Pu to %Pd.
    686 
    687 	Note: Even the mpfr_prec_t is not supposed to contain negative values
    688 	(at least in these cases), this may still be useful in case of bugs.
    689 
    690 2023-04-14  Vincent Lefevre  <vincent (a] vinc17.net>
    691 
    692 	[doc/mpfr.texi] Updated the month.
    693 
    694 2023-04-14  Vincent Lefevre  <vincent (a] vinc17.net>
    695 
    696 	[manual] Improved example on how to print a mpfr_prec_t value.
    697 
    698 	mpfr_prec_t is signed, so that it is better to use %Pd than %Pu.
    699 
    700 2023-04-12  Vincent Lefevre  <vincent (a] vinc17.net>
    701 
    702 	[src/mpfr-thread.h] Output a message in case of lock/unlock failure.
    703 
    704 	The message is output just before abort(), so that one can know
    705 	the cause of the abort().
    706 
    707 	Tested with --enable-shared-cache CC=i686-w64-mingw32-gcc-posix
    708 	(which has the effect to enable POSIX threads inside MPFR via
    709 	AX_PTHREAD, with MinGW), where
    710 
    711 	MPFR_LOCK_DECL(mpfr_lock_memory)
    712 	int main (void)
    713 	{
    714 	  MPFR_LOCK_WRITE(mpfr_lock_memory);
    715 	  return 0;
    716 	}
    717 
    718 	fails with the "MPFR lock failure" message and exit status 3 due to
    719 	the abort(). Note that there is no failure with GNU/Linux.
    720 
    721 2023-03-22  Vincent Lefevre  <vincent (a] vinc17.net>
    722 
    723 	[doc/mpfr.texi] Updated the month.
    724 
    725 	[manual] Detailed mpfr_set_str a bit more.
    726 
    727 2023-02-28  Vincent Lefevre  <vincent (a] vinc17.net>
    728 
    729 	[tests] Added/improved tests for the log, log2 and log10 functions.
    730 
    731 	* Added log(1) test.
    732 	* For the special tests of these functions: test in all rounding modes
    733 	  and use MPFR_IS_ZERO(x) rather than mpfr_cmp_ui(x,0) to exclude NaN.
    734 
    735 2023-02-21  Vincent Lefevre  <vincent (a] vinc17.net>
    736 
    737 	Fixed mpfr_ui_pow_ui infinite loop in case of overflow, with testcases.
    738 
    739 	* src/ui_pow_ui.c:
    740 	    - Cleanup. In particular, renamed a variable as this was confusing:
    741 	      one usually uses y = f(x), but here it was x = f(y,n). Let's use
    742 	      x = f(k,n) since here, both arguments are integers.
    743 	    - Added mpfr_ui_pow_ui logging.
    744 	    - Handle the +Inf case in the Ziv iteration.
    745 	      This is done by calling mpfr_pow_z (this should be a bit more
    746 	      efficient than calling mpfr_pow_ui, which would eventually call
    747 	      mpfr_pow_z to handle the overflow).
    748 	      Note that mpfr_pow_z avoids spurious overflows by internally
    749 	      rounding toward 1 (for positive results). This might be an
    750 	      alternative solution here to avoid calling mpfr_pow_z.
    751 	* tests/tlog10.c: added bug20230213 test: infinite loop in mpfr_log10,
    752 	  which was occurring before the above bug fix.
    753 	* tests/tui_pow.c: added testcase for this mpfr_ui_pow_ui bug.
    754 
    755 2023-02-14  Vincent Lefevre  <vincent (a] vinc17.net>
    756 
    757 	For -dev versions, enable timeout support by default (when possible).
    758 
    759 	* configure.ac:
    760 	    - added dev_version variable, set to 1 for -dev versions;
    761 	    - updated --enable-tests-timeout handling;
    762 	    - use $dev_version for a test that already considers -dev versions.
    763 	* acinclude.m4:
    764 	    - handle absent --enable-tests-timeout option and case "yes".
    765 
    766 2023-02-03  Vincent Lefevre  <vincent (a] vinc17.net>
    767 
    768 	[tests/tsprintf.c] Added a comment about a failure with glibc 2.37.
    769 
    770 	Klaus Dittrich reported in the MPFR mailing-list that the modified
    771 	test from commit 4f03d40b5a5ceeb3126dc51c3511bdceef3bab19 was still
    772 	failing with the glibc git. But this time, this is entirely a bug
    773 	in glibc, present in glibc 2.37:
    774 
    775 	  https://sourceware.org/bugzilla/show_bug.cgi?id=30068
    776 
    777 	with even a possible buffer overflow in sprintf (as I guessed

    785 	[tests/{tfprintf.c,tprintf.c}] Fix when decimal_point > 1 byte.
    786 
    787 	These tests were failing in locales where localeconv()->decimal_point
    788 	takes several bytes, such as in the ps_AF locale under Linux, where
    789 	decimal_point is U+066B ARABIC DECIMAL SEPARATOR, which takes 2 bytes
    790 	(d9 ab, as encoded in UTF-8).
    791 
    792 	Note: A multibyte decimal-point is currently honored only with
    793 	native C types (via the C library), so that the length of the
    794 	decimal-point had to be taken into account only for a small number
    795 	of tests. Once a multibyte decimal-point is supported for the MPFR
    796 	numbers ("R" type specifier), the expected lengths in many tests
    797 	will have to be updated. See the code about MPFR_DECIMAL_POINT in
    798 	"src/mpfr-impl.h".

    807 
    808 	* Added info for the fr_FR.UTF-8 and ps_AF locales.
    809 	* Removed the sentence about the C standard (since multibyte characters
    810 	  are used for decimal_point and thousands_sep in practice, the term

    824 
    825 	  https://sourceware.org/bugzilla/show_bug.cgi?id=23432
    826 
    827 	The GNU C Library has apparently been partially fixed in its Git
    828 	repository for the future 2.37, since a tsprintf failure has been
    829 	reported (this is a bug in this test, not in the MPFR library):
    830 
    831 	  https://sympa.inria.fr/sympa/arc/mpfr/2023-01/msg00001.html
    832 
    833 	So, modified the test to avoid the particular case of leading zeros
    834 	due to the precision field larger than the number of digits. This
    835 	case has already been tested without the thousands separator (where
    836 	there are no issues with the C libraries), so that we do not miss
    837 	much testing. Added a comment explaining the issue and a possible

    924 
    925 	The reason is that on some platforms, GMP chooses a non-default mode
    926 	(a.k.a. ABI). MPFR has some workaround thanks to GMP_CC and GMP_CFLAGS
    927 	provided by GMP, but this may not be sufficient, e.g. on power-aix. In
    928 	such a case, the user needs to either force GMP to use the default mode
    929 	or provide an AR variable for MPFR's configure; see INSTALL file.

   1023 	[tests/mpfr-test.h] Improved the change done a few hours earlier.
   1024 
   1025 	The code introduced by commit 558a246e612fa230623fb0dfa0570b1c626a103c
   1026 	was changing the conditions under which IGNORE_CPP_COMPAT is defined
   1027 	(to ignore -Wc++-compat with a GCC pragma). Let's simplify it by using
   1028 	our __MPFR_GNUC() macro. The only possible change of behavior is that
   1029 	this excludes Intel's compiler (which is probably better as testing
   1030 	the GCC version on Intel's compiler doesn't make sense).
   1031 
   1032 	Note concerning the behavior of Intel icx 2021.3.0 under Linux: Before
   1033 	the above commit, it was not excluded; but after this above commit, it
   1034 	was excluded as it identifies itself as GCC 4.2.1 (like Clang). With
   1035 	this new change, it is still excluded. Anyway, it ignores -Wc++-compat
   1036 	and doesn't complain on the GCC pragmas, so the above choice currently
   1037 	doesn't matter.
   1038 
   1039 2022-12-11  Vincent Lefevre  <vincent (a] vinc17.net>

   1041 	Avoid a testsuite build failure with GCC older than 4.6.
   1042 
   1043 	In tests/mpfr-test.h, we must not define IGNORE_CPP_COMPAT for
   1044 	GCC < 4.6 as it does not allow "#pragma GCC diagnostic" inside
   1045 	functions. Moreover, let's define it for all Clang versions,
   1046 	including MS Windows (where __GNUC__ is not defined).

   1060 
   1061 	In short, since commit a6e9d69047a358bfd1aaa1418d9999b8abe0bb62,
   1062 	version-ext.sh should no longer be needed in EXTRA_DIST because

   1066 2022-12-06  Vincent Lefevre  <vincent (a] vinc17.net>
   1067 
   1068 	Fixed version-ext.sh usage, avoiding "make check" failure and incorrect
   1069 	version information.
   1070 
   1071 	The use of version-ext.sh could be incorrect when the MPFR source tree
   1072 	was in a Git working tree:
   1073 	  * "make check" could fail in some cases, see the bug report by

   1075 	       https://sympa.inria.fr/sympa/arc/mpfr/2022-12/msg00000.html
   1076 	  * Version information output by "make check" could be incorrect.
   1077 
   1078 	Changes:
   1079 	* tests/Makefile.am: For output_info, we now also check whether
   1080 	  $(top_srcdir)/.git is readable in order to avoid escaping the
   1081 	  MPFR source tree. In particular, if one extracts an MPFR tarball
   1082 	  within a Git working tree (e.g. after "make dist"), then running
   1083 	  "make check" in this extracted source tree will work as expected,
   1084 	  giving correct version information.
   1085 	* tests/Makefile.am, version-ext.sh: Updated comments. In particular,
   1086 	  moved a comment from tests/Makefile.am to version-ext.sh; this should
   1087 	  have been done in commit 0d3abf10458ca4fdd26daa77a02f7f1f4e361deb,

   1100

   1132

   1139 	Get rid of the _mulx_u64 intrinsic.
   1140 
   1141 	It was found that this intrinsic has issues with ICC, Cygwin, and more
   1142 	generally, the Microsoft toolchain; even MPFR's strong detection at
   1143 	configure time (an AC_RUN_IFELSE test) was not sufficient. Moreover,
   1144 	_mulx_u64 is useless as umul_ppmm from mpfr-longlong.h does the same
   1145 	thing from the spec point of view (and thus was used as the fallback).
   1146 	So, if there is a reliable way to use the mulx instruction whenever
   1147 	possible (including via compiler optimization and the use of __int128
   1148 	when available, as done by GCC's _mulx_u64 implementation), this
   1149 	should be done in the umul_ppmm definition. Alternatively, we could
   1150 	redefine umul_ppmm for the use of __int128 when possible.

   1159 	* src: corrected the umul_hi(h, x, y) macro (the only code that was

   1191 
   1192 	Fix mpfr_custom_get_kind() macro bug.
   1193 
   1194 	* src/mpfr.h: in the mpfr_custom_get_kind() macro, changed mpfr_ptr to
   1195 	  mpfr_srcptr for _x to agree with the function prototype, in order to
   1196 	  avoid a compilation failure of user code in some cases. This bug was
   1197 	  introduced by commit 9f94e0311ed53d0c64d4fbca249d19cc4888027e, which
   1198 	  introduced the temporary variable _x to avoid an incorrect number of
   1199 	  evaluations of the x argument.
   1200 	* tests/tstckintc.c: improved the tests to detect this bug.
   1201 
   1202 	This should fix mpfr bug #1.

   1217 
   1218 	A page break was introduced for "@need 800" while there was the
   1219 	space for 12 lines of text + 3 paragraph skips, as seen after the
   1220 	change. That's much more than the 8/10 in needed by "@need 800".
   1221 	So the page break was incorrect!

   1247 	Changed non(zero|positive|negative) to non-zero, etc. for consistency
   1248 	(target files: src & tests directory, doc/README.dev, doc/mpfr.texi).
   1249 	Did it this way because the former was in minority (21 vs 165) and

   1255 
   1256 	Actually a bit more than that, since this affected the textual part
   1257 	of the PDF file (used for searching and copy-paste): the underscore

   1273 	and 7eda345244f503359d14cd5bae1ed42865d39ee8 was incorrect as there
   1274 	are 2 identical replacements to do in "doc/mpfr.texi", not just one.
   1275 	The previous code changed lines separately. But for the check of
   1276 	failing replacements, a global change on the full file is needed;
   1277 	thus the 2 identical replacements were expected to be done at the
   1278 	same time, so that the "g" modifier is needed on the regexp.

   1315 	SVN r13153), and this issue remained unnoticed until now,
   1316 	in particular due to the absence of checking for failing
   1317 	replacements.
   1318 
   1319 	The penultimate non-patchlevel release was done on 2017-12-25, i.e.
   1320 	before this change, and no patchlevel releases have been done yet

   1467 	which was unexpected. This commit removes the use of @math for the
   1468 	Info and HTML output (for Info, this does not change anything, and
   1469 	for HTML, this removes the incorrect emphasis). It also updates the

   1595 
   1596 	The "ChangeLog: FORCE" rule in Makefile.am was incompatible with

   1786 
   1787 	With some 32-bit mingw-w64 implementations, the GMP and libc
   1788 	formatted output functions produce different outputs for %a (this

   1791 	2022-05-19, the comparison is done between the MPFR result, which
   1792 	is based on GMP, and the libc result; hence a failure.
   1793 
   1794 	So, changed the 4 concerned tests of tests/tsprintf.c to compare

   1855 	For the code used when USE_CLOCK_MONOTONIC is defined ("make rt"):
   1856 	If both time_t (type of tv_sec) and long are 32-bit types, there was
   1857 	an overflow in the timp_rdtsc() macro, due to the multiplication of
   1858 	the tv_sec (coming from CLOCK_MONOTONIC, thus typically larger than 5)
   1859 	by the value 1000000000 ( 2^32 / 4.3) of type unsigned long, because
   1860 	this multiplication would be done on 32 bits. Changed the type of the

   1906 
   1907 	[manual] Clarify the description of the formatted output functions.
   1908 
   1909 	Emphasize the fact that the conv specifier F is not supported, except
   1910 	for the type specifier R (for mpfr_t arguments).

   1913 
   1914 	[src/vasprintf.c] Consistency with the non-support of %F by GMP.
   1915 
   1916 	The F conversion specifier as defined by the C standard is not
   1917 	supported by the GMP formatted output functions because it is
   1918 	already used as the type specifier for mpf_t (which comes before
   1919 	the conversion specifier). Let's take this fact into account.
   1920 
   1921 	Note: this conversion specifier is still allowed with MPFR numbers
   1922 	(e.g., "%RF") to avoid breaking the compatibility (it has never
   1923 	been an issue).
   1924 
   1925 2022-05-19  Vincent Lefevre  <vincent (a] vinc17.net>
   1926 
   1927 	[tests/tsprintf.c] native_types: added tests to differentiate %G from %g.
   1928 
   1929 	The tested value -1.25 had the same output -1.25 with %g and %G.
   1930 	Added 7.62939453125e-6 (= 2^(-17)), whose output by %g and %G has
   1931 	an exponent introduced by 'e' and 'E' respectively.
   1932 
   1933 2022-05-19  Vincent Lefevre  <vincent (a] vinc17.net>
   1934 
   1935 	[tests/tsprintf.c] native_types: added tests for %a, %A, %la, %lA
   1936 
   1937 2022-05-19  Vincent Lefevre  <vincent (a] vinc17.net>
   1938 
   1939 	[tests/tsprintf.c] Added/fixed native_types tests.
   1940 
   1941 	* Added tests of %E and %G.
   1942 	* Removed the test of %lF, which is not supported by GMP (and yields
   1943 	  a heap buffer overflow, detected by AddressSanitizer): even though
   1944 	  there would be no ambiguity in this particular case, it is not
   1945 	  supported because the standard F conversion specifier isn't due to
   1946 	  the use of the F type specifier for mpf_t.
   1947 
   1948 2022-05-19  Vincent Lefevre  <vincent (a] vinc17.net>
   1949 
   1950 	[tests/tsprintf.c] Correction for %la, %lA, %le, %lE, %lf, %lF, %lg, %lG
   1951 
   1952 	Reverted commit 2b60707d22717e0f582be5de680d7fa7004e2512 and added
   1953 	tests for the missing %lE, %lF, %lG in native_types, protected by
   1954 	a #if (see commit ecd3279f3dfd281fc8e51aac7509b76b27497a6c) as they
   1955 	may need an ISO C99 compiler.
   1956 
   1957 	Note: The test of %la and %lA was incorrect because the first digit
   1958 	is unspecified (and really depends on the C library). A test could
   1959 	be added in the future, perhaps also with a configure test, because
   1960 	the compiler may support ISO C99 but not the C library (there was
   1961 	an issue like that at least with old versions of Solaris).
   1962 
   1963 2022-05-19  Vincent Lefevre  <vincent (a] vinc17.net>
   1964 
   1965 	[tests/tsprintf.c] native_types: test %le, %lf, %lg only with C99+
   1966 
   1967 	 since the l length modifier for the FP types (a, A, e, E, f, F, g, G
   1968 	conversion specifiers) has been added in ISO C99.
   1969 
   1970 2022-05-19  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   1971 
   1972 	[tests/tsprintf.c] added tests for %la, %lA, %le, %lE, %lf, %lF, %lg, %lG
   1973 
   1974 2022-05-19  Vincent Lefevre  <vincent (a] vinc17.net>
   1975 
   1976 	[src/vasprintf.c] Bug fix for the l length modifier with FP type.
   1977 
   1978 	The l length modifier is now supported with the a, A, e, E, f, F, g, G
   1979 	conversion specifiers, as required by the ISO C standard on printf and
   1980 	other formatted output functions. As specified, it is just ignored.
   1981 
   1982 	For that, to improve code maintainability, the CASE_LONG_ARG() macro
   1983 	was simplified:
   1984 	  * The c and s conversion specifiers are always supported by this
   1985 	    macro (this is a potential fix for implementations with incomplete
   1986 	    wide-character handling, without any guarantee to work).
   1987 	  * A MPFR_RET_NEVER_GO_HERE() for unsupported conversion specifiers
   1988 	    has been added (if specinfo_is_valid() is consistent with this
   1989 	    macro, one should effectively never reach this case).
   1990 
   1991 2022-05-19  Vincent Lefevre  <vincent (a] vinc17.net>
   1992 
   1993 	[src/vasprintf.c] Made case ordering consistent (no change of behavior).
   1994 
   1995 	The "case" ordering in specinfo_is_valid() and in CONSUME_VA_ARG() for
   1996 	integer specifiers and for floating-point specifiers was not the same.
   1997 	Improved code readability by using the same order across the code
   1998 	(also OK with CASE_LONG_ARG()).
   1999 
   2000 2022-05-19  Vincent Lefevre  <vincent (a] vinc17.net>
   2001 
   2002 	[tests/tsprintf.c] native_types: test %le, %lf, %lg.
   2003 
   2004 	These tests are currently failing. Bug reported by Paul Zimmermann
   2005 	for %la (but %a and %la are not currently tested, because of their
   2006 	possible lack of support in the C library).
   2007 
   2008 2022-05-19  Vincent Lefevre  <vincent (a] vinc17.net>
   2009 
   2010 	[tests/tsprintf.c] native_types: same tests for i as for d.
   2011 
   2012 	[tests/tnrandom.c] With mini-gmp, disable the tests that check the values.
   2013 
   2014 	[acinclude.m4] Added a comment about the unreliable NAN != NAN check.
   2015 
   2016 2022-05-19  Vincent Lefevre  <vincent (a] vinc17.net>
   2017 
   2018 	[tests/cmp_str.c] In mpfr_cmp_str, check that s is a valid number.
   2019 
   2020 	In the tests, the string provided to mpfr_cmp_str is normally a
   2021 	valid number (the common use is to check that a result is equal to
   2022 	some hardcoded value given by a string). A string s that does not
   2023 	represent a valid number probably has a typo, and the consequence
   2024 	was that in such a case, any non-NaN result was regarded as correct.
   2025 
   2026 2022-05-19  Vincent Lefevre  <vincent (a] vinc17.net>
   2027 
   2028 	[tests/tsubnormal.c] Removed invalid testcase bug20220518.
   2029 
   2030 	The testcase bug20220518 added in
   2031 	  commit 7640a832fbf0b7f9057889e076cf7f42fe4f8e58
   2032 	was invalid as the mpfr_subnormalize input was not in the current
   2033 	exponent range (it had exponent -1074 while emin = -1073).
   2034 
   2035 	As usual, inputs outside the current exponent range are not supported
   2036 	(the mpfr_subnormalize description in the manual is explicit:
   2037 	"The subnormal exponent range is from emin to emin+PREC(X)-1.").
   2038 	Supporting values outside the current exponent range is not needed
   2039 	in practice (see examples in the manual).
   2040 
   2041 2022-05-19  Vincent Lefevre  <vincent (a] vinc17.net>
   2042 
   2043 	[tests/tsubnormal.c] Code style in coverage().
   2044 
   2045 	[tests/tsubnormal.c] Added missing cleanup at the end of bug20220518.
   2046 
   2047 	[tests/tsubnormal.c] Simplified bug20220518.
   2048

   2052 
   2053 	[tests/tsubnormal.c] added test case that exhibits a bug in mpfr_subnormalize
   2054 	[src/subnormal.c] fixed typo
   2055 
   2056 2022-05-18  Vincent Lefevre  <vincent (a] vinc17.net>
   2057 
   2058 	[tests/tnrandom.c] Check some mpfr_nrandom values to detect changes.
   2059 
   2060 	The values should be the same on different machines and with
   2061 	different MPFR versions (or this would be an ABI change).
   2062 
   2063 2022-05-17  Vincent Lefevre  <vincent (a] vinc17.net>
   2064 
   2065 	For version-ext.sh, use "$SED" instead of "sed".
   2066 
   2067 	* tests/Makefile.am: pass $SED to version-ext.sh.
   2068 	* version-ext.sh: use $SED (default to "sed").
   2069 
   2070 2022-05-17  Vincent Lefevre  <vincent (a] vinc17.net>
   2071 
   2072 	Fixed version-ext.sh when in an origin/* remote branch.
   2073 
   2074 2022-05-13  Vincent Lefevre  <vincent (a] vinc17.net>
   2075 
   2076 	Tests: the check of subnormal support is done when running the tests.
   2077 
   2078 	The check of support for double and float subnormals was done at
   2079 	configure time, but it could not be done when cross-compiling.
   2080 	Since it is useful only for the tests, it is better to do it when
   2081 	running the tests.
   2082 
   2083 	* tests/tests.c: added have_subnorm_dbl() and have_subnorm_flt()
   2084 	  functions to check support for double and float subnormals;
   2085 	  removed such a check from mpfr_test_init().
   2086 	* tests/mpfr-test.h: declare these functions.
   2087 	* tests/tget_flt.c: use have_subnorm_flt() instead of HAVE_SUBNORM_FLT.
   2088 	* tests/tset_d.c, tests/tsprintf.c: removed the useless test of
   2089 	  HAVE_SUBNORM_DBL (this was a minor optimization).
   2090 	* acinclude.m4: updated comment about the check of subnormal support;
   2091 	  minor improvement in the check for float subnormals.
   2092 	  Note: keep the check just for build information (it might be useful
   2093 	  for debugging or in case of a related bug report).
   2094 	* tools/mpfrlint: check that the HAVE_SUBNORM_* macros are not used.
   2095 
   2096 2022-05-13  Vincent Lefevre  <vincent (a] vinc17.net>
   2097 
   2098 	[acinclude.m4] Updated comment about the check of subnormal numbers.
   2099 
   2100 	* Removed text about DBL_HAS_SUBNORM and FLT_HAS_SUBNORM (which
   2101 	  was added in commit 3ee30bcf34bfb5d042e5a1aa9b7cf8a42b51cb91
   2102 	  on 2019-10-01) since these macros should be made obsolescent:
   2103 	  https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2981.htm
   2104 	  And their use would be incorrect in C++ (different meaning):
   2105 	  https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2988.pdf
   2106 	* A bit more details.
   2107 	* Added a FIXME for better cross-compiling support.

   2111 	doc/mpfr.texi: Updated the month.
   2112 
   2113 	[NEWS] Mention the fixes of the macros of the custom interface.
   2114 
   2115 2022-05-10  Vincent Lefevre  <vincent (a] vinc17.net>
   2116 
   2117 	Improved 2 macros of the custom interface and updated manual.
   2118 
   2119 	* src/mpfr.h: The mpfr_custom_init() and mpfr_custom_move() macros
   2120 	  could not be used in contexts where an expression was expected.
   2121 	  This limitation was not necessary and is now removed.
   2122 	* doc/mpfr.texi: In commit 743a63c480318f60ac2a953007bac08f37b7d71d,
   2123 	  the manual was clarified about the macros of the custom interface,
   2124 	  i.e. behaving like macros, which may evaluate arguments multiple
   2125 	  times or none. This was incomplete and error prone, in addition
   2126 	  to being undocumented in the current MPFR versions. Almost all
   2127 	  issues have now been fixed (the only minor limitation is that the
   2128 	  mpfr_custom_init_set() macro is not usable in contexts where an
   2129 	  expression is expected, but this cannot yield unnoticed bugs).
   2130 	  So, changed the manual to reflect these fixes and added an item
   2131 	  in Section "API Compatibility" (also removed an obsolete comment
   2132 	  about that from src/mpfr.h).
   2133 
   2134 2022-05-08  Vincent Lefevre  <vincent (a] vinc17.net>

   2142 2022-05-06  Vincent Lefevre  <vincent (a] vinc17.net>
   2143 
   2144 	In comments, changed "stack interface" to "custom interface".
   2145 
   2146 	* src/mpfr.h: changed "stack interface" and "mpfr_stack interface"
   2147 	  to "(the) custom interface".
   2148 	* src/stack_interface.c: changed "mpfr_stack" to "custom interface".
   2149 
   2150 	The mpfr_stack_ prefix was changed to mpfr_custom_ in 2005
   2151 	(see commit 0a010e55364d1cc3681273eee70c91dab0a61946) and
   2152 	the MPFR manual says "Custom Interface".

   2154 2022-05-06  Vincent Lefevre  <vincent (a] vinc17.net>
   2155 
   2156 	Other corrections about the custom interface.
   2157 
   2158 	This time, the build of tstckintc was failing with "gcc -Wc++-compat"
   2159 	because __cplusplus is not defined.
   2160 
   2161 	* tests/tstckintc.c: use the same solution as already done in
   2162 	  tcopysign.c (commit 3dbf3387669030b264317202806fc3d938704618),
   2163 	  i.e. ignore -Wc++-compat with "GCC diagnostic" pragmas when
   2164 	  testing with void * arguments.
   2165 	  Also simplified the code thanks to the VOIDP_CAST macro that
   2166 	  was introduced at that time (cast to void * except in C++):
   2167 	  commit 9076e47ceb41c60cab526870757f2098ced5c26d.
   2168 
   2169 	Everything should now be OK.

   2171 2022-05-06  Vincent Lefevre  <vincent (a] vinc17.net>
   2172 
   2173 	Other corrections about the custom interface.
   2174 
   2175 	In C++, implicit pointer conversions are forbidden. This made the
   2176 	build of tstckintc fail with g++ and -DMPFR_USE_NO_MACRO in CFLAGS.
   2177 
   2178 	* src/mpfr.h: do not attempt to support implicit pointer conversions
   2179 	  with a C++ compiler in the macros, since this is not supported by
   2180 	  the functions, i.e. removed 2 useless casts; this is a bit like the
   2181 	  code like before commit 9f94e0311ed53d0c64d4fbca249d19cc4888027e.
   2182 	* tests/tstckintc.c: test a "void *" argument instead of mpfr_ptr only
   2183 	  in C, not C++ (which cannot work if -DMPFR_USE_NO_MACRO is used).
   2184 	  Note: for newx and newx2, revert to the code that was before the
   2185 	  commit mentioned above.

   2199 	Fixed build failure of user code using mpfr_custom_get_kind() / g++.
   2200 
   2201 	* src/mpfr.h: added missing cast in the mpfr_custom_get_kind() macro
   2202 	  (invalid C++ code, but this is in a GNU __extension__ block, thus
   2203 	  unfortunately, it was not detected by "gcc -Werror=c++-compat";

   2208 2022-05-05  Vincent Lefevre  <vincent (a] vinc17.net>
   2209 
   2210 	Fixed issues with the macro versions of the custom interface.
   2211 
   2212 	* src/mpfr.h: fixed issues with the mpfr_custom_* macros:
   2213 	    - a "void *" argument instead of mpfr_ptr could make the
   2214 	      compilation fail (with the function, the conversion is
   2215 	      implicit, thus this should be accepted by the macro);
   2216 	    - some arguments could be evaluated 0 times, which is wrong
   2217 	      if their evaluation has side effects.
   2218 	* tests/tstckintc.c: added various tests to check these kinds
   2219 	  of issues.
   2220 
   2221 2022-05-05  Vincent Lefevre  <vincent (a] vinc17.net>

   2223 	Avoid a -Wsign-conversion warning that could occur in user code.
   2224 
   2225 	Issue reported by Andreas Enge concerning PariTwine.
   2226 
   2227 	* src/mpfr.h: added a cast in the mpfr_custom_get_size() macro so that
   2228 	  a size_t * size_t product is done instead of mpfr_prec_t * size_t
   2229 	  (where mpfr_prec_t is signed and size_t is unsigned, triggering a
   2230 	  warning when GCC's -Wsign-conversion is used).

   2232 2022-05-05  Vincent Lefevre  <vincent (a] vinc17.net>
   2233 
   2234 	Fixed mpfr_custom_get_size() macro and added non-regression test.
   2235 
   2236 	* src/mpfr.h: added missing cast in mpfr_custom_get_size() macro.
   2237 	* tests/tstckintc.c: added testcases (would fail on LP64 platforms).

   2244 
   2245 	Updated TODO to improve mpfr_pow_si/sj for negative n.
   2246 
   2247 	I thought that there would be some drawbacks with the underflow

   2276 
   2277 	Note: these are the same as in the 4.1 branch (commit 8f357dd48).
   2278 	So the ULONG2LONG macro was not necessary, but let's keep it for

   2285 
   2286 	* For n odd, generate negative values y (thus x) with a probability
   2287 	  1/2 (instead of a very low probability), as there is no reason to
   2288 	  favor positive values in this case.
   2289 	* Added bad_cases tests of mpfr_pow_si with n negative (with the help

   2345 	  (integer overflow on -n, triggered by the generic tests).
   2346 	* tests/trootn_si.c: added generic tests.

   2353 
   2354 	To get a random unsigned long, randlimb() is currently used, but with
   2355 	mini-gmp, a limb may be shorter than an unsigned long, so that one
   2356 	does not get all the possible "unsigned long" values. So these new
   2357 	randulong() and randlong() functions should now be used instead.
   2358 
   2359 2022-04-05  Vincent Lefevre  <vincent (a] vinc17.net>
   2360 
   2361 	Define a ULONG2LONG() macro to convert from unsigned long to long.

   2365 	  * doc/README.dev: mention this macro (the technique was already
   2366 	    described).
   2367 	  * src/log_ui.c: use this macro instead of non-portable code due to
   2368 	    the case n = LONG_MAX + 1.

   2400 
   2401 	In the tests directory:
   2402 	* mpfr-test.h: define RAND_BOOL() macro, with type int.
   2403 	* mpfr-test.h and various .c files: replace "randlimb () & 1" and

   2407 2022-04-04  Vincent Lefevre  <vincent (a] vinc17.net>
   2408 
   2409 	In the tests, fixed "randlimb () % 1", mistaken for "randlimb () & 1".
   2410 
   2411 	This occurred only in tests/tfmma.c (5 occurrences), with the
   2412 	consequence of fewer cases of different kinds in the tests.
   2413 
   2414 	Such a kind of mistake is now detected by mpfrlint (commit 2a90f0c91).

   2636 
   2637 	tests/Makefile.am: modified output_info to output:
   2638 	  * the detected branch, which also works in detached HEAD state
   2639 	    (for old commits that can be found in multiple branches,
   2640 	    "master" is prefered over the other branches);
   2641 	  * the total commit count;
   2642 	  * the commit id (hash).

   2644 2021-11-22  Vincent Lefevre  <vincent (a] vinc17.net>
   2645 
   2646 	Add git info with "git describe" for "make check" (to be improved).
   2647 
   2648 	tests/Makefile.am: in output_info, add git info, but this does not
   2649 	output the branch. For instance, on master, one gets something like
   2650 	"4.1-root-491-g2933fad3a", and something similar on the 4.1 branch.
   2651 	As the solution needs to work in detached HEAD state, we may want to
   2652 	add *-branch tags to identify the first commit of a branch, and use
   2653 	  git describe --match '*-branch'
   2654 	instead of
   2655 	  git describe --match '*-root'

   2667 
   2668 	Otherwise one gets a grave accent (thus "s  l" cannot be found).
   2669 	If the "" is still an issue, one could alternatively use
   2670 	  \pdfglyphtounicode{lscript}{006C}

   2915 	Note that len == 0 is possible when outputting an integer 0 (either a

   2920 	  * Otherwise, there should be no side effects since the code was valid
   2921 	    for len == 0, possibly except with LTO (very unlikely, though).

   3029 	case, mpfr_equal_p is safer, in particular if the code around changes;
   3030 	and this is more readable too).

   3054 	The standard just says that __LINE__ in an integer constant. So its
   3055 	type might be larger than int, even though the value is representable
   3056 	in an int (like in MPFR). This concerns logging code, only available

   3086 	Get rid of obsolescent AC_HEADER_TIME. Cleanup about sys/time.h usage.
   3087 
   3088 	The AC_HEADER_TIME macro is obsolescent in autoconf 2.69 (2012),
   3089 	and autoconf 2.71 (2021) outputs a warning, which makes autogen.sh
   3090 	fail due to "--warnings=all,error", so let's avoid the warnings.
   3091 	This macro defines TIME_WITH_SYS_TIME, used only in tests/tests.c
   3092 	(but actually not needed). We actually have two cases:
   3093 	  1. HAVE_GETTIMEOFDAY is defined: we use gettimeofday(), which
   3094 	     needs <sys/time.h>.
   3095 	  2. Otherwise: we use time(), which needs <time.h>.
   3096 
   3097 	Based on that, we can simplify the condition in tests/tests.c for
   3098 	the inclusion of time-related headers, and we no longer need to
   3099 	check the <sys/time.h> availability. If gettimeofday() is defined
   3100 	but <sys/time.h> is not available (which shouldn't occur), then
   3101 	the current gettimeofday() usage may be incorrect anyway.
   3102 
   3103 	Changes:
   3104 	  * acinclude.m4:
   3105 	      - no longer use AC_HEADER_TIME;
   3106 	      - no longer check the sys/time.h header.
   3107 	  * tests/tests.c: simplify the inclusion of time-related headers.

   3136 	[tests/{tset_si.c,tset_sj.c}] Fix when -DMPFR_USE_NO_MACRO is used.
   3137 
   3138 	The mpfr_get_exp() function checks that the argument is a regular
   3139 	number, but the corresponding macro doesn't. The test code was
   3140 	calling mpfr_get_exp() on 0, thus failed with MPFR_USE_NO_MACRO
   3141 	defined. Here, the code was correct with the macro, because the
   3142 	value was not used for the particular case 0.
   3143 
   3144 	This is fixed by testing 0 earlier (and doing a goto, but the code
   3145 	has fewer tests and should be simpler to understand). Moreover,
   3146 	mpfr_get_exp has been replaced by MPFR_GET_EXP, so that the argument
   3147 	is checked with --enable-assert.

   3169 
   3170 	These casts make the build of these tests fail with a C++ compiler.
   3171 	But this means that the use of macros will not introduce any issue
   3172 	concerning the type of the arguments, i.e. with a C++ compiler, the
   3173 	tests are still complete after this change.
   3174 
   3175 	However, GCC's -Werror=c++-compat still cannot be used.
   3176 	To avoid this issue, diagnostic pragmas will be needed.

   3372 2021-02-09  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   3375 
   3376 2021-02-08  Vincent Lefvre  <vincent (a] vinc17.net>
   3377 
   3378 	[src/mpfr.h] Updated comments on the types for mpfr_prec_t/mpfr_exp_t.
   3379 
   3380 	  * For mpfr_prec_t, removed the comment saying that under Windows 64,
   3381 	    "long long" could be used (this would imply that mpfr_prec_t and
   3382 	    mpfr_exp_t will not fit in a long, and this is not supported yet,
   3383 	    see below).
   3384 
   3385 	  * For mpfr_exp_t and _MPFR_EXP_FORMAT == 4, changed an unclear note
   3386 	    and added other information; in particular, this value is currently
   3387 	    not supported since the MPFR code assumes that mpfr_exp_t fits in a
   3388 	    long.
   3389 
   3390 2021-02-08  Vincent Lefvre  <vincent (a] vinc17.net>
   3391 
   3392 	[tests] Added texp2m1 and texp10m1 to svn:ignore property.
   3393 
   3394 	[src/jyn_asympt.c] Use mpfr_set4 instead of mpfr_set or mpfr_neg.
   3395 
   3396 	[tests/tj0.c] Latest test: also check the flags.
   3397 
   3398 	[src/digamma.c] Added a comment about the bug fixed in r14399.
   3399 
   3400 	[tests/tdigamma.c] Latest test: also check the flags.
   3401 
   3402 	[tests/tdigamma.c] Moved the r14399 test to its own test function.
   3403 	Note: for this one, there is no need to use the maximum exponent range.
   3404 
   3405 	[src/digamma.c] Use MPFR_NOTZERO instead of !MPFR_IS_ZERO.
   3406 
   3407 2021-02-08  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   3415 2021-02-08  Vincent Lefvre  <vincent (a] vinc17.net>
   3416 
   3417 	[src/digamma.c] Fix: increased GUARD from 20 to 30.
   3418 	[tests/tdigamma.c] Added 2 precisions for which GUARD=20 is not
   3419 	sufficient, yielding a "too much memory" error.
   3420 
   3421 2021-02-07  Vincent Lefvre  <vincent (a] vinc17.net>
   3422

   3429 2021-02-06  Vincent Lefvre  <vincent (a] vinc17.net>
   3430 
   3431 	[src/digamma.c] Added a FIXME for mpfr_digamma_positive: q can be
   3432 	too large, e.g. equal to the maximum exponent!
   3433 
   3434 	[src/digamma.c] In mpfr_digamma_positive, log the value of q.
   3435 
   3436 	[src/digamma.c] In mpfr_digamma_positive, do not compute the precision q
   3437 	until we are certain that it will be used.
   3438 
   3439 	[src/digamma.c] In mpfr_digamma_positive, added an assertion, as a
   3440 	precision is set from the exponent of x, and I suppose that it may
   3441 	be larger than MPFR_PREC_MAX when mpfr_exp_t > mpfr_prec_t.
   3442 
   3443 	[tests/tdigamma.c] Added testcase for a bug found by test_generic.
   3444 
   3445 	[tests/tgeneric.c] Added debug info.

   3458 
   3459 	[TODO] Added mpfr_mul_uj and mpfr_mul_sj.
   3460 
   3461 	[src/log.c] Optimization: avoid a temporary variable for a*2^m;
   3462 	use an alias to a instead. In corner cases, this could yield a
   3463 	new internal TMD for the mpfr_div when the precision of a is
   3464 	very large, but this is avoided by changing the RNDN to RNDF.
   3465 	The error bound of 2 ulp on the mpfr_div should still be valid
   3466 	(it should now actually be 1 ulp).
   3467 
   3468 2021-02-05  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   3469 
   3470 	added new function mpfr_exp2m1 for 2^x-1
   3471 
   3472 2021-02-05  Vincent Lefvre  <vincent (a] vinc17.net>
   3473 
   3474 	[tests/tversion.c] Fixed length modifier in error messages.
   3475 
   3476 	[src/log10p1.c] In mpfr_log10p1_small: an "else" case is better than
   3477 	a "goto"; do not initialize inex to an arbitrary value.
   3478 
   3479 	[src/compound.c] Exact cases: additional detail in the comment.
   3480 
   3481 	[src/compound.c] Exact cases: this is simpler without a separate
   3482 	function (the t = 0 was artificial). Added full explanations.
   3483 
   3484 2021-02-05  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   3485 
   3486 	[src/compound.c] removed FIXME corresponding to previous commit
   3487 
   3488 	[src/compound.c] fixed infinite loop for exact results like compound(0.5,2)
   3489 			 which are not powers of 2
   3490 
   3491 2021-02-05  Vincent Lefvre  <vincent (a] vinc17.net>
   3492 
   3493 	[src/compound.c] Fixed 2 issues with mpfr_compound_near_one:
   3494 	  * this function must be called in the extended exponent range,
   3495 	    to be sure that 1 is representable;
   3496 	  * it wasn't setting the inexact flag, and this is now done via
   3497 	    mpfr_check_range.
   3498 
   3499 	[src/compound.c] Added missing MPFR_ZIV_FREE before the "return" in
   3500 	the Ziv loop.
   3501 
   3502 	[tests/tcompound.c] Added generic tests with n = 2 and n = 3.
   3503 	They trigger a failure: bad inexact flag for mpfr_compound2.
   3504 
   3505 	[src/compound.c] Added a FIXME: possible infinite loop when the result
   3506 	is exact.
   3507 
   3508 	[src/compound.c] Optimize the easy case n = 1.
   3509 
   3510 	[src/compound.c] Special cases: fixed compound(-Inf,0) and improved
   3511 	comments.
   3512 
   3513 	[tests/tcompound.c] More tests of compound(x,n) for x < -1, showing
   3514 	a failure on compound(-Inf,0).
   3515 
   3516 	[doc/README.dev] Note that the logging feature (--enable-logging)
   3517 	needs GCC to build MPFR, and it is not available with mini-gmp,
   3518 	since mpfr_fprintf cannot be defined with mini-gmp.

   4180 	  * The code isn't valid with 16-bit int (allowed by ISO C). So,
   4181 	    make sure with MPFR_STAT_STATIC_ASSERT that unsigned int is
   4182 	    large enough for invert_limb_table2.
   4183 	    Note: since the code is under "#if GMP_NUMB_BITS == 64",
   4184 	    this is unlikely to affect any system in practice, as
   4185 	    GMP_NUMB_BITS == 32 (or 16, if supported) should be better
   4186 	    on such a system.

   4272 
   4273 	[tests/tset_z_2exp.c] Added some tests in a reduced exponent range (and
   4274 	improved existing tests).
   4275 	Note: Due to an incorrect change in set_z_2exp.c r14145, various tests
   4276 	are failing with mini-gmp (for which mpfr_set_z_2exp is used more often
   4277 	because a long does not fit into a limb) in unusual exponent ranges. So
   4278 	such tests were obviously missing in tset_z_2exp.c before this commit.
   4279 
   4280 2020-09-25  Vincent Lefvre  <vincent (a] vinc17.net>
   4281

   4285 
   4286 	[doc/README.dev] Added how to convert an unsigned integer to the

   4288 	modular arithmetic) but in a portable way.

   4293 
   4294 	[tests/tset_z_2exp.c] Added another test that fails with just
   4295 	"-m32 -fsanitize=undefined -fno-sanitize-recover".
   4296 	This corresponds to what is described in the FIXME in src/set_z_2exp.c
   4297 	(about the modified tnrandom.c test yielding an integer overflow).
   4298 
   4299 	[tests/tset_z_2exp.c] Added a test that triggers an integer overflow
   4300 	in set_z_2exp.c with MPFR_CHECK_LARGEMEM=1 when MPFR is compiled with
   4301 	"-m32 -fsanitize=undefined -fno-sanitize-recover -D_MPFR_EXP_FORMAT=4"
   4302 	in CFLAGS:

   4306 2020-09-23  Vincent Lefvre  <vincent (a] vinc17.net>
   4307 
   4308 	[src/exp2.c] Added support for -D_MPFR_EXP_FORMAT=4 in the 32-bit ABI,
   4309 	i.e. 32-bit long, so that the MPFR compilation no longer fails due to
   4310 	a static assertion in this file. Note: many tests fail (not texp2),
   4311 	but at least this allows some testing of various functions.
   4312 
   4313 2020-09-23  Vincent Lefvre  <vincent (a] vinc17.net>
   4314 
   4315 	[INSTALL] Update concerning MinGW and the __USE_MINGW_ANSI_STDIO macro.
   4316 
   4317 	The change done in r13668 seems to be a bit wrong (at least unclear).
   4318 	This was done after finding
   4319 	https://fr.osdn.net/projects/mingw/lists/archive/users/2019-January/000199.html
   4320 	saying that __USE_MINGW_ANSI_STDIO became deprecated, during a
   4321 	discussion on the vsnprintf() behavior:
   4322 	https://gmplib.org/list-archives/gmp-bugs/2020-January/004716.html
   4323 
   4324 	However, it seems that printf() conformity issues have completely been
   4325 	resolved only recently, in version 8.
   4326 	http://mingw-w64.org/doku.php says:
   4327 	  Version 8 has been released
   4328 	  v8.0.0: 2020-09-18
   4329 	  Notable changes:
   4330 	  [...]
   4331 	    * __USE_MINGW_ANSI_STDIO now automatically enabled in C99 and C11
   4332 	      mode when not using UCRT by Pali Rohr
   4333 	  [...]
   4334 
   4335 	Compiling
   4336 	  #include <stdio.h>
   4337 	  int main (void) { volatile double d = -1.25; printf ("%e\n", d); }
   4338 	gives with mingw-w64 version 7: -1.250000e+000
   4339 	  and with mingw-w64 version 8: -1.250000e+00
   4340 
   4341 	So, when testing MPFR with mingw-w64 version 8 but with GMP still built
   4342 	with mingw-w64 version 7 (and static libraries), one gets a failure in
   4343 	tsprintf:
   4344 	  Error in mpfr_vsprintf (s, "%e", ...);
   4345 	  expected: "-1.250000e+00"
   4346 	  got:      "-1.250000e+000"
   4347 	because the expected result has changed (it comes from sprintf used in
   4348 	the MPFR test, which is now ISO-compliant).

   4350 2020-09-18  Vincent Lefvre  <vincent (a] vinc17.net>
   4351 
   4352 	[src/set_z_2exp.c] Added a FIXME: possible integer overflow, which
   4353 	can be reproduced with a 32-bit ABI by defining MPFR_PREC_MAX as
   4354 	((mpfr_prec_t) ((((mpfr_uprec_t) -1) >> 1) - 63)) and in tnrandom.c,
   4355 	using "test_special (MPFR_PREC_MAX);".
   4356 
   4357 2020-09-16  Vincent Lefvre  <vincent (a] vinc17.net>
   4358 
   4359 	[doc/mpfr.texi] Updated the month.
   4360 
   4361 	[doc/mini-gmp] Say that the build with mini-gmp may require ISO C99+
   4362 	features (as "long long" is currently needed by src/get_ld.c in the
   4363 	case GMP_NUMB_BITS == 8).
   4364 
   4365 	For consistency, changed "C89" to "C90" in comments of *.{c,h} files.
   4366 
   4367 	[doc/mpfr.texi] Changed C89 to C90, as when mentioning ISO, one must
   4368 	say C90 (C89 is the ANSI version). The GCC manual uses "C90" rather
   4369 	than "C89", so this is probably better anyway.
   4370 
   4371 	[src/get_ld.c] Bug fix with GMP_NUMB_BITS == 8 (thus mini-gmp) and
   4372 	32-bit long (e.g. with -m32 on x86_64).
   4373 
   4374 2020-09-15  Vincent Lefvre  <vincent (a] vinc17.net>
   4375 
   4376 	Renamed some .c files for consistency:
   4377 	  src/get_z_exp.c       src/get_z_2exp.c
   4378 	  src/set_z_exp.c       src/set_z_2exp.c
   4379 	  tests/tset_z_exp.c    tests/tset_z_2exp.c
   4380 	and updated src/Makefile.am and tests/Makefile.am files.
   4381 
   4382 	[src/random_deviate.c] The latest change r14123 was actually incorrect:
   4383 	the real issue was non-portable code (with an incorrect comment) to
   4384 	convert an unsigned integer to a signed, negative integer. Incorrect
   4385 	behavior could occur with some C implementations and/or when mpfr_exp_t
   4386 	does not have the same size as long. So, fixed this portability issue,
   4387 	and avoid an assertion failure in a very rare case.
   4388 
   4389 	[src/random_deviate.c] Corrected an assertion.  Test failures.
   4390 
   4391 	[tests/tests.c] Added a note about tests done in "src/init2.c".
   4392 
   4393 	[src/init2.c] Check that __MPFR_EXP_MAX  == MPFR_EXP_MAX too.
   4394 
   4395 	[tests/tget_z.c] Updated comment to mention that mpfr_get_z_2exp is
   4396 	tested by this file.
   4397 
   4398 	[src/mpfr-mini-gmp.c] Fixed bug in gmp_urandomb_ui when the parameter n
   4399 	is equal to the width of unsigned long.
   4400 	Note: This case occurs in function random_deviate_generate() from
   4401 	src/random_deviate.c with a 32-bit ABI (thus 32-bit unsigned long)
   4402 	since n = W, which is defined as 32.
   4403 
   4404 2020-09-14  Vincent Lefvre  <vincent (a] vinc17.net>
   4405 
   4406 	[src/mpfr-mini-gmp.c] Simplified gmp_randseed_ui (note: the code in
   4407 	r14114 and r14115 was not the intended one due to the wrong variable
   4408 	in srand).
   4409 
   4410 	[src/mpfr-mini-gmp.c] Corrected latest change for gmp_randseed_ui.
   4411 
   4412 	With mini-gmp, use the standard rand() and srand() functions instead of
   4413 	the POSIX (thus less portable) lrand48() and srand48().

   4437 	  mpfr_t        to  mpfr_ptr
   4438 	(except for mpfr_t *), as this is equivalent (the array is converted
   4439 	to a pointer) and the mpfr_srcptr/mpfr_ptr form is the usual one.

   4441 2020-08-20  Vincent Lefvre  <vincent (a] vinc17.net>

   4472 	[doc/mpfr.texi] Updated the month.
   4473 
   4474 	[doc/mpfr.texi] In the paragraph about cases that are hard to round,

   4477 2020-07-20  Vincent Lefvre  <vincent (a] vinc17.net>
   4478 
   4479 	[doc/README.dev] Added a paragraph on the issue with GCC and
   4480 	conversions between binary and decimal types.
   4481 
   4482 	[src/get_d128.c] Updated FIXME comment (after r14087).
   4483 
   4484 	[src/get_d128.c] Removed unused variable due to r14087.
   4485 
   4486 	[src/get_d128.c] For the special values, avoid double to _Decimal128
   4487 	conversions, as for such conversions, GCC generates from 2 to 3 MB in
   4488 	the shared library when the decimal encoding is BID, and there will be
   4489 	no fix in GCC:
   4490 	  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96173
   4491 	We now use computations on _Decimal128 constants directly, which could
   4492 	thus be done at compile time. We expect no problems similar to double,
   4493 	as the _Decimal128 implementation should follow the IEEE 754 rules.
   4494 	This commit should avoid a large part of the problem reported at:

   4501 2020-07-13  Vincent Lefvre  <vincent (a] vinc17.net>
   4502 
   4503 	[tests/tests.c] Simplified the d_trace and ld_trace functions:
   4504 	we do not need a union (with its potentional padding) as there
   4505 	are no aliasing issues with unsigned char.
   4506 
   4507 	[tests/tset_ld.c] Fixed mpfr_out_str usage in error messages
   4508 	(see the change in r12520).
   4509 
   4510 	[tests/tget_ld_2exp.c] Corrected a function call in an error message.

   4524 
   4525 	[src/jyn_asympt.c] Added an assertion.
   4526 
   4527 	[doc/README.dev] In the MPFR_CHECK_EXPENSIVE description, say that
   4528 	  --enable-assert=full should not be used (too expensive, not needed).
   4529 	[tests/tjn.c] Added a related comment for the expensive bug20200703
   4530 	  test (which may take more than 1 hour with --enable-assert=full).
   4531 
   4532 	[tests/tjn.c] Corrected indentation.

   4546 	[src/jyn_asympt.c] Added a log message.
   4547 
   4548 	[tests/tjn.c] Added testcase for bug reported by Alex Coplan:
   4549 	  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96044
   4550 	mpfr_jn is very slow or doesn't terminate on (733333,733333).

   4553 
   4554 	[NEWS] For MPFR 4.1.0, added an item saying that TLS can safely be
   4555 	(re-)enabled on Sparc.
   4556 
   4557 2020-06-29  Vincent Lefvre  <vincent (a] vinc17.net>
   4558 
   4559 	[tests/mpfr-test.h] Avoid a GCC bug on Sparc, at least when using TLS.
   4560 	The MPFR library itself is not affected, only a particular test. Normal
   4561 	code using the MPFR library should not be affected either, as the bug
   4562 	occurs when accessing __gmpfr_flags directly (and the public mpfr.h
   4563 	header file does not provide any macro that accesses an internal
   4564 	variable directly). So a workaround for the tests is the best solution.

   4591 
   4592 	[doc/mpfr.texi] Corrected and detailed the description of
   4593 	mpfr_get_str_ndigits.
   4594 
   4595 	[src/get_str.c] Since the mpfr_get_str_ndigits function is in the
   4596 	public API, use MPFR_ASSERTN instead of MPFR_ASSERTD on the condition
   4597 	on the argument b in order to get an assertion failure (by default)

   4613 
   4614 	[src/digamma.c] Added a FIXME.
   4615 
   4616 	[src/digamma.c] Replaced mpfr_get_exp by MPFR_GET_EXP.
   4617 
   4618 	[src/digamma.c]
   4619 	  * Replaced some MPFR_EXP by MPFR_GET_EXP to check that the MPFR number
   4620 	    has an exponent (i.e. it is not a special value).
   4621 	     Assertion failure in tdigamma (on x86_64).
   4622 	    Note: this might be the cause of an unexpected loop (infinite loop?)
   4623 	    on a Debian 10.4 POWER9 machine:
   4624 	      https://sympa.inria.fr/sympa/arc/mpfr/2020-06/msg00025.html
   4625 	  * Added an integer overflow check on a precision.

   4636 
   4637 	[tests/tset_ld.c] bug_20160907 (tests on subnormals):
   4638 	  * Replaced an assertion by a test with detailed output.
   4639 	  * Corrected a value in a test, which did not match the comment.
   4640 
   4641 	[tests] Skip tabort_defalloc1 and tabort_defalloc2 under Valgrind, as
   4642 	Valgrind complains due to the large allocation size.
   4643 	  * mpfr-test.h, tests.c: added tests_run_within_valgrind() function to
   4644 	    guess whether the test runs within Valgrind.
   4645 	  * tabort_defalloc1.c, tabort_defalloc2.c: skip the test (exit code 77)
   4646 	    if this function returns true.
   4647 
   4648 	[configure.ac] Improvements concerning the default CFLAGS with GCC.

   4652 	    (with some autoconf related fixes).
   4653 	  * Output the $CFLAGS value that is eventually used.
   4654 
   4655 	[configure.ac] No longer add -Wc++-compat to CFLAGS when the compiler
   4656 	is GCC not in C++ mode (reverting the change done in r13406) since this

   4675 
   4676 	[tests/tests.c] Removed a useless "#include <errno.h>" (added in r5252,
   4677 	useless since r5253).
   4678 
   4679 	[tests/tfpif.c] Fixed a bug (in the test) detected on AIX[*], where
   4680 	an fclose failed due to a previous read failure. At the same time,
   4681 	check that a read failure no longer occurs. Note: the read failure
   4682 	made mpfr_fpif_import fail, but this is a test where it is expected
   4683 	to fail, i.e. we now check that it fails for a good reason.
   4684 	[*] gcc119.fsffrance.org on the GCC Compile farm.

   4729 
   4730 	[NEWS] Added release name for 4.1.0: "pinards  la crme".
   4731 
   4732 	[doc/mini-gmp] English usage improvement.
   4733 
   4734 	Fixed 2 issues with tests/tvalist.c:
   4735 	  1. When building with mini-gmp (--with-mini-gmp=DIR) without
   4736 	     optimizations (-O0), the build of tvalist was failing because
   4737 	     the formatted output functions are not supported (this issue
   4738 	     wasn't noticed with optimizations due to dead code elimination).
   4739 	     Fix: this test is disabled with mini-gmp (not needed anyway).
   4740 	  2. Dead code elimination with optimizations partly broke the goal
   4741 	     of this test, i.e. checking that mpfr_vfprintf was available.
   4742 	     This dead code was introduced in r7648 "Make sure that fct is
   4743 	     used (avoid a warning)." (where fct = mpfr_vfprintf) but was
   4744 	     actually not sufficient.
   4745 	     Fix: call mpfr_vfprintf unconditionally, but on an empty string
   4746 	     in order to avoid output to stdout.
   4747 	In addition to these changes in tests/tvalist.c, src/mpfr-impl.h could
   4748 	be simplified as a consequence.
   4749 
   4750 	Removed '# undef HAVE_STDARG' before '# include "config.h"' when it
   4751 	was used, as it was not always undefined (e.g. in tests/tsprintf.c)
   4752 	and there are no reasons to undefine this macro specifically.
   4753 	Note: this code was introduced in r2665 (2004-02-06), perhaps for
   4754 	the MPFR build inside GMP, which has been dropped a long time ago.
   4755 
   4756 	[tests/tvalist.c] Updated a comment.
   4757 
   4758 	[tests/tvalist.c] Correction when config.h is used (code copied from
   4759 	src/inits.c).

   4767 	[NEWS] Typo in option name.
   4768 
   4769 	[src/mpfr-longlong.h]
   4770 	  * Updated comment about this file and the changes against GMP 6.2.0.
   4771 	  * Define __GMP_GNUC_PREREQ if it isn't defined (this is currently not
   4772 	    needed since it is defined in gmp.h as used also there, but this is
   4773 	    useful in case some future gmp.h version no longer defines it).
   4774 
   4775 	[src/mpfr-longlong.h] Update: applied the diff of GMP's longlong.h
   4776 	between GMP 6.1.0 and GMP 6.2.0, after reverting changesets 13251,
   4777 	11042, 11025, and 10727, as these changes are present in the diff.
   4778 
   4779 	[configure.ac] With mini-gmp, also check the availability of srand48.
   4780 
   4781 	[src/mpfr-mini-gmp.c] For gmp_randseed_ui, which uses srand48, use
   4782 	a portable version of the conversion from unsigned long to long.
   4783 
   4784 	[doc/mini-gmp] Note also that the random functions are not thread-safe.
   4785 
   4786 	[doc/mini-gmp] Major update.

   4790 2020-06-09  Vincent Lefvre  <vincent (a] vinc17.net>
   4791 
   4792 	[tests/tversion.c] Code style: replaced (mp_limb_t) -1 by MPFR_LIMB_MAX.
   4793 
   4794 	[src/mul_ui.c] Bug fix: in the code where MPFR_LONG_WITHIN_LIMB is
   4795 	not defined, update the flags (needed for the possible overflow).
   4796 
   4797 	[tests/tmul_ui.c] Added an overflow check that fails in MPFR_RNDZ with
   4798 	mini-gmp and mp_limb_t < long (e.g. "-DMINI_GMP_LIMB_TYPE=short").
   4799 
   4800 	[tests/tgeneric.c] In the MPFR_SUSPICIOUS_OVERFLOW case, output yprec.
   4801 
   4802 	[src/mpfr-impl.h] Changed the code that defines MPFR_LONG_WITHIN_LIMB
   4803 	in order to support mini-gmp with -DMINI_GMP_LIMB_TYPE=...
   4804 
   4805 	[src/get_ld.c] Fixed build failure with GMP_NUMB_BITS == 8 due to the
   4806 	use of uint64_t in src/get_ld.c, while <stdint.h> was not included:
   4807 	replaced it by "unsigned long long", which does not need a specific
   4808 	header (an exact 64-bit type is not needed, we just need at least a
   4809 	64-bit width, which unsigned long long is guaranteed to have).
   4810 	Note: unsigned long long may not be available with a pre-C99 compiler,
   4811 	but this is not worse than uint64_t. This limitation is currently OK
   4812 	as GMP_NUMB_BITS == 8 support is just for testing.
   4813 
   4814 	[acinclude.m4] Make MPFR_CHECK_MP_LIMB_T_VS_LONG and
   4815 	MPFR_CHECK_MP_LIMB_T_VS_INTMAX similar:
   4816 	  * Use AC_LINK_IFELSE in MPFR_CHECK_MP_LIMB_T_VS_LONG too: this
   4817 	    is safer than AC_COMPILE_IFELSE, as it will detect undefined
   4818 	    function-like macros.
   4819 	  * Define MPFR_USE_STATIC_ASSERT in MPFR_CHECK_MP_LIMB_T_VS_INTMAX
   4820 	    too in order to make sure that a static assertion is used (not
   4821 	    the MPFR_ASSERTN fallback).
   4822 	Note: These constitute redundant safeguards because if MPFR_ASSERTN
   4823 	is used, it will be regarded as a function since the macro is not
   4824 	defined in this context, and linking will fail as a consequence.
   4825 	But this redundancy will protect more against MPFR code evolution.
   4826 
   4827 	[acinclude.m4] Fixed MPFR_CHECK_MP_LIMB_T_VS_LONG macro by forcing
   4828 	MPFR_USE_STATIC_ASSERT to 1 before including mpfr-sassert.h, i.e.
   4829 	by requiring static assertions: because AC_COMPILE_IFELSE is used
   4830 	(i.e. just compiling, no linking), the test could incorrectly succeed
   4831 	when MPFR_USE_STATIC_ASSERT was not defined, i.e. whatever the value
   4832 	of "(mp_limb_t) -1 >= (unsigned long) -1"; indeed, in this case,
   4833 	MPFR_ASSERTN() was used instead of a static assertion, and since the
   4834 	macro was not defined here, MPFR_ASSERTN was regarded as a function
   4835 	(without a prototype), which was fine for compiling (except when the
   4836 	compiler is configured to regard warnings such as missing prototype
   4837 	as errors). In short, one could get "yes" while long was larger than
   4838 	mp_limb_t.
   4839 	Note: In uncommon cases (non-standard compiler...), one can still get
   4840 	"no" while a long fits in mp_limb_t, but this isn't much an issue as
   4841 	the MPFR code should work in such a case. Moreover, src/mpfr-impl.h
   4842 	will also have the chance to set MPFR_LONG_WITHIN_LIMB in practice.
   4843 
   4844 	Removed MPFR_DECL_STATIC_ASSERT macro as it was buggy, unused, rather
   4845 	useless, and it had drawbacks. Details:
   4846 	  * In src/mpfr-sassert.h, the default definition of this macro in the
   4847 	    MPFR_USE_STATIC_ASSERT case ended with a spurious ";". Since this
   4848 	    macro was unused, this wasn't noticeable... except in the configure
   4849 	    test for static assertions, which failed in some cases (e.g. with
   4850 	    CFLAGS="-std=c99 -pedantic-errors -Wno-error=overlength-strings")
   4851 	    for this reason, which had the effect to let MPFR_USE_STATIC_ASSERT
   4852 	    undefined, while static assertions were actually working.
   4853 	  * Still in src/mpfr-sassert.h, but when MPFR_USE_STATIC_ASSERT is not
   4854 	    defined, the MPFR_DECL_STATIC_ASSERT(c) expanded to nothing, which
   4855 	    would yield invalid code as
   4856 	      MPFR_DECL_STATIC_ASSERT(some_assertion);
   4857 	    would yield an extra ";" (about the same issue as above). Given
   4858 	    the fact that the portable MPFR_USE_STATIC_ASSERT code does not
   4859 	    work with this compiler, it is not clear whether this is fixable
   4860 	    in a completely reliable way.
   4861 	  * MPFR_DECL_STATIC_ASSERT can be replaced by MPFR_STAT_STATIC_ASSERT
   4862 	    after moving it to the statement section of a function, with almost
   4863 	    no drawbacks (just a bit readability in some cases?).
   4864 	  * When MPFR_USE_STATIC_ASSERT is not defined, MPFR_STAT_STATIC_ASSERT
   4865 	    will check the assertion at run time (for free, since the result is
   4866 	    known at compile time), while MPFR_DECL_STATIC_ASSERT would not be
   4867 	    able to do anything useful.
   4868 	Changes:
   4869 	  * acinclude.m4: removed the test of MPFR_DECL_STATIC_ASSERT.
   4870 	  * src/mpfr-sassert.h: removed MPFR_DECL_STATIC_ASSERT definitions.
   4871 	  * tune/tuneup.c: removed MPFR_DECL_STATIC_ASSERT redefinition.

   4875 	[acinclude.m4] MPFR_CHECK_MP_LIMB_T_VS_LONG: updated comment to say

   4877 	are not supported, but currently fails) would be incorrect.
   4878 
   4879 	[acinclude.m4] In MPFR_CHECK_MP_LIMB_T_VS_INTMAX, do the test only if

   4890 
   4891 	[acinclude.m4] MPFR_CHECK_DBL2INT_BUG test: avoid potentially reserved
   4892 	exit status.
   4893 
   4894 	[acinclude.m4] Fixed r13938: the new MPFR_C_REALFP_FORMAT macro also
   4895 	needs to take the printf length modifier in argument.
   4896 
   4897 	[acinclude.m4] Improved the code to determine the format of double,
   4898 	resolving the FIXME. The issue was that it used an AC_RUN_IFELSE,
   4899 	so that the format could not be determined when cross-compiling.
   4900 	The code to determine the format of long double did not have such
   4901 	an issue: the object file was analyzed by an awk script. Since a
   4902 	long double can have the same format as a double, this code was
   4903 	already able to recognize a double, in particular. So the change
   4904 	consisted in slightly adapting this code to accept the tested type
   4905 	as an argument ("double" or "long double", the mpfr_cv_ variable
   4906 	name being obtained thanks to AS_VAR_PUSHDEF) and reusing it for
   4907 	the detection of the format of double.
   4908 
   4909 	[acinclude.m4] MPFR_C_LONG_DOUBLE_FORMAT cleanup:
   4910 	  * Removed an unused AH_VERBATIM.
   4911 	  * Removed "not available" condition, no longer possible since r13936.
   4912 
   4913 	[acinclude.m4] Fix concerning r13935: also removed code that tested
   4914 	the availability of long double. This code was useless since it was
   4915 	just outputting "not available" if long double was missing, and one
   4916 	would get an error later since MPFR requires long double. But since
   4917 	long double is in ISO C89, it is useless to add a test just to return
   4918 	an error for pre-C89 compilers.
   4919 
   4920 	[acinclude.m4] Removed "AC_CHECK_TYPES([long double])", whose only
   4921 	  purpose is to define a HAVE_LONG_DOUBLE macro.
   4922 	[configure.ac] Removed HAVE_LONG_DOUBLE from the cleanup: no longer
   4923 	  needed with the change in acinclude.m4.

   4926 
   4927 	[configure.ac] Minor change in a comment.
   4928 
   4929 	Cleanup about the function detection by autoconf.
   4930 	  * acinclude.m4: removed the detection of memmove, memset and strtol,
   4931 	    which was not used (a macro "HAVE_..." was defined... to be removed
   4932 	    in configure.ac!); for AC_CHECK_FUNCS, remove options starting with
   4933 	    "-Werror" as they can yield a spurious failure due to the way this
   4934 	    test is done (this occurred on memmove and memset with GCC due to
   4935 	    builtins, and similar issues could still occur in practice with the
   4936 	    remaining functions in the AC_CHECK_FUNCS list).
   4937 	  * configure.ac: removed HAVE_STRTOL from the macro cleanup: no longer
   4938 	    needed since strtol has been removed from the AC_CHECK_FUNCS list.
   4939 
   4940 	[acinclude.m4] Minor improvement: in the MPFR_CHECK_GMP test, changed
   4941 	the exit status values 1..3 to 81..83 in order to avoid confusion, as
   4942 	low values can typically be returned in case of compile or link error.

   4962 
   4963 	Details on the bugs fixed:
   4964 	  * The code added in r13916 forgot a #include <limits.h> since this
   4965 	    code does a test on ULLONG_MAX. With the cleanup, <limits.h> is
   4966 	    already always included by mpfr-impl.h (early enough).
   4967 	  * In src/get_str.c and tests/memory.c, a #include "config.h" was
   4968 	    missing before #include "mpfr-intmax.h"; this issue would affect
   4969 	    platforms where "config.h" is needed and where <inttypes.h> or

   5154 	[INSTALL] update CompCert instructions
   5155 
   5156 2020-04-02  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   5157 
   5158 	[INSTALL] fixed CompCert instructions
   5159 
   5160 2020-04-02  Vincent Lefvre  <vincent (a] vinc17.net>
   5161 
   5162 	[tests/tset_ld.c] Reverted r13858: the check_overflow test was already
   5163 	in MPFR 4.0.1 and was succeeding on armv5tejl-unknown-linux-gnueabi,
   5164 	which had mpfr_cv_c_long_double_format='IEEE double, little endian'.
   5165 	The issue should be investigated.
   5166 	Note: MPFR_LDBL_MANT_DIG may be larger than the actual number of bits,
   5167 	but this should not cause a failure in the tests.
   5168 
   5169 	[tests/tget_ld_2exp.c] Proper fix: the bug20180904 test was designed
   5170 	for the x87 extended precision, so enable it only in this case.
   5171 
   5172 2020-04-02  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   5173 
   5174 	[tests/tsub.c] modify test_ubf() to always hit a current failing test
   5175 
   5176 2020-04-02  Vincent Lefvre  <vincent (a] vinc17.net>
   5177 
   5178 	[configure.ac] Fixed the change done in r13853 (about removed macros),
   5179 	making the code simpler and more maintainable at the same time.
   5180 
   5181 2020-04-02  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   5182 
   5183 	[INSTALL] added configuration for CompCert test
   5184 
   5185 2020-04-02  Vincent Lefvre  <vincent (a] vinc17.net>
   5186 
   5187 	[src/set_ld.c] Removed obsolete workaround due to LDBL_MAX being buggy
   5188 	on old i386 systems (the tests were not using this workaround).
   5189 
   5190 2020-04-02  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   5191 
   5192 	[tests/tget_ld_2exp.c] fixed for case where long double = double
   5193 	[tests/tset_ld.c]      likewise
   5194 
   5195 2020-04-02  Vincent Lefvre  <vincent (a] vinc17.net>
   5196 
   5197 	[configure.ac] Moved MPFR_CONFIGS invocation: MPFR_CONFIGS uses LDFLAGS,
   5198 	thus must be invoked after LDFLAGS has been determined completely.
   5199 
   5200 2020-04-02  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   5201 
   5202 	[INSTALL] now all tests pass with compcert
   5203 
   5204 	[acinclude.m4] added missing LDFLAGS for long double test
   5205 
   5206 2020-04-02  Vincent Lefvre  <vincent (a] vinc17.net>
   5207 
   5208 	[doc/README.dev] Added HAVE_ALLOCA description.
   5209 
   5210 	[configure.ac] Do not remove the HAVE_ALLOCA macro, which is now used
   5211 	by MPFR to determine the default MPFR_ALLOCA_MAX value.
   5212 
   5213 2020-04-02  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   5214 
   5215 	[INSTALL] update CompCert instructions
   5216 
   5217 2020-04-02  Vincent Lefvre  <vincent (a] vinc17.net>
   5218 
   5219 	[tests/tversion.c] Output whether MPFR is built with the GMP build,
   5220 	and the MPFR_ALLOCA_MAX value if not.
   5221 
   5222 	[src/mpfr-gmp.h] If HAVE_ALLOCA is not defined, i.e. if alloca() is
   5223 	not available (as detected by the configure script), then set the
   5224 	default MPFR_ALLOCA_MAX value to 0 so that alloca() is not used.
   5225 
   5226 2020-04-02  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   5227 
   5228 	[INSTALL] added instructions for CompCert
   5229 
   5230 2020-04-02  Vincent Lefvre  <vincent (a] vinc17.net>
   5231 
   5232 	[doc/README.dev] Updated MPFR_ALLOCA_MAX description.
   5233 
   5234 	[src/mpfr-gmp.h] When MPFR_ALLOCA_MAX = 0 (set at configure time),
   5235 	do not reference alloca() since we don't need it.
   5236 
   5237 2020-03-31  Vincent Lefvre  <vincent (a] vinc17.net>
   5238 
   5239 	[doc/mpfr.texi] About mpfr_printf with %Re and empty precision field,
   5240 	added a comment with URLs of the discussion and the bug report.
   5241 
   5242 2020-03-30  Vincent Lefvre  <vincent (a] vinc17.net>
   5243 
   5244 	[src/sub1.c] Typo in a comment.
   5245 
   5246 	[configure.ac] Updated message output when the gmp.h vs libgmp test
   5247 	fails: another cause may be that LD_RUN_PATH is not honored (problem
   5248 	seen under OpenBSD 6.6 / gcc302.fsffrance.org).
   5249 
   5250 2020-03-27  Vincent Lefvre  <vincent (a] vinc17.net>
   5251 
   5252 	[tests/tset_sj.c] Forgot a "#ifndef NPRINTF_J" for printf("%jd",...).
   5253 
   5254 	[src/set_uj.c] Fixed underflow detection.
   5255 
   5256 	[src/set_uj.c] Added early overflow detection to avoid a possible
   5257 	integer overflow. Added a FIXME (incorrect underflow detection).
   5258 
   5259 	[tests/tset_sj.c] Added tests of mpfr_set_sj_2exp and mpfr_set_uj_2exp
   5260 	in precision 3 with integers from -31 to 31 and exponents MPFR_EXP_MIN,
   5261 	MPFR_EMIN_MIN-7 to MPFR_EMIN_MIN, MPFR_EMAX_MAX-7 to MPFR_EMAX_MAX,
   5262 	MPFR_EXP_MAX-7 to MPFR_EXP_MAX (like in tset_si.c, see r13808), but
   5263 	also exponents INTMAX_MIN and INTMAX_MAX. This shows bugs in set_uj.c,
   5264 	to be fixed...
   5265 
   5266 	[src/set_sj.c] Coding style.
   5267 
   5268 	[src] Moved the definition of the numberof() macro from mpfr-gmp.h to
   5269 	mpfr-impl.h in order to always use our own. Also make sure that the
   5270 	type is signed, so that the value can be used in arbitrary expressions
   5271 	without the risk of silently switching to unsigned arithmetic.
   5272 
   5273 2020-03-26  Vincent Lefvre  <vincent (a] vinc17.net>
   5274 
   5275 	[tests/texpm1.c] Updated the bad_cases() parameters to increase the
   5276 	proportion of generated bad cases.
   5277 
   5278 	[tests/tset_si.c] Forgot a cast for MPFR_EXP_FSPEC argument.
   5279 
   5280 	[doc/mpfr.texi] Updated the month.
   5281 
   5282 	Consistency: "a UBF"  "an UBF" since UBF stands for "unbounded float".
   5283 
   5284 	[src/mpfr-impl.h] Updated UBF comment about aliasing rules.
   5285 
   5286 	[src/mpfr-impl.h] Updated UBF comment about aliasing rules.
   5287 
   5288 	[src/mpfr-impl.h] Bug fix (MPFR_ZEXP(x) as used for an assignment
   5289 	could yield undefined behavior on platforms where mpfr_exp_t has
   5290 	trap representations); this is also a general improvement.
   5291 
   5292 	[tests/tsub.c] Avoid the build failure with -Werror=strict-aliasing by
   5293 	replacing x[] by p[] (but this doesn't eliminate the problem itself).
   5294 
   5295 	[src/mpfr-impl.h] UBF: updated comment: this breaks aliasing rules, but
   5296 	there isn't any other acceptable solution.
   5297 	Note: when trying to build MPFR without --enable-assert, with GCC and
   5298 	CFLAGS="-O2 -Werror=strict-aliasing", the compilation of tests/tsub.c
   5299 	currently fails because of that.
   5300 
   5301 2020-03-25  Vincent Lefvre  <vincent (a] vinc17.net>
   5302 
   5303 	[tests/tsub.c] Fixed tests on UBF.
   5304 
   5305 	[src/sub1.c] Fixed underflow handling in case c small (can occur only
   5306 	with UBF).
   5307 
   5308 	[tests/tfma.c] Minor correction.
   5309 
   5310 	[tests/tfma.c] Changed a RND_LOOP to RND_LOOP_NO_RNDF as the behavior
   5311 	with RNDF changed after a bug fix.
   5312 
   5313 	[tests/tsub.c] Completed tests for UBF (currently fail).
   5314 
   5315 	[src/sub1.c] Bug fix for UBF and MPFR_RNDF.
   5316 
   5317 	[src/set_{si,ui}_2exp.c] Bug fix in MPFR_LONG_WITHIN_LIMB defined case:
   5318 	added early underflow/overflow checking to avoid integer overflow or
   5319 	errors due to special exponent values.
   5320 
   5321 	[tests/tset_si.c] Added tests of mpfr_set_si_2exp and mpfr_set_ui_2exp
   5322 	in precision 3 with integers from -31 to 31 and exponents MPFR_EXP_MIN,
   5323 	MPFR_EMIN_MIN-7 to MPFR_EMIN_MIN, MPFR_EMAX_MAX-7 to MPFR_EMAX_MAX,
   5324 	MPFR_EXP_MAX-7 to MPFR_EXP_MAX, showing bugs in these functions when
   5325 	MPFR_LONG_WITHIN_LIMB is defined.
   5326 
   5327 2020-03-24  Vincent Lefvre  <vincent (a] vinc17.net>
   5328 
   5329 	[tests/tsub.c] More tests on UBF. The results are not checked yet,
   5330 	but running the tests with UBsan could allow one to trigger bugs
   5331 	(such as the one fixed in r13806).
   5332 
   5333 	[src/sub1.c] If exp_b = MPFR_EXP_MIN, an integer overflow may occur in
   5334 	the "MAX (aq, bq) + 2 <= diff_exp" branch. This is possible only with
   5335 	UBF. Fixed this bug with an early underflow detection in the UBF case.
   5336 
   5337 	[tests/tfmma.c] Added extreme_underflow test: before the r13798 bug fix,
   5338 	this was triggering an integer overflow.
   5339 
   5340 	[tests/tsub.c] Corrected a function name.
   5341 
   5342 	[tests/tsub.c] More tests on UBF, in particular with an exponent change
   5343 	(including subnormal  normal and normal  overflow due to that).
   5344 
   5345 	[tests/tsub.c] Tests on UBF: underflow/overflow cases done.
   5346 
   5347 2020-03-23  Vincent Lefvre  <vincent (a] vinc17.net>
   5348 
   5349 	[tests/tsub.c] More tests on UBF.
   5350 
   5351 	[src/mpfr-impl.h] UBF: reordered macro definitions.
   5352 
   5353 	[src]
   5354 	  * mpfr-impl.h: define MPFR_UBF_GET_EXP macro.
   5355 	  * add1.c, sub1.c: use this macro.
   5356 
   5357 	[src/sub1.c] Detect an underflow case (before the main detection) to
   5358 	avoid a possible integer overflow with UBF.
   5359 
   5360 	[tests/tsub.c] Added comments.
   5361 
   5362 	[tests/tsub.c] First tests on UBF.
   5363 
   5364 	[src/agm.c] Avoid a potential integer overflow with huge precisions.
   5365 
   5366 2020-03-16  Vincent Lefvre  <vincent (a] vinc17.net>
   5367 
   5368 	[src/root.c] Removed useless cast in a comparison, as both operands are
   5369 	non-negative.
   5370 
   5371 	[src/rem1.c]
   5372 	  * Portability fix: when mpfr_exp_t <= long (which is the default),
   5373 	    an addition was done in unsigned integer arithmetic instead of
   5374 	    signed integer arithmetic, with a conversion back to a signed
   5375 	    type, i.e. with potentially implementation-defined behavior.
   5376 	    There could also be an integer overflow on huge-precision values
   5377 	    if mp_bitcnt_t > unsigned long.
   5378 	  * Updated a comment.
   5379 
   5380 	[src/pow.c]
   5381 	  * Portability fix: when mpfr_exp_t <= long (which is the default),
   5382 	    an addition with a negative result was done in unsigned integer
   5383 	    arithmetic instead of signed integer arithmetic, with a conversion
   5384 	    back to a signed type, i.e. with implementation-defined behavior.
   5385 	    There could also be an integer overflow on huge-precision values
   5386 	    if mp_bitcnt_t > unsigned long.
   5387 	  * Updated comments.
   5388 
   5389 	[src/cos.c] Updated a comment.
   5390 
   5391 	[src/cos.c] Updated a comment.
   5392 
   5393 	[src/const_log2.c] Corrected type for the return value of mpz_scan1.
   5394 
   5395 2020-03-13  Vincent Lefvre  <vincent (a] vinc17.net>
   5396 
   5397 	[tests/tests.c] Revert a change done in r13783 for function bad_cases():
   5398 	  no longer fail if a generated value does not correspond to a bad case.
   5399 	  But fail if the MPFR_CHECK_BADCASES environment variable is defined
   5400 	  and too few bad cases are generated (less than 90%).
   5401 	[doc/README.dev] Document MPFR_CHECK_BADCASES.
   5402 
   5403 	[tests] Update to test the ternary value in test5rm() when possible,
   5404 	and support the exact cases.
   5405 	  * tests.c:
   5406 	      - test5rm(): modified the prototype again and the behavior.
   5407 	        Now, either only one test is done and the ternary value is
   5408 	        not checked, or the test is done in the 5 rounding modes and
   5409 	        the ternary value is checked.
   5410 	      - data_check(): corresponding update; updated description.
   5411 	      - bad_cases(): test the exact cases too.
   5412 	  * tatanh.c: for the bad_cases() call, reduce emax to avoid errors in
   5413 	    the generation of bad cases due to the rounding of tanh(y) to 1,
   5414 	    which does not correspond to a bad case for atanh, but to an exact
   5415 	    case.
   5416 	  * tlog1p.c: for the bad_cases() call, reduce emax to avoid errors in
   5417 	    the generation of bad cases due to the rounding of expm1(y) to -1,
   5418 	    which does not correspond to a bad case for log1p, but to an exact
   5419 	    case.
   5420 	  * trec_sqrt.c: corrected the bad_cases() call to avoid negative
   5421 	    numbers.
   5422 	Note: the following tests
   5423 	  GMP_CHECK_RANDOMIZE=5 ./tacos
   5424 	  GMP_CHECK_RANDOMIZE=6 ./tatan
   5425 	  GMP_CHECK_RANDOMIZE=4 ./tcos
   5426 	currently fail, but because of a change in r13783 (see associated log
   5427 	for the reason). To be fixed later.
   5428 
   5429 	[tests/tests.c] Modified the prototype of test5rm() to support a
   5430 	parameter "exact". Therefore the parameter "test_one" is now a boolean
   5431 	(the value 2 is no longer supported, as redundant with "exact"), and
   5432 	about data_check() with rnd = '*', the loop is now done in test5rm(),
   5433 	i.e. test5rm() is called with test_one being false.
   5434 
   5435 2020-03-12  Vincent Lefvre  <vincent (a] vinc17.net>
   5436 
   5437 	[tests/tsqrt.c] For bad_cases(), use the same pos and psup parameters
   5438 	as in troot.c for "rootn[2]", allowing inexact cases.
   5439 
   5440 	[tests/tcbrt.c] For bad_cases(), use the same pos and psup parameters
   5441 	as in troot.c for "rootn[3]", allowing inexact cases.
   5442 
   5443 	[tests]
   5444 	  * tests.c, function bad_cases(): updated/added debug messages;
   5445 	    assume that the parameters are chosen in such a way that this
   5446 	    test always generates hard-to-round cases (including exact cases),
   5447 	    i.e. exit with an error if one does not get a bad case, otherwise
   5448 	    this can leave unexpected failures unnoticed (either due to a bug
   5449 	    in the MPFR library or due to poorly chosen parameters such as in
   5450 	    troot.c until now).
   5451 	    Note: ideally, this would require a proof, but it is better to get
   5452 	    (unlikely) spurious failures with a non-default GMP_CHECK_RANDOMIZE
   5453 	    value than missing important tests.
   5454 	  * troot.c, bad_cases() invocation:
   5455 	      - corrected the pos parameter: when n is even, it is useless to
   5456 	        generate a negative number as the function is not defined (the
   5457 	        inverse function generates a positive number, and the mismatch
   5458 	        now yields a failure due to the change in bad_cases); when n is
   5459 	        odd, generate as many negative numbers as positive ones.
   5460 	      - for n  5, reduce the psup parameter in order to also generate
   5461 	        inexact cases, instead of always exact cases.
   5462 
   5463 	[tests/tests.c] Added a TODO for bad_cases, as the exact cases are not
   5464 	tested yet. As a consequence, the bad_cases test added in tcbrt.c r13776
   5465 	is not really useful yet, as the cbrt bad cases are only exact cases.
   5466 
   5467 	[tests/tests.c]
   5468 	  * test5rm: removed additional useless tests added in r6037 in the
   5469 	    case test_one true and rnd = MPFR_RNDZ or MPFR_RNDA, since the
   5470 	    description was a bit incorrect and this was used only by
   5471 	      - data/digamma, where this yielded only duplicate tests (mode *);
   5472 	      - data/li2, where mode z is used on a few tests and could be
   5473 	        replaced by mode Z (i.e. test_one false) if need be;
   5474 	    updated description and added details.
   5475 	  * data_check: corrected/updated description.
   5476 
   5477 	[tests/tests.c] Minor change in an initialization.
   5478 
   5479 	[tests/tget_set_{d64,d128}.c] Added a FIXME and improved a message.
   5480 
   5481 	[acinclude.m4] Added a FIXME: in case of cross-compiling, the guess
   5482 	"DPD" can be wrong, e.g. for the build with MinGW under Linux. One
   5483 	does not get a failure just because of other issues in the code,
   5484 	forcing the portable implementation of the decimal functions.
   5485 
   5486 2020-03-11  Vincent Lefvre  <vincent (a] vinc17.net>
   5487 
   5488 	Added bad_cases tests for mpfr_cbrt.
   5489 
   5490 	[src/cbrt.c] Improved the algorithm in the case the precision of the
   5491 	input is larger than 3n, where n is the precision of the output, + 1
   5492 	if the rounding mode is MPFR_RNDN: instead of truncating the output,
   5493 	call mpz_root on the truncated input.
   5494 
   5495 	[tests/tcbrt.c] Test the ternary value on other exact cases.
   5496 
   5497 	[tests/tcbrt.c] Test the ternary value on special cases.
   5498 
   5499 	[src/cbrt.c] Description of the algorithm: improvement; corrected the
   5500 	end, which was incorrect and did not match the code (the comment was
   5501 	introduced in r2057 and was already incorrect in the round-down case;
   5502 	then the round-to-nearest case was improved in r2070, but the comment
   5503 	was not updated).
   5504

   5508 
   5509 	[src/cbrt.c] Description of the algorithm: corrected indentation;
   5510 	renamed variable r to t in order to avoid confusion with the code
   5511 	(where r has a different meaning).
   5512 
   5513 	[src/cbrt.c] Clarified a comment.
   5514 
   5515 	[src/cbrt.c] Resolved the second FIXME and simplified the code
   5516 	(basically by removing duplicate code).
   5517 
   5518 	[src/cbrt.c] Description of the algorithm:
   5519 	  * Since there was no upper bound on s, let's remove the upper bound
   5520 	    on m (this now matches the code).
   5521 	  * Replaced the FIXME by one due to the lack of upper bound on s.
   5522 
   5523 	[src/cbrt.c] Added another FIXME as the code does not match the
   5524 	algorithm described in a comment.
   5525 
   5526 	[src/cbrt.c] Improved a condition to avoid operations that correspond
   5527 	to a no-op.
   5528 
   5529 	[src/cbrt.c] Added an assertion.
   5530 
   5531 	[src/cbrt.c] Code cleanup and simplification. Added logging messages and
   5532 	a FIXME about a comment (coming from r2057 with its associated code).
   5533 
   5534 	[src/cbrt.c] Removed a useless cast on a comparison operand, since
   5535 	both operands are non-negative.
   5536 
   5537 	[src/atan.c] Added assertions.
   5538

   5558 	[src/sub1.c] cancel: also log its value; range checking/tracking.
   5559 
   5560 	[src/cmp2.c] Added a comment giving the range of the value returned
   5561 	in "cancel" and explaining why there is no integer overflow in the
   5562 	computation of this value.
   5563 
   5564 	[src/cmp2.c] Comment: some absolute values are not needed (again).
   5565 
   5566 	[src/cmp2.c] Minor correction for |EXP(b) - EXP(c)| >= MPFR_EXP_MAX.

   5570 2020-03-03  Vincent Lefvre  <vincent (a] vinc17.net>
   5571 
   5572 	[src/cmp2.c] Finished the review of mpfr_cmp2: simplified the code even
   5573 	more; corrected/updated comments (in the case high_dif = 0, one can have
   5574 	dif = 1 if c has entirely been taken into account, so that the comment
   5575 	"dif > 1 here" was incorrect; only dif >= 1 is needed anyway).
   5576 
   5577 	[src/cmp2.c] Changed high_dif to type int since it is manipulated like
   5578 	a boolean. Updated comments.

   6094 	[tests/tadd1sp.c] When testing mpfr_add, use a wrapper mpfr_add_cf

   6110 	(corresponding to the FIXME), yielding a failure with
   6111 	"--enable-assert=full".
   6112 	Note 1: The computed values are equal (with MPFR_RNDN), but one gets
   6113 	  Inexact sp = 0 | Inexact = -1
   6114 	  Flags sp = 10 | Flags = 10
   6115 	Note 2: The fact that the flags do not match the ternary value in the
   6116 	error message is due to a missing mpfr_clear_flags in the test.
   6117 
   6118 	[src/add1sp.c] mpfr_add1sp2n:
   6119 	  * Code refactoring, eliminating the unnecessary goto's.

   6121 	  * Improved code consistency.

   6156 	[tests/mpfr-test.h] At the end, with GCC, undef volatile if defined.
   6157 	Explanations:
   6158 	  With GCC, a macro "volatile" can be defined to test some special code
   6159 	  in mpfr-impl.h (code for compilers that define such a macro), but the
   6160 	  volatile keyword is necessary in some tests to avoid some GCC bugs.
   6161 	  Thus we need to undef this macro (if defined). We do that at the end,
   6162 	  so that mpfr-impl.h (included earlier) is not affected by this undef.
   6163 
   6164 	[tests/tget_set_d128.c] Updated a test with a non-canonical encoding:
   6165 	  * More meaningful name ("noncanonical" instead of "coverage").

   6173 
   6174 	[doc/mpfr.texi] Changed "decimal point" to "decimal-point character",
   6175 	which is the term used in the ISO C standard. This is better as this
   6176 	character is also used with non-decimal bases: "decimal-point" is
   6177 	just the name of this character (as initially defined for base 10)
   6178 	and does not imply a number written in decimal.
   6179 
   6180 	[doc/mpfr.texi] Compatibility With MPF: added an item on the difference

   6187 	[src/out_str.c] Fixed bug in mpfr_out_str: When the exponent of the
   6188 	converted value is 0, it was not output, contrary to what is described
   6189 	in the MPFR manual. Note that this does not change the value of the
   6190 	printed string, so that this has no effect on applications that just
   6191 	re-read the value (with MPFR or another code).
   6192 	This was regarded as a bug rather than an error in the documentation,
   6193 	thus the output now looks more similar to what printf with %e yields;
   6194 	the GMP function mpf_out_str also outputs the exponent 0.
   6195 	Short discussion:

   6217 
   6218 	[doc/mpfr.texi] About mpfr_get_str / mpfr_out_str:
   6219 	  * In the mpfr_get_str description, changed argument "b" to "base" for

   6223 	  * In the mpfr_out_str description, replaced the ambiguous and even
   6224 	    incorrect sentence "enough digits so that op can be read back
   6225 	    exactly" (issues with trailing zeros and with the directed rounding

   6240 
   6241 	[tests/tout_str.c] Added missing newline characters in the output
   6242 	after calls to mpfr_out_str.
   6243 
   6244 	[tests/tout_str.c] By default, output the results to a file instead of
   6245 	/dev/null (this was already done only if opening /dev/null failed), so
   6246 	that they can be checked later. Fixed 2 issues at the same time:
   6247 	  * Do not close stdout (when an argument was provided).
   6248 	  * Remove the file at the end.
   6249 
   6250 	[tests/tfpif.c] GNU coding style.
   6251 
   6252 	[tests/tfpif.c] Added a comment about the use of perror.
   6253 
   6254 	[tests/tfpif.c] Also check fclose failure when the file has been opened
   6255 	for writing (typically an error in case the buffer cannot be written to
   6256 	the file). Call perror after all fopen/src_fopen/fclose failures to get
   6257 	the reason of the failure.
   6258 
   6259 	[tests/tfpif.c] In case of failure of fopen or src_fopen, write the
   6260 	error message on stderr (as one should do for errors not directly
   6261 	related to the tests, such as memory allocation and I/O errors).
   6262 	Also improved the error messages and made them consistent.

   6273 
   6274 	For Makefile.am and each one in SUBDIRS, added the .POSIX target to
   6275 	select the POSIX behavior (since we do not require GNU "make").

   6277 
   6278 	[tools/get_patches.sh] Fixed change in r13543 (the contents of PATCHES

   6280 
   6281 	Fixed src/get_patches.c generation that was changed in r13542.
   6282 	  * src/Makefile.am, tools/get_patches.sh: since get_patches.sh is
   6283 	    no longer run from $(top_srcdir), the PATCHES absolute pathname
   6284 	    now needs to be passed in argument.
   6285 	  * src/Makefile.am: fixed the get_patches.c rule (the automatic
   6286 	    variable $< was used with the meaning "first prerequisite" of
   6287 	    GNU Make; an "exit 1" was missing, so that a failure did not
   6288 	    abort "make" immediately).
   6289 	  * tools/get_patches.sh: detect errors with "set -e".

   6291 2019-07-31  Vincent Lefvre  <vincent (a] vinc17.net>
   6292 
   6293 	[src/Makefile.am] Define get_patches.c as a built source to avoid a
   6294 	non-portable make rule ("/" character in target), causing an error
   6295 	in FreeBSD with its "make" command. This change should be OK as the
   6296 	get_patches.sh script that generates get_patches.c is very simple
   6297 	and portable. As a consequence, put get_patches.c in CLEANFILES.

   6301 	[Makefile.am] Fixed dist-hook for ck-mparam, which was run from a
   6302 	read-only directory with "make distcheck" while a temporary file
   6303 	is created in the current directory, yielding a failure (ck-mparam
   6304 	has been run in dist-hook since r12533 on 2018-04-03).
   6305 
   6306 	[tools/ck-mparam] Updated comment to warn that the source tree that is
   6307 	checked is the one that contains this script, not the one corresponding
   6308 	to the current working directory (the rule for the other scripts in the
   6309 	tools directory is currently different).
   6310 
   6311 	[tools/ck-mparam] This script can now be run from any directory (which
   6312 	must still be writable). This change has been done to be able to run
   6313 	it from the build directory, as if it is run via "make distcheck" and
   6314 	a dist-hook rule, then neither the top-level directory nor the tools
   6315 	directory is writable.

   6518 
   6519 	[src/vasprintf.c] Minor bug fix: when an integer is to be read for
   6520 	  the field width or precision, regard strings like "17*" as invalid
   6521 	  instead of regarding it as "*" (ignoring the integer that precedes,
   6522 	  except in case of overflow). In C's printf, such an invalid string
   6523 	  yields undefined behavior, but in MPFR, we normally print the
   6524 	  invalid format specifier as a literal string in such a case.
   6525 	  Bug detected with -Wimplicit-fallthrough from GCC 7+.
   6526 	[tests/tsprintf.c] Added non-regression test.

   6550 	  * Corrected FIXME by modifying the assertion. The failure could occur

   6552 	    when long = int and either intmax_t and long long are not available
   6553 	    or intmax_t = long = int), and only when INT_MIN is provided as a

   6556 	  * Added comments.
   6557 
   6558 	[src/vasprintf.c] Added a FIXME: tsprintf yields an assertion failure

   6561 2019-03-29  Vincent Lefvre  <vincent (a] vinc17.net>
   6562 
   6563 	Cleanup / fixes related to intmax_t, mpfr_intmax_t, etc.
   6564 
   6565 	The issues were:
   6566 	  * The build of the tests (make check) could fail with CFLAGS implying
   6567 	    "-std=c90 -Werror=format", i.e. if intmax_t was available but the
   6568 	    use of the "j" printf length modifier made the compilation fail
   6569 	    (its unconditional use was incorrect anyway).
   6570 	  * MPFR_INTMAX_MAX had definitions in both mpfr-impl.h & mpfr-intmax.h,
   6571 	    with inconsistent usage.
   6572 
   6573 	Detailed changes:
   6574 	  * acinclude.m4: removed the definition of MPFR_PRINTF_MAXLM, which
   6575 	    could be incorrect (large numbers were not tested to select its
   6576 	    value); in the MPFR_FUNC_GMP_PRINTF_SPEC macro, check sprintf()
   6577 	    in addition to gmp_sprintf() as it is now also used in the tests;
   6578 	    updated some comments and messages.
   6579 	  * src/mpfr-impl.h: removed the MPFR_*INTMAX* definitions; they had
   6580 	    been added due to
   6581 	      https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=582698
   6582 	    with -ansi -pedantic-errors, but this issue was fixed in GCC 4.8
   6583 	    (released 6 years ago), so that they are no longer needed.
   6584 	  * src/mpfr-intmax.h: completed the definitions; mpfr_intmax_t is now
   6585 	    the largest integer type available and fully working (in particular
   6586 	    with printf), thus it may be smaller than intmax_t.
   6587 	  * doc/README.dev: updated the description of mpfr_intmax_t, etc.
   6588 	  * tests/tversion.c: output sizeof(mpfr_intmax_t) too.
   6589 	  * Various .c files in src and tests related to (u)intmax_t: use
   6590 	    INTMAX_MAX instead of MPFR_INTMAX_MAX, etc. as Debian bug 582698
   6591 	    (mentioned above) no longer occurs and mpfr_intmax_t may be smaller
   6592 	    than intmax_t; use the "j" printf length modifier instead of
   6593 	    MPFR_PRINTF_MAXLM, and protect it with "#ifndef NPRINTF_J"
   6594 	    (only the tests are concerned, so that this is not an issue).

   6597 
   6598 	[src/urandomb.c] Removed the FIXME: this is a bug in GMP or in Clang's
   6599 	memory sanitizer.
   6600 
   6601 	[src/urandomb.c] Added a FIXME (use-of-uninitialized-value with
   6602 	Clang's memory sanitizer).
   6603 
   6604 2019-03-13  Vincent Lefvre  <vincent (a] vinc17.net>
   6605 
   6606 	[src/printf.c] Removed unused definitions.
   6607 
   6608 2019-03-01  Vincent Lefvre  <vincent (a] vinc17.net>
   6609 
   6610 	[doc/README.dev] Update about coverage:
   6611 	  * Mention not to enable optimizations.
   6612 	  * Replaced "-fprofile-arcs -ftest-coverage" by "--coverage", as
   6613 	    this is what is used by the tools/coverage script (note: this
   6614 	    is a synonym when compiling, but also allows the right options
   6615 	    to be used when linking, thus might be better in doubt).
   6616 
   6617 2019-02-04  Vincent Lefvre  <vincent (a] vinc17.net>
   6618 
   6619 	[tests] Use MPFR_DBL_* macros when necessary.
   6620 
   6621 	[tools/mpfrlint] For consistency, use "[ch]" instead of "{c,h}".
   6622 
   6623 	[tools/mpfrlint] Detect use of DBL_* macros instead of MPFR_DBL_* ones.
   6624 
   6625 	[tools/mpfrlint] Improved message about division by zero.
   6626 
   6627 	[doc/README.dev] Improved description of MPFR_ERRDIVZERO.
   6628 	[tools/mpfrlint] Added a comment about division by zero.
   6629 
   6630 	[tools/mpfrlint] Check that native FP division by zero is not used.
   6631 
   6632 2019-01-31  Vincent Lefvre  <vincent (a] vinc17.net>
   6633 
   6634 	[src/Makefile.am] In check-exported-symbols, replaced grep by $(GREP)
   6635 	as usual and like in check-gmp-symbols.
   6636 
   6637 2019-01-30  Vincent Lefvre  <vincent (a] vinc17.net>
   6638 
   6639 	[configure.ac] Updated comment about default options in CFLAGS for GCC.
   6640 
   6641 	Update about CC / CFLAGS settings from GMP (__GMP_CC / __GMP_CFLAGS).
   6642 	  * configure.ac: remove -pedantic unconditionally; since r7044, it was
   6643 	    removed only when logging was enabled, as at that time only logging
   6644 	    was using C extensions.
   6645 	  * NEWS: added a line about this change.
   6646 	  * INSTALL: updated the note about CC / CFLAGS, removing the obsolete
   6647 	    reference to GMP 4.3.0 at the same time.
   6648 
   6649 2019-01-28  Vincent Lefvre  <vincent (a] vinc17.net>
   6650 
   6651 	[tools/announce-text] Corrected subject for Release Candidate > 1.
   6652 
   6653 2019-01-25  Vincent Lefvre  <vincent (a] vinc17.net>
   6654 
   6655 	ChangeLog update with "LC_ALL=en_US.UTF8 TZ=UTC svn log -rHEAD:0 -v".
   6656 
   6657 	[NEWS] Update about shared caches.
   6658 
   6659 	[NEWS] Added: "Shared caches: cleanup."
   6660 
   6661 	[src/mpfr-thread.h] Fixed the lock macros:
   6662 	  * in case of failure, one must abort, otherwise this would generally
   6663 	    be undefined behavior;
   6664 	  * added missing "do {} while (0)" (currently not mandatory).
   6665 
   6666 	[src/mpfr-impl.h] Updated a comment about MPFR_DECL_INIT_CACHE and
   6667 	the shared cache.
   6668 
   6669 	[acinclude.m4] Avoid a warning with the pthread_rwlock_t test,
   6670 	as it is an error with -Werror.
   6671 
   6672 	[acinclude.m4] Fixed another C++ compatibility issue detected by
   6673 	the -Werror=c++-compat GCC option (it led the "long double" format
   6674 	to be unknown).
   6675 
   6676 2019-01-24  Vincent Lefvre  <vincent (a] vinc17.net>
   6677 
   6678 	[tests/trint.c] Fixed C++ compatibility issue (arithmetic on enum)
   6679 	detected by the -Werror=c++-compat GCC option.
   6680 
   6681 2019-01-23  Vincent Lefvre  <vincent (a] vinc17.net>
   6682 
   6683 	[configure.ac] By default (i.e. if CFLAGS is not already set), if
   6684 	the compiler is GCC not in C++ mode, add the -Wc++-compat warning
   6685 	since we expect the code to compile with a C++ compiler.
   6686 
   6687 2019-01-13  Vincent Lefvre  <vincent (a] vinc17.net>
   6688 
   6689 	[tests/tcheck.c] Corrected meaningless error message.
   6690 
   6691 	[doc/mpfr.texi] Minor correction for non-tex versions.
   6692 	Thanks to Trevor Spiteri for the bug report.
   6693 
   6694 2019-01-09  Vincent Lefvre  <vincent (a] vinc17.net>
   6695 
   6696 	Moved the compatibility test of the configure options even earlier, from
   6697 	acinclude.m4 to configure.ac, just after the code that defines them.
   6698 	Also added an associated AC_MSG_CHECKING message for better clarity.
   6699 
   6700 	[acinclude.m4] Simplified a message.
   6701 
   6702 	[tests/tversion.c] When the shared cache is enabled, also output the
   6703 	lock method (this information has been lost in r13032).
   6704 
   6705 	[acinclude.m4] When checking support for POSIX threads (pthread), also
   6706 	check that pthread_rwlock_t is supported, as it is needed by MPFR and
   6707 	conditionally defined in glibc's bits/pthreadtypes.h (via <pthread.h>).
   6708 
   6709 	Cleaned up configure code related to threading and the shared cache.
   6710 	  * acinclude.m4:
   6711 	      - detect incompatibilities between configure options at the
   6712 	        beginning of MPFR_CONFIGS, forcing enable_thread_safe to
   6713 	        "no" or "yes" when necessary, so that the subsequent code
   6714 	        can rely on that;
   6715 	      - check ISO C11 thread support and/or POSIX thread support
   6716 	        only when necessary;
   6717 	      - handle --enable-shared-cache early in MPFR_CONFIGS, because
   6718 	        the use of POSIX threads (pthread) may need to change CC,
   6719 	        CFLAGS, and LIBS (thus affecting other tests);
   6720 	      - test $enable_shared_cache instead of $mpfr_want_shared_cache;
   6721 	      - removed the now useless MPFR_CHECK_SHARED_CACHE function.
   6722 	  * configure.ac: no longer set the mpfr_want_shared_cache variable,
   6723 	    as enable_shared_cache (now used) already has the same usage.
   6724 	Note: currently,
   6725 	  ./configure --enable-shared-cache CFLAGS="-std=c99"
   6726 	still succeeds and still makes the compilation fail. This seems to
   6727 	be due to a limitation of AX_PTHREAD, which just tests linking, not
   6728 	compilation.
   6729 
   6730 	[acinclude.m4] In MPFR_CHECK_SHARED_CACHE (used when the shared cache
   6731 	was requested), also set CC="$PTHREAD_CC" as documented by ax_pthread
   6732 	(autoconf-archive). This is not guaranteed to work, but according to
   6733 	the ax_pthread.m4 source, in the cases where "$PTHREAD_CC" != "$CC",
   6734 	not setting it will probably not work either.
   6735 
   6736 	[src/mpfr-impl.h] Added a comment about the cache-related types, which
   6737 	depend on the locking methods.
   6738 
   6739 2019-01-08  Vincent Lefvre  <vincent (a] vinc17.net>
   6740 
   6741 	[tests/tstrtofr.c] Updated comment about GCC bug 86554: now fixed in
   6742 	the GCC trunk.
   6743 
   6744 2019-01-07  Vincent Lefvre  <vincent (a] vinc17.net>
   6745 
   6746 	[tests/Makefile.am] Replaced "env -u DISPLAY" by "env DISPLAY=''" as
   6747 	the -u option is not supported by NetBSD.
   6748 
   6749 	Updated files:
   6750 	  * COPYING from https://www.gnu.org/licenses/gpl-3.0.txt
   6751 	  * COPYING.LESSER from https://www.gnu.org/licenses/lgpl-3.0.txt
   6752 	These are URL updates and cosmetic changes.
   6753 
   6754 	ChangeLog update with "LC_ALL=en_US.UTF8 TZ=UTC0 svn log -rHEAD:0 -v".
   6755 	Note: For r5400, this changes an incorrect update done via r13372 back
   6756 	to the old log message, as the URL in this log message here describes
   6757 	a change in one of the files.
   6758 
   6759 	[doc/README.dev] Updated some URL's (http  https).
   6760 
   6761 	[doc/texinfo.tex] Update to 2018-02-12.17 with "autoreconf -i -f".
   6762 
   6763 	Updated the www.gnu.org URL's (http  https) on all the files with:
   6764 	  perl -pi -e 's,http://www.gnu.org/,https://www.gnu.org/,g' **/*(.)
   6765 	under zsh.
   6766 
   6767 	[tests/tstrtofr.c] Updated comment about GCC bug 86554: the MPFR build
   6768 	is still affected with the latest gcc-snapshot version (20190102-1)
   6769 	when using --with-gmp-build=... together with --enable-assert.
   6770 
   6771 2019-01-04  Vincent Lefvre  <vincent (a] vinc17.net>
   6772 
   6773 	[tests/tstrtofr.c] Added a comment about GCC bug 86554: the MPFR build
   6774 	seems no longer affected by recent gcc-snapshot versions.
   6775 
   6776 2019-01-01  Vincent Lefvre  <vincent (a] vinc17.net>
   6777 
   6778 	[doc/mpfr.texi] Updated the month.
   6779 
   6780 	Copyright notice update: added 2019 with
   6781 	  perl -pi -e 's/ (\d{4}-)?(2018)(?= Free Software)/
   6782 	               " ".($1||"$2-").($2+1)/e' **/*(^/)
   6783 	under zsh. Removed 2018 from the example in the doc/README.dev file.
   6784 
   6785 2018-12-31  Vincent Lefvre  <vincent (a] vinc17.net>
   6786 
   6787 	[tests/tfmma.c] Added double_rounding test to trigger errors before
   6788 	the fix in mpfr_set_1_2 (set.c r13347).
   6789 
   6790 	[src/set.c] In mpfr_set_1_2, evaluate MPFR_PREC(s) just once.
   6791 
   6792 	[src/set.c] Clarified the mpfr_set_1_2 description.
   6793 
   6794 	[src/set.c] For mpfr_set_1_2, corrected the comments and simplified the
   6795 	generic algorithm (there is no need to distinguish the rounding modes,
   6796 	except for the double-rounding test, and this simplification avoids the
   6797 	non-portable inex | inex2).
   6798 
   6799 2018-12-20  Vincent Lefvre  <vincent (a] vinc17.net>
   6800 
   6801 	[doc/mini-gmp] Removed "#define GMP_LIMB_BITS 8": it is not used by
   6802 	mini-gmp.h and yields a failure when building mini-gmp.c (which has
   6803 	its own definition of GMP_LIMB_BITS, equivalent but not identical).
   6804 
   6805 	[configure.ac] Support mini-gmp with reduced limb size, in the case
   6806 	GMP_NUMB_BITS is not defined: guess GMP_NUMB_BITS from the size of
   6807 	mp_limb_t instead of the size of unsigned long.
   6808 
   6809 	[doc/mini-gmp] Correction to avoid a "conflicting types for 'mp_limb_t'"
   6810 	error.
   6811 
   6812 2018-12-14  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   6813 
   6814 	[doc/mini-gmp] added note about using mini-gmp (development version) with
   6815 		       reduced limb size
   6816 
   6817 	[src/set.c] fixed double-rounding bug in mpfr_set_1_2
   6818 	[tests/tset.c] added corresponding tests
   6819 
   6820 	[tests/tset.c] added a test of test_set_1_2(), which currently fails
   6821 
   6822 	[tests/tcan_round.c] disabled tests that don't agree with mpfr_can_round documentation
   6823 
   6824 2018-12-13  Vincent Lefvre  <vincent (a] vinc17.net>
   6825 
   6826 	[tests/tsprintf.c] Updated a comment about ISO C vs POSIX for snprintf.
   6827 
   6828 	[tests/tsprintf.c] Updated a comment about ISO C vs POSIX for snprintf.
   6829 
   6830 	[TODO] Added item: new functions mpfr_cmp_uj and mpfr_cmp_sj.
   6831 
   6832 	[TODO] Removed obsolete "check again coverage" from 2007.
   6833 
   6834 2018-12-13  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   6835 
   6836 	[src/sqr.c] fixed same issue as in r13338 and r13339
   6837 
   6838 	[src/mul.c] fixed bug in mpfr_mul() when sizeof(mp_limb_t) < sizeof(mpfr_exp_t)
   6839 		    (same issue as in r13338)
   6840 
   6841 2018-12-12  Vincent Lefvre  <vincent (a] vinc17.net>
   6842 
   6843 	[src/mul.c] For MPFR_WANT_ASSERT >= 2: minor changes in the code;
   6844 	corrected a comment (even with mp_limb_t >= mpfr_exp_t, there was an
   6845 	issue: the expression b1 - 1 + cc was computed in unsigned arithmetic,
   6846 	then converted to mpfr_exp_t, with an implementation-defined result
   6847 	when -1 was expected, i.e. with b1 = cc = 0).
   6848 
   6849 	[src/mul.c] Corrected a typo in a comment.
   6850 
   6851 	[src/mul.c] Fixed error message with MPFR_WANT_ASSERT >= 2.
   6852 
   6853 2018-12-11  Vincent Lefvre  <vincent (a] vinc17.net>
   6854 
   6855 	[src/mpfr-gmp.h] For count_leading_zeros (MPFR_LONG_WITHIN_LIMB
   6856 	not defined), no longer assume GMP_NUMB_BITS <= 32.
   6857 
   6858 	[src/mpfr-gmp.h] Fixed count_leading_zeros (avoid undefined behavior
   6859 	on shift counts, which must be nonnegative and smaller than the width
   6860 	of the type of the shifted value).
   6861 
   6862 2018-12-11  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   6863 
   6864 	[src/mul.c] fixed reference routine mpfr_mul3() when sizeof(limb) < sizeof(exp)
   6865 
   6866 	[src/mpfr-gmp.h] fixed count_leading_zeros for mini-gmp with 32-bit limb
   6867 
   6868 2018-12-10  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   6869 
   6870 	[doc/mini-gmp] added remark about random functions
   6871 
   6872 	[tests/tdiv.c] fixed test_20151023 (was giving an error with micro-gmp-8
   6873 	and GMP_CHECK_RANDOMIZE=1544431052619574)
   6874 
   6875 2018-12-10  Vincent Lefvre  <vincent (a] vinc17.net>
   6876 
   6877 	[tools/mpfrlint] Added a test for some avoidable use of gmp_printf.
   6878 
   6879 2018-12-07  Vincent Lefvre  <vincent (a] vinc17.net>
   6880 
   6881 	[tests]
   6882 	  * mpfr-test.h, tests.c: added n_trace function to output a mpn.
   6883 	  * tcan_round.c: use n_trace instead of gmp_printf ("%NX\n",...),
   6884 	    which is not available with mini-gmp.
   6885 
   6886 2018-12-06  Vincent Lefvre  <vincent (a] vinc17.net>
   6887 
   6888 	[tests/tcan_round.c] Corrected all the error messages for mini-gmp.

   6893 
   6894 	[tests/tpow_z.c] Another fix and minor improvements.
   6895 
   6896 	[tests/tpow_z.c] Fixed a test (midpoint case) that was failing
   6897 	with micro-gmp-8 and GMP_CHECK_RANDOMIZE=1544033327230569.
   6898 
   6899 	[tests/tpow_z.c] Fixed a test for MPFR_RNDF: do not check the ternary
   6900 	value (a failure was occurring with --with-mini-gmp=.../micro-gmp/8
   6901 	and GMP_CHECK_RANDOMIZE=1544025040809270).
   6902 
   6903 	[tests/tpow_z.c] Improved error message.
   6904 
   6905 	[src/mpfr-mini-gmp.c] Added missing "void" in function prototype.
   6906 
   6907 	[configure.ac] When building against mini-gmp, check the availability of
   6908 	lrand48, in particular because it is not part of the ISO C standard.
   6909 
   6910 2018-12-05  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   6911 
   6912 	[src/mpfr-mini-gmp.c] put back unconditional assert from r13316 (removed by error)
   6913 
   6914 	[src/mpfr-mini-gmp.c] improved random_limb (the low bits of lrand48 are bad)
   6915 			      and fixed gmp_urandomm_ui
   6916 
   6917 2018-12-05  Vincent Lefvre  <vincent (a] vinc17.net>
   6918 
   6919 	[src/mpfr-mini-gmp.c] gmp_urandomm_ui: added a MPFR_ASSERTN
   6920 	unconditionally, as n == 0 is always forbidden.
   6921 
   6922 2018-12-05  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   6923 
   6924 	[src/mpfr-mini-gmp.c] the static assert introduced in r13313 makes the
   6925 			      compilation fail for 8-bit limbs, while the code
   6926 			      was valid for n <= 256 in that case
   6927

   6929 
   6930 	[src/mpfr-mini-gmp.c] Fixed types.
   6931

   6943 2018-11-29  Vincent Lefvre  <vincent (a] vinc17.net>
   6944 
   6945 	[tests/Makefile.am] About r13308, added references to the bugs.
   6946 
   6947 	[tests/Makefile.am] Unset DISPLAY as it is not needed and it can yield
   6948 	error messages when running the tests with LOG_COMPILER=wine (for builds
   6949 	with MinGW).
   6950 
   6951 	[tests/tversion.c] Updated a comment about an output issue with MinGW,
   6952 	with the test run under Wine (which is really the cause of the issue).
   6953 
   6954 2018-11-28  Vincent Lefvre  <vincent (a] vinc17.net>
   6955 
   6956 	[tests/tstrtofr.c] In case of failure of some particular test, output
   6957 	the probable cause of this failure (GCC bug 86554) with a workaround.
   6958 
   6959 2018-11-27  Vincent Lefvre  <vincent (a] vinc17.net>
   6960 
   6961 	[tests/tversion.c] Updated a comment about a printf issue with MinGW.
   6962 
   6963 	[src/strtofr.c] Added a FIXME about the error analysis (info that was
   6964 	part of the FIXME resolved in r13303 and inadvertently dropped).
   6965 
   6966 	[src/strtofr.c] Resolved a FIXME; tstrtofr no longer fails due to
   6967 	bug20181127 with 8-bit limbs (micro-gmp/8).
   6968 
   6969 	[tests/tstrtofr.c] Added bug20181127 (test found with random_tests),
   6970 	which fails with 8-bit limbs (micro-gmp/8).
   6971 
   6972 	[src/mpfr-impl.h] Added a comment with a warning concerning the
   6973 	  meaning of MPFR_EXP_FSPEC.
   6974 	[tests/tstrtofr.c] Fixed a MPFR_EXP_FSPEC related bug in a test
   6975 	  for _MPFR_EXP_FORMAT <= 2, e.g. with -D_MPFR_PREC_FORMAT=2.
   6976 
   6977 	[tests/tdiv.c] Fixed bad format string for an error message, detected
   6978 	with -D_MPFR_PREC_FORMAT=2 (using -Werror...).
   6979 
   6980 2018-11-26  Vincent Lefvre  <vincent (a] vinc17.net>
   6981 
   6982 	[tests] Moved bug20180908() from tget_str.c to tset_str.c since it tests
   6983 	mpfr_set_str() only. This test was introduced in r13164.
   6984 
   6985 2018-11-23  Vincent Lefvre  <vincent (a] vinc17.net>
   6986 
   6987 	[TODO] + More UBF functions.
   6988 
   6989 	[doc/mpfr.texi] Updated the month.
   6990 
   6991 	[src/strtofr.c] Changed some unsigned long to unsigned int.
   6992 
   6993 	[src/strtofr.c] Some cleanup in parsed_string_to_mpfr. Avoid a potential
   6994 	integer overflow in very high precision if mp_size_t < mpfr_prec_t.
   6995 
   6996 2018-11-22  Vincent Lefvre  <vincent (a] vinc17.net>
   6997 
   6998 	[src/strtofr.c] Updated FIXME, due to new tests added to
   6999 	tests/tstrtofr.c in r13278-13279,13286-13288.
   7000 
   7001 	[src/nbits_ulong.c] Added missing initialization from r13269
   7002 	when MPFR_LONG_WITHIN_LIMB is not defined.
   7003 
   7004 	[tests/tstrtofr.c] Resolved the FIXME and fixed the issue related to
   7005 	the old mpfr_get_str description (see r13283).
   7006 	Note: with the later fix r13289, a test still fails with 8-bit limbs
   7007 	(incorrect exponent, possibly corresponding to the FIXME just before
   7008 	"exp = GMP_NUMB_BITS - count;" in src/strtofr.c).
   7009 
   7010 	[tests/tstrtofr.c] Added comments, including a FIXME.
   7011 
   7012 	[tests/tstrtofr.c] Resolved the FIXME for the random tests, and
   7013 	increased the number of tests to trigger a failure.
   7014 
   7015 	MPFR manual: corrected/completed the mpfr_get_str description in order
   7016 	to follow the historical behavior and GMP's mpf_get_str function.
   7017 	(Discussion in the Trier meeting.)
   7018 
   7019 	[src/get_str.c] Code style.
   7020 
   7021 	[doc/README.dev] Update about issues with mixing signed/unsigned types.
   7022 
   7023 	[doc/README.dev] Added a note about the disallowed conversions between
   7024 	function pointers and other kinds of pointers (including to void *).
   7025 
   7026 2018-11-20  Vincent Lefvre  <vincent (a] vinc17.net>
   7027 
   7028 	[tests/tstrtofr.c] Added a FIXME, which explains the current failure.
   7029 	But there is currently an inconsistency in mpfr_get_str, whose digits
   7030 	are not specified:
   7031 	  https://sympa.inria.fr/sympa/arc/mpfr/2018-11/msg00021.html
   7032 
   7033 	[tests/tstrtofr.c] Added random tests, which currently fail.
   7034 
   7035 2018-11-19  Vincent Lefvre  <vincent (a] vinc17.net>
   7036 
   7037 	[src/round_prec.c] mpfr_can_round_raw: improved the code structure about
   7038 	rnd1 and rnd2, making clear that they are not changed several times;
   7039 	avoid the use of cc with 2 different meanings in the same code path.
   7040 
   7041 2018-11-17  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   7042 
   7043 	[src/round_prec.c] fixed bug in mpfr_can_round when rnd2=RNDF, rnd1 is a
   7044 			   directed rounding, and the input is exact
   7045 
   7046 2018-11-16  Vincent Lefvre  <vincent (a] vinc17.net>
   7047 
   7048 	[src/strtofr.c] parsed_string_to_mpfr: updated a FIXME comment.
   7049 	In short, the current tstrtofr.c tests seem to always be hard-to-round
   7050 	cases. The consequence is that some parts of the code are run, but not
   7051 	completely tested, because for these cases, some intermediate results,
   7052 	potentially incorrect, are thrown out due to the next Ziv iteration!
   7053 
   7054 	[src/strtofr.c] parsed_string_to_mpfr: minor changes.
   7055 
   7056 	[src/strtofr.c] parsed_string_to_mpfr: added log messages.
   7057 
   7058 	[src/strtofr.c] Minor change to use MPFR_ASSERTD.
   7059 
   7060 	[src/{int_ceil_log2.c,mpfr-impl.h}] Consistent postcondition for
   7061 	MPFR_INT_CEIL_LOG2 and __gmpfr_int_ceil_log2 (result >= 0).
   7062 
   7063 	[src/nbits_ulong.c] Code refactoring. Added {pre,post}condition.
   7064 
   7065 	[src/strtofr.c] parsed_string_to_mpfr: removed an incorrect cast.
   7066 
   7067 	[src/strtofr.c] parsed_string_to_mpfr: updated a FIXME comment (again,
   7068 	another issue).
   7069 
   7070 	[src/strtofr.c] parsed_string_to_mpfr: updated a FIXME comment (there
   7071 	is another issue to solve first).
   7072 
   7073 	Removed trailing whitespace.
   7074 
   7075 	[src/strtofr.c] parsed_string_to_mpfr: updated a comment (useless code
   7076 	in this function or incomplete tests).
   7077 
   7078 	Avoid GCC's -Wcast-align warnings with 8-bit limbs (a correct alignment
   7079 	is ensured by the code itself, and GCC cannot check just from a cast).
   7080 
   7081 	[src/strtofr.c] parsed_string_to_mpfr: updated comments.
   7082 
   7083 2018-11-15  Vincent Lefvre  <vincent (a] vinc17.net>
   7084 
   7085 	[src/strtofr.c] parsed_string_to_mpfr: more code review, with minor
   7086 	changes and corrections + a FIXME.
   7087 
   7088 	[src/strtofr.c] Typo.
   7089 
   7090 	[src/strtofr.c] Fixed an allocation bug for GMP_NUMB_BITS = 8.
   7091 
   7092 	[src/strtofr.c] Updated a comment: the issue with mpn_set_str found
   7093 	in 2013-12 (see r8722) was actually an error in the GMP manual.
   7094 
   7095 	[src/strtofr.c] parsed_string_to_mpfr: improved an assertion; comments.
   7096 
   7097 2018-11-15  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   7098 
   7099 	[tests/tcan_round.c] fixed some TODOs, which exposes a bug
   7100 
   7101 2018-11-15  Vincent Lefvre  <vincent (a] vinc17.net>
   7102 
   7103 	[src/strtofr.c] Near the beginning of parsed_string_to_mpfr: corrected
   7104 	comments; added an assertion; minor change of a test.
   7105 
   7106 2018-11-10  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   7107 
   7108 	[src/mulders.c] fixed issue with --enable-gmp-internals
   7109 	[tune/tuneup.c] likewise
   7110 	(see https://sympa.inria.fr/sympa/arc/mpfr/2018-11/msg00015.html)
   7111 
   7112 2018-10-18  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   7113 
   7114 	[src/mpfr-longlong.h] applied patch from https://sympa.inria.fr/sympa/arc/mpfr/2018-10/msg00010.html
   7115 
   7116 2018-10-07  Vincent Lefvre  <vincent (a] vinc17.net>
   7117 
   7118 	[codespell.ignore] Also ignore "ue" (codespell 1.14).
   7119 
   7120 2018-10-01  Vincent Lefvre  <vincent (a] vinc17.net>
   7121 
   7122 	[configure.ac,src/Makefile.am] About the --with-mini-gmp support, since
   7123 	there are some advantages with the new code, one will probably not go
   7124 	back. Thus removed the references to the Automake 1.15 bug and to the
   7125 	old code. Also removed the mini_gmp_path=. workaround needed with the
   7126 	old code (even with Automake 1.16), which had been added in r13217.
   7127 	Also slightly improved the setup for mini-gmp.
   7128 
   7129 	[doc/with-mini-gmp.patch] Updated comment.
   7130 
   7131 	[configure.ac,src/Makefile.am] Avoid a "make" failure due to a bug in
   7132 	Automake 1.15 automatic dependency tracking: instead of using mini-gmp
   7133 	directly in an external directory with a $(mini_gmp_path) variable in
   7134 	src/Makefile.am, make the configure script add symbolic links to the
   7135 	mini-gmp sources in the build directory, and use these symbolic links
   7136 	for the MPFR build (as if they were plain files).
   7137 	Tested under various conditions: static and shared; separate source and
   7138 	build directories; changing the mini-gmp version without "make clean".
   7139 
   7140 2018-09-28  Vincent Lefvre  <vincent (a] vinc17.net>
   7141 
   7142 	Added doc/with-mini-gmp.patch file (for the developers):
   7143 	Modifications to configure.ac and src/Makefile.am that had been done
   7144 	for --with-mini-gmp support. This is kept for the reference, as changes
   7145 	may be needed as a workaround to a bug fixed in GNU Automake 1.16, and
   7146 	other future changes might break things (to remember what was working
   7147 	at this time).
   7148 
   7149 2018-09-20  Vincent Lefvre  <vincent (a] vinc17.net>
   7150 
   7151 	[doc/mini-gmp] Update.
   7152 
   7153 2018-09-19  Vincent Lefvre  <vincent (a] vinc17.net>
   7154 
   7155 	[Makefile.am] Distribute the doc/mini-gmp file.
   7156 	[configure.ac] For --with-mini-gmp, say:
   7157 	  "(experimental, please read doc/mini-gmp file)"
   7158 
   7159 	[src/Makefile.am] Added nodist_ for mini-gmp.{c,h} so that these files
   7160 	(not part of MPFR) are not put in the tarballs by "make dist".
   7161 
   7162 	Removed --enable-mini-gmp configure option.
   7163 	  * NEWS: say that it is replaced by --with-mini-gmp.
   7164 	  * configure.ac: --enable-mini-gmp removed.
   7165 	  * doc/mini-gmp: update.
   7166 
   7167 	[src/mpfr-mini-gmp.c] Missing #else (from r13156).
   7168 
   7169 	[configure.ac] When using --with-mini-gmp, define GMP_NUMB_BITS if this
   7170 	macro is not already defined in mini-gmp.h (this is done a bit like
   7171 	with --enable-mini-gmp, but the handling in this option is buggy as
   7172 	GMP_NUMB_BITS is defined with AC_DEFINE_UNQUOTED unconditionally,
   7173 	though is most cases the contents of the macros are the same).
   7174 
   7175 	[configure.ac] Do not split "Setup GMP detection". When building
   7176 	MPFR against mini-gmp, do not run any "Setup GMP detection" test
   7177 	(in particular, no longer check gmp.h, as it is useless).
   7178 
   7179 	[src/mpfr-mini-gmp.h] Removed incorrect GMP_NUMB_BITS macro definition,
   7180 	and this macro needs to be usable in preprocessor tests, and sizeof and
   7181 	types are not available at this level. GMP_NUMB_BITS must be defined by
   7182 	mini-gmp.h, by the configure script, or by the user.
   7183 
   7184 	[tools/mpfrlint] Update due to r13221.
   7185 
   7186 2018-09-18  Vincent Lefvre  <vincent (a] vinc17.net>
   7187 
   7188 	[tests/Makefile.am] Run tversion at the beginning of the tests,
   7189 	then show its output and svnversion's output too.
   7190 
   7191 	[src/mpfr-mini-gmp.h] Added a FIXME (failure with a mini-gmp that
   7192 	does not define GMP_NUMB_BITS, such as the official one).
   7193 
   7194 	[tests/random2.c] Avoid undefined behavior on shift count.
   7195 
   7196 	[src/mpfr-impl.h] Fixed MPFR_LIMB_MASK() macro.
   7197 
   7198 	[configure.ac] Avoid a configure failure with automatic dependency
   7199 	tracking when --with-mini-gmp is not used (bug in Automake?).
   7200 
   7201 	[NEWS] + Mini-gmp support via the --with-mini-gmp configure option.
   7202 
   7203 2018-09-17  Vincent Lefvre  <vincent (a] vinc17.net>
   7204 
   7205 	Merged the with-mini-gmp branch into the trunk: new --with-mini-gmp
   7206 	configure option to build MPFR against mini-gmp (instead of GMP).
   7207 
   7208 	[doc/mini-gmp] Update.
   7209 
   7210 	Merged the latest changes from the trunk.
   7211 
   7212 	[src/mul_ui.c] Better code organization (with the MPFR_RET at the right
   7213 	place). Corrected indentation after #else.
   7214 
   7215 2018-09-17  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   7219 
   7220 2018-09-17  Vincent Lefvre  <vincent (a] vinc17.net>
   7221 
   7222 	[src/Makefile.am] Update for mini-gmp (install mini-gmp.h).

   7232 	[tests/random2.c] Improved code by using MPFR_LIMB_* macros.
   7233 
   7234 	[src/mpfr-impl.h] Improved MPFR_LIMB_* macros for mp_limb_t < int
   7235 	(e.g. 16-bit or 8-bit limb), as in such a case, integer promotion
   7236 	transforms mp_limb_t to int.

   7310 2018-09-12  Vincent Lefvre  <vincent (a] vinc17.net>
   7311 
   7312 	[src/mpfr-mini-gmp.h] Removed #include lines as mpfr-mini-gmp.h is
   7313 	included only in mpfr-impl.h, which already does these #include's.
   7314 
   7315 	[src/mpfr-impl.h] Check that MPFR_HAVE_GMP_IMPL and MPFR_USE_MINI_GMP
   7316 	are not both defined.
   7317 
   7318 	[src/mpfr-mini-gmp.c] Removed #include "mpfr-mini-gmp.h" as this include
   7319 	is already done in mpfr-impl.h (in both cases, when MPFR_USE_MINI_GMP is
   7320 	defined).
   7321 
   7322 	[src/rec_sqrt.c] Replaced "if (GMP_NUMB_BITS >= 16)" by a preprocessor
   7323 	test "#if GMP_NUMB_BITS >= 16" like earlier. Use static assertions.

   7325 	[src/rec_sqrt.c] Fixed types for 8-bit limb. Removed useless casts.
   7326 
   7327 	[src/rec_sqrt.c] Fixed a type from r13172 (int was obviously too short
   7328 	and was yielding a segmentation fault).

   7386 	places to avoid unwanted line breaking.
   7387 
   7388 	[doc/mpfr.texi] mpfr_rootn_ui, mpfr_root: changed k to n in order to
   7389 	match IEEE 754-2008. Also improved the description of mpfr_rootn_ui,
   7390 	mentioning the P754/D2.41 draft of the next IEEE 754 standard because
   7391 	IEEE 754-2008 is incomplete.

   7405 
   7406 	Removed trailing whitespace.
   7407 
   7408 	[src/get_ld.c] Removed incorrect and useless assertions (manl
   7409 	has exactly 32 bits, thus a shift count of 32 bits is invalid,
   7410 	but also useless).
   7411 
   7412 2018-09-05  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   7417 
   7418 	[src/set_d64.c] 2 fixes concerning rp[]:
   7419 	  * If GMP_NUMB_BITS >= 64, there is a shift of 32 bits, thus one
   7420 	    uses mp_limb_t (> 32 bits) instead of unsigned int.
   7421 	  * Otherwise use unsigned long as an unsigned int might be on 16 bits.
   7422 
   7423 	[src/mpfr-impl.h] Indentation.
   7424 
   7425 	[src] Moved mpfr_nbits_ulong to its own file "nbits_ulong.c".
   7426 
   7427 	[src/pow_si.c] MPFR_NEED_LONGLONG_H is still needed.

   7442 
   7443 	[src/get_ld.c] In the case GMP_NUMB_BITS == 16, cast to unsigned long
   7444 	instead of unsigned int since shift counts can be up to 16 and an int
   7445 	might be on 16 bits only.
   7446 
   7447 2018-09-05  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   7485 
   7486 	[src/sqrt_ui.c] Moved MPFR_SAVE_EXPO_FREE after mpfr_sqrt because

   8005 	  occurring (left space padding without a precision and without a

   8049 2018-07-22  Vincent Lefvre  <vincent (a] vinc17.net>
   8050 
   8051 	[tests/terf.c] Added a testcase for bug reported by Naoki Shibata:

   8053 	(uceil_log2.c:40: MPFR assertion failed: exp < 1023).
   8054 	Increased the number of generic tests in order to reproduce the bug

   8069 
   8070 2018-07-19  Vincent Lefvre  <vincent (a] vinc17.net>

   8079 
   8080 2018-07-18  Vincent Lefvre  <vincent (a] vinc17.net>
   8081 
   8082 	Shared caches: fix and minor changes.
   8083 	  * Fixed detection and use of C11 thread support: the C11 header is
   8084 	    <threads.h>, not <thread.h>.
   8085 	  * Renamed WANT_SHARED_CACHE to MPFR_WANT_SHARED_CACHE for consistency
   8086 	    with the other MPFR_WANT_* macros.
   8087 	  * Added MPFR_THREAD_LOCK_METHOD macro, giving the thread locking
   8088 	    method as a string (when shared caches are enabled).
   8089 	  * doc/README.dev: documented 4 macros for shared caches.
   8090 	  * tests/tversion.c: output MPFR_WANT_SHARED_CACHE and
   8091 	    MPFR_THREAD_LOCK_METHOD information.
   8092 
   8093 	[tests/tconst_pi.c] Removed an incorrect assertion, as the #else would
   8094 	be applicable when WANT_SHARED_CACHE is defined but not HAVE_PTHREAD
   8095 	(which may occur when MPFR_HAVE_C11_LOCK is defined).
   8096 
   8097 	[src/vasprintf.c] Fixed type in partition_number to be consistent with
   8098 	the end of the function.
   8099 
   8100 2018-07-16  Vincent Lefvre  <vincent (a] vinc17.net>
   8101 
   8102 	[src/vasprintf.c] Added 2 FIXME and removed an incorrect MPFR_ASSERTN
   8103 	(which came from r5236).
   8104 
   8105 	[tests/tsprintf.c] Added other tests to check_length_overflow, which
   8106 	would trigger other bugs in src/vasprintf.c (e.g. when removing the
   8107 	other failing tests).
   8108 
   8109 	[tests/tsprintf.c] Added check_length_overflow to check the behavior of
   8110 	mpfr_snprintf on a large number of output characters (> INT_MAX) with
   8111 	size = 0. This test is actually done only if INT_MAX == 2147483647 and
   8112 	currently fails in such a case.
   8113 
   8114 	[src/vasprintf.c] Updated comment about overflow on the number of output
   8115 	characters, taking into account the latest ISO C and POSIX standards.
   8116 
   8117 	[tests/tsprintf.c] Updated a comment.
   8118 
   8119 2018-07-13  Vincent Lefvre  <vincent (a] vinc17.net>
   8120 
   8121 	[src/vasprintf.c] Simplified mpfr_get_str_wrapper.
   8122 
   8123 	[src/vasprintf.c] Added a log message.
   8124 
   8125 	[src/mpfr-impl.h] Added a FIXME: _Decimal128 code and _MPFR_IEEE_FLOATS
   8126 	(which is about binary IEEE-754 floating point) should be unrelated.
   8127 
   8128 	[src/get_d64.c]
   8129 	  * Added FIXME's for get_decimal64_nan and get_decimal64_inf internal
   8130 	    functions: possible issue with _MPFR_IEEE_FLOATS code, which also
   8131 	    seems more complex than the generic code.
   8132 	  * Simplified get_decimal64_zero internal function to generate a
   8133 	    decimal zero directly instead of using the fact that a binary64
   8134 	    zero is also the encoding of a decimal zero (and assuming that
   8135 	    double = binary64 with perfect endianness matching).
   8136 
   8137 	[acinclude.m4] Updated message about the _Float128 support, since
   8138 	this is not just about the compiler.
   8139 
   8140 	[acinclude.m4] Fixed the _Float128 / __float128 detection for NetBSD:
   8141 	Optimization made the "undefined reference" error disappear, so that
   8142 	__float128 was misdetected as being supported.
   8143 
   8144 2018-07-12  Vincent Lefvre  <vincent (a] vinc17.net>
   8145 
   8146 	[acinclude.m4] For the _Float128 / __float128 detection, changed
   8147 	AC_COMPILE_IFELSE to AC_LINK_IFELSE since an error may occur only
   8148 	at link time, such as under NetBSD:

   8151 
   8152 	[src/Makefile.am] Corrected check-exported-symbols to avoid a failure
   8153 	when the default .SHELLFLAGS value is '-ec' (POSIX) instead of '-c'
   8154 	(GNU Make, which is not in POSIX-conforming mode by default).
   8155 	Bug found on FreeBSD 11.1 (Compile Farm @ HouseGordon.com).
   8156 
   8157 2018-07-11  Vincent Lefvre  <vincent (a] vinc17.net>

   8161 
   8162 2018-07-09  Vincent Lefvre  <vincent (a] vinc17.net>
   8163 
   8164 	[doc/mpfr.texi] More changes to Section "Nomenclature and Types";
   8165 	in particular, defined regular numbers and exponents.
   8166 
   8167 	[doc/mpfr.texi] In Section "Nomenclature and Types", removed all the
   8168 	@noindent, whose purpose is unclear (if one needs something special,
   8169 	an itemized list would be better, or possibly @deffn).
   8170 
   8171 	[doc/mpfr.texi] Rewrote the paragraph defining "floating-point number"
   8172 	in Section "Nomenclature and Types", avoiding ambiguities.
   8173 
   8174 2018-07-06  Vincent Lefvre  <vincent (a] vinc17.net>
   8175 
   8176 	[tests/tprintf.c] Grrr... again a copy-paste error. Now OK.
   8177 
   8178 	[tests/{tprintf.c,tsprintf.c}] Corrected the tests added in r12898,
   8179 	but tprintf still fails.
   8180 
   8181 	[tests/tsprintf.c] Corrected the latest tests.
   8182 
   8183 	[tests/tsprintf.c] Added tests (failure on "%09.3Rg" for 1000).
   8184 
   8185 	[tests/tsprintf.c] Corrected comments.
   8186 
   8187 	[tests/{tprintf.c,tsprintf.c}] Added tests (both programs fail).
   8188 
   8189 	[doc/mpfr.texi] Updated the month.
   8190 
   8191 	[src/vasprintf.c] Corrected comments and coding style.
   8192 
   8193 	[src/vasprintf.c] Resolve the FIXME.
   8194 	  * Renamed ip_trailing_zeros to ip_trailing_digits, since when
   8195 	    spec.size == 0, these can be any digits.
   8196 	  * Simplified the buffer_sandwich function since it can be called
   8197 	    only when spec.size != 0, in which case tz (= ip_trailing_digits)
   8198 	    is either 0 or 1 (a trailing zero must be added only when rounding
   8199 	    to the next power of ten in the %f case).
   8200 	  * Corrected/removed/added comments.
   8201 
   8202 	[tests/{tprintf.c,tsprintf.c}] Added tests with powers of ten in all
   8203 	rounding modes and powers of ten + 0.5 in rounding to nearest.

   8223 
   8224 	[tests/tprintf.c] Added more tests of the form 10^i - 1/2.
   8225 
   8226 	[tests/tsprintf.c] Added test_locale() test based on the tprintf.c one.

   8233 
   8234 	[src/vasprintf.c] Renamed mpfr_get_str_aux to mpfr_get_str_wrapper
   8235 	in order to avoid a confusion with the mpfr_get_str_aux function
   8236 	from get_str.c (moreover, this is really a wrapper, which is the
   8237 	reverse of an aux function).
   8238 
   8239 	[tests/tsprintf.c] locale_da_DK() cleanup.

   8256 
   8257 2018-07-04  Vincent Lefvre  <vincent (a] vinc17.net>
   8258 
   8259 	Added MPFR_CHECK_LOCALES environment variable for the tests (to be
   8260 	used by developers): when set, terminate with an error if locales
   8261 	cannot be tested.
   8262 
   8263 2018-07-04  Vincent Lefvre  <vincent (a] vinc17.net>
   8264 
   8265 	[src/vasprintf.c] Fixed several bugs in buffer_sandwich, which could
   8266 	yield memory corruption with non-default memory allocators and other
   8267 	undefined behavior; check the return value when this function is called.
   8268 
   8269 	Details:
   8270 	  * check integer overflow on the size computations;
   8271 	  * computation of q and r without tests;
   8272 	  * fixed the case where r > len (e.g. len = 1 and tz = 1);
   8273 	  * in the loop, increase the str pointer only when needed, otherwise
   8274 	    str could be beyond of the end of the string of the digits, which
   8275 	    is undefined behavior.
   8276 
   8277 	The first consequence of the r > len issue was an incorrect generated
   8278 	string. Moreover, since the generated string was shorter than expected,
   8279 	mpfr_free_str would provide an incorrect buffer size to the "free"
   8280 	function of the current GMP memory allocator. By default, this size is
   8281 	ignored, but it may matter if the memory allocators have been changed
   8282 	with the mp_set_memory_functions GMP function, in which case a possible
   8283 	consequence could be memory corruption.

   8791 	[tests/tgmpop.c] Coding style.
   8792 
   8793 	[tests/tgmpop.c] For mpfr_cmp_q, improved the test where x is NaN by
   8794 	checking all the flags (not just erange) and added a test where y is
   8795 	a NaN rational.
   8796 	Note: this could be used to detect 2 bugs, fixed in r12343 and r12499,
   8797 	respectively.
   8798

   8820 
   8821 	[tests/tdot.c] Various improvements.
   8822 
   8823 	[doc/mpfr.texi] Note that mpfr_dot does not yet handle intermediate
   8824 	underflows either.
   8825 	[src/dot.c] Changed an MPFR_ASSERTD to MPFR_ASSERTN since the assertion
   8826 	is not satisfied on some user inputs. Minor improvements.
   8827 
   8828 	[NEWS] Added mpfr_dot.
   8829

   8862 2018-04-18  Vincent Lefvre  <vincent (a] vinc17.net>
   8863 
   8864 	[tests/tfma.c] Added test_underflow4. This allows to show that the
   8865 	bound MAX (MPFR_PREC (z), MPFR_PREC (s) + 1) in fma.c is optimal:
   8866 	  * If one subtract 1 from the 1st term MPFR_PREC (z), a failure
   8867 	    occurs in test_underflow4.
   8868 	  * If one subtract 1 from the 2nd term MPFR_PREC (s) + 1, a failure
   8869 	    occurs in test_underflow2.
   8870 
   8871 	[configure.ac] For the ICC check, also test __INTEL_COMPILER.
   8872 
   8873 	[configure.ac] Corrected comment for the ICC check (GCC is no longer

   8904 	Note: si functions are not tested yet.
   8905 
   8906 	Replaced mpfr_mul_2exp & mpfr_div_2exp by mpfr_mul_2ui & mpfr_div_2ui,
   8907 	respectively (for the tests, except in reuse.c and in taway.c).
   8908 	Note: As documented, mpfr_mul_2exp & mpfr_div_2exp are only kept for
   8909 	compatibility with MPF; mpfr_mul_2ui & mpfr_div_2ui are preferred.
   8910 
   8911 2018-04-16  Vincent Lefvre  <vincent (a] vinc17.net>
   8912 
   8913 	[TODO] + function to reduce the precision of a variable, with a

   8933 	[src/fma.c] Forgot a MPFR_GROUP_CLEAR.
   8934 
   8935 	[src/fma.c] Simplified the underflow case by using UBF in the

   8943 
   8944 	[tests/tfma.c] Do all the overflow/underflow tests in exponent ranges
   8945 	[-1024,1024], [MPFR_EMIN_MIN,MPFR_EMAX_MAX], and the default one.

   8948 
   8949 2018-04-12  Vincent Lefvre  <vincent (a] vinc17.net>
   8950 
   8951 	[tests/tfma.c] Forgot a cast for C++ compatibility.
   8952 
   8953 	[src/mpfr-impl.h] Reverted r12588: there should be no alignment issues
   8954 	with UBF, since an UBF (__mpfr_ubf_struct) is sometimes regarded as a
   8955 	MPFR number (__mpfr_struct) but not the opposite (or this is just back
   8956 	to __mpfr_ubf_struct).
   8957 
   8958 	[src/fma.c] Simplified the difficult part of the overflow case by
   8959 	using UBF (this also fixes corner cases in huge precision).
   8960 
   8961 	[src/mpfr-impl.h] Added a note about alignment constraints for UBF.
   8962 
   8963 	[src/fma.c] Fixed sign related bug in overflow case.
   8964 	[tests/tfma.c] Added test_overflow5 test for this bug.

   8966 	[tests/tfma.c] In test_overflow4, also test different signs.
   8967 
   8968 	[src/fma.c] Correction for the FIXME from r12403 concerning r12396.
   8969 	The test added in tests/tfma.c r12584 no longer fails.
   8970 
   8971 	[tests/tfma.c] Added a test that fails. It corresponds to the FIXME
   8972 	in src/fma.c about the test on MPFR_GET_EXP (u) - MPFR_GET_EXP (z).
   8973 
   8974 	[src/fma.c] Removed a redundant test since the second condition of
   8975 	the && expression implies the first one.
   8976 	Note: This test came from the time when the precision type was unsigned,
   8977 	in order to make sure that the result of the subtraction was positive.

   9038 2018-04-06  Vincent Lefvre  <vincent (a] vinc17.net>
   9039 
   9040 	[tests/tpow.c] Fixed a test:
   9041 	  * For this test, unsigned long and mpfr_exp_t must both have at least
   9042 	    64 bits.
   9043 	  * Use a hardcoded emax, otherwise the test could fail for mpfr_exp_t
   9044 	    larger than 64 bits (one would not have an overflow as expected).
   9045 
   9046 	[src/pow.c] Fixed the code in case the size of the mpfr_exp_t type
   9047 	would be larger than 256 bits. This is also semantically better.
   9048 
   9049 	Moved the MAX, MIN and ABS macros from tests/mpfr-test.h to

   9406 	[acinclude.m4] Fixed a test, which could define MPFR_INTMAX_WITHIN_LIMB
   9407 	even when not true (MPFR_STAT_STATIC_ASSERT() was just regarded as a
   9408 	function call since the macro was not defined, thus did not yield an

   9414 
   9415 	Removed trailing spaces.
   9416 
   9417 	Updated support for binary128:
   9418 	  * __float128 was changed to _Float128 (ISO/IEC TS 18661) in r12391;
   9419 	    also changed the suffix of the constants from "q" to "f128".
   9420 	  * Use __float128 with the "q" suffix as a fallback in order to avoid
   9421 	    regressions with GCC 6- and with C++ mode (g++).
   9422 	    As documented in the GCC manual, this is entirely compatible on most
   9423 	    platforms where both are supported: _Float128 and __float128 are the
   9424 	    same type, and it could be checked that the following prototypes are
   9425 	    equivalent (as expected):
   9426 	      _Float128 f (__float128)
   9427 	      __float128 f (_Float128)
   9428 	    The only potential issues would be on hppa and IA-64 HP-UX, where
   9429 	    __float128 is an alias for "long double" instead of _Float128, in
   9430 	    case the ABI would be different (I have no information about this)
   9431 	    and both would be mixed up with software using the MPFR conversion
   9432 	    functions for binary128 via __float128 or "long double". The worst
   9433 	    thing that could happen is a link error. If the link is accepted,
   9434 	    everything should be fine as the representation doesn't change.

   9967 
   9968 	[src/expm1.c] It seems that code removed in r12273 wasn't necessarily
   9969 	dead code with mpfr_exp_t > long (-D_MPFR_EXP_FORMAT=4 needed) because
   9970 	for MPFR_SMALL_INPUT_AFTER_SAVE_EXPO, err would be limited to -LONG_MAX
   9971 	and precisions larger than LONG_MAX could be problems. The -LONG_MAX
   9972 	bound from r4127 was arbitrary and only used to simplify the code due
   9973 	to the fact that mpfr_cmp_si compares to a "long" argument. But now we
   9974 	have the internal mpfr_get_exp_t function, allowing us to avoid this
   9975 	arbitrary bound (fixing the code and making it more efficient for these
   9976 	extreme cases) and simplify the code even more.

   10033 	with a simple "./configure").
   10034 
   10035 	[src/exp_2.c] Note that the internal behavior depends on whether
   10036 	MPFR_LONG_WITHIN_LIMB is defined or not (see also r12253). This
   10037 	should not matter, possibly except in case of bug, like currently.

   10057 
   10058 	[tests/tsub.c] Added bug20180215 test currently failing, found from a
   10059 	failure using -DMPFR_GENERIC_ABI in CFLAGS and the --enable-assert=full
   10060 	configure option; but the test had to be extended so that it also fails
   10061 	with a simple "configure", i.e. without -DMPFR_GENERIC_ABI in CFLAGS

   10090 
   10091 	[src/sub1sp.c] In mpfr_sub1sp, initialize k only once. This slightly
   10092 	simplifies the code and avoids a -Wmaybe-uninitialized warning from
   10093 	GCC. The only failure on a 64-bit Linux machine is tsub1sp, due to
   10094 	an assertion failure in mpfr_sub1sp, as before this change.

   10126 	[src/add1sp.c] Improved comments and other minor changes.
   10127 
   10128 	[src/add1sp.c] In the generic code of mpfr_add1sp, fixed the computation
   10129 	of the round and sticky bits from r12220. At the same time, improved the
   10130 	handling of MPFR_RNDF in this part of the code:
   10131 	  * The "while" loop to compute the sticky bit is no longer done in this
   10132 	    case (the sticky bit does not matter).
   10133 	  * The "goto" is avoided.
   10134 
   10135 	[tests/tadd.c] Added 2 tests that fail starting with r12220.

   10145 	  like in mpfr_fmma.
   10146 	[src/hypot.c] Updated a comment: The problem that would come from an
   10147 	  underflow in y^2, in particular because x was scaled in order to
   10148 	  avoid an overflow in x^2, has been avoided by using a FMA (though
   10149 	  still buggy for these cases, as mentioned just above).

   10180 
   10181 	[tests/t*random*.c]
   10182 	  * Replaced calloc + free by tests_allocate + tests_free as usual.
   10183 	  * trandom.c, turandom.c: do bitwise operations in unsigned arithmetic.
   10184 
   10185 	[tests/t*random*.c]
   10186 	  * Replaced some fprintf with stderr by printf (but not those
   10187 	    concerning memory allocation errors).
   10188 	  * Do bitwise operations in unsigned arithmetic.
   10189 	  * Formatting.
   10190 
   10191 	[tests] Formatting.
   10192 
   10193 	[tests/tests.c] Make stderr unbuffered again.
   10194 	Note for the history: both stdout and stderr were made unbuffered in
   10195 	r2361, then all stderr were changed to stdout (and the corresponding
   10196 	setbuf on stderr removed) in r2449 for consistency, but stderr was
   10197 	used later for specific cases (e.g. memory allocation errors or when
   10198 	stdout is already used for something else), and it is also used for
   10199 	assertion failures. Thus the setbuf on stderr is still needed.
   10200 
   10201 	[tests] Fixed the cases where tests_start_mpfr was called too late,
   10202 	i.e. after potential output (to stdout).
   10203 	  * tremquo.c: moved the call to tests_start_mpfr to the beginning.
   10204 	  * tset_float128.c, tset_ld.c: removed the optional, obsolete code
   10205 	    setting the FPU control word; MPFR_FPU_PREC can be used instead
   10206 	    (see tests.c).
   10207 
   10208 	Reverse-merged r12181 since tests_start_mpfr disables stdout buffering,
   10209 	so that the fflush() are unnecessary.
   10210 
   10211 	[tests/tabort_*.c] Flush stdout after a printf(), as an abort() is
   10212 	expected. This is needed on platforms where abort() does not flush
   10213 	the stdio streams, such as with the GNU C Library (glibc) 2.27.

   10222 
   10223 	[tests/tdiv_ui.c] In corner_cases, test larger values for xn,
   10224 	as suggested by Paul, allowing one to cover case 2 for both
   10225 	sb=0 and sb=1. Value coverage is now complete.
   10226 
   10227 	[tests/tdiv_ui.c] Updated midpoint_exact to also test the divisor
   10228 	ULONG_MAX, allowing one to cover cases 3 and 4.
   10229 
   10230 	[tests/tdiv_ui.c] Added tests with simple midpoint and exact cases.
   10231 	This covers case 9, sb=0.
   10232 
   10233 	Added a case for the value coverage for tdiv_ui.
   10234 	 Now, on a 64-bit Linux machine:
   10235 	    mpfr_div_ui not tested on case 2, sb=0

   10239 	    mpfr_div_ui not tested on case 9, sb=0
   10240 
   10241 	Added value coverage for tdiv_ui (combinations of rb and sb in the
   10242 	different cases of the mpfr_div_ui code).
   10243 	 Currently on a 64-bit Linux machine:
   10244 	    mpfr_div_ui not tested on case 2, sb=0
   10245 	    mpfr_div_ui not tested on case 3, sb=0
   10246 	    mpfr_div_ui not tested on case 8, sb=0
   10247 
   10248 	[src/div_ui.c] Case tmp[yn] != 0: simplified code since u  2.
   10249 
   10250 	[src/div_ui.c] Case tmp[yn] == 0:
   10251 	  * corrected/improved comments;
   10252 	  * simplified condition rb && sb to rb (since if rb  0, then r  0,
   10253 	    so that the current sb  0);
   10254 	  * replaced "& (~MPFR_LIMB_HIGHBIT)" by "<< 1" (should be simpler).

   10399 	[src/lngamma.c] Fixed mpfr_lgamma bug for tiny negative x, in case
   10400 	emax < exponent of the result (the issue was an overflow in the "fast"

   10407 
   10408 	[tests/tgeneric.c] Do several overflow/underflow tests instead of 1, and
   10409 	this for each precision. This allows one to detect the mpfr_ai bug found
   10410 	and fixed on 2018-01-07 (with 32-bit *and* 64-bit ABI):
   10411 	  https://sympa.inria.fr/sympa/arc/mpfr/2018-01/msg00001.html

   10432 	Note: For the versions of the manual generated with TeX (PDF/DVI/PS),

   10632 
   10633 	[src/div.c] fixed bug in mpfr_div2_approx()
   10634 	[tests/tdiv.c] added non-regression test

   10637 2017-12-18  Vincent Lefvre  <vincent (a] vinc17.net>
   10638 
   10639 	[doc/algorithms.tex] mpfr_tanh: resolved both FIXME's.
   10640 
   10641 	[doc/algorithms.tex] mpfr_tanh: corrected a part of the error analysis
   10642 	(2^k+4  |theta_4|^(1/2) was not necessarily true, since theta_4 can
   10643 	be very small). As a consequence, the lemma can be simplified/improved
   10644 	(first FIXME). Added a second FIXME on a condition that is not checked.
   10645 
   10646 	[doc/algorithms.tex] mpfr_tanh: missing absolute value; added a \cdot.
   10647 
   10648 	Removed trailing whitespace.
   10649 
   10650 	[doc/algorithms.tex] Added another \cdot for readability.

   10656 2017-12-18  Vincent Lefvre  <vincent (a] vinc17.net>
   10657 
   10658 	[doc/algorithms.tex] Minor corrections for hyperbolic tangent function:
   10659 	  * "e" had two different meanings (BTW, the constant e should actually
   10660 	    be written \mathrm{e} everywhere in the document).
   10661 	  * Use \left...\right instead of |...| when it contains an expression
   10662 	    starting with \log (the latter was confusing pdflatex, which added
   10663 	    a spurious space before \log).
   10664 	  * Added some \cdot for better readability.
   10665 
   10666 2017-12-18  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   10667

   10669 	[tests/texp2.c] added non-regression test
   10670 
   10671 	[tests/ttanh.c] added test for bug in mpfr_tanh
   10672 	[doc/algorithms.tex] fixed error analysis for mpfr_tanh
   10673 	[src/tanh.c] fixed error analysis
   10674 	Note after r12016: Even though mpfr_tanh was incorrect, the failure
   10675 	of the test added in ttanh.c was actually *only* due to a bug in the
   10676 	mpfr_div code specific to the trunk (fixed in r12002), i.e. this was
   10677 	not a non-regression test for the mpfr_tanh bug itself (in particular,
   10678 	this test does not introduce a failure in the 3.1 branch, which still
   10679 	has the same incorrect mpfr_tanh code but a correct mpfr_div).

   10681 2017-12-18  Vincent Lefvre  <vincent (a] vinc17.net>

   10712 
   10713 	[src/root.c] Minor comment correction.
   10714 
   10715 	[src/root.c] Completed fix from r11978, as x=-1 was affected too. Also
   10716 	  added comments explaining that mpfr_root_aux assumes |x|  1 and why.
   10717 	  Hence the need of a filter on |x| = 1.
   10718 	[tests/troot.c] Added test for x = -1.

   10741 	that the bug fixed in r11974 does not occur in other parts of the code.
   10742 	BTW, there is much duplicate code, as shown by the grep output, and
   10743 	using macros could have avoided that, making bugs easier to reproduce
   10744 	(since a same bug would be duplicate several times).

   10766 
   10767 	[src/mpfr-cvers.h] Removed a useless test for __MPFR_STDC, as one just
   10768 	needs to check whether we have a C99, C11, etc. implementation (if not
   10769 	done via a configure test). Particular incompatibilities with the C90
   10770 	standard should always be checked via a configure test.
   10771

   10790 
   10791 	Completed r11955: There were also DEBUG macros under the "tests"
   10792 	directory. Since such macros can still be useful in case a test failure,
   10793 	replaced them by MPFR_DEBUG to avoid issues with CI builds that define
   10794 	the DEBUG macro. But an environment variable would be a better solution
   10795 	(see MPFR_DEBUG_BADCASES as an example).
   10796

   10881 	    containing pool related code.
   10882 	  * src/mpfr-impl.h, src/pool.c: cleanup and fixes. In particular:
   10883 	      - renamed MPFR_MY_MPZ_INIT to MPFR_POOL_NENTRIES;
   10884 	      - no longer use GMP's symbols __gmpz_init, etc. directly;
   10885 	      - improved the condition for mpfr_mpz_init2;
   10886 	      - fixed the condition in mpfr_mpz_clear (we want to consider

   11053 	[doc/README.dev] Typo.
   11054 
   11055 	Two fixes for the check-gmp-symbols make rule:
   11056 	  * Use $(COMPILE) instead of $(CC) to get the usual compilation flags
   11057 	    (in particular, the -I flags may be important to find gmp.h and to

   11067 
   11068 	Added comment about the check-gmp-symbols make rule (added in r11865).
   11069 
   11070 	Added check-gmp-symbols make rule to check that MPFR does not use
   11071 	GMP internal symbols.

   11083 	[src/fpif.c] Fixed the sign bug for mpfr_fpif_import.
   11084 
   11085 	[tests/tfpif.c] In doit(), before the call to mpfr_fpif_import(), set
   11086 	the sign of the target to the opposite of the expected sign. Thus, if
   11087 	mpfr_fpif_import forgets to set the sign, this will be detected. And
   11088 	a failure actually occurs now!
   11089 
   11090 	[tests/tfpif.c] For mpfr_fpif_import, check the precision too.
   11091 
   11092 	[doc/mpfr.texi,src/fpif.c] For mpfr_fpif_import, in case of failure,
   11093 	the argument x is either unchanged or set to NaN, to make sure that
   11094 	x has valid contents (otherwise this could yield erratic behavior).
   11095 
   11096 	[src/fpif.c] For mpfr_fpif_import, replaced an assertion by a failure
   11097 	(since the full format is not described in the manual and MPFR cannot
   11098 	currently generate such a case, this is OK).
   11099 
   11100 	[tests/tfpif_r1.dat] Fixed an obvious error (incorrect sign of 0).
   11101 
   11102 	[tests/tfpif.c] Output more information in case of error.
   11103

   11105 
   11106 	[src/fpif.c] Fixed some bugs (though unlikely to occur in practice).
   11107 	Added comments. Minor code improvement.
   11108 
   11109 	Got rid of the useless SIZE_MAX macro.
   11110 	  * src/vasprintf.c: replaced SIZE_MAX by (size_t) -1, already used
   11111 	    in some other files.
   11112 	  * acinclude.m4: no longer use gl_SIZE_MAX (from m4/size_max.m4).
   11113 	  * Removed m4/size_max.m4 as it is no longer needed (note that the
   11114 	    definition of SIZE_MAX by this file was unnecessarily complex
   11115 	    and potentially incorrect on some platforms).
   11116 
   11117 	[src/fpif.c] Added static assertions in mpfr_fpif_import().
   11118 
   11119 	[src/fpif.c] Improved a test (mpfr_regular_p  !MPFR_IS_SINGULAR).
   11120 
   11121 	[src/mpfr-impl.h] Added a note about the use of the MPFR_IS_PURE_*(x)
   11122 	and MPFR_IS_SINGULAR*(x) macros.
   11123 
   11124 2017-11-27  Vincent Lefvre  <vincent (a] vinc17.net>
   11125 
   11126 	[src/fpif.c] Added format description from past mail messages, to be
   11127 	checked in case of change (+ FIXME for NaN). Minor code improvement.
   11128 
   11129 	[tests/tfpif.c] Added TODO's (but the failure should be fixed first).
   11130 
   11131 	[src/fpif.c] Clarified sign variable.
   11132 
   11133 	[tests/tfpif.c] Use SAME_VAL instead of mpfr_cmp. This triggers a bug
   11134 	that was not detected yet.
   11135 
   11136 	[tests/tfpif.c] Split the main test function into:
   11137 	  * doit(): keep only the tests that depend on the precisions.
   11138 	  * check_bad(): tests for bad file/data; precisions are not involved.
   11139 
   11140 	[tests/tfpif.c] Improved a test (NaN checking). Added comments.
   11141 
   11142 	[tests/tfpif.c] Removed a TODO done in r10326 and r10338.
   11143 
   11144 	Updated autogen.sh so that doc/texinfo.tex isn't replaced.
   11145 
   11146 	Added doc/texinfo.tex file from Texinfo 6.5 since the version installed
   11147 	by Automake (via "autoreconf -i" as called by autogen.sh) is obsolete:
   11148 	more than 4 years older than the current version!
   11149 
   11150 	[doc/mpfr.texi] Updated a comment about a bug in Texinfo.

   11153 
   11154 	[tests/tset_exp.c] Check mpfr_get_exp too (with two additional tests
   11155 	for mpfr_set_exp).
   11156 
   11157 	[tests/texceptions.c] Minor improvements.
   11158 
   11159 	[doc/mpfr.texi] For mpfr_get_exp, document that x can be outside of

   11199 	  * Replaced test + abort() by the more informative MPFR_ASSERTN().
   11200 	  * Also check that the allocator is the current GMP one (this would
   11201 	    fail with MPFR 3.1.6, where the allocation functions are memorized
   11202 	    the first time they are seen).
   11203 
   11204 	mpfr_mp_memory_cleanup() now returns an error code (currently always 0)
   11205 	to avoid a future prototype change in case errors would be possible.

   11219 
   11220 	[tests/tabs.c] More tests on mpfr_abs, including the ternary value
   11221 	and the NaN flag and sign bit for NaN.
   11222 
   11223 	[tests/tabs.c] Coding style.
   11224 
   11225 	[tests/tset.c] For mpfr_neg on NaN, also check that the variable is

   11236 	in both ways.

   11245 
   11246 	[src/neg.c] Refactored code (BTW, this was not a bug as the sign of NaN
   11247 	is currently unspecified for mpfr_neg).

   11466 	[tests] Solve issues with the incorrect use of mpfr_sgn, and make sure
   11467 	that this cannot happen again without being detected: on zero, +1 or -1
   11468 	was sometimes expected to check the sign of zero, but mpfr_sgn actually
   11469 	returned 0, so that the check always succeeded whatever the sign of the
   11470 	null result.
   11471 	  * mpfr-test.h: define a new mpfr_sgn macro that fails when used on NaN
   11472 	    or zero (whose sign is not +1 or -1), except when MPFR_TESTS_TSGN is
   11473 	    defined.

   11476 	    the incorrect use of mpfr_sgn; some other related improvements.
   11477 	    Note: in tset.c, a "mpfr_sgn (x) < 0" test had to be replaced by
   11478 	    "MPFR_IS_POS (x)" since we really want to test whether the sign
   11479 	    is positive (not negative).
   11480 	  * tdiv.c, tmul.c, tui_div.c: simplified some tests, in particular to
   11481 	    avoid a failure with the new mpfr_sgn macro for the tests; here,
   11482 	    the use of mpfr_sgn was correct, but one could do simpler.
   11483 	  * tgmpop.c: replaced "mpfr_sgn (z)" by "(mpfr_sgn) (z)" to avoid the
   11484 	    new mpfr_sgn macro (here, we really want the mathematical sign).
   11485 	  * tsgn.c: define MPFR_TESTS_TSGN as the goal of this program is to
   11486 	    test mpfr_sgn itself (both the function and the macro in mpfr.h).
   11487

   11499 	  * use of SAME_SIGN for better clarity.
   11500 
   11501 	[tests/tfma.c] Similar change to what was done in tfms.c (may be useful
   11502 	in the future).
   11503 
   11504 	[tests] Got rid of the use of mpfr_print_binary, in general with
   11505 	mpfr_dump. Replaced some "mpfr_out_str (stdout, 2, ...)" by mpfr_dump
   11506 	for consistency or as improvements. Some other corrections in the

   11522 
   11523 	[tests/troot.c]
   11524 	  * Use mpfr_set_zero instead of mpfr_set_ui / mpfr_neg (like what was
   11525 	    done for the infinity, using mpfr_set_inf).
   11526 	  * For exact cases (NaN, Inf, 0), check that the ternary value is 0.
   11527 
   11528 	[tests/troot.c] For the root(0,k) tests, before calling the function,
   11529 	we set the target y to NaN with the wrong sign, so that if the code of
   11530 	the function forgets to do something, this will be detected.
   11531 
   11532 	[tests/troot.c] Also check root(+0,42) and root(-0,17) for completeness.
   11533 
   11534 	[tests/troot.c] Really check the sign of the result 0 (the old test

   11536 
   11537 	[doc/mpfr.texi] Updated the month.
   11538 
   11539 	New mpfr_rootn_ui function; mpfr_root deprecated.
   11540 	  * src/root.c: mpfr_rootn_ui is now the main code, and mpfr_root calls
   11541 	    mpfr_rootn_ui.
   11542 	  * src/mpfr.h: added mpfr_rootn_ui prototype; marked mpfr_root as
   11543 	    deprecated.
   11544 	  * Added tests/trootn_ui.c (includes troot.c).
   11545 	  * tests/troot.c: made it usable (via #include) by the new trootn_ui.c
   11546 	    test.
   11547 	  * tests/Makefile.am: added trootn_ui; at the same time, corrected the
   11548 	    order of the test programs (lexicographic, with exceptions).

   11648 	updated for mpfr-3.1.6-rc1
   11649 
   11650 2017-08-28  Vincent Lefvre  <vincent (a] vinc17.net>
   11651 
   11652 	[tools/mpfrlint] Run tools/ck-version-info.
   11653 
   11654 	[tools/mpfrlint] Updated a message due to the change in r11673.
   11655 
   11656 	[doc/README.dev] "To make a release": The DLL version may need to be
   11657 	updated too.
   11658 
   11659 	[configure.ac] Added a comment about the DLL version.
   11660 
   11661 	[configure.ac] Updated DLL version to 6 (cur - age).
   11662 
   11663 	[tools/{ck-copyright-notice,ck-inits-clears}] Ignore Emacs lock files
   11664 	(symbolic links) to avoid a failure when a file is being edited.
   11665 
   11666 	[tools] Clean up.
   11667 	  * Renamed check_inits_clears to ck-inits-clears (the other "check"
   11668 	    scripts have a name starting with "ck-").
   11669 	  * mpfrlint: updated the invocation of this test, simplifying it to
   11670 	    make it similar to the other ones (it was based on old code).
   11671 
   11672 2017-08-27  Vincent Lefvre  <vincent (a] vinc17.net>
   11673 
   11674 	[tests/turandom.c] Disabled the reprod_abi test with GMP < 4.2.0
   11675 	since the hardcoded values would be different.
   11676 
   11677 2017-08-25  Vincent Lefvre  <vincent (a] vinc17.net>
   11678 
   11679 	[src/mpfr-impl.h] Replaced
   11680 	  (MPFR_LIKELY(expr)) || (ASSERT_FAIL(expr),0)
   11681 	by
   11682 	  (MPFR_LIKELY(expr)) || (ASSERT_FAIL(expr),MPFR_ASSUME(expr),0)
   11683 	as a workaround to the fact that mpfr_assert_fail is not marked as
   11684 	"no return" (bug 21415). Thus, after this code, expr must be true.
   11685 
   11686 	[tests/turandom.c] Check that the behavior does not depend on the
   11687 	platform ABI or MPFR version.
   11688 
   11689 	[tests/turandom.c] Corrected error messages after r11661.
   11690 
   11691 	[tests/turandom.c] Renamed "reprod" to "reprod_rnd_exp" (reproducibility
   11692 	test with several rounding modes and exponent ranges), because a second
   11693 	reproducibility test will be added.
   11694 
   11695 	[tests/turandom.c]
   11696 	  * In underflow_tests, test the flags in all cases (not just when the
   11697 	    returned result is 0), possibly by first computing the result in a
   11698 	    large exponent range.
   11699 	  * Since the flags are now well tested in underflow_tests, no longer
   11700 	    test them in the second test of test_urandom for k = 0, which was
   11701 	    the incorrect test that was failing (see r11659).
   11702 
   11703 	[tests/turandom.c] Do some test several times in order to trigger
   11704 	a "mpfr_urandom() returns incorrect flags for emin = 1" failure
   11705 	when GMP_CHECK_RANDOMIZE is not set (default).
   11706 	Note: It is this test that is actually wrong (it corresponds to the
   11707 	old behavior, currently found in the 3.1 branch, and was not updated
   11708 	after the mpfr_urandom code was fixed).
   11709 
   11710 	[tests/turandom.c] Code formatting. Added an assertion.
   11711 
   11712 2017-08-24  Vincent Lefvre  <vincent (a] vinc17.net>
   11713 
   11714 	[tests/turandom.c] Check that the behavior of mpfr_urandom() does not
   11715 	depend on the rounding mode.
   11716 
   11717 	[doc/mpfr.texi] Completed the description of mpfr_urandom.
   11718 
   11719 	[src/urandom.c] Completed comment.
   11720 
   11721 2017-08-23  Vincent Lefvre  <vincent (a] vinc17.net>
   11722 
   11723 	[tests/turandom.c] In bug20170123, use a local gmp_randstate_t variable
   11724 	instead of mpfr_rands, due to the gmp_randseed_ui (see r11653).
   11725 
   11726 	[tools/mpfrlint] Detect the use of gmp_randseed* functions on mpfr_rands
   11727 	(this is bad practice: this would affect later tests, defeating the
   11728 	purpose of GMP_CHECK_RANDOMIZE; another gmp_randstate_t variable should
   11729 	be used instead of mpfr_rands).
   11730 
   11731 	[tests/{mpfr-test.h,tests.c}] Got rid of __gmp_randstate_struct, which
   11732 	is internal to GMP: its use came from very old code (r2330 in 2003-06)
   11733 	and it is no longer needed.
   11734 
   11735 	[tests/turandom.c] Disabled a test with GMP < 4.2.0 since it depends on
   11736 	a specific behavior of the random generator, which changed in GMP 4.2.0
   11737 	(the test would probably fail with such old GMP versions).
   11738 
   11739 	[src/urandom.c] Partly rewrote mpfr_urandom() so that the next
   11740 	  random state no longer depends on the current exponent range
   11741 	  and the rounding mode, and that the exceptions due to the
   11742 	  rounding of the random number are now correctly generated.
   11743 	[doc/mpfr.texi] Updated the mpfr_urandom() documentation and
   11744 	  updated Section "API Compatibility / Changed Functions" to
   11745 	  mention the change in MPFR 4.0.
   11746 	[NEWS] Mentioned the change for MPFR 4.0.
   11747 
   11748 2017-08-22  Vincent Lefvre  <vincent (a] vinc17.net>
   11749 
   11750 	[src/urandom.c] Minor change about underflow, following the usage.
   11751 
   11752 	[tests/turandom.c] Added inex test for the underflow & overflow tests.
   11753 
   11754 	[tests/turandom.c] Added overflow tests.
   11755 
   11756 	[tests/turandom.c] Indentation.
   11757 
   11758 	[tests/turandom.c] Added underflow tests.
   11759 
   11760 	[tests/turandom.c] With mini-gmp, omit another test that assumes
   11761 	a deterministic random generator.
   11762 
   11763 	[src/urandom.c] Bug fix: the inexact flag was not set on underflow.
   11764 
   11765 	[tests/turandom.c] Added tests of the flags. This currently yields
   11766 	a failure (inexact flag not set on underflow).
   11767 
   11768 	[tests/turandom.c] Added a test of the underflow flag.
   11769 
   11770 2017-08-21  Vincent Lefvre  <vincent (a] vinc17.net>
   11771 
   11772 	[src/urandom.c] Set the underflow flag if the drawn exponent is less
   11773 	than emin. This corresponds to "underflow before rounding" while the
   11774 	normal rule in MPFR is "underflow after rounding". Thus this needs to
   11775 	be fixed.
   11776 	Note: This simple change has been done so that it can be merged with
   11777 	the 3.1 branch. But this will not be fixable in the 3.1 branch since
   11778 	the significand is not drawn in this case, and drawing the significand
   11779 	to determine whether there is an underflow would change the state of
   11780 	the PRNG at the end of the function, breaking the ABI and the users'
   11781 	expectations.
   11782 
   11783 	[src/urandom.c] Updated comments about overflow and its flag.
   11784 
   11785 	[src/urandom.c] Simplified the code, but, except for precision 1,
   11786 	without changing the state of the PRNG.
   11787 	Note: The code could be simplified even further, but the goal of the
   11788 	current change is to allow it to be merged with the 3.1 branch (where
   11789 	precision 1 is not supported) without too many conflicts.
   11790 
   11791 	[src/urandom.c] Moved some code without consequences. Updated comments.
   11792 
   11793 	[src/urandom.c] Useless parentheses; reformatting.
   11794 
   11795 2017-08-17  Vincent Lefvre  <vincent (a] vinc17.net>
   11796 
   11797 	[src/set_float128.c] No longer depend on the native FP type "double"
   11798 	(via mpfr_set_d), avoiding the usual precision issues with the x87
   11799 	traditional FPU in particular. Use the internal representation with
   11800 	limbs, instead. The code is simpler and should also be faster.
   11801 	Note: together with r11627, this avoids the tset_float128 failure
   11802 	with the "-m32 -mpc32" GCC options.
   11803 
   11804 	[src/get_float128.c] Removed variable z (no longer useful).
   11805 
   11806 	[src/get_float128.c] No longer depend on the native FP type "double"
   11807 	(via mpfr_get_d), avoiding the usual precision issues with the x87
   11808 	traditional FPU in particular. Use the internal representation with
   11809 	limbs, instead. The code is simpler and should also be faster.
   11810 
   11811 2017-08-14  Vincent Lefvre  <vincent (a] vinc17.net>
   11812 
   11813 	[src/get_float128.c] Fixed the remaining cases of mpfr_get_float128
   11814 	(when the value is below the smallest subnormal in absolute value).
   11815 
   11816 	[src/get_float128.c] Partly fixed mpfr_get_float128 when it underflows.
   11817 	[tests/tset_float128.c] Added tests for small values, in particular
   11818 	  involving underflows (and subnormals).
   11819 
   11820 2017-08-13  Vincent Lefvre  <vincent (a] vinc17.net>
   11821 
   11822 	[src/get_float128.c] Reverted r11623 (a note mainly for the 3.1 branch,
   11823 	which actually doesn't support __float128).
   11824 
   11825 2017-08-12  Vincent Lefvre  <vincent (a] vinc17.net>
   11826 
   11827 	[src/get_float128.c] Updated the FIXME.

   11856 	[NEWS] Mention the use of the old dtags under Linux (see r11588).
   11857 
   11858 	[src] Moved mpfr_vasprintf from vasprintf.c to printf.c and updated
   11859 	file descriptions for consistency (vasprintf.c should probably be
   11860 	renamed later to something like printf_aux.c).
   11861 
   11862 	[src/printf.c] Updated a comment (taking r11269 into account).
   11863 
   11864 	[src/vasprintf.c] Added an assertion.

   11872 
   11873 	[tools/mpfrlint] Detect "mpfr-impl.h" inclusion by the test programs:

   11993 	[doc/mpfr.texi] Updated the month.
   11994 
   11995 	Update about MPFR_RNDF (faithful rounding):
   11996 	  * NEWS: mention that it is partially supported (should be updated
   11997 	    once MPFR_RNDF is completely supported).
   11998 	  * TODO: moved an item to the right place (MPFR_RNDF is not removed
   11999 	    from the TODO because it is not completely supported yet).
   12000 	  * doc/mpfr.texi: added a FIXME about the partial support.

   12002 2017-05-31  Vincent Lefvre  <vincent (a] vinc17.net>
   12003 
   12004 	[src/{atanh.c,log1p.c}]
   12005 	  * Replaced mpfr_get_exp by MPFR_GET_EXP (so that the exponent is
   12006 	    checked with --enable-assert).
   12007 	  * For a test, doing the division first should be better.

   12009 2017-05-31  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   12010 
   12011 	improved log1p and atanh for small inputs
   12012 
   12013 	added expm1 to mbench
   12014 
   12015 	added log1p to mbench

   12018 
   12019 	[doc/mpfr.texi] Updated the month.
   12020 
   12021 	Removed trailing spaces.
   12022 
   12023 	[tests] Code simplification and improvement by using SAME_VAL().
   12024 
   12025 	[tests/tbeta.c] Replaced not_same() by the simpler ! SAME_VAL().
   12026 
   12027 	[src/sum.c] Code reindentation due to a new test for MPFR_RNDF support,
   12028 	and other minor changes in formatting and comments.
   12029 
   12030 	[doc/sum.txt] Typo in the MPFR_RNDF text.
   12031 
   12032 	Merged the "faithful" branch into the trunk:
   12033 	faithful rounding (MPFR_RNDF).
   12034 
   12035 	[tests/tgeneric.c] For MPFR_RNDF, replaced EQUAL() by SAME_VAL(),
   12036 	which also tests the sign (to distinguish +0 and -0).
   12037 
   12038 	[tests/tui_sub.c] Avoid a failure in 32-bit ABI by replacing
   12039 	RND_LOOP by RND_LOOP_NO_RNDF.
   12040 
   12041 	Merged the latest changes from the trunk.
   12042 
   12043 2017-05-29  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   12044 
   12045 	added new reference
   12046 
   12047 2017-05-24  Vincent Lefvre  <vincent (a] vinc17.net>
   12048 
   12049 	[tests/tsprintf.c] Fixed setlocale usage (problem detected with MinGW)
   12050 	by not using the returned string any longer. Indeed, ISO C99 says that
   12051 	this string "may be overwritten by a subsequent call to the setlocale
   12052 	function".
   12053 
   12054 	[src] Moved "#include <errno.h>" from printf.c to vasprintf.c
   12055 	(this should have been done in r5230, where EOVERFLOW was moved).
   12056 	This fixes the "Got r = -1, errno = 0" errors in tprintf with
   12057 	MPFR_CHECK_LARGEMEM=1.
   12058 
   12059 	[src/vasprintf.c] Added overflow detection at the end (due to the switch
   12060 	to mpfr_intmax_t for the string length in the string_buffer structure,
   12061 	it was no longer detected; however, this bug was not normally visible in
   12062 	the tests because here, a negative value was returned thanks to wrapping
   12063 	in a type conversion and the negative value was changed to the expected
   12064 	-1 value in printf.c).
   12065 
   12066 	[src/vasprintf.c] Added log messages.
   12067 
   12068 	[src/vasprintf.c] In case of overflow, do not stop before everything has
   12069 	been processed, allowing the %...n arguments to be filled, as decided.
   12070 
   12071 	[tests/tprintf.c] check_long_string() error handling: initialize n2 to
   12072 	an invalid value and do all tests before exiting.
   12073 
   12074 	[src/vasprintf.c] Fixed some parts of overflow tracking.
   12075 
   12076 	[tests/tprintf.c] More detailed error message.
   12077 
   12078 	[tests/tprintf.c] Added tests with %ln.
   12079 
   12080 	[tests/tprintf.c] Improved check_vprintf_failure().
   12081 
   12082 	[src/vasprintf.c] Fixed the handling of the 'n' format specifier
   12083 	  for size = 0, still allowing its support in case of overflow on
   12084 	  the return value (i.e. when the number of characters that would
   12085 	  have been output is > INT_MAX).
   12086 	  Note: full support in case of overflow is still limited by GMP
   12087 	  and the C library.
   12088 	[tests/tprintf.c] Increased the memory needed in check_long_string().
   12089 
   12090 2017-05-23  Vincent Lefvre  <vincent (a] vinc17.net>
   12091 
   12092 	[src/mpfr-intmax.h] Define mpfr_uintmax_t and MPFR_INTMAX_MAX too.
   12093 	However, this will not necessarily be used by src/vasprintf.c, as
   12094 	this can be regarded as an EOVERFLOW error for which the behavior
   12095 	on the %...n values is not specified, i.e. we may not need to
   12096 	support size values larger than INT_MAX.
   12097 
   12098 2017-05-22  Vincent Lefvre  <vincent (a] vinc17.net>
   12099 
   12100 	[src/vasprintf.c] In a macro definition, changed a parameter to
   12101 	lowercase so that it doesn't look like a constant to mpfrlint.
   12102 
   12103 	[src/vasprintf.c] Added a FIXME for the percent_n() / mixed() bug due
   12104 	to the 'n' format specifier with size = 0. The way to fix this issue
   12105 	depends on the specifications in case of overflow on the return value,
   12106 	and for POSIX, they are unclear. Waiting for comments...
   12107 
   12108 	[src/mpfr-intmax.h] Define mpfr_intmax_t as being the largest
   12109 	signed integer type available for the MPFR build. It will be
   12110 	useful for the formatted output functions (src/vasprintf.c) to
   12111 	handle the 'n' format specifier, assuming that the value may
   12112 	be larger than INT_MAX, which is possible assuming that the
   12113 	C standard has a defect in the corresponding specification:
   12114 	https://sourceware.org/bugzilla/show_bug.cgi?id=21360
   12115 
   12116 	[tests/tsprintf.c] Added explanation for the bugs triggered by
   12117 	percent_n() and mixed().
   12118 
   12119 	[tests/tsprintf.c] Added percent_n() test to reproduce the bug found
   12120 	in mixed(), test without random data.
   12121 
   12122 	[src/vasprintf.c] In partition_number(), complete check for overflow
   12123 	on total.
   12124 
   12125 	[src/vasprintf.c] Partially fixed check for integer overflow when
   12126 	the long and int types have the same size.
   12127 
   12128 	[src/vasprintf.c] With assertions enabled, check that the number of
   12129 	characters to be written computed in partition_number() corresponds
   12130 	to what is really written.
   12131 
   12132 	[src/vasprintf.c] Fixed the bug triggered by the da_DK locale test: the
   12133 	computation of the number of characters to be written was incorrect in
   12134 	partition_number() when the thousands separator was not empty. This bug
   12135 	was visible with size = 0 and could be visible near overflow on the
   12136 	number of characters.
   12137 	Note: the buggy code was introduced in r5288 (2008-02-15), which fixed
   12138 	other issues with the thousands separator.
   12139 
   12140 	[tests/tsprintf.c] Do more tests in the da_DK locale (these are the
   12141 	only tests for which the thousands separator is not empty).
   12142 
   12143 	[tests/tsprintf.c] Do more tests involving check_sprintf() in a loop
   12144 	(to test mpfr_snprintf with size = 0 more often), and call mixed()
   12145 	later in order to get failures without the use of %n first.
   12146 
   12147 2017-05-19  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   12148 
   12149 	get rid of computations with 'double' in mpfr_zeta
   12150 
   12151 2017-05-19  Vincent Lefvre  <vincent (a] vinc17.net>
   12152 
   12153 	[tests/tsprintf.c] Added a TODO about %n test.
   12154 
   12155 	[doc/README.dev] Added MPFR_TESTS_FPE_TRAP documentation.
   12156 
   12157 	[tests/tests.c] Corrected comment about MPFR_TESTS_FPE_TRAP.
   12158 
   12159 	Renamed MPFR_TESTS_DIVBYZERO to MPFR_TESTS_FPE_DIV (less confusing).
   12160 	In doc/README.dev, updated the corresponding description.
   12161 
   12162 	[tests] Renamed MPFR_RAISE_EXCEPTIONS to MPFR_TESTS_FPE_TRAP.
   12163 
   12164 	[tests] Got rid of MPFR_TESTS_EXCEPTIONS (added in r11489 and above),
   12165 	which is redundant with MPFR_TESTS_DIVBYZERO and MPFR_ERRDIVZERO. The
   12166 	code related to these exceptions is now like r11488 (see the output of
   12167 	"svn diff -r11488"), but keeping the following changes:
   12168 	  * Missing !defined(MPFR_ERRDIVZERO) tests added in r11498,11499.
   12169 	  * In tests.c:
   12170 	      - code related to traps (macro MPFR_RAISE_EXCEPTIONS, which will
   12171 	        be renamed);
   12172 	      - more detailed output about which FP exceptions occurred;
   12173 	      - removal of "#ifdef MPFR_ERRDIVZERO" (as in r11493), as this is
   12174 	        better with Automake 1.13+ (required by MPFR since r9375).
   12175 	Note: EXCEPTIONS_FLAG renamed to FPE_FLAGS, since EXCEPTIONS_FLAG is
   12176 	reserved by ISO C when <errno.h> is included.
   12177 
   12178 	[tests/tsprintf.c] Do the locale_da_DK() test several times to yield
   12179 	a failure by default once the bug triggered by mixed() is fixed.
   12180 
   12181 	[tests/tsprintf.c] Updated comment about r11501: the failure occurs
   12182 	with %n when the size argument of mpfr_vsnprintf is 0.
   12183 
   12184 	[tests/tsprintf.c] Do more tests with %n. One now gets a failure
   12185 	by default (which occurs when one gets randsize <= 0).
   12186 
   12187 	[tests/tsprintf.c] Fixed portability issues: The va_end(3) man page
   12188 	of Linux Programmer's Manual says: "On some systems, va_end contains
   12189 	a closing '}' matching a '{' in va_start, so that both macros must
   12190 	occur in the same function, and in a way that allows this."
   12191 
   12192 	[tests/tget_set_d64.c] Disable tests with a division by 0 (which now
   12193 	occurs only with -DXDEBUG) if MPFR_ERRDIVZERO is defined.
   12194 
   12195 	[tests/tset_ld.c] Disable an overflow test with a division by 0
   12196 	(now occurs only with -DXDEBUG) if MPFR_ERRDIVZERO is defined.
   12197 
   12198 	[doc/README.dev] Details for "-DMPFR_TESTS_DIVBYZERO -DMPFR_ERRDIVZERO".
   12199 
   12200 	[tests/tsprintf.c] In mixed(), initialize n2 to an invalid value
   12201 	in order to ease failure analysis.
   12202 
   12203 2017-05-19  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   12204 
   12205 	removed leftover debug statement in last commit
   12206 
   12207 	fix for clang bug (https://bugs.llvm.org//show_bug.cgi?id=17686)
   12208 
   12209 2017-05-19  Vincent Lefvre  <vincent (a] vinc17.net>
   12210 
   12211 	[tests/tests.c] Change for MPFR_TESTS_DIVBYZERO: in case of FE_DIVBYZERO
   12212 	or FE_INVALID, fail unconditionally, not just when MPFR_ERRDIVZERO is
   12213 	defined, otherwise one cannot see the output about the floating-point
   12214 	exceptions with "make check" (the test of MPFR_ERRDIVZERO here should
   12215 	have been removed after switching to Automake 1.13, which discards the
   12216 	output when the test program succeeds).
   12217 	Note: defining MPFR_TESTS_DIVBYZERO without MPFR_ERRDIVZERO is just for
   12218 	debugging.
   12219 
   12220 2017-05-19  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   12221 
   12222 	more work on MPFR_TESTS_EXCEPTIONS
   12223 
   12224 2017-05-19  Vincent Lefvre  <vincent (a] vinc17.net>
   12225 
   12226 	[tests/tests.c] Re-added code testing FE_DIVBYZERO and FE_INVALID with
   12227 	-DMPFR_TESTS_DIVBYZERO -DMPFR_ERRDIVZERO, because MPFR_TESTS_EXCEPTIONS
   12228 	is not ready yet.
   12229 
   12230 	[tests/tversion.c] Output IEEE floats status.
   12231 
   12232 2017-05-19  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   12233 
   12234 	check for fp exceptions (experimental)
   12235 
   12236 2017-05-17  Vincent Lefvre  <vincent (a] vinc17.net>
   12237 
   12238 	[src/cmp2.c] Added/updated comments.
   12239 
   12240 	[tests/tcmp2.c] Added tests with equal numbers, possibly of different
   12241 	sizes.
   12242 
   12243 	[src/cmp2.c] Corrected comments.
   12244 
   12245 	[tools/mpfrlint] In the detection of reserved macro names, skip ERR
   12246 	from src/mpfr-gmp.h (this is a special case).
   12247 
   12248 	[tests/tget_set_d64.c] Made PRINT_ERR_MISC more robust.
   12249 
   12250 	[tests/*.c] Renamed the remaining macros whose names are reserved
   12251 	by ISO C when <errno.h> is included.
   12252 
   12253 2017-05-16  Vincent Lefvre  <vincent (a] vinc17.net>
   12254 
   12255 	[tests/texceptions.c] Made code formatting consistent.
   12256 
   12257 	[tests/*.c] Renamed "ERROR" macro (macro name reserved by ISO C
   12258 	when <errno.h> is included) to "PRINT_ERROR", and made the macro
   12259 	more robust.
   12260 
   12261 	Define the EXP() macro in src/mpfr-gmp.h only when needed (macro name
   12262 	reserved by ISO C when <errno.h> is included).
   12263 
   12264 	[src/gamma.c] Got rid of the EXPM1_STR macro (macro name reserved
   12265 	by ISO C when <errno.h> is included), made no longer interesting by
   12266 	using mpfr_set_str_binary only once and another temporary variable.
   12267 	At the same time, replaced the usual allocation by a GROUP allocation
   12268 	(more efficient).
   12269 
   12270 2017-05-15  Vincent Lefvre  <vincent (a] vinc17.net>
   12271 
   12272 	[tests/tcheck.c] Code reformatting (GNU coding style).
   12273 
   12274 	[tests/tcheck.c] Renamed "ERROR" macro (macro name reserved by ISO C
   12275 	when <errno.h> is included) to "PRINT_ERROR".
   12276 
   12277 	Do not define macro names starting with "SIG" (+ uppercase letter)
   12278 	as they are reserved when <signal.h> is included (ISO C, 7.31.7),
   12279 	which happens to be the case in tests/tests.c, which also includes
   12280 	tests/mpfr-test.h and src/mpfr-impl.h indirectly.
   12281 	  * src/mpfr-impl.h, tests/mpfr-test.h: renamed macros:
   12282 	      SIGN  VSIGN
   12283 	      SIGN_RAND  RAND_SIGN
   12284 	  * {src,tests}/*.{c,h}: updated the names in the use of these macros.
   12285 
   12286 	[tools/mpfrlint] Added a comment about the definition of reserved
   12287 	identifiers (in particular, macro names).
   12288 
   12289 	[tools/mpfrlint] Detect the definition of reserved macro names.
   12290 
   12291 	[src/bernoulli.c] Changed isprime to is_prime in order to avoid obscure
   12292 	problems if <ctype.h> is added to mpfr-impl.h in the future (or if this
   12293 	function is made external). See ISO C "Future library directions",
   12294 	Clause 7.31.2 "Character handling <ctype.h>".
   12295 
   12296 2017-05-12  Vincent Lefvre  <vincent (a] vinc17.net>
   12297 
   12298 	[src/mpfr-impl.h] Improved comments about assertions and MPFR_ASSUME().
   12299 
   12300 2017-05-09  Vincent Lefvre  <vincent (a] vinc17.net>
   12301 
   12302 	[INSTALL] Mention the problem when almost all the tests fails with a
   12303 	message "Incorrect MPFR version! ...".
   12304 
   12305 	Increase the buffer sizes even more, and added a comment. This may
   12306 	be better in case of quick future changes (possibly for debugging),
   12307 	without checking carefully. For the tests, optimal code is useless.
   12308 
   12309 2017-05-09  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   12310 
   12311 	fixed bugs found by gcc 7.1.0 (-Werror=format-overflow=)
   12312 	[VL] The MPFR code was correct. This is actually a bug in GCC:
   12313 	  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79257
   12314 
   12315 2017-05-09  Vincent Lefvre  <vincent (a] vinc17.net>
   12316 
   12317 	[doc] Updated FAQ.html with update-faq.
   12318 
   12319 2017-05-05  Vincent Lefvre  <vincent (a] vinc17.net>
   12320 
   12321 	[tools/mbench/timp.h] Updated TIMP_MEASURE() to handle the case where
   12322 	the return value is 0: this probably means that timp_overhead was too
   12323 	large and incorrect. In this case, TIMP_OVERHEAD() is called again to
   12324 	recompute timp_overhead and the timing is redone.
   12325 	Note: if we do not call TIMP_OVERHEAD() again, then TIMP_MEASURE()
   12326 	loops indefinitely, meaning that timp_overhead was really too large.
   12327 
   12328 	[tools/mbench/timp.h] Comment at the wrong place. Fixed.
   12329 
   12330 	[tools/mbench/timp.h] Added a comment about r11458.
   12331 
   12332 2017-05-04  Vincent Lefvre  <vincent (a] vinc17.net>
   12333 
   12334 	[tools/mbench/timp.h] Fixed overflows on unsigned arithmetic.
   12335 
   12336 	[tools/mbench/mfv5.h] Increased values from 2^60-1 to 2^64-1
   12337 	(it is possible to get more than 2^60-1 cycles in practice!).
   12338 
   12339 	Merged the latest changes from the trunk, including some old changesets
   12340 	related to mpfr_zeta that were skipped, resolving conflicts. Added RNDF
   12341 	support to new code introduced by this merge:

   12350 	    in similar existing special code (mpfr_add1sp1 and mpfr_add1sp2).
   12351 	  * In mpfr_add1sp3, do the same thing (this should have been done in

   12353 	  * About r11279 (src/sub1sp.c, tests/tsub1sp.c), which introduces new

   12355 	    In tests/tsub1sp.c, s/RND_LOOP/RND_LOOP_NO_RNDF/ as usual to avoid
   12356 	    a failure.
   12357 	  * Note: concerning mpfr_sub1sp3, RNDF support was added at the same
   12358 	    time of the merge in r11179.
   12359 	  * Some style changes related to RNDF, in particular for consistency.
   12360

   12430 
   12431 	[tests/tsprintf.c] Added a test that fails on 64-bit machines

   12868 	the 32-bit Linux/x86 ABI, but now on the new precondition instead of

   13122 	[src/sub1sp.c] Added alternate code (enabled with -DMPFR_FULLSUB, until

   13124 	recognized by GCC and Clang.

   13132 
   13133 	[src/invert_limb.h] Just like for invsqrt_limb.h (r11210), in 1UL << 60,
   13134 	replaced 1UL by MPFR_LIMB_ONE to make the code valid with 32-bit long.
   13135 
   13136 	[src/invsqrt_limb.h] Bug fix: replaced 1UL by MPFR_LIMB_ONE since the
   13137 	computations are done on limbs, which are expected to have 64 bits in
   13138 	this context (the old code would fail on MS Windows / MinGW, where limbs
   13139 	are 64-bit unsigned long long and unsigned long is a 32-bit type).

   13159 	Note: I had to modify the patch to use quadrigraphs, otherwise the

   13170 2017-01-13  Vincent Lefvre  <vincent (a] vinc17.net>
   13171 
   13172 	[src/invert_limb.h] Fit on 80 columns (one line was over the
   13173 	POSIX line-length limit of 2047 characters).
   13174 
   13175 	[src/invert_limb.h] Correction in __gmpfr_invert_limb for 32-bit ABI:
   13176 	_d was used before being defined.
   13177 
   13178 2017-01-13  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   13184 	[src/add1sp.c] Improved a line based on analysis (+ timings I've done
   13185 	on x86_64 with GCC and Clang give better results, though they cannot
   13186 	be conclusive since the gain is too small compared to other possible
   13187 	causes of variations).
   13188 
   13189 	[tools/mbench/Makefile] Added -static to CFLAGS in order to avoid
   13190 	a link error when MPFR has been built with Clang (linking is done
   13191 	with .a libraries, i.e. static libraries).
   13192 
   13193 	[src/add1sp.c] Replaced "return 0;" by "MPFR_RET(0);" to emphasize on
   13194 	the fact that we return a ternary value (code instrumentation may also
   13195 	be easier later). Note: this is equivalent since the macro expands to
   13196 	0 != 0 ? ... : 0, which gives 0 via trivial optimization.
   13197 
   13198 	[src/add1sp.c] Improvements in mpfr_add1sp1; added a TODO.
   13199 	Note for rb -> bp[0]: the generated code is the same, but the source
   13200 	is more readable (-> rb has only one meaning).
   13201 
   13202 	[src/div.c] C90 compatibility (avoid initializer elements not computable
   13203 	at load time).

   13211 	and replaced MPN_COPY_INCR/MPN_COPY_DECR by mpn_copyi/mpn_copyd
   13212 
   13213 	[src/div.c] small improvement in div_1 and div_2: force all precisions to be
   13214 		    equal, then we cannot have rb <> 0 and sb = 0

   13242 	    in C (to make the compiler understand the code).
   13243 	  * src/mpfr-impl.h: added ADD_LIMB macro (addition with carry).

   13494 
   13495 	[mpfr.texi] Be stronger in mpfr_round_nearest_away documentation

   13509 
   13510 	[src/log.c] Slight simplification / improvement.
   13511 
   13512 	[doc/algorithms.tex] In Section "The logarithm function" (from r9046),
   13513 	removed everything concerning the AGM since this is not what is done
   13514 	in the MPFR code, where mpfr_agm is simply called (and this function
   13515 	already has its own description later).
   13516 	Note: The error analysis of mpfr_log can only be found in log.c, but
   13517 	seems incorrect (though the bounds may be valid); it was introduced
   13518 	in r416.

   13534 	[doc/sum.txt] Update for faithful rounding (MPFR_RNDF).
   13535 
   13536 	[src/sum.c] Fixed the bug mentioned in r11077.
   13537 
   13538 	[tests/tsum.c] The new test for MPFR_RNDF in r11079 can actually trigger
   13539 	a failure; increased the number of tests to get a failure by default.
   13540 
   13541 	[tests/tsum.c] Improved a test to support MPFR_RNDF. It doesn't fail,
   13542 	but would if 0 in "corr = 0" were changed to -1 or 1 (tested).
   13543 
   13544 	Removed trailing spaces.
   13545 
   13546 	[src/sum.c] Improvement for MPFR_RNDF, but still based on the change
   13547 	done in r10512, which was incorrect; added a FIXME (a non-regression
   13548 	test needs to be added first).
   13549 
   13550 	Merged the latest changes from the trunk (this concerns only src/sum.c
   13551 	and will be useful for the upcoming improvement).
   13552 
   13553 	[src/sum.c] Delay some assignments so that they are done just before
   13554 	the variables are used (this should have been done in r10467).
   13555 
   13556 	Merged the latest changes from the trunk.
   13557 
   13558 	[doc/mpfr.texi] For mpfr_get_str, explicitly say that the inexact flag
   13559 	is set iff the result is inexact (since this may not be obvious and this
   13560 	wasn't the case until now). In the compatibility section, mention this
   13561 	change.
   13562 
   13563 	[doc/mpfr.texi] For mpfr_get_str, removed the note saying that
   13564 	the inexact flag is not set when the conversion is inexact:
   13565 	this is fixed in r11071.
   13566 
   13567 	[src/get_str.c] Corrected a comment and a test for inexactness
   13568 	( the new tget_str.c test no longer fails).

   13575 
   13576 	[tests/tstrtofr.c] Replaced mpfr_cmp() == 0 by mpfr_equal_p().
   13577 
   13578 	[doc/mpfr.texi] Updated the month.
   13579 
   13580 	[src/get_str.c] Removed an obsolete comment, which came from r2757
   13581 	(and even before, under another form); this comment no longer made
   13582 	any sense as the sign of dir is no longer tested.
   13583 
   13584 	[src/get_str.c] Indentation fixed.
   13585 
   13586 	[src/get_str.c] Setting the inexact flag as done in r11060 was incorrect
   13587 	since the flags are restored. Moreover, this was done even when the Ziv
   13588 	loop was going to fail (it's not clear whether this was expected). Moved
   13589 	the test out of the Ziv loop, and update the copy of the flags instead
   13590 	of the flags that will be overwritten.
   13591 	Note: this still fails, but now for another reason.
   13592 
   13593 	[tests/tget_str.c] Check the inexact flag for mpfr_get_str.

   13858 2016-11-29  Vincent Lefvre  <vincent (a] vinc17.net>
   13859 
   13860 	Check that the numberof() macro is used on an array.
   13861 	  * src/mpfr-gmp.h: define numberof_const() macro, equivalent to the
   13862 	    old numberof() macro: no check, but constant expression; improved
   13863 	    the numberof() macro to check that it is used on an array (since
   13864 	    an array can silently be converted to a pointer in C). Note that
   13865 	    potential failures are currently reported at run time.
   13866 	  * src/mulders.c: replaced numberof by numberof_const in #define's
   13867 	    (also removed a useless cast at the same time).
   13868 
   13869 2016-11-17  Vincent Lefvre  <vincent (a] vinc17.net>
   13870

   13875 
   13876 	[tests/tset_ld.c] Added an overflow test that triggers a bug for
   13877 	double-double (IBM long double format). See:
   13878 	  https://sympa.inria.fr/sympa/arc/mpfr/2016-11/msg00006.html
   13879 
   13880 	[src/get_ld.c] Fixed bugs for double-double (IBM long double format):
   13881 	  * one from r8650, which could yield a spurious assertion failure
   13882 	    in debug mode in case of underflow (with result 0);
   13883 	  * one from r8972, which used the variable sign uninitialized and
   13884 	    could yield a result with an incorrect sign.
   13885 
   13886 	[tests/tset_ld.c] Added a missing exit(1).
   13887 
   13888 	[tests] _GMP_IEEE_FLOATS was got rid of in r10150, but still used in
   13889 	the tests, meaning that some tests were no longer done. So, get rid of
   13890 	_GMP_IEEE_FLOATS also in the tests. Testing !defined(MPFR_ERRDIVZERO)
   13891 	or defined(HAVE_SIGNEDZ) should be sufficient, depending on the context
   13892 	(they were already used alone at some other places, so that new failures
   13893 	are unlikely); anyway, _GMP_IEEE_FLOATS was not the right macro to test.
   13894 	Only tget_set_d64.c has a specific change to use _MPFR_IEEE_FLOATS.
   13895 
   13896 	[src/get_ld.c] For double-double (IBM long double format): test other
   13897 	special values, as this may be useful.
   13898 
   13899 	[src/get_ld.c] For double-double (IBM long double format), the code
   13900 	was incorrect on large finite values, which are infinite as a double:
   13901 	(+inf) + (-inf) was computed, which is NaN (thanks to Rob for the
   13902 	report). Fixed this bug, with code clean up (not tested).
   13903 
   13904 2016-11-10  Vincent Lefvre  <vincent (a] vinc17.net>
   13905

   13920 
   13921 	[doc/sum.txt] Improved an example (from my ARITH-23 slides).
   13922 
   13923 	[doc/sum.txt] English usage.
   13924 
   13925 2016-11-07  Vincent Lefvre  <vincent (a] vinc17.net>
   13926 
   13927 	[doc/sum.txt] Explained the handling of halfway cases for sq = 1
   13928 	(since the explanations for sq  2 are not valid for sq = 1).
   13929 
   13930 	[doc/sum.txt] Minor update.
   13931 
   13932 	[doc/sum.txt] Last corrections. Concerning the setting of the sign of
   13933 	the result, this changed with the support for precision 1 (see r10068).
   13934 
   13935 	[doc/sum.txt] Correction (English).
   13936 
   13937 	[doc/sum.txt] Correction about neg / sgn.
   13938 
   13939 	[doc/sum.txt] Added details about the handling of halfway cases, as
   13940 	the rule is not obvious due to two's complement representation.
   13941 
   13942 2016-11-06  Vincent Lefvre  <vincent (a] vinc17.net>
   13943

   13947 
   13948 2016-11-04  Vincent Lefvre  <vincent (a] vinc17.net>
   13949 
   13950 	[doc/sum.txt] A bit more explanations.
   13951 
   13952 	[doc/sum.txt] Corrected the usage of the HYPHEN-MINUS character (-):
   13953 	  * If it is a minus sign, use U+2212 MINUS SIGN (as already done).
   13954 	  * Do not use "-" after the "non" and "pre" prefixes.
   13955 
   13956 	[doc/sum.txt] Minor improvement.

   13965 	some other improvements.
   13966 
   13967 	[doc/sum.txt] Corrected 2 typos.
   13968 
   13969 	[src/sum.c] Changed a MPN_COPY_DECR to MPN_COPY, which may be more
   13970 	efficient: as of r10464 (support for reused arguments), the memory
   13971 	used by the accumulator for the TMD resolution is no longer a part
   13972 	of the main accumulator, so that we now know that the memory blocks
   13973 	do not overlap.

   13992 	  * Increased the use of macros to avoid some code duplication
   13993 	    (with risks of typos) and to prevent the problems related
   13994 	    to thread-safe DLL from appearing in the .c files.
   13995 	  * The prototypes of the functions to access the address of a

   14026 	[src]
   14027 	  * mpfr-impl.h: document the memory allocated for a significand;
   14028 	    added a cast to avoid a direct conversion from mp_limb_t * to
   14029 	    mp_size_t *.
   14030 	  * init2.c, round_prec.c, set_prec.c: code clean-up by correcting
   14031 	    the type expected for the second argument of MPFR_SET_MANT_PTR
   14032 	    (this macro has a cast, so that this should not change anything,
   14033 	    but the old type mpfr_limb_ptr was meaningless and confusing).

   14156 	[tests/tset_ld.c] Fixed print_binary.
   14157 
   14158 	[tests/tset_ld.c] Added a FIXME in print_binary, which can yield an
   14159 	incorrect output and return a wrong precision (causing the failure).
   14160 
   14161 	[tests/tset_ld.c] Added a test that triggers a failure with gcc -mpc64
   14162 	on x86 (64-bit ABI).

   14166 
   14167 	[tests/tset_ld.c] In print_binary, added an assertion that may fail
   14168 	with flush-to-zero on underflow (avoiding an infinite loop).
   14169 
   14170 	[tests/tset_ld.c] Simplified a condition in print_binary (BTW, the old
   14171 	condition was based on the fact that the rounding depended only on the
   14172 	exact result, which may not be the case when rounding is not completely
   14173 	specified, e.g. with double-double arithmetic like on PowerPC).
   14174 
   14175 	[tests/tset_ld.c] Replaced a condition by a simpler, equivalent one.

   14258 
   14259 	[src/get_ld.c] Improved the fix done in r10808: The mpfr_set_emin value
   14260 	is not changed, but let's make the LDBL_MIN_EXP and LDBL_MAX_EXP values
   14261 	appear as expected.
   14262 	Note: The code for x86 extended precision first appeared in r3226 with
   14263 	the usual emin and emax values, as found in the IEEE 754-1985 standard
   14264 	(bounds) or on <https://en.wikipedia.org/wiki/IEEE_floating_point>. But
   14265 	MPFR uses a different convention, with a significand between 1/2 and 1
   14266 	instead of between 1 and 2, so that these values were off by 1. The
   14267 	emax one was fixed in r6101, but the error on emin remained undetected.
   14268 
   14269 	[tests/tset_ld.c] The bug_20160907 test is valid only with

   14329 
   14330 	[TODO] Updated item on tzeta:

   14332 	    for r9954 are different is normal (fixes in mpfr_can_round affecting
   14333 	    tgeneric.c), and the timings depend on GMP_CHECK_RANDOMIZE and seem
   14334 	    equivalent in average with "test_generic (..., 5);" in both cases;
   14335 	  * added the fact that tzeta has been much slower since r9848, at least
   14336 	    with the x86 32-bit ABI.

   14494 
   14495 	[src/round_prec.c] Various corrections/improvements:
   14496 	  * Unified the return, making sure that temporary memory is no longer
   14497 	    used after MPFR_TMP_FREE(marker), which was not the case in some
   14498 	    places.
   14499 	  * C90 compatibility.
   14500 	  * Minor improvements (use of MPFR_PREC2LIMBS, code on 78 columns...).
   14501 
   14502 	[TODO] Added: unify is_power_of_two() and mpfr_powerof2_raw()?
   14503 
   14504 	[src/atan2.c] Replaced the use of the MPFR_IS_POWER_OF_2(x) macro by
   14505 	  a more efficient solution based on mpfr_powerof2_raw().
   14506 	[src/mpfr-impl.h] Removed the now obsolete MPFR_IS_POWER_OF_2 macro.
   14507 
   14508 2016-08-26  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   14509 
   14510 	[src/mpfr-gmp.h] added comment about GMP memory allocation functions
   14511 
   14512 2016-08-25  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   14513 
   14514 	[src/round_p.c] since mpfr_can_round is now always correct, we cannot compare
   14515 			it blindly to mpfr_round_p any more
   14516 
   14517 2016-08-24  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   14518 
   14519 	[src/round_prec.c] fixed mpfr_can_round() so that all tests of tcan_round pass
   14520 
   14521 2016-08-23  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   14522 
   14523 	[tests/tcan_round.c] more information in case of error in check_can_round()
   14524 
   14525 2016-08-22  Vincent Lefvre  <vincent (a] vinc17.net>
   14526 
   14527 	[tools/mbench/mfv5.cc] Fixed code (C++11 compatibility).
   14528 
   14529 	[tests/tcan_round.c] Added a comprehensive test of mpfr_can_round,
   14530 	based on a naive implementation.
   14531 	Note: if the exit() is removed, many cases are failing, for both kinds
   14532 	of answers (there might also remain an error in my test...).
   14533 
   14534 2016-08-19  Vincent Lefvre  <vincent (a] vinc17.net>
   14535 
   14536 	[TODO] More thoughts about mpz_t caching (mpz_t pool).
   14537 
   14538 	[TODO] Issues with mpz_t caching.
   14539 
   14540 	[TODO] Update about mpz_t caching (mpz_t pool).
   14541 
   14542 	[src/atan.c] Added TODO's to use mpz_init2 instead mpz_init: I could
   14543 	check that without "mpz_t cache" (pool), this makes the code faster.
   14544 
   14545 	[doc/README.dev] Added a note about memory reallocations; recommend
   14546 	mpz_init2 with the estimated maximum size instead of mpz_init.
   14547 
   14548 	[tests/tests.c] Updated the error message on incorrect MPFR version.
   14549 
   14550 	[INSTALL] Added note on Solaris and the LD_OPTIONS environment variable.
   14551 
   14552 2016-08-11  Vincent Lefvre  <vincent (a] vinc17.net>
   14553 
   14554 	[tools/coverage] Added a warning: on a machine shared with other users,
   14555 	by running this script, the account can easily be compromised due to a
   14556 	libtool bug.
   14557 
   14558 2016-08-06  Vincent Lefvre  <vincent (a] vinc17.net>
   14559 
   14560 	[src/mpfr.h] Moved MPFR_DEPRECATED before __MPFR_DECLSPEC for
   14561 	compatibility with MSVC (and documented this requirement).
   14562 	Thanks to Brian Gladman for the information.
   14563 
   14564 2016-08-04  Vincent Lefvre  <vincent (a] vinc17.net>
   14565 
   14566 	[doc/README.dev] Added a note about the C++11 compatibility issue
   14567 	with a string literal immediately followed by a macro name.
   14568 
   14569 	Fixed remaining macros with missing "do"  "while (0)", detected with
   14570 	mpfrlint. There were no consequences except spurious null statements.
   14571 
   14572 	[tools/mpfrlint] Added a comment.
   14573 
   14574 	[tools/mpfrlint] Added a test detecting (unsafe) macros of the form:
   14575 	  #define FOO { ... }
   14576 	The following form is preferred in most of the cases to avoid spurious
   14577 	null statements:
   14578 	  #define FOO do { ... } while (0)
   14579 
   14580 	[tests/tsi_op.c] Fixed a macro. There were no consequences except
   14581 	spurious null statements.
   14582 
   14583 	[tests/tset_{si,sj}.c] Style improvements. Added a comment.
   14584 
   14585 	[tests/tset_{si,sj}.c] Fixed macros. There were no consequences except
   14586 	spurious null statements.
   14587 
   14588 	[tests] C++ compatibility: avoid errors with "g++ -std=c++11" or later.
   14589 	Note that as of GCC 6, "the default mode for C++ is now -std=gnu++14
   14590 	instead of -std=gnu++98" <https://gcc.gnu.org/gcc-6/changes.html>.
   14591 	So, this fixes the failures in the build of the MPFR tests with g++
   14592 	from GCC 6 without particular options.
   14593 
   14594 2016-08-03  Vincent Lefvre  <vincent (a] vinc17.net>
   14595 
   14596 	[src/round_prec.c] mpfr_can_round_raw: added another FIXME.
   14597 
   14598 	[src/round_prec.c] mpfr_can_round_raw: added an assertion, corrected
   14599 	a condition in a comment, and added comments, showing a new bug.
   14600 
   14601 2016-08-02  Vincent Lefvre  <vincent (a] vinc17.net>
   14602 
   14603 	[tests/tmul.c] Various corrections and improvements in test_underflow.
   14604 
   14605 	[src/mpfr.h] Mark mpfr_grandom as deprecated (this had already been done
   14606 	in mpfr.texi r8548).
   14607 
   14608 	[src/mpfr.h] Suggest MPFR_EXPERIMENTAL for experimental functions.
   14609 
   14610 2016-08-01  Vincent Lefvre  <vincent (a] vinc17.net>
   14611

   14613 
   14614 	[tests/tversion.c] Corrections in the info about the C implementation.
   14615 
   14616 	[src/sqrt.c] Corrected a bound in the proof of mpfr_sqrt1 (one-limb
   14617 	precisions), related to the right shift of a negative value. Added
   14618 	a warning and a TODO about such an operation.
   14619 
   14620 	[src/sqrt.c] Enable mpfr_sqrt1 code for one-limb precisions (which
   14621 	depends on implementation-defined features of the C standard) only
   14622 	when __GNUC__ is defined, as it is known to be correct with GCC and
   14623 	compatible compilers, but nothing is known yet for other compilers.
   14624 	Removed the corresponding FIXME and added a note. In the future, a
   14625 	configure test could be used as an alternative solution.
   14626 
   14627 	[tests/tversion.c] Output more information about the C implementation.
   14628 
   14629 2016-07-31  Vincent Lefvre  <vincent (a] vinc17.net>
   14630 
   14631 	[src/sqrt.c] Fixed some portability issues.
   14632 
   14633 	[src/sqrt.c] Fix if mp_limb_t > unsigned long (this fixed failures
   14634 	with mingw-w64).
   14635 
   14636 	[src/lngamma.c] Fix in case mp_limb_t is more than twice as large
   14637 	  as unsigned long (that would make it at least 128 bits).
   14638 	[src/cos.c] Made code similar to the rest of the code.
   14639 
   14640 	[src/div_ui.c] Improved a comment (to make it closer to what correct
   14641 	C code should be), avoiding a false positive with mpfrlint.
   14642 
   14643 	[tools/mpfrlint] Detect possibly wrong code with some C/GMP
   14644 	implementations, related to shifts and integer types.
   14645 
   14646 	[src/sqrt.c] Completed the FIXME (another portability issue).
   14647 
   14648 	[src/sqrt.c] Added a FIXME. The current code for prec < GMP_NUMB_BITS
   14649 	is not portable.
   14650 
   14651 	[src/sqrt.c] Fixed code for implementations with 16-bit int's.
   14652 
   14653 	[tests/tsqrt.c] Fixed output bug in a test.

   14711 
   14712 	[src/round_prec.c] Various minor improvements:
   14713 	  * Added a MPFR_ASSERTN since mpfr_can_round is a function in the API.
   14714 	  * Changed error variables to be more consistent with the context.
   14715 	  * Removed unnecessary code (casts...) about the error: it came from
   14716 	    round.c r1574, where types were different at that time.
   14717 	  * Made err2 (the old err) local to a small block to make sure that it
   14718 	    will not be used by mistake instead of err in future changes.
   14719 	  * Made equivalent expressions appear under the same form:
   14720 	      (rnd1 == rnd2 || rnd2 == MPFR_RNDN) && err - 2 >= prec
   14721 
   14722 	[src/round_prec.c] Changed precision variables to be like SSA.

   14727 	[src/round_prec.c] Removed useless parentheses.
   14728 
   14729 	[src/round_prec.c] Added an assertion for "default:".
   14730 
   14731 	[tests/tcan_round.c] In test_simple, output p (which is variable),
   14732 	not prec (which is always 4).

   14743 
   14744 	[tests/tgeneric.c] Improvement: When the result is exact, it can always

   14768 
   14769 	[TODO] Added item about the fix of mpfr_can_round in r9883 and tzeta.
   14770 
   14771 	New MPFR_GENERIC_ABI macro to test the generic code, not tied to a
   14772 	particular ABI (e.g. GMP_NUMB_BITS value), so that such code has a
   14773 	chance to be tested on current machines.
   14774 	  * doc/README.dev: added brief documentation.
   14775 	  * src/sqrt.c: enable mpfr_sqrt1 (optimization for one-limb precisions,
   14776 	    currently when GMP_NUMB_BITS is 32 or 64) only when MPFR_GENERIC_ABI
   14777 	    is not defined.
   14778 
   14779 	[src/sqrt.c]
   14780 	  * Changed mp_ptr to mpfr_limb_ptr.

   14816 
   14817 	Merged r10657 from the trunk, resolving the conflict (same code as
   14818 	in the trunk, except RND_RAND changed to RND_RAND_NO_RNDF).
   14819 
   14820 	[tests/tadd.c] Improved coding style and messages (do not mix up
   14821 	"inexact flag" and "ternary value"!).
   14822 
   14823 	[tests] Define the RND_RAND_NO_RNDF and RND_LOOP_NO_RNDF macros, similar
   14824 	to RND_RAND and RND_LOOP respectively but excluding MPFR_RNDF, to be
   14825 	used for tests that don't make sense in the faithful rounding mode.
   14826 	Replaced code to use these macros, fixing the remaining failures.
   14827 
   14828 	Merged r10599 through r10628 from the trunk, resolving the conflict
   14829 	in tests/tmul.c (i.e. keep code from both the branch and the trunk,
   14830 	corresponding to two independent tests). Some of the later changes
   14831 	in the trunk (src/sqrt.c) are broken with a 32-bit ABI, so let's not
   14832 	merge them for now.
   14833 
   14834 	Merged r10598 from the trunk, resolving the conflict (this consists
   14835 	in changing MPFR_PREC to MPFR_GET_PREC).

   15217 
   15218 	Renamed macro MPFR_EXP_LESS_P to MPFR_UBF_EXP_LESS_P.
   15219 
   15220 	[src/add1sp.c] Fixed bug introduced in r10530 when MPFR_WANT_ASSERT >= 2
   15221 	(--enable-assert=full).
   15222 
   15223 	[src/add1.c] Re-added the MPFR_ASSERTD. The culprit seems to be r10530.
   15224 
   15225 	[src/add1.c] Reverted r10529, which now fails. That's strange.

   15235 2016-06-29  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   15236 
   15237 	still faster code for 1 limb
   15238 
   15239 	merged r10522 from faithful branch + other special-code for 1 limb:
   15240 	the worst case for mpfr_add in 53 limbs decreases from 70 to 60 cycles
   15241 
   15242 	removed leftover debug statement
   15243 
   15244 	added comment that EXP(b) >= EXP(c)
   15245 
   15246 	mpfr_add1sp no longer assumes EXP(b) >= EXP(c): gives small speedup

   15253

   15265 
   15266 	[src/vasprintf.c] Some improvements. In particular, avoid two successive
   15267 	calls to mpfr_cmpabs on the same arguments (the compiler doesn't know
   15268 	that it could optimize, as the function is not pure).
   15269 
   15270 	[src/vasprintf.c] Fixed an assertion failure.
   15271 
   15272 2016-06-24  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   15279 
   15280 	[tests/tsum.c] Correction: r10484 didn't take the latest version from
   15281 	the trunk in the conflict resolution.
   15282 
   15283 	[src/sum.c] A more efficient way to support faithful rounding, avoiding
   15284 	the TMD completely and an assertion failure at the same time.
   15285 
   15286 	Avoid failures in mpfr_mul for MPFR_RNDF with MPFR_WANT_ASSERT >= 2
   15287 	(--enable-assert=full) by disabling the comparison with the old
   15288 	implementation, which doesn't make sense for faithful rounding.
   15289 
   15290 2016-06-24  Vincent Lefvre  <vincent (a] vinc17.net>
   15291 
   15292 	Avoid failures in mpfr_add1sp / mpfr_sub1sp for MPFR_RNDF with
   15293 	MPFR_WANT_ASSERT >= 2 (--enable-assert=full) by disabling the
   15294 	comparison with mpfr_add1 / mpfr_sub1, which doesn't make sense
   15295 	for faithful rounding.
   15296 
   15297 	[Added during the Subversion to Git conversion]
   15298 	This commit includes a merge of r10509 from the trunk.

   15300 2016-06-24  Vincent Lefvre  <vincent (a] vinc17.net>
   15301 
   15302 	Cosmetic change (whitespace).
   15303 
   15304 	Merged the latest changes from the trunk.
   15305 
   15306 	Removed trailing spaces.
   15307 
   15308 	[src/add1sp.c] For MPFR_WANT_ASSERT >= 2 (--enable-assert=full), test
   15309 	  the flags too and replaced "mpfr_cmp" by "! mpfr_equal_p".
   15310 	[src/sub1sp.c] Make it similar to add1sp.c for MPFR_WANT_ASSERT >= 2.
   15311 
   15312 2016-06-24  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   15313 
   15314 	use macro for the rounding mode used in the tests
   15315 
   15316 2016-06-24  Vincent Lefvre  <vincent (a] vinc17.net>
   15317 
   15318 	[doc/mpfr.texi] Updated the month.
   15319 
   15320 	[src/sum.c] Made the code a bit more natural: change of pos to neg
   15321 	(an indirect consequence of the support of reused arguments). Some
   15322 	other minor related changes.
   15323 
   15324 2016-06-24  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   15325 
   15326 	added more tests for RNDF
   15327 
   15328 2016-06-24  Vincent Lefvre  <vincent (a] vinc17.net>
   15329 
   15330 	The support of reused arguments in mpfr_sum is now complete, without
   15331 	any visible regressions in the timings (which are unfortunately too
   15332 	inaccurate to see anything).
   15333 	  * doc/mpfr.texi: removed sentences about the previous limitation.
   15334 	  * src/sum.c: removed the corresponding FIXME/TODO comment.
   15335 
   15336 	[tests/tsum.c] Test the support of reused arguments.
   15337 
   15338 2016-06-24  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   15339 
   15340 	disable mpfr_all_div() for RNDF
   15341 
   15342 	replaced mpfr_cmp by !mpfr_equal_p
   15343

   15345 
   15346 	fixed corner case with RNDF

   15348 2016-06-23  Vincent Lefvre  <vincent (a] vinc17.net>
   15349 
   15350 	[src/mpfr-impl.h] Added a comment for MPFR_RNDRAW_GEN about the use
   15351 	of the exponent field of the destination.
   15352 
   15353 	[src/add1sp.c] For MPFR_RNDF, set inexact = 0 (like what is done in
   15354 	sub1.c) instead of 1, though this doesn't really matter.
   15355 
   15356 	[src/sub1.c] Fix: the conflict resolution done in r10484 was incorrect.
   15357 
   15358 	[src/add1sp.c] Avoid the use of uninitialized values with MPFR_RNDF.
   15359 
   15360 2016-06-23  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   15361

   15364 2016-06-23  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   15365 
   15366 	merged changed from trunk with
   15367 
   15368 	  svn merge '^/trunk'
   15369 
   15370 	(resolved conflict for sub1.c; copied tests/tsum.c from trunk and

   15376 
   15377 	src/li2.c: revision 10379 was ok
   15378 
   15379 	fixed mpfr_all_div() for RNDF
   15380 
   15381 2016-06-22  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   15382 
   15383 	more work on branch faithful
   15384 
   15385 2016-06-17  Vincent Lefvre  <vincent (a] vinc17.net>
   15386 
   15387 	[src/mpfr.h] Coding style: added spaces.
   15388 
   15389 	[TODO] Suggest the use the keyword "static" in array indices of
   15390 	parameter declarations with C99 compilers (6.7.5.3p7) when the

   15397 2016-06-13  Vincent Lefvre  <vincent (a] vinc17.net>
   15398 
   15399 	[src/sum.c] Copy the significand to the destination after resolving
   15400 	the TMD in order to support reused arguments.
   15401 
   15402 	[src/sum.c] Improved a comment.
   15403 
   15404 2016-06-10  Vincent Lefvre  <vincent (a] vinc17.net>
   15405 
   15406 	[src/sum.c] Corrected a MPFR_LOG_MSG modified in the latest change.
   15407 
   15408 	[src/sum.c] For the future support of reused arguments: TMD resolution
   15409 	is now done in a specific TMD accumulator, allocated at the same time
   15410 	as the main accumulator. This TMD accumulator currently just takes at
   15411 	most 2 limbs in practice, so that's not a problem.
   15412 	[doc/sum.txt] Added TODO for things that will change.
   15413 
   15414 2016-06-09  Vincent Lefvre  <vincent (a] vinc17.net>
   15415 
   15416 	[src/mpfr-impl.h] Define mpfr_ueexp_t (needed for r10462).
   15417 
   15418 	[tests/tversion.c] Do not use "%zu" with printf (added in r10460).
   15419 
   15420 	[doc/README.dev] Document environment variables that affect the tests.
   15421 
   15422 	Other changes concerning the memory limit for the tests.
   15423 	  * Export the tests_memory_limit variable so that it can be accessed in
   15424 	    test programs (e.g. read by tversion as mentioned below, or modified
   15425 	    by a test program when executed with particular arguments).
   15426 	  * In tversion, print a warning when the memory limit has been modified
   15427 	    (with the MPFR_TESTS_MEMORY_LIMIT environment variable).
   15428 
   15429 	[tests/memory.c] The MPFR_TESTS_MEMORY_LIMIT environment variable can
   15430 	now contain an integer specifying the memory limit for the tests, or 0
   15431 	for unlimited, the default still being 2^22 = 4 MB.
   15432 
   15433 2016-06-08  Vincent Lefvre  <vincent (a] vinc17.net>
   15434 
   15435 	[tests/tsum.c] Improved check3:
   15436 	  * Also do the tests with output precision MPFR_PREC_MIN;
   15437 	    this completes the value coverage for tsum.
   15438 	  * Also compare the flags.
   15439 
   15440 	Value coverage for tsum: After r9984 to differentiate sq > MPFR_PREC_MIN
   15441 	and sq == MPFR_PREC_MIN, 42 tests were not done for sq == MPFR_PREC_MIN
   15442 	on a 64-bit machine. In the check4 test, changed a 2 to MPFR_PREC_MIN.
   15443 	This reduces to 12 tests that are not done.
   15444 
   15445 2016-06-07  Vincent Lefvre  <vincent (a] vinc17.net>
   15446 
   15447 	Merged the "ubf" branch into the trunk:
   15448 	  * limited implementation of "unbounded floats" (numbers with a mpz_t
   15449 	    exponent), which could be completed in the future, in particular to
   15450 	    handle intermediate overflows/underflows in polynomial evaluation;
   15451 	  * rewrote mpfr_fmma and mpfr_fmms to use them, and added tests;
   15452 	  * restored the MPFR 3.1- exponent range for compatibility;
   15453 	  * restored some tests that were based on this exponent range.
   15454 	The choice for the UBF implementation was to use a compatible structure:
   15455 	the same as the mpfr_t one, with an additional field at the end, used
   15456 	only when the exponent field _mpfr_exp has some special value. Thus some
   15457 	functions such as addition and subtraction just needed minor changes to
   15458 	support UBF, and no code was duplicated. This means that on MPFR numbers
   15459 	(the usual case), one has a few more tests than before, but with known
   15460 	branch probabilities. In practice, this should not be visible, at least
   15461 	in most applications. This was more or less confirmed by timings (even
   15462 	with many additions/subtractions in low precision, this was difficult
   15463 	to say, as timings were influenced by various parameters that we cannot
   15464 	control).
   15465 
   15466 	Merged the latest change from the trunk (r10452).
   15467 
   15468 	[tools/mbench/Makefile] Added multiarch support for GMP.
   15469 
   15470 	[src/mpfr-impl.h] Updated a comment (removing a FIXME).
   15471 
   15472 	Merged the latest change from the trunk (r10449).
   15473 
   15474 	[tests/tprintf.c] Removed tests of native %'g and %'f (from r8292)
   15475 	as the ' flag is an extension from Single UNIX Specification and
   15476 	in particular, they fail with MinGW under Wine.
   15477 
   15478 	Merged the latest changes from the trunk.
   15479 
   15480 	[tests/tlgamma.c] Typo in comment.
   15481 
   15482 	[src/uceil_log2.c] Added a comment. Cosmetic changes.
   15483 
   15484 	[tests/tlgamma.c] Corrected updated comment from r10444.
   15485 
   15486 2016-06-06  Vincent Lefvre  <vincent (a] vinc17.net>
   15487 
   15488 	[tests/tlgamma.c] Updated comment of the test added in r10442.
   15489 
   15490 	[src/uceil_log2.c] Correction in __gmpfr_ceil_log2, avoiding an
   15491 	incorrect result with tcc: x.s.exp is declared as an unsigned
   15492 	bit-field, so that tcc considers that x.s.exp - 1023 is unsigned.
   15493 	However, since all the values of x.s.exp are representable in an
   15494 	int, according to the integer promotion rules, x.s.exp should be
   15495 	converted to an int, so that the subtraction is signed. So, this
   15496 	appears to be a bug in tcc.
   15497 
   15498 	[tests/tlgamma.c] Added a test causing a "too much memory" error with
   15499 	tcc 0.9.27~git20151227.933c223-1 (there's already one in special(),
   15500 	but this one is a simpler, standalone test).
   15501 
   15502 	Merged the latest change from the trunk (r10440).
   15503 
   15504 	[acinclude.m4] When checking if __float128 is available, we now also
   15505 	check whether C99 constants (in particular the __float128 ones, such
   15506 	as 0x1.fp+16383q) are supported since this is now required with the
   15507 	__float128 support.
   15508 
   15509 	Merged the latest changes from the trunk.
   15510 
   15511 	[src/add1.c] Improved a comment about faithful rounding.
   15512 
   15513 	[src/add1.c] The code for faithful rounding (MPFR_RNDF) was not
   15514 	avoiding some useless loops needing to know on which side of a
   15515 	breakpoint the result is. Quick fix.
   15516 
   15517 	Merged the latest changes from the trunk.
   15518 
   15519 	[src/add1.c] Simplified code: removed fb = 1 since it was already 1
   15520 	in the "if (fb > 0)" branch.
   15521 
   15522 	[src/set_float128.c] Fix: removed the divisions by zero, replacing them
   15523 	by comparisons with the maximum finite binary128 number. Changes to be
   15524 	similar to the handling of infinities in "src/set_ld.c".
   15525 
   15526 	[TODO] Faithful rounding: small correction.
   15527 
   15528 	[TODO] Added "faithful rounding", with information about its definition
   15529 	and implementation.
   15530 
   15531 2016-06-03  Vincent Lefvre  <vincent (a] vinc17.net>
   15532 
   15533 	[src/{fits_intmax.c,fits_s.h}] In comments, fit  fits.
   15534 
   15535 	[src/set_float128.c] Added FIXME comment: The mpfr_set_float128 code
   15536 	generates a divide-by-zero exception. Suggest a solution.
   15537 	Note: this is detected with "-DMPFR_TESTS_DIVBYZERO -DMPFR_ERRDIVZERO".
   15538 
   15539 	[tests/tset_float128.c] Take into account failures in division by 0
   15540 	and absence of signed zeros. Also fixed the code checking the sign
   15541 	of 0 (mpfr_sgn cannot be used for that since it returns 0 for 0).

   15547 2016-06-03  Vincent Lefvre  <vincent (a] vinc17.net>
   15548 
   15549 	Merged the latest change from the trunk (r10426 fix).
   15550 
   15551 	[src/set_d.c] Added some assertions and fixed a 32-bit shift count
   15552 	when GMP_NUMB_BITS == 32.
   15553 
   15554 	Merged the latest changes from the trunk (C++ compatibility).
   15555 
   15556 	[tests/tset_float128.c] C++ compatibility.
   15557 
   15558 	[tests/tlog.c] Added a cast to mpfr_rnd_t for C++ compatibility.
   15559 
   15560 	[tests/tfmma.c] Forgot a cast to mpfr_rnd_t for C++ compatibility.
   15561 
   15562 	[src/add1.c] Completed UBF support. Note: due to the restriction
   15563 	on the exponent values, diff_exp does not need to be the unsigned
   15564 	integer type mpfr_uexp_t (mpfr_exp_t is sufficient).
   15565 
   15566 	[tests/tfmma.c] Correction.
   15567 
   15568 	[tests/tfmma.c] Test (1/2)x + (1/2)x = x near underflow.
   15569 
   15570 	[tests/tfmma.c] Replaced precision 64 by GMP_NUMB_BITS (to make sure
   15571 	that the add1sp and sub1sp conditions are satisfied with the current
   15572 	src code, these tests may rely on the fact that there are no trailing
   15573 	bits, i.e. that the precision is a multiple of GMP_NUMB_BITS).

   15575 2016-06-03  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   15576 
   15577 	added reference for Lambert W function

   15579 2016-06-03  Vincent Lefvre  <vincent (a] vinc17.net>

   15683 	      which is possible only if PREC(b) > PREC(a),
   15684 	    * c is small enough (i.e. no overlap with a and b),
   15685 	  mpfr_sub1 returns an infinity (with overflow flag set) instead of
   15686 	   the maximum number (no overflow). The cause is that an overflow
   15687 	  is generated too early, in an intermediate rounding.

   15930 
   15931 	Partly rewrote mpfr_add_ui and mpfr_sub_ui (more similar to the
   15932 	mpfr_ui_sub code), solving the failures.
   15933 
   15934 	[tests/tgeneric.c] Check NaN argument, mainly in order to check the NaN
   15935 	flag when the result is NaN (almost all cases). This makes both tadd_ui
   15936 	(ignoring the new test done in r10298) and tsub_ui fail.

   16012 
   16013 	[configure.ac] Improved the GMP CC/CFLAGS detection: the test for $cpp

   16054 	or other similar implementations. Moreover, such tests were used for
   16055 	debugging purpose or to detect potential problems in the environment,
   16056 	thus were not really useful for the end user. They were initially
   16057 	added in the win-thread-safe-dll branch (r9682, following a problem
   16058 	found in r9680). One alternative for checking by the MPFR developers

   16772 	  * Added a note about the case EXP(x) < MPFR_EMIN_MIN.
   16773 	  * Do not use the MPFR_IS_PURE_FP() macro as this macro assumes that

   16775 	    FP number (some assertion checking may be done in debug mode),
   16776 	    but this is not necessarily the case here.

   17118 	changed so that if the base precision is small (< 16), then the

   17226 
   17227 	[tests/tlog_ui.c]
   17228 	  * In the loop, do not test n = 0 and n = 1, because mpfr_can_round
   17229 	    always fails for these values, so that the test is pointless.
   17230 	  * Check that mpfr_can_round no longer fails (this is possible as
   17231 	    we are not doing random tests, i.e. the tested values are known);
   17232 	    the additional precision for y had to be increased.
   17233 	  * Also test large values of n (ULONG_MAX down to ULONG_MAX-19). When
   17234 	    GCC's run-time sanitizer -fsanitize=undefined -fno-sanitize-recover
   17235 	    is used, it signals an error for large values of n.
   17236 	  * The reference values y are obtained with mpfr_log instead of
   17237 	    mpfr_log_ui: indeed we need a different implementation from the
   17238 	    tested function, otherwise only the rounding is tested! Without
   17239 	    GCC's run-time sanitizer, this shows that mpfr_log_ui is buggy
   17240 	    for large values of n.

   17358 
   17359 	[tests/mpf_compat.h] For mpf_set_str and mpf_init_set_str, avoid strings
   17360 	with ".", since for GMP the decimal separator is locale dependent (the
   17361 	tests can be run in non-C locales on purpose in order to detect issues
   17362 	in various locales), so that for the mpf_compat test, the conversion
   17363 	fails and the mpf value x is set to 0 (which can yield other problems,
   17364 	such as with mpf_div (y, x, x), which raises an exception).
   17365 	Note: this problem appeared in r9157, where tests_start_mpfr() was added
   17366 	to mpf_compat.h (the locale setting is done in this function).

   17577 	[doc/mpfr.texi] Updated the month.
   17578 
   17579 	[doc/mpfr.texi] Changed "returned value" to "return value" when this
   17580 	is the value returned by the C function (synonymous, but sometimes
   17581 	less ambiguous).
   17582 
   17583 	[doc/mpfr.texi] For r9689, "returned value"  "return value".
   17584 
   17585 	[doc/mpfr.texi] Completed the specification of mpfr_get_{si,ui,sj,uj}

   17587 
   17588 	[tests/tget_z.c] Fixed and improved the check_one() test.
   17589 	  * The input value was modified at each iteration, giving z = 0 very
   17590 	    quickly, so that not much was tested in practice; in particular,
   17591 	    the third argument of mpz_fdiv_q_2exp in mpfr_get_z was never
   17592 	    properly tested (since it has no effect for z = 0).
   17593 	  * Added various tests of the flags.
   17594 
   17595 	[tests/tget_z.c] Optimized the check_one() test.

   17602 	+ a correction and some consistency checks. See MPFR bug 19537 on:
   17603 	https://gforge.inria.fr/tracker/index.php?func=detail&aid=19537&group_id=136&atid=619
   17604 
   17605 	[src/mpfr-impl.h] Resolved the problem under Linux.
   17606 
   17607 	[src/mpfr-impl.h] Detect some possible inconsistencies under Unix,
   17608 	when some macro should imply a MS-Windows platform.
   17609 
   17610 	Merged the latest changes from the trunk since this wasn't the cause
   17611 	of the problem.
   17612 
   17613 	Applied changes from Stephan Tolksdorf:
   17614 	  https://gforge.inria.fr/tracker/download.php/136/619/19537/4980/changes.zip
   17615 	The MPFR build fails on my Linux machine with
   17616 	  CFLAGS=-Werror=missing-prototypes
   17617 	because MPFR_WIN_THREAD_SAFE_DLL gets defined (this CFLAGS just allowed
   17618 	me to detect the problem with MPFR_WIN_THREAD_SAFE_DLL, which could have
   17619 	otherwise remained unnoticed).
   17620 
   17621 	Include config.h when need be.

   17623 2015-09-07  Vincent Lefvre  <vincent (a] vinc17.net>
   17624 
   17625 	[TODO] Updated mpz_t caching item, suggesting mpz_init2 instead.
   17626 
   17627 	[TODO] Added: check whether mpz_t caching is necessary (this was
   17628 	committed in r8911). In short, timings should be done with -static
   17629 	(this wasn't clear), they may depend on the malloc implementation,
   17630 	and after a look at the source, the difference in the timings with
   17631 	mpz_t caching is surprising and should be explained.
   17632 
   17633 2015-09-04  Vincent Lefvre  <vincent (a] vinc17.net>
   17634 
   17635 	[tools/ck-copyright-notice] Check src/mparam_h.in instead of the
   17636 	generated (and not distributed) src/mparam.h file; this is also
   17637 	useful to avoid an error after running "make tune".

   17693 
   17694 	[src/{fits_intmax.c,fits_s.h,fits_u.h}] Fixed mpfr_fits_* functions:

   17696 	fail (tests/tset_si.c r9649).
   17697 
   17698 	[tests/tset_si.c] Added mpfr_get_{si,ui} tests, including flags.

   17701 
   17702 	[src/mparam_h.in] Improved comment: __amd64__ is generic to all

   17704 	suggest to move mparam.h files to more meaningful locations.
   17705 
   17706 	[configure.ac] Added test for usability of gmp.h at link time
   17707 	(merged changeset r9644 from the 3.1 branch, with minor changes
   17708 	due to the fact that a known problem between GMP 4.1 and GCC 5

   17744 	  * Replaced each mpfr_get_exp occurrence by the internal MPFR_GET_EXP

   17747 	  * Fixed the remaining problem due to an overflow and infinite value.

   17756 
   17757 	[src/{div_2si.c,div_2ui.c,mul_2si.c}] Fixed some underflow cases in
   17758 	rounding to nearest when the exact result is -2^(emin-2), i.e. the
   17759 	middle of 0 and the minimum negative number in absolute value (the
   17760 	correction in r5517 was incorrect/incomplete).
   17761

   17824 2015-06-12  Vincent Lefvre  <vincent (a] vinc17.net>
   17825 
   17826 	[doc/faq.xsl] Remove the indent="no" to get the same behavior as before
   17827 	when using libxslt 1.1.27+. See:
   17828 	  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=718535#10
   17829 
   17830 	[tests/tfma.c] Improved the new underflow tests (test_underflow3) to
   17831 	test FMA(-x,y,-z).
   17832 
   17833 	[src/fma.c] Completely fixed the scaling in case of underflow.
   17834 
   17835 	[src/fma.c] Partially fixed the scaling in case of underflow,
   17836 	corresponding to the testcase from r9566. Double rounding is
   17837 	not handled yet (failure triggered by r9567).
   17838 
   17839 	[tests/tfma.c] Improved the new underflow tests (test_underflow3) to
   17840 	yield some cases with double rounding when scaling: If the only fix
   17841 	in src/fma.c is to change the rounding mode of the last mpfr_div_2ui
   17842 	(computing s / 2^scale) to rnd_mode, a new failure appears for n = 2,
   17843 	k = 4, s = -1, MPFR_RNDN.
   17844 
   17845 	[tests/tfma.c] Corrected the new underflow tests to really generate
   17846 	underflows, showing a bug in mpfr_fma.
   17847 
   17848 	[src/fma.c] Added log messages.
   17849 
   17850 	[tests/tfma.c] The code removed in r9560 was actually necessary,
   17851 	but do this in a better way.
   17852 
   17853 2015-06-11  Vincent Lefvre  <vincent (a] vinc17.net>
   17854 
   17855 	[tests/tfma.c] Added other underflow tests.
   17856 
   17857 	[tests/tfma.c] Some improvements.
   17858 
   17859 	[tests/tfma.c] GNU coding style.
   17860 
   17861 	[tests/tfma.c] Removed code that isn't necessary.
   17862 
   17863 	[doc/README.dev] "To make a release": mention -DMPFR_COV_CHECK and
   17864 	-DMPFR_ALLOCA_MAX=0 tests.
   17865 
   17866 2015-06-10  Vincent Lefvre  <vincent (a] vinc17.net>
   17867 
   17868 	[tests/trandom.c] Cleaner test, avoiding the explicit use of mpfr_rands.
   17869 
   17870 	[tests/trandom.c] Improved latest change, as some other test already
   17871 	assume a fixed PRNG with GMP >= 4.2.0 (now the value of the last
   17872 	random number of the test is checked).
   17873 
   17874 	[tests/trandom.c]
   17875 	  * Get a non-zero fixed-point number whose first 32 bits are 0 with the
   17876 	    default GMP PRNG. This corresponds to the case cnt == 0 && k != 0 in
   17877 	    src/urandomb.c (fixed in r8762) with the 32-bit ABI.
   17878 	  * Output a warning (with a fatal error when the MPFR_COV_CHECK macro
   17879 	    is defined) if one doesn't get such a number, probably because the
   17880 	    GMP PRNG has changed.
   17881 
   17882 	[src/sqrt.c] The bug fixed in r9540 actually came from r9014, which
   17883 	incorrectly replaced MPFR_EXP by MPFR_SET_EXP. So, restored the
   17884 	previous code (re-adding the assertion check), keeping my comment
   17885 	from r9540 to explain why we don't use MPFR_SET_EXP.
   17886 
   17887 	[tests/tgeneric.c] Fixed overflow/underflow tests introduced in r9539:
   17888 	the tests were done in all rounding modes, but the code was incorrect
   17889 	if the exponent of the result depended on the rounding mode. So, the
   17890 	tests are now done only in the rounding mode previously selected. This
   17891 	should be sufficient to detect bugs.
   17892 
   17893 	[src/lngamma.c] For mpfr_lgamma and mpfr_lngamma, the exponent range
   17894 	was not restored in some cases (some large results). Bug introduced
   17895 	in r8917 (trunk only).
   17896 
   17897 	[src/{cos.c,sin.c}] Fixed bug related to the exponent range, introduced
   17898 	in r6461 with the use of mpfr_sincos_fast.
   17899 	Details:
   17900 	  For mpfr_sin, the exponent range was not restored, and restoring it
   17901 	  before calling mpfr_sincos_fast as this was done for mpfr_cos did
   17902 	  not work; indeed the source of this function shows that it needs an
   17903 	  extended exponent range. So, changed both mpfr_cos and mpfr_sin to
   17904 	  call mpfr_sincos_fast in the extended exponent range and restore the
   17905 	  exponent range at the end, like in usual code.
   17906 
   17907 	[tests/tgeneric.c] Check whether the exponent range has been
   17908 	modified by the tested function (which should never happen).
   17909 	This check triggers failures in tlgamma, tlngamma and tsin.
   17910 
   17911 	[src/sqrt.c] Fixed assertion failure in reduced exponent range.
   17912 	Note: This could happen only in very specific exponent ranges,
   17913 	in particular, which do not include the number 1.
   17914 
   17915 	[tests/tgeneric.c] Added overflow/underflow tests ( 4 failed tests).
   17916 
   17917 2015-06-08  Vincent Lefvre  <vincent (a] vinc17.net>
   17918 
   17919 	[src/zeta_ui.c]
   17920 	  * Support reduced exponent range for the generic case.
   17921 	  * Added logging.
   17922 	[tests/tzeta_ui.c] Added tests in reduced exponent range.
   17923 
   17924 	[src/add_ui.c] Fixed format string in MPFR_LOG_FUNC.
   17925 
   17926 2015-06-07  Vincent Lefvre  <vincent (a] vinc17.net>
   17927 
   17928 	[tests/tzeta_ui.c] Code simplification.
   17929 
   17930 	[tests/tzeta_ui.c] Test zeta(0) in reduced exponent range and all
   17931 	rounding modes.
   17932 
   17933 	[src/zeta_ui.c] Fixed zeta(0) in reduced exponent range.
   17934 	[tests/tzeta_ui.c] Added testcase.
   17935 
   17936 2015-06-05  Vincent Lefvre  <vincent (a] vinc17.net>
   17937 
   17938 	[src/{ui_div.c,ui_sub.c}] Correction for reduced exponent range.
   17939 
   17940 	[tests/tui_sub.c] Check overflow.
   17941 
   17942 	[tests/tui_div.c] Check overflow.
   17943 
   17944 	[tests/tgeneric.c] Removed useless parentheses.
   17945 
   17946 	[tests/tgeneric.c] Special cases with unsigned long argument.
   17947 
   17948 	[tests/tpow_all.c] Better flags output in error message.
   17949 
   17950 2015-06-04  Vincent Lefvre  <vincent (a] vinc17.net>
   17951 
   17952 	[src/set_q.c] Added missing MPFR_SAVE_EXPO_FREE in case of preliminary
   17953 	overflow or underflow (extreme cases).
   17954 
   17955 	[src/set_q.c] Replaced a "return" by MPFR_RET: this is at least needed
   17956 	in the extreme case cd != 0, and safer in general.
   17957 
   17958 	[tests/tset_q.c] Check the flags.
   17959 
   17960 	[src/mul_ui.c] Fixed bug in mpfr_mul_ui/si: the inexact flag wasn't set.
   17961 
   17962 	[tests/t{add,div,mul,sub}_ui.c] Replaced tgeneric_ui.c by tgeneric.c,
   17963 	showing a bug in mpfr_mul_ui (missing inexact flag).
   17964 
   17965 	[tests/{tui_div.c,tui_sub.c}] Added generic tests, yielding assertion
   17966 	failures (due to a reduced exponent range) when assertions are checked.
   17967 
   17968 	[tests/tgeneric.c] Major clean-up, with some minor corrections.
   17969 	Added support for unsigned long argument, which can be the first
   17970 	or the second one (another intent is to replace tgeneric_ui.c,
   17971 	which does fewer tests concerning the flags).
   17972 
   17973 	[tests/tdiv_d.c] Corrected the tested function for the generic tests.
   17974 
   17975 	[tests/td_div.c] Corrected the tested function for the generic tests.
   17976 
   17977 	[tests/tui_sub.c] Minor improvements.
   17978 
   17979 	[tests/tgeneric_ui.c] Added missing \n. Minor improvements.
   17980 
   17981 	[tests/tui_div.c] Minor improvements.
   17982 
   17983 2015-06-03  Vincent Lefvre  <vincent (a] vinc17.net>
   17984 
   17985 	[tests/trint.c] Corrected the description (copy-paste error in r9473).
   17986 
   17987 	[src/rint.c] Handle reduced exponent range.
   17988 
   17989 	[tests/trint.c] Extend basic_tests from [56,72] to [1,72] since i < 4
   17990 	(|x| < 1) are special cases in the implementation.
   17991 
   17992 	[tests/trint.c] Also run BASIC_TEST in reduced exponent range
   17993 	(emin = emax = EXP(x)).
   17994 
   17995 	[tests/trint.c] Also run BASIC_TEST2 in reduced exponent range
   17996 	(emin = emax = EXP(x)).
   17997 
   17998 	[src/rint.c] Added a comment about the mpfr_rint_* functions.
   17999 
   18000 	[src/rint.c] Simplified and fixed the mpfr_rint_* functions: in some
   18001 	corner cases, an intermediate overflow would not be propagated. No
   18002 	testcases added for this particular problem since huge precision
   18003 	numbers would be involved.
   18004 
   18005 2015-06-02  Vincent Lefvre  <vincent (a] vinc17.net>
   18006 
   18007 	[doc/mpfr.texi] Added description of the flags for the mpfr_rint,
   18008 	mpfr_ceil, mpfr_floor, mpfr_round, mpfr_trunc functions.
   18009 
   18010 2015-06-01  Vincent Lefvre  <vincent (a] vinc17.net>
   18011 
   18012 	[tests/trint.c] In the basic tests, test the flags.
   18013 
   18014 2015-05-31  Vincent Lefvre  <vincent (a] vinc17.net>
   18015 
   18016 	[tests/trint.c] Corrections for r9476 and r9477.
   18017 
   18018 	[configure.ac] For the gcc compiler, better choice of the -W flags
   18019 	when the selected language is C++ (e.g. when CC=g++).
   18020 
   18021 2015-05-29  Vincent Lefvre  <vincent (a] vinc17.net>
   18022 
   18023 	[tests/trint.c] Added basic tests of the mpfr_{trunc,floor,ceil,round}
   18024 	functions.
   18025 
   18026 	[tests/trint.c] Added basic tests of the mpfr_rint_* functions.
   18027 
   18028 	[doc/mpfr.texi] Added blank lines to improve readability.
   18029 
   18030 	[tests/trint.c] Updated the description (test_generic_round is now
   18031 	tested, which wasn't done at all before).
   18032 
   18033 	[tests/trint.c] Added generic tests for the mpfr_rint_* functions.
   18034 	Since all numbers in ]0,1/2[ round to the same value, in order to
   18035 	avoid redundant tests, increased the TEST_RANDOM_EMIN value to -20
   18036 	and set TEST_RANDOM_ALWAYS_SCALE to 1.
   18037 	Note: only these new tests generate an error if the change of the
   18038 	exponent range is no longer done in these mpfr_rint_* functions.
   18039 
   18040 2015-05-29  Vincent Lefvre  <vincent (a] vinc17.net>
   18041 
   18042 	[tests] Added always_scale argument (boolean) to tests_default_random()
   18043 	so that when it is true, scaling is always performed on random numbers
   18044 	generated by mpfr_urandomb(), instead of preferring numbers of the order
   18045 	of magnitude of 1 for half outputs. This will be useful for mpfr_rint_*
   18046 	tests.
   18047 
   18048 	For tgeneric.c, the value of this argument is controlled by a new macro
   18049 	TEST_RANDOM_ALWAYS_SCALE (0 by default, which corresponds to the current
   18050 	behavior). For the other tests that call tests_default_random(), the
   18051 	argument is set to 0, so that the behavior remains the same.
   18052 
   18053 2015-05-29  Vincent Lefvre  <vincent (a] vinc17.net>
   18054 
   18055 	[doc/mpfr.texi] Added a remark concerning the mpfr_rint_* functions.
   18056 
   18057 2015-05-28  Vincent Lefvre  <vincent (a] vinc17.net>
   18058 
   18059 	[src] Fixed allocation issue for multithreaded applications:
   18060 	https://sympa.inria.fr/sympa/arc/mpfr/2015-05/msg00001.html
   18061 	  * mpfr-gmp.{c,h}: made mpfr_allocate_func, mpfr_reallocate_func and
   18062 	    mpfr_free_func thread-local; updated MPFR_GET_MEMFUNC to execute
   18063 	    mp_get_memory_functions only when these pointers have not been set
   18064 	    to the actual function pointers yet.
   18065 	  * mpfr-impl.h: #include "mpfr-thread.h" earlier (before mpfr-gmp.h,
   18066 	    where MPFR_THREAD_ATTR is now used).
   18067 
   18068 2015-05-25  Vincent Lefvre  <vincent (a] vinc17.net>
   18069 
   18070 	[src/mpfr-gmp.c] Replaced mpfr_allocate_func and mpfr_free_func
   18071 	by __gmp_allocate_func and __gmp_free_func in mpfr_tmp_allocate
   18072 	and mpfr_tmp_free respectively, fixing the crash in talloc.
   18073 	See: https://sympa.inria.fr/sympa/arc/mpfr/2015-05/msg00001.html
   18074 
   18075 	[tests/talloc.c] Avoid a failure with --with-gmp-build due to the fact
   18076 	that the MPFR_ALLOCA_MAX macro is not defined in this case.
   18077 
   18078 2015-05-23  Vincent Lefvre  <vincent (a] vinc17.net>
   18079 
   18080 	Added libtool-tcc-rpath.patch from
   18081 	  https://lists.gnu.org/archive/html/libtool-patches/2015-05/msg00000.html
   18082 	so that tcc can be used with libtool 2.4.3 to 2.4.6.
   18083 	In doc/README.dev, documented how to use this patch (before a release).
   18084 
   18085 	[tests] Added talloc.c and updated check_PROGRAMS in Makefile.am.
   18086 	This test detects an allocation bug added in r8813, which occurs
   18087 	if mpfr_tmp_allocate() is invoked before __gmp_allocate_func when
   18088 	the GMP build is not used (thus this bug is not visible in most
   18089 	code since mpfr_init2 is generally called first, directly or not,
   18090 	and it uses __gmp_allocate_func). Details:
   18091 	  https://sympa.inria.fr/sympa/arc/mpfr/2015-05/msg00001.html
   18092 
   18093 	[tests/{tstdint.c,tvalist.c}] Added missing #include "mpfr-test.h"
   18094 	(detected with gcc -Werror=implicit-function-declaration), needed
   18095 	since r9447.
   18096 
   18097 2015-05-22  Vincent Lefvre  <vincent (a] vinc17.net>

   18099 	[src/mpfr-gmp.c] Code formatting.
   18100 
   18101 	[tests/tstckintc.c] Fixed undefined behavior (invalid pointer).
   18102 
   18103 	Define MPFR_ALLOCA_MAX macro: Maximum size for the use of alloca by
   18104 	temporary allocations (default: 16384).
   18105 
   18106 	[tests/{tstdint.c,tvalist.c}] Use tests_start_mpfr / tests_end_mpfr,
   18107 	in particular to detect a wrong MPFR version (due to a libtool bug).
   18108 
   18109 2015-05-21  Vincent Lefvre  <vincent (a] vinc17.net>
   18110 
   18111 	[autogen.sh] Exit with the exit status of autoreconf. Thus a failure
   18112 	will be noticed more easily.
   18113 
   18114 	[NEWS] Update.
   18115 
   18116 	[acinclude.m4] Added a comment about memmove and memset being considered
   18117 	to be missing when gcc -Werror is used, because of a "conflicting types
   18118 	for built-in function" error.
   18119 
   18120 	[acinclude.m4] Various corrections in the tests:
   18121 	  * MPFR_CHECK_MP_LIMB_T_VS_LONG was always failing due to a typo.
   18122 	  * MPFR_FUNC_GMP_PRINTF_SPEC: missing #include <string.h> for strcmp.
   18123 	  * Replaced rint by nearbyint in messages (as nearbyint is tested).
   18124 	  * Avoid warnings to avoid failures when -Werror is used.
   18125

   18127 
   18128 	[tests/{tcmp_d.c,tcmp_ld.c,tget_d.c}] Avoid warnings concerning unused

   18138 	[doc/mpfr.texi] Correction and improvements in the formatting.
   18139 
   18140 	[doc/mpfr.texi] Added a warning for mpfr_set_prec and mpfr_prec_round

   18142 
   18143 	[doc/mpfr.texi] Typo in the latest change.
   18144 
   18145 	[doc/mpfr.texi] Rewrote the mpfr_swap description. This should solve

   18161 	[doc/mpfr.texi] Update concerning mpfr_sum.
   18162 
   18163 	[doc/sum.txt] The specification of the sign of a zero result only
   18164 	applies to an exact zero, of course (for an inexact zero result,
   18165 	the usual rule of the rounding mode is applied).
   18166 
   18167 	[tests/t[ne]random_chisq.c] Fixed memory leak (detected by GCC's

   18178 
   18179 	[tests/tests.c] Make tests_default_random() more intuitive, avoiding
   18180 	automatic changes of the current exponent range in some cases: instead
   18181 	of adding some random exponent in [emin,emax] to the exponent of the
   18182 	random number x in ]0,1[, force this random exponent to be the one of
   18183 	x, so that its exponent is guaranteed to be in [emin,emax]. This avoids
   18184 	a failure in tsum due to the fact that the exponent range was changed
   18185 	automatically (and not restored).
   18186 
   18187 	[tests/tsum.c] In cancel(), increase the number of tests from 8 to 1000.
   18188 	This is much more, but the test is fast compare to other ones so that
   18189 	the running time increases by a few percents only. And this triggers a
   18190 	new bug: the exponent range is not restored (on a 64-bit machine).
   18191 
   18192 	[tests/tsum.c] Changes in cancel():
   18193 	  * The fail-test was x[n] > bound instead of |x[n]| > bound, so that
   18194 	    some failures could be missed.
   18195 	  * More output in case of failure.
   18196 	  * Handle underflow in the bound computation. This fixes an incorrect
   18197 	    failure due to a bound rounded toward zero instead of toward +inf
   18198 	    with GMP_CHECK_RANDOMIZE=1431478020 (found by the nightly tests).
   18199 
   18200 	[tools/nightly-test] Run "make check" with VERBOSE=1 in order to have

   18218 
   18219 	[doc/README.dev] Grouped everything about the test suite near the end
   18220 	of this file. Added information about how the test suite works since
   18221 	the full Automake 1.13 support (r8821).
   18222 
   18223 	To take into account that Automake 1.13 or later will be used:
   18224 	  * doc/mpfr.texi, INSTALL: updates related to "make check".
   18225 	  * configure.ac: require Automake 1.13 since the documentation now
   18226 	    assumes that 1.13 or later is used (and because previous Automake
   18227 	    versions are no longer tested).

   18234 
   18235 	Merged the new-sum branch:
   18236 	  * New feature for developers in order to improve the testsuite:
   18237 	    value coverage checking (MPFR_COV_CHECK macro), allowing one
   18238 	    to check whether some combinations of values are tested. See
   18239 	    example of use in src/sum.c and tests/tsum.c files.
   18240 	  * src/sum.c: full rewrite of mpfr_sum. Note: the documentation
   18241 	    of the algorithm in doc/sum.txt is currently a bit obsolete.
   18242 	  * tests/tsum.c: many new tests, some of them specifically written
   18243 	    for the new algorithm and implementation.
   18244 
   18245 2015-04-09  Vincent Lefvre  <vincent (a] vinc17.net>
   18246 
   18247 	[src/sum.c] Fixed bug: mpn functions do not accept a zero size argument.
   18248 
   18249 	[tests/tsum.c] Replaced a mpfr_inits by a mpfr_inits2.
   18250 
   18251 	[tests/tsum.c] Added a simple test that triggers a glibc free() error
   18252 	or segmentation fault when MPFR is configured with GMP 6.0.0 built
   18253 	with "--disable-alloca ABI=32". GCC's address sanitizer shows a
   18254 	heap-buffer-overflow. This is mainly for debugging as this problem
   18255 	also occurs in other tests (it is quite generic).
   18256 
   18257 	[tests/tsum.c] Removed a temporary comment.
   18258 
   18259 	Merged the latest changes from the trunk.
   18260 
   18261 	[tests/tsum.c] Added check_underflow test.

   18264 
   18265 	[tests/tsum.c] Comments.
   18266 
   18267 	[src/sum.c] Bug fix: use MPFR_EXP instead of MPFR_SET_EXP to set the
   18268 	exponent since it can be outside the current exponent range before
   18269 	it is checked with mpfr_check_range. Also added a static assertion
   18270 	(always satisfied in practice) to make sure that exponent related
   18271 	computations cannot yield an integer overflow.
   18272 
   18273 	[tests/tsum.c] Added check_overflow test, which triggers a bug.
   18274 
   18275 2015-03-31  Vincent Lefvre  <vincent (a] vinc17.net>
   18276 
   18277 	[tests/tsum.c] Completed the cancel test (generic random tests with
   18278 	cancellations): check the bound on the result.
   18279 
   18280 	[tests/tsum.c] Improved the check4 test:
   18281 	  * removed some not very useful tests to reduce the running time;
   18282 	  * added tests checking "MPFR_RNDN, tmd=2, rbit=0, sst=1, negative",
   18283 	    which was the only remaining one output by check_coverage (when
   18284 	    MPFR_COV_CHECK is defined).
   18285 
   18286 	[tests/tsum.c] Reduced the check4 test because it was much too long
   18287 	compared to the other tests. The bug fixed in r9356 is still triggered
   18288 	and "MPFR_RNDN, tmd=2, rbit=0, sst=0, negative" is still checked.
   18289

   18291 
   18292 	[tests/tsum.c] Updated comment of the check4 test.
   18293 
   18294 	[src/sum.c] Bug triggered by the check4 test fixed.
   18295 
   18296 	[tests/tsum.c] Another correction in the check4 test.
   18297 
   18298 	[tests/tsum.c] In the check4 test, two terms didn't correspond to
   18299 	the formula given in the comment; corrected these terms (the same
   18300 	bug is triggered).
   18301 
   18302 	[tests/tsum.c] Forgot the h in the error message of the check4 test.
   18303 
   18304 	[tests/tsum.c] Extend the check4 test even further.
   18305 
   18306 	[tests/tsum.c] Extend the check4 test even further.
   18307 
   18308 	[tests/tsum.c] Added check4 test, which triggers a bug.
   18309 
   18310 2015-03-27  Vincent Lefvre  <vincent (a] vinc17.net>
   18311 
   18312 	[src/sum.c] In the TMD detection:
   18313 	  * improved variable nbits to decrease the number of operations;
   18314 	  * added some comments;
   18315 	  * fixed the shift count bug triggered by the bug20150327 test.
   18316 
   18317 	[tests/tsum.c] Added bug20150327 testcase.
   18318 
   18319 	[tests/tsum.c] Corrected test of the ternary values inex1 and inex2.

   18331 	[tests/tsum.c] More tests.
   18332 
   18333 	[src/sum.c] Added comments.
   18334 
   18335 	[src/sum.c] In the final rounding, forgot to handle the possible

   18342 
   18343 	[tests/tsum.c] New tests.
   18344 
   18345 	[tests/tsum.c] Value coverage checking: tmd can be 2 only for MPFR_RNDN.

   18348 
   18349 	[src/sum.c] Better logging.
   18350 
   18351 	[src/sum.c] Bug fix: the sum_raw code was unnecessarily assuming
   18352 	too much; thus, removed too parameters, which can be very easily
   18353 	recomputed only when they make sense.
   18354 
   18355 2015-03-12  Vincent Lefvre  <vincent (a] vinc17.net>
   18356

   18370 
   18371 	[doc/sum.txt] Updated TODO.
   18372 
   18373 	[doc/sum.txt] Added TODO (since the description is a bit obsolete).
   18374 
   18375 	[src/sum.c] In the latest commit, the temporary area was split for
   18376 	the computations that determine the sign of the error term in case
   18377 	the TMD occurs, as these computations occur earlier in the code.
   18378 	This was actually not necessary since the content of the accumulator
   18379 	has already been copied to the final destination (only sign handling
   18380 	and rounding have not been done yet, but they entirely take place in
   18381 	the destination). As a consequence, let's revert the code related to
   18382 	this split. The actual changes concerning the merge of pre-rounding
   18383 	and final rounding can be seen with "svn diff -r 9328:9330".
   18384 
   18385 	[src/sum.c]
   18386 	  * Removed any reference to the obsolete step numbering.
   18387 	  * Merged pre-rounding and final rounding, simplifying the code.
   18388 	    The correction value still needs to be fixed.
   18389 
   18390 	[src/sub1sp.c] Avoid an unnecessary mpn_lshift after an mpn_sub_1 when
   18391 	the initial value was a power of two.
   18392 
   18393 	[src/next.c] Avoid an unnecessary loop when the exponent decreases.

   18404 
   18405 2015-02-25  Vincent Lefvre  <vincent (a] vinc17.net>
   18406 
   18407 	[src/sum.c] Improved the setting of sst (Step 8), using the fact
   18408 	that the accumulator is 0 iff cancel = 0.
   18409 
   18410 	[src/sum.c] Bug fix: when determining the sticky bit, the search was
   18411 	starting at the rounding bit instead of the bit following it.
   18412 
   18413 	[tests/tsum.c] New tests.
   18414 
   18415 	[src/sum.c] More logging.

   18417 	[tests/tsum.c] In the generic test, also test with negative numbers.
   18418 
   18419 	Updated value coverage checking for mpfr_sum.
   18420 
   18421 	[doc/README.dev] Document the new MPFR_COV_CHECK macro.
   18422 
   18423 	Value coverage checking when MPFR_COV_CHECK is defined, initially
   18424 	for mpfr_sum.
   18425 
   18426 	[src/sum.c] Bug fix in the ternary value.
   18427 
   18428 	[tests/tsum.c] Added check of the ternary value.

   18470 	(some parentheses were missing).
   18471 
   18472 	[src/sum.c] Update: sum_raw, with a new prototype, now reiterates until
   18473 	the error bound is acceptable; thus the "while" loops have been removed
   18474 	from sum_aux.
   18475 
   18476 2015-02-20  Vincent Lefvre  <vincent (a] vinc17.net>
   18477 
   18478 	[tests/tsum.c] Increased the number of tests to get 2 current failures
   18479 	with a "break" in the last loop of sum.c (m = 438, m = 3780), without
   18480 	the exit() in the generic test. Improved error message.
   18481 
   18482 	[tests/tsum.c] Completely rewrote the generic test (now allows one to
   18483 	detect that the implementation is incomplete when adding a "break" in
   18484 	the last loop of sum.c).
   18485

   18510 
   18511 	[tests/tsum.c] Removed the obsolete mpfr_sum_sort related test

   18543 	Added algorithms.fls (generated by latexmk) to svn:ignore property.
   18544 
   18545 2015-01-21  Vincent Lefvre  <vincent (a] vinc17.net>
   18546 
   18547 	[tests/tfpif.c] Updated a mpfr_set_zero line for consistency and
   18548 	better readability.
   18549 
   18550 	[tools/mpfrlint] Added mpfr_set_(inf|zero) tests on the sign.
   18551 
   18552 	[tests/tset.c] More mpfr_set_inf tests.
   18553 
   18554 	[tests/tset.c] More mpfr_set_zero tests.
   18555 
   18556 	[tools/mbench/timp.h] Spelling mistake in a comment.
   18557 
   18558 2014-12-17  Vincent Lefvre  <vincent (a] vinc17.net>
   18559 
   18560 	[src/sum.c] Added a TODO.
   18561 
   18562 	[src/sum.c] Added missing closing parenthesis from r9257. Step 8 update.
   18563 
   18564 	[doc/sum.txt] Step 8: renamed "sgn" to "sst".
   18565 
   18566 	[doc/sum.txt] Merged old Step 9 with Step 8; minor changes.
   18567 
   18568 	[src/sum.c] Avoid a loop in some cases.
   18569 
   18570 	[src/sum.c] Remember the rounding bit for Step 9; correction for
   18571 	halfway cases in round to nearest.
   18572 
   18573 	[doc/mpfr.texi] Updated the month.
   18574 
   18575 2014-12-16  Vincent Lefvre  <vincent (a] vinc17.net>
   18576 
   18577 	[NEWS] Added an item about improved caching.
   18578 	[NEWS,doc/mpfr.texi] In particular, mention the minimum of 10% increase
   18579 	of the precision (done in r8967).
   18580 
   18581 	[NEWS] Note that the behavior of the mpfr_set_exp function changed.
   18582 	[src/Makefile.am] As this changed the ABI (the old, unwise behavior
   18583 	was documented), reset -version-info age. This is not that bad since
   18584 	there are other changes in the behavior, though regarded as bugs or
   18585 	previously undocumented behavior.
   18586 
   18587 	Moved src/sum.txt into the doc directory, and updated the reference
   18588 	in src/sum.c.
   18589 
   18590 2014-12-12  Vincent Lefvre  <vincent (a] vinc17.net>
   18591 
   18592 	[src/sum.txt] Update (Step 9).
   18593 
   18594 	[src/sum.txt] Correction.
   18595 
   18596 2014-12-11  Vincent Lefvre  <vincent (a] vinc17.net>
   18597 
   18598 	[src/sum.*] Update.
   18599 
   18600 2014-12-04  Vincent Lefvre  <vincent (a] vinc17.net>
   18601 
   18602 	[doc/README.dev] Mention the tools/build-patch script.
   18603 
   18604 2014-12-03  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   18605 
   18606 	pointed to Feature Request
   18607 
   18608 2014-11-28  Vincent Lefvre  <vincent (a] vinc17.net>
   18609 
   18610 	[src/sum.c] Determine the number of cancelled bits in sum_raw instead
   18611 	of the main loop, since it will also be useful in Step 8.
   18612 
   18613 	[src/sum.*] Update (Step 8).
   18614 
   18615 2014-11-24  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   18616 
   18617 	fixed issue reported by Dan Grayson:
   18618 	https://gforge.inria.fr/tracker/?func=detail&atid=619&aid=18314&group_id=136
   18619 
   18620 2014-11-13  Vincent Lefvre  <vincent (a] vinc17.net>
   18621 
   18622 	[tools/mpfrlint] Minor change concerning mp_limb_t.
   18623 
   18624 2014-11-12  Vincent Lefvre  <vincent (a] vinc17.net>
   18625 
   18626 	Style improvements.
   18627 
   18628 	[src/exp_2.c] Improved t = 0 test.
   18629 
   18630 	[src/exp_2.c] Fixed a bug added in r9233 (a case t = 0 was no longer
   18631 	taken into account).
   18632 
   18633 	[src/exp_2.c] GNU coding style.
   18634 
   18635 2014-11-11  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   18636 
   18637 	improve mpfr_exp2 (patch from Patrick Pelissier)
   18638 
   18639 2014-11-09  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   18640 
   18641 	improve mpfr_atan for small precision (patch from Patrick Pelissier)
   18642 
   18643 	added check for libquadmath (not used)
   18644 
   18645 2014-11-03  Vincent Lefvre  <vincent (a] vinc17.net>
   18646 
   18647 	[src/cache.c] Improved mpfr_clear_cache in case mpfr_free_cache is
   18648 	called often (like with GC-based systems). Patch by Patrick Plissier.
   18649 
   18650 	[src] Applied patch by Patrick Plissier to allocate some constant-size
   18651 	MPFR numbers on the stack instead of using mpfr_init2, and replace some
   18652 	MPFR_ASSERTN by MPFR_ASSERTD.
   18653 
   18654 2014-10-31  Vincent Lefvre  <vincent (a] vinc17.net>
   18655 
   18656 	[src/get_str.c] Improved comments.
   18657 
   18658 2014-10-30  Vincent Lefvre  <vincent (a] vinc17.net>
   18659 
   18660 	[src/get_str.c] Free the temporary memory allocated in the Ziv loop ASAP
   18661 	and at a single place (the code should be clearer like that).
   18662 
   18663 	[src/get_str.c] Code refactoring.
   18664 
   18665 	[tests/tget_str.c] Code formatting.
   18666 
   18667 	[tests/tget_str.c] Fixed a test that made mpfr_get_str crash with
   18668 	logging (even when the base is invalid, the MPFR number must be
   18669 	initialized).
   18670 
   18671 	[src/check.c] Added a note saying that mpfr_check() must not be called
   18672 	  on statically allocated numbers (only used inside MPFR).
   18673 	[src/get_str.c] Removed the "MPFR_ASSERTD (mpfr_check (p));" (added in
   18674 	  previous commit) because of that.
   18675 
   18676 	[src/get_str.c] Added some logging (MPFR_LOG_*), which triggers a crash
   18677 	in tget_str with MPFR_LOG_ALL=1. An analysis with gdb shows that this
   18678 	is due to an invalid MPFR number in mpfr_ceil_mul(). Added a
   18679 	  MPFR_ASSERTD (mpfr_check (p));
   18680 	there, which fails in tget_str (this was the cause of the crash), even
   18681 	without logging.
   18682 
   18683 2014-10-29  Vincent Lefvre  <vincent (a] vinc17.net>
   18684 
   18685 	mpfr_get_str now sets the NaN flag on NaN input. See:
   18686 	  https://sympa.inria.fr/sympa/arc/mpfr/2014-10/msg00013.html and
   18687 	  https://gforge.inria.fr/tracker/index.php?func=detail&aid=18228&group_id=136&atid=619
   18688 	Also completed the mpfr_get_str description in mpfr.texi concerning
   18689 	the special numbers and the exception flags.
   18690 
   18691 2014-10-28  Vincent Lefvre  <vincent (a] vinc17.net>
   18692 
   18693 	[doc/mpfr.texi] Updated the month.
   18694 
   18695 	[doc/mpfr.texi] Removed a spurious "an".
   18696 
   18697 	[src/get_str.c] Improved style consistency.
   18698 
   18699 	[doc/mpfr.texi] In the mpfr_get_str description, note that the type
   18700 	mpfr_exp_t is large enough to hold the exponent in all cases.
   18701 
   18702 	[doc/mpfr.texi] Improved mpfr_get_str description concerning the
   18703 	returned pointer (it was ambiguous in the case of an invalid base).
   18704 
   18705 2014-10-09  Vincent Lefvre  <vincent (a] vinc17.net>
   18706 
   18707 	[tests/tests.c] Updated the error message last changed.
   18708 
   18709 	[tests/tests.c] Updated the error message last changed + comment.
   18710 
   18711 2014-10-08  Vincent Lefvre  <vincent (a] vinc17.net>
   18712 
   18713 	[tests/Makefile.am] Added a reference to the bug I've just reported
   18714 	against GNU Automake (completing the other references).
   18715 
   18716 	[tests/tests.c] Updated the error message last changed.
   18717 
   18718 2014-10-07  Vincent Lefvre  <vincent (a] vinc17.net>
   18719 
   18720 	[tests/tests.c] Changed an error message.
   18721 
   18722 2014-10-06  Vincent Lefvre  <vincent (a] vinc17.net>
   18723 
   18724 	[src/sum.txt] Update.
   18725 
   18726 	[src/sum.c] Improved a comment.
   18727 
   18728 	[src/sum.c] Got rid of maxexp2 in the mpfr_sum function, since after the
   18729 	  sum in the main iteration, the old maxexp value is no longer needed:
   18730 	  it's simpler to reuse maxexp for maxexp2 since maxexp2 will be the new
   18731 	  maxexp value at the next iteration.
   18732 	[src/sum.txt] Update, in particular concerning the variables used in the
   18733 	  implementation.
   18734 
   18735 2014-09-09  Vincent Lefvre  <vincent (a] vinc17.net>
   18736 
   18737 	[tests] Corrections for builds with "config.h".
   18738 
   18739 2014-08-26  Vincent Lefvre  <vincent (a] vinc17.net>
   18740 
   18741 	[src/sum.c] Reset copyright years to 2014 since the whole file is
   18742 	being rewritten from scratch (i.e. everything is new material).
   18743 
   18744 	[src/sum.txt] Update.
   18745 
   18746 2014-08-25  Vincent Lefvre  <vincent (a] vinc17.net>
   18747 
   18748 	[src/sum.*] Update (Step 7, including a part of Step 8 in Step 7).
   18749 
   18750 	[src/sum.c] Correction (Step 7).
   18751 
   18752 	[src/sum.c] Corrected r9197 (two "else" branches were mixed up), and
   18753 	update (Step 8).
   18754 
   18755 	[src/sum.c] Correction when determining the early value of inex.
   18756 
   18757 	[src/sum.c] Update (Step 8).
   18758 
   18759 	[src/sum.txt] Update about the value of d.
   18760 
   18761 	[src/sum.c] Added comments for Step 7 about carry and inex.
   18762 
   18763 2014-08-22  Vincent Lefvre  <vincent (a] vinc17.net>
   18764 
   18765 	Merged the latest changes from the trunk (here, tools/mpfrlint).
   18766 
   18767 	[tools/mpfrlint] Avoid false positives in the check of MPFR_LOG_MSG.
   18768 
   18769 	[src/sum.*] Update (Step 7).
   18770 
   18771 2014-08-21  Vincent Lefvre  <vincent (a] vinc17.net>
   18772 
   18773 	[src/sum.txt] Updated Note 2 again.
   18774 
   18775 	[src/sum.txt] Updated Note 2.
   18776 
   18777 	[src/sum.*] Various corrections, and update.
   18778 
   18779 	Merged the latest changes from the trunk.
   18780 
   18781 	[src] Cleaner use of MPFR_SET_SIGN.
   18782 
   18783 2014-08-19  Vincent Lefvre  <vincent (a] vinc17.net>
   18784 
   18785 	[src/sum.c] Updated comments.
   18786 
   18787 	[src/sum.c] Update (Step 7).
   18788 
   18789 	[src/sum.c] Improved description of sum_raw.
   18790 
   18791 	[src/sum.c] Added description of sum_raw.
   18792 
   18793 2014-08-18  Vincent Lefvre  <vincent (a] vinc17.net>
   18794 
   18795 	[src/sum.c] Suppressed a level of block (which became rather useless
   18796 	now that Step 3 has been moved to a separate function).
   18797 
   18798 	[src/sum.c] Moved Step 3 to a separate auxiliary function sum_raw.
   18799 
   18800 	[src/sum.c] Renamed variables: p -> x, pe -> xe, pq -> xq (because
   18801 	the p suffix is used here for pointers to mp_limb_t).
   18802 
   18803 	[src/sum.c] Updated comments.
   18804 
   18805 2014-08-17  Vincent Lefvre  <vincent (a] vinc17.net>
   18806 
   18807 	[TODO] Added item on tests (mpfr.h macros vs mpfr-impl.h).
   18808 
   18809 	[src/mpfr.h] Fixed the mpfr_signbit() macro, which depended on
   18810 	mpfr-impl.h (the problem wasn't detected in the tests since mpfr-impl.h
   18811 	is included in them). Thanks to Rob for the bug report.
   18812 
   18813 2014-08-14  Vincent Lefvre  <vincent (a] vinc17.net>
   18814 
   18815 	[src/sum.*] Update (Step 7).
   18816 
   18817 2014-08-13  Vincent Lefvre  <vincent (a] vinc17.net>
   18818 
   18819 	[src/sum.txt] Update.
   18820 
   18821 	[src/sum.txt] Update (another tricky case).
   18822 
   18823 2014-08-12  Vincent Lefvre  <vincent (a] vinc17.net>
   18824

   18830 
   18831 	[src/sum.*] Completed Step 6.
   18832 
   18833 2014-08-08  Vincent Lefvre  <vincent (a] vinc17.net>
   18834 
   18835 	[src/sum.txt] Update.
   18836 
   18837 	[src] Moved the comment about the mpfr_sum algorithm from sum.c to
   18838 	a new file sum.txt (this will later go into algorithms.tex).
   18839 
   18840 2014-08-06  Vincent Lefvre  <vincent (a] vinc17.net>
   18841 
   18842 	[src/sum.c] Updated the algorithm.
   18843 
   18844 	[src/sum.c] Updated the algorithm.
   18845 
   18846 2014-08-05  Vincent Lefvre  <vincent (a] vinc17.net>
   18847 
   18848 	[src/sum.c] Added some log messages.
   18849 
   18850 	Merged the latest changes from the trunk (but reverted tests/tsum.c).
   18851 
   18852 	[tools/mpfrlint] Improved check of MPFR_LOG_MSG.
   18853 
   18854 	[tools/mpfrlint] Replaced {src,tests}/*.{c,h} by $srctests.
   18855 
   18856 	[src/ai.c] Corrected log messages.
   18857 
   18858 	[doc/mpfr.texi] Updated the month.
   18859 
   18860 	Update concerning the P type specifier for formatted output, since
   18861 	mpfr_prec_t was changed to a signed type in MPFR 3.0.0.
   18862 	  * doc/mpfr.texi: d and i can be used (o, u, x, and X are still OK
   18863 	    in practice since a mpfr_prec_t value is usually nonnegative);
   18864 	    changed a "unsigned int" to "int".
   18865 	  * src/vasprintf.c: updated a comment.
   18866 
   18867 2014-07-23  Vincent Lefvre  <vincent (a] vinc17.net>
   18868 
   18869 	[tests/mpf_compat.h] Fixed a bug (mpf_set_prec_raw usage with GMP/MPF).
   18870 
   18871 	[tests]
   18872 	  * mpfr-test.h: no longer include <stdio.h> right here since the
   18873 	    included mpfr-impl.h does that and even better for C++.
   18874 	  * mpf_compat.c, mpfr_compat.c: include mpfr-test.h as it does useful
   18875 	    things (in particular, include config.h via mpfr-impl.h if there
   18876 	    is one, and define __MPFR_TEST_H__ for mpfr-impl.h).
   18877 	  * mpf_compat.h: no longer include some headers already included
   18878 	    via mpfr-test.h (see above change); added tests_start_mpfr and
   18879 	    tests_end_mpfr (showing memory inconsistency with mpf_compat).
   18880 
   18881 2014-07-20  Vincent Lefvre  <vincent (a] vinc17.net>

   18896 	  * Check that __gmp[nz]_ functions are not used (with 2 exceptions),

   18905 	that testing a guard before a #include may yield incorrect behavior.

   18914 2014-07-08  Vincent Lefvre  <vincent (a] vinc17.net>
   18915 
   18916 	Renamed the MPFR_TEST_DIVBYZERO macro to MPFR_TESTS_DIVBYZERO
   18917 	for consistency with MPFR_TESTS_TIMEOUT.
   18918 
   18919 2014-07-07  Vincent Lefvre  <vincent (a] vinc17.net>
   18920 
   18921 	[tests] Minor improvements.
   18922 
   18923 	[tests/reuse.c,tests/taway.c] Added mpfr_ai and mpfr_digamma.
   18924 
   18925 	[tests/tmul_d.c] Minor improvement.
   18926 
   18927 	[src/mul.c] Fixed a test when MPFR_WANT_ASSERT >= 2 (NaN with non-NaN
   18928 	was not detected as an error).
   18929 
   18930 	[src] MPFR_WANT_ASSERT clean-up.
   18931 	Note: the mul.c test for MPFR_WANT_ASSERT >= 3 is now enabled for
   18932 	MPFR_WANT_ASSERT = 2 (since setting MPFR_WANT_ASSERT to 3 was not
   18933 	possible with configure options), and fixed.
   18934 
   18935 	Added debug of branch prediction / --enable-debug-prediction configure
   18936 	option (patch from Patrick Plissier, with some changes).
   18937 
   18938 2014-07-02  Vincent Lefvre  <vincent (a] vinc17.net>
   18939 
   18940 	[src/round_raw_generic.c] Updated comment about MPFR_RNDNA.
   18941 
   18942 	[doc/mini-gmp] Added a note about MPFR_USE_MINI_GMP.
   18943 
   18944 	[doc/README.dev] Added an item on the use of GMP functions.
   18945 
   18946 	[doc/README.dev] "To make a release": test with mini-gmp.
   18947 
   18948 	Removed the need of MPFR_USE_MINI_GMP tests for mpfr_[ne]random
   18949 	functions (source and tests) as mpfr_random_deviate_value no longer
   18950 	needs mpq_t (since r9066). Also removed a static assertion in
   18951 	src/random_deviate.c for the same reason.
   18952 	Note: the change done in r9133 is now really useful!
   18953 
   18954 	[src/mpfr.h] Added other missing "#ifndef MPFR_USE_MINI_GMP".
   18955 
   18956 	[tests/t[ne]random.c] Code clean-up: added !defined(MPFR_USE_MINI_GMP)
   18957 	to protect mpfr_printf. This is actually not needed due to the initial
   18958 	"#ifndef MPFR_USE_MINI_GMP" but this is for a different reason.
   18959 
   18960 	[tests/t[ne]random.c] Reverted the changes done in r9126,9127,9130
   18961 	and added a proper comment.
   18962 
   18963 	[src/mpfr.h] Added a missing "#ifndef MPFR_USE_MINI_GMP"
   18964 	(not really useful, but cleaner).
   18965 
   18966 	[tests/t[ne]random.c] Fixed the change done in r9126 and r9127.
   18967 
   18968 	Renamed WANT_MINI_GMP to MPFR_USE_MINI_GMP as it is used in mpfr.h
   18969 	(all MPFR macros that appear there should start with MPFR_ to avoid
   18970 	conflicts with other software).
   18971 
   18972 	[tools/mpfrlint] Detect the possible use of forbidden macros in mpfr.h.
   18973 
   18974 	[tests/terandom.c] Put the WANT_MINI_GMP test at the right place, like
   18975 	what has been done for "tests/tnrandom.c".
   18976 
   18977 	[tests/tnrandom.c] Put the WANT_MINI_GMP test at the right place
   18978 	(at the same time of the HAVE_STDARG test), but this should be
   18979 	improved in the future, e.g. with a HAVE_MPFR_PRINTF macro.

   18994 
   18995 	patch from Charles Karney:
   18996 	> Here is the patch which repeats the chi-squared tests in the case of
   18997 	> suspiciously high values.  The probability of a false positive is now
   18998 	> 1/10^9.  I also got rid of the mpfr_printf's.
   18999 
   19000 2014-06-30  Vincent Lefvre  <vincent (a] vinc17.net>
   19001 
   19002 	[tools/build-patch]
   19003 	  * Removed unnecessary quotes for better readability (this is zsh).
   19004 	  * When <patchlevel> (second argument) is used, use the correct name
   19005 	    for the generated patch; at the same time, fixed a checkobj call.
   19006 	  * Added comment about typical usage.
   19007 
   19008 	[tools/build-patch] Correction if MPFR_CURRENT_DIR is set: to make sure
   19009 	that it is always up-to-date, we want to allow it to be a symlink (e.g.
   19010 	.../mpfr-current), so that we want to call realpath on it.
   19011 
   19012 	Added tools/build-patch zsh script to transform a raw patch into a patch
   19013 	to be put on the MPFR www server.
   19014 
   19015 	[src/mpfr.h] For the mpfr_{mul,div}_si macros: s/positive/non-negative/
   19016 
   19017 	[configure.ac] Correction of two "configure --help" messages
   19018 	(from Patrick Plissier and other changes).
   19019 
   19020 	[src/mpfr.h] Coding style.
   19021 
   19022 	New macros for mpfr_{mul,div}_ui to optimize the call when the integer
   19023 	is a constant number that is a power of 2.
   19024 	New macros for mpfr_{mul,div}_si to optimize the call when the integer
   19025 	is a constant number that is positive.
   19026 	(Modified patch from Patrick Plissier)

   19028 2014-06-26  Vincent Lefvre  <vincent (a] vinc17.net>
   19029 
   19030 	[src/vasprintf.c] Improved comments.
   19031 
   19032 	[src/vasprintf.c] Fixed assertion failures for tiny numbers (the code
   19033 	was correct, but the assertions didn't check against the right bound).
   19034 
   19035 	[src/div.c] Bug fix: avoid integer overflow in the code added in r9086
   19036 	(now tdiv no longer fails).
   19037 
   19038 	[src/div.c] Bug fix: avoid an integer overflow when dividing the
   19039 	largest finite MPFR number by the smallest positive one.
   19040 	(merged changeset r9105 from the 3.1 branch)
   19041 
   19042 	[tests/tdiv.c] Forgot "exit (1);".
   19043 
   19044 	[tests/tdiv.c] Added mpfr_div tests on extreme values. This detects
   19045 	2 problems (at least on a 64-bit machine): a result is not a valid
   19046 	MPFR number (mpfr_check fails) and the flags are incorrect.
   19047 
   19048 2014-06-25  Vincent Lefvre  <vincent (a] vinc17.net>
   19049 
   19050 	[tests/tsprintf.c] Fixed test added in r9099 (the problem was unrelated
   19051 	to the bug in vasprintf.c).
   19052 
   19053 	[tests/tsprintf.c] Added a test with the minimum exponent
   19054 	(currently triggers an assertion failure in vasprintf.c).
   19055 
   19056 2014-06-25  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   19057 
   19058 	define MPFR_SKIP_EXTREME to avoid currently failing tsum test
   19059 
   19060 2014-06-25  Vincent Lefvre  <vincent (a] vinc17.net>
   19061 
   19062 	[tests/tsum.c] Do not run the check_extreme test (which currently fails)
   19063 	when the MPFR_SKIP_EXTREME environment variable is defined.
   19064 
   19065 2014-06-25  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   19066 
   19067 	reconfigure for mpfrbench
   19068 
   19069 	speedup in mpfr_div for n/n division, using mpz_tdiv_q
   19070 
   19071 2014-06-25  Vincent Lefvre  <vincent (a] vinc17.net>
   19072 
   19073 	[tools/mpfrlint] Check when simple mp_limb_t constants could be used
   19074 	(MPFR_LIMB_ZERO, MPFR_LIMB_ONE, and MPFR_LIMB_MAX).
   19075 
   19076 	Merged the latest changes from the trunk.
   19077 
   19078 	Use MPFR_IS_NEG and MPFR_IS_POS instead of comparing the sign with 0.
   19079 	Done with
   19080 	  perl -pi -e '
   19081 	    s/MPFR_SIGN *\(([^)]+)\) *<=? *0/MPFR_IS_NEG ($1)/g;

   19083 	    ' {src,tests}/*.{c,h}
   19084 	and some manual changes.
   19085 
   19086 	More code clean-up (for both consistency and readability):
   19087 	  * Use the simple mp_limb_t constants when possible.
   19088 	  * New internal macro MPFR_IS_NORMALIZED.
   19089 	Note: this was done with
   19090 	  perl -pi -e '
   19091 	    s/~ *\(mp_limb_t\) *0/MPFR_LIMB_MAX/g;
   19092 	    s/\(mp_limb_t\) *-1/MPFR_LIMB_MAX/g;
   19093 	    s/\(mp_limb_t\) *0/MPFR_LIMB_ZERO/g;
   19094 	    s/\(mp_limb_t\) *1L?/MPFR_LIMB_ONE/g' {src,tests}/*.{c,h}
   19095 	  svn revert src/mpfr-impl.h
   19096 	and some manual changes.
   19097 
   19098 	Code clean-up:
   19099 	  * Simplified the definition of simple mp_limb_t constants: it is
   19100 	    better to avoid GMP internals when there is a standard way.
   19101 	  * Replaced the use of MP_LIMB_T_MAX by the new macro MPFR_LIMB_MAX.
   19102 	  * So, removed the now useless MP_LIMB_T_MAX and GMP_LIMB_HIGHBIT
   19103 	    definitions from "mpfr-gmp.h".
   19104 
   19105 	[src/mpfr-mini-gmp.h] GMP_NUMB_MASK is no longer needed.
   19106 
   19107 	[tests/random2.c] Removed a useless use of GMP_NUMB_MASK.
   19108 
   19109 	[src/div.c] In the case where the divisor has one limb (latest commit),
   19110 	check that the value of this limb fits in an unsigned long, otherwise
   19111 	mpfr_div_ui cannot be used. Indeed, according to the GMP manual 2.2,
   19112 	a limb may be a long long (actually unsigned):
   19113 	  For example in some 32-bit ABIs, GMP may support a limb as either a
   19114 	  32-bit `long' or a 64-bit `long long'.
   19115 	Note: if a limb is an unsigned long, this new test will be no-op, since
   19116 	always true.

   19122 2014-06-25  Vincent Lefvre  <vincent (a] vinc17.net>
   19123 
   19124 	[src/random_deviate.h] Fixed prototypes:
   19125 	  * Added __MPFR_DECLSPEC to avoid failure with Windows DLL; see
   19126 	    https://sympa.inria.fr/sympa/arc/mpfr/2014-06/msg00003.html
   19127 	  * Added _MPFR_PROTO for consistency (though it will probably
   19128 	    be removed in the near future).
   19129 	  * Removed variable names (coding style).
   19130 
   19131 2014-06-24  Vincent Lefvre  <vincent (a] vinc17.net>

   19151 	[src/sum.c] At Step 2, ignore the input bits of exponent >= maxexp.
   19152 
   19153 	[src/sum.c] Fixed maxexp2 update, and added truncflag for future

   19159 
   19160 	[src/sum.c] Added a TODO about carry propagation (so, it seems that
   19161 	using two windows may not really be that interesting to guarantee a

   19164 2014-06-17  Vincent Lefvre  <vincent (a] vinc17.net>

   19241 
   19242 	[tests/tpow.c] Removed comment that can now be confusing: try_mpfr.html
   19243 	was actually not using the mpfr_pow function, but exp(y*log(x)).
   19244 
   19245 	[tests/tpow.c] Added a test corresponding to buggy output on

   19485 	    It's better to guarantee a minimum of 10% increase; if the

   19525 	[doc/mpfr.texi] Updated the month.
   19526 
   19527 	Merged the set_exp branch into the trunk. Changes:
   19528 	  * src/mpfr-impl.h: updated the MPFR_SET_EXP(x, exp) definition for
   19529 	    the MPFR_EXP_CHECK case. There are 2 consequences:
   19530 	    1. The exp expression is evaluated several times (this should be
   19531 	       OK with the MPFR code and optimizations).
   19532 	    2. The real value of exp is tested for the assertion, instead of
   19533 	       the value converted to mpfr_exp_t. Thus new bugs could be found
   19534 	       (e.g. when an unsigned type is used instead of signed).
   19535 	  * src/set_exp.c: set the exponent only if x is a non-zero ordinary
   19536 	    number, i.e. already has a valid significand and a valid exponent
   19537 	    (thus it is no longer a low-level function, and it can no longer
   19538 	    generate an invalid value from a valid one).
   19539 	  * doc/mpfr.texi: updated mpfr_set_exp description and added an item
   19540 	    in the "API Compatibility / Changed Functions" section.
   19541 	  * Clean-up.

   19632 	non-representable value (detected due to the new MPFR_SET_EXP
   19633 	assertion check).
   19634 	Now, 87 tests pass and 82 tests fail on Linux/x86_64.
   19635 
   19636 	Updated src/urandomb.c due to the change of mpfr_set_exp behavior.
   19637 	Now, 77 tests pass and 92 tests fail on Linux/x86_64.
   19638 
   19639 	[tests/trandom.c] Improved test to get an assertion failure instead of
   19640 	a segmentation fault.
   19641 
   19642 	Start of mpfr_set_exp behavior clean-up.
   19643 	  * src/mpfr-impl.h: updated the MPFR_SET_EXP(x, exp) definition for
   19644 	    the MPFR_EXP_CHECK case. There are 2 consequences:
   19645 	    1. The exp expression is evaluated several times (this should be
   19646 	       OK with the MPFR code and optimizations).
   19647 	    2. The real value of exp is tested for the assertion, instead of
   19648 	       the value converted to mpfr_exp_t. Thus new bugs can be found
   19649 	       (e.g. when an unsigned type is used instead of signed).
   19650 	  * src/set_exp.c: set the exponent only if x is a non-zero ordinary
   19651 	    number, i.e. already has a valid significand and a valid exponent
   19652 	    (thus it is no longer a low-level function, and it can no longer
   19653 	    generate an invalid value from a valid one).
   19654 	  * doc/mpfr.texi: updated mpfr_set_exp description and added an item
   19655 	    in the "API Compatibility / Changed Functions" section.
   19656 	Currently 73 tests pass and 96 fail on Linux/x86_64, either due to bugs
   19657 	or due to code not yet updated for this change.
   19658 
   19659 	Set svn:ignore property on the tools/bench directory.

   19669 2014-02-05  Vincent Lefvre  <vincent (a] vinc17.net>
   19670 
   19671 	Removed MPFR_CHECK_MAX as it is now useless: all "max" tests succeed.
   19672 
   19673 	[src/lngamma.c] Fixed bug introduced in the latest change r8917
   19674 	(inexact was not initialized in the case compared < 0).

   19676 2014-02-04  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   19677 
   19678 	added code for large inputs in lngamma/lgamma

   19693 
   19694 	[src] Add constants:

   19718 2014-01-27  Vincent Lefvre  <vincent (a] vinc17.net>
   19719 
   19720 	[tools/mpfrlint] Run-time assertions concerning relations between
   19721 	the MPFR exponent type and the long type are allowed (see r8896).
   19722 
   19723 2014-01-26  Vincent Lefvre  <vincent (a] vinc17.net>
   19724 
   19725 	[tests/mpf_compat.h] In MPFR mode, skip the tests when mpfr_exp_t is not

   19727 
   19728 	[tests/tset_ld.c] Fixed printf argument.
   19729 
   19730 	[tests/tgamma.c] Fixed printf argument (bug detected with
   19731 	_MPFR_EXP_FORMAT=2 and -Werror=format=).
   19732 
   19733 	[tools/bench/mpfrbench.c] No longer use the numberof macro, and
   19734 	#include "mpfr.h" instead of "mpfr-impl.h", so that mpfrbench.c
   19735 	can now be linked against an installed MPFR library.
   19736 
   19737 2014-01-24  Vincent Lefvre  <vincent (a] vinc17.net>
   19738 
   19739 	Added MPFR_CHECK_GMP configure check.
   19740 	Useful if the user provides --with-gmp with a directory containing
   19741 	a GMP version that doesn't have the correct ABI: the previous tests
   19742 	won't trigger the error if the same GMP version with the right ABI
   19743 	is installed on the system, as this library is automatically
   19744 	selected by the linker, while the header (which depends on the ABI)
   19745 	of the --with-gmp include directory is used. Before this test, one
   19746 	was getting an error in MPFR_CHECK_DBL2INT_BUG, though the error is
   19747 	not related to a double-to-integer conversion bug.
   19748 
   19749 	[src/mpfr-impl.h] Corrections for the case _MPFR_EXP_FORMAT == 4:
   19750 	   * No longer use MPFR_EXP_MIN and MPFR_EXP_MAX unconditionally in
   19751 	     a #if directive, since if MPFR_HAVE_INTMAX_MAX is not defined,
   19752 	     the compilation fails. The test was not really useful anyway:
   19753 	     if one really wants mpfr_eexp_t to be long int if mpfr_exp_t
   19754 	     has the same range as long int, then _MPFR_EXP_FORMAT == 3 is
   19755 	     sufficient (and this is the default).
   19756 	   * Removed a test that should be always true due to the previous
   19757 	     inclusion of mpfr.h (intmax_t has already been used there in
   19758 	     the case _MPFR_EXP_FORMAT == 4).
   19759 
   19760 	[doc/README.dev] Rephrased paragraph added in r8897.
   19761 
   19762 	[doc/README.dev] Added a note for Automake 1.13+ and failed tests.
   19763 
   19764 	[src] Replaced some MPFR_ASSERTN's by MPFR_STAT_STATIC_ASSERT (from the
   19765 	detection by mpfrlint). Note: the MPFR_ASSERTN's concerning relations
   19766 	between the MPFR exponent type and the long type have not been replaced
   19767 	because these tests may fail with the non-standard _MPFR_EXP_FORMAT = 4
   19768 	on some platforms (e.g. 32-bit ones), and we still want to be able to
   19769 	build MPFR in this case in order to test it; this needs to be fixed.
   19770 
   19771 	[tools/mpfrlint] Constant checking in assertions.
   19772 
   19773 	[src/mpfr-mini-gmp.c] Use lower case for function parameters.

   19807 
   19808 	revert to EXTRA_PROGRAMS (bin_PROGRAMS is installed in /usr/local/bin,

   19966 
   19967 	[NEWS] Better Automake 1.13 support.
   19968 
   19969 	Merged the vl-am113 branch: test suite improvement with Automake 1.13.
   19970 	  * Moved GMP version check from tversion.c to the test_version()
   19971 	    function of tests.c, so that this check is done in every test.
   19972 	    This function now returns an int, as there are now 3 cases:
   19973 	    1. An error in MPFR version check is a fatal error: test_version()
   19974 	       exits with an error (exit status = 1).
   19975 	    2. An error in GMP version check is a non-fatal error: if there
   19976 	       are no errors in MPFR version check, test_version() returns
   19977 	       with value 1.
   19978 	    3. Otherwise test_version() returns with value 0 (everything is
   19979 	       fine).
   19980 	  * tversion.c still runs test_version(), but fails if this function
   19981 	    returns with an error, i.e. any error is fatal for this test.
   19982 	    Note: for the other tests, one just has a message in the output
   19983 	    in case of GMP version mismatch.
   19984 	  * mpfr-test.h: updated test_version() prototype.
   19985 	  * Makefile.am: removed the second tversion invocation, and output
   19986 	    the contents of tversion.log if this file exists (typically with
   19987 	    Automake 1.13+, for which one no longer gets tversion output by
   19988 	    default).
   19989 
   19990 	[tests/Makefile.am] Removed obsolete comment.

   20038 	[tests]
   20039 	  * Moved GMP version check from tversion.c to the test_version()
   20040 	    function of tests.c, so that this check is done in every test.
   20041 	    This function now returns an int, as there are now 3 cases:
   20042 	    1. An error in MPFR version check is a fatal error: test_version()
   20043 	       exits with an error (exit status = 1).
   20044 	    2. An error in GMP version check is a non-fatal error: if there
   20045 	       are no errors in MPFR version check, test_version() returns
   20046 	       with value 1.
   20047 	    3. Otherwise test_version() returns with value 0 (everything is
   20048 	       fine).
   20049 	  * tversion.c still runs test_version(), but fails if this function
   20050 	    returns with an error, i.e. any error is fatal for this test.
   20051 	    Note: for the other tests, one just has a message in the output
   20052 	    in case of GMP version mismatch.
   20053 	  * mpfr-test.h: updated test_version() prototype.
   20054 	  * Makefile.am: removed the second tversion invocation.
   20055 
   20056 	[tests/Makefile.am] Output the contents of tversion.log if this file
   20057 	exists (typically with Automake 1.13+, for which one no longer gets

   20274 	  * copied some of the version detection macros from mpfr-impl.h to

   20698 	select a compiler (before it may be chosen from __GMP_CC).
   20699 
   20700 	[configure.ac] The test of CC and CFLAGS was done too late! Moved this
   20701 	test earlier (checked on Debian/unstable with autoconf 2.69).

   20713 
   20714 2013-07-10  Vincent Lefvre  <vincent (a] vinc17.net>
   20715 
   20716 	[acinclude.m4] Corrected change in r8602 to get an error in the case

   20724 
   20725 	[src/exp_2.c] Fixed undefined behavior (present in all MPFR versions)

   20759 
   20760 	changed to allow compilation with C++:
   20761 	[src/random_deviate.h] must declare the types before extern C {...}
   20762 	[tests/tget_sj.c,tests/tset_si.c] "not" seems to be reserved in C++

   20764 2013-06-07  Vincent Lefvre  <vincent (a] vinc17.net>
   20765

   20767 	cannot have an internal underflow, thus is correct.
   20768 
   20769 2013-06-06  Vincent Lefvre  <vincent (a] vinc17.net>

   20783 	[src] Moved mp_bitcnt_t definition for GMP < 5 from mpfr-gmp.h to
   20784 	mpfr-impl.h (mpfr-gmp.h is only for definitions from GMP internals
   20785 	as it is included only in builds without GMP internals).
   20786 
   20787 	[src/mpfr-gmp.h] Fixed mp_bitcnt_t presence test.
   20788 
   20789 2013-06-06  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   20790

   20813 	[configure.ac] In AM_INIT_AUTOMAKE, lowered Automake version requirement
   20814 	to 1.11.2 (for AM_PROG_AR), as Ubuntu 12.04 LTS only has Automake 1.11.3
   20815 	(we assume that such distributions have a security patch).
   20816 
   20817 	[configure.ac] In AM_INIT_AUTOMAKE, require Automake 1.11.6 for
   20818 	AM_PROG_AR and security reasons.

   20847 	[src/random_deviate.c] Removed trailing spaces.
   20848 
   20849 	Added ar-lib to svn:ignore property (this script comes from Automake,
   20850 	due to the use of AM_PROG_AR in configure.ac as of r8546).
   20851 
   20852 2013-05-31  Vincent Lefvre  <vincent (a] vinc17.net>
   20853 
   20854 	[tests/memory.c] Added a FIXME comment about the time complexity of
   20855 	tests_memory_find (Paul Zimmermann noticed that tgrandom on a large
   20856 	value takes a lot of time, probably because of that).
   20857 
   20858 2013-05-31  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   20859 
   20860 	updated NEWS and contribution section in mpfr.texi

   20876 
   20877 	removed mpfr_grandom_alt (likewise previous commit)
   20878 
   20879 	removed mpfr_urandom_alt (slower than mpfr_urandom, but it can be recovered
   20880 	from the svn history to illustrate one of the basic properties of a newly
   20881 	initialized mpfr_random_deviate_t)
   20882 
   20883 	removed mpfr_random.h, headers are in mpfr.h

   20914 
   20915 	[src/vasprintf.c] Support all length modifiers defined by ISO C99, even if the

   20918 2013-05-24  Vincent Lefvre  <vincent (a] vinc17.net>
   20919

   20922 
   20923 2013-05-24  Philippe Thveny  <philippe.theveny (a] laposte.net>
   20924 
   20925 	[src/vasprintf.c] Always support 't' and 'L' length modifiers, but don't

   20945 
   20946 	replaced macros NPRINTF_T and NPRINTF_L by positive versions
   20947 	PRINTF_T and PRINTF_L, now we don't assume that %td and %Lf are supported
   20948 	when we don't check it (for example when cross-compiling, or under Windows
   20949 	when GMP is a dynamic library)
   20950

   20973 	[src/fits_intmax.c] Corrected a comment.
   20974 
   20975 	[src/{fits_u.h,fits_uintmax.c}] Fixed the mpfr_fits_u*_p functions,
   20976 	which incorrectly returned 0 ("doesn't fit") on negative arguments
   20977 	when the rounding to an integer was 0. The fits_uintmax.c file now
   20978 	uses fits_u.h for consistency.
   20979 
   20980 	[tests/tfits.c] Use error numbers to know where an error occurred.
   20981 
   20982 	[src/fits_uintmax.c] Replaced an obsolete comment by a TODO.
   20983 
   20984 	[tests/tget_sj.c] Added mpfr_get_uj tests on small negative op,

   20986 
   20987 	[tests/tset_si.c] Minor type correction for r8498 (this shouldn't matter
   20988 	because the value is normally small, but perhaps not in case of bug).
   20989 
   20990 	[tests/tset_si.c] Added mpfr_get_ui tests on small negative op.
   20991 
   20992 	[tests/tset_si.c] Corrected comment.
   20993 
   20994 	[doc/mpfr.texi] Updated the month.

   21264 		    (3) and the division was exact
   21265 		    In such a case the "reconstruction" of the ternary value was
   21266 		    inexact.
   21267 
   21268 2012-08-16  Vincent Lefvre  <vincent (a] vinc17.net>
   21269 
   21270 	[src/get_d64.c] mpfr_get_decimal64 was buggy in MPFR_RNDN on some

   21272 	  it was returning 0 instead of +/- 1e-398 (see r8370).

   21276 
   21277 	[src/get_d64.c] Fixed get_decimal64_max by simplifying it completely,

   21279 	Thanks to Rob (Sisyphus) for the idea.
   21280 
   21281 	[tests/tget_set_d64.c] Added overflow tests (they cover the two bad

   21283 
   21284 	[tests/tget_set_d64.c] Added some tests for large numbers.
   21285 
   21286 	Renamed WANT_ASSERT to MPFR_WANT_ASSERT in order to avoid a clash

   21305 	  HAVE_BIG_ENDIAN nor HAVE_LITTLE_ENDIAN is defined (currently an
   21306 	  error).
   21307 	[configure.ac] Fixed the use of AC_C_BIGENDIAN (since AC_CONFIG_HEADERS
   21308 	  is not used, one must have an ACTION-IF-UNIVERSAL argument).
   21309 	[doc/README.dev] Check with "-UHAVE_BIG_ENDIAN -UHAVE_LITTLE_ENDIAN"

   21311 
   21312 	[doc/README.dev] Update now that autogen.sh is in the repository.
   21313 
   21314 	Added autogen.sh sh script from Daniel Richard G. to install/update the
   21315 	autotools files and clean up caches (useful before a release).
   21316 
   21317 	Updated autotools files to get rid of obsolete macros (thanks to
   21318 	Daniel Richard G. for the patch; kept the autoconf requirement
   21319 	to 2.60 instead of changing it to 2.68 as done with autoupdate,
   21320 	since 2.60 seems to be sufficient according to the changes and
   21321 	2.68 is too recent, e.g. Debian/stable still has 2.67).
   21322 	--- Note ---
   21323 	This update has another effect: The "Configs for Windows DLLs."
   21324 	code (from "case $host in" to "esac") is now executed at the right
   21325 	time, after options like --disable-static are taken into account.

   21392 	Tested by replacing the macro tests in mpfr.h by just

   21797 
   21798 	[src/gamma.c] Completed the explanation concerning the new underflow

   21841 		      https://sympa.inria.fr/sympa/arc/mpfr/2012-04/msg00013.html
   21842 	Note (VL): this fix triggers an infinite loop on 32-bit machines
   21843 	  (or with -m32) in test20100709 from tgamma.c and this is partly

   21853 
   21854 	Added support for _Noreturn function specifier (ISO C11).
   21855 	  * acinclude.m4: define MPFR_HAVE_NORETURN if _Noreturn is supported.

   21893 
   21894 	[NEWS] New mpfr_flags_* functions.
   21895 
   21896 	Merged /trunk:r8141-8142 with a few manual changes due to conflict:
   21897 	replaced the flags-related mpfr_clear_* internal macros (which were
   21898 	already removed in this flags branch) by an uppercase version using
   21899 	a do-while in order to prevent one from using them in an expression.
   21900 	Renamed MPFR_SET_ERANGE to MPFR_SET_ERANGEFLAG for consistency.
   21901 
   21902 	[src/mpfr-impl.h] Improved comment about MPFR_CLEAR_* macros.
   21903 
   21904 	[src] Replaced the flags-related mpfr_clear_* internal macros by an
   21905 	uppercase version with a do-while in order to prevent one from using
   21906 	them in an expression. Renamed MPFR_SET_ERANGE to MPFR_SET_ERANGEFLAG
   21907 	for consistency.
   21908 
   21909 2012-04-19  Vincent Lefvre  <vincent (a] vinc17.net>
   21910 
   21911 	Implemented the mpfr_flags_* functions (and mpfr_flags_test as a macro).
   21912 	The MPFR_FLAGS_* macros had to be moved from mpfr-impl.h to mpfr.h (as
   21913 	they are now part of the API). Check that MPFR_FLAGS_ALL <= INT_MAX (or
   21914 	similar) when need be. Removed the mpfr_clear_* macros and merged r8139
   21915 	(about the MPFR_SET_ERANGE macro) from the trunk due to a risk to break
   21916 	the sequence point rules.
   21917 
   21918 	[src/mpfr-impl.h] Use a do-while statement for the MPFR_SET_ERANGE()
   21919 	macro in order to prevent one from using this macro in an expression,
   21920 	as the sequence point rules could be broken if __gmpfr_flags is
   21921 	assigned twice in the same expression (via macro expansions).
   21922 	Note: This cannot be done for the mpfr_clear_* flags macros because
   21923 	we want to be able to follow the API inside MPFR (thus these macros
   21924 	must be usable wherever a function is). These macros should probably
   21925 	be removed or renamed in the future (e.g. via the flags branch).
   21926 
   21927 2012-04-17  Vincent Lefvre  <vincent (a] vinc17.net>
   21928

   21938 	[doc/mpfr.texi] Updated "API Compatibility" section: functions
   21939 	mpfr_fmodquo, mpfr_fpif_export and mpfr_fpif_import are new in
   21940 	MPFR 3.2.
   21941

   21953 
   21954 2012-03-26  Vincent Lefvre  <vincent (a] vinc17.net>
   21955 
   21956 	[src] New mpfr_flags_t type, defined as an unsigned int. For the
   21957 	  __gmpfr_flags variable and internal flags-related variables,
   21958 	  replaced unsigned int by mpfr_flags_t (note that this doesn't
   21959 	  change the ABI, since unsigned int was already used).
   21960 	[tests] Cast __gmpfr_flags to unsigned int when printed with %u.
   21961 
   21962 2012-03-26  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   21971 	[tests/tests.c] Improved src_fopen() a bit.
   21972 
   21973 	[doc/README.dev] Explain the use of the new MPFR_DBGRES macro.
   21974 
   21975 	[src/mpfr-impl.h] Added a MPFR_DBGRES macro to avoid a warning in
   21976 	non-debug mode, e.g. with GCC's -Wunused-but-set-variable, when a
   21977 	result is tested only in an MPFR_ASSERTD expression.
   21978 	[src/const_euler.c] Avoid such a warning by using MPFR_DBGRES.
   21979 
   21980 	MPFR_ASSERTD or MPFR_ASSERTN must be used for assertions, not ASSERT.

   22134 	[INSTALL] Added information about --with-sysroot.
   22135 
   22136 	[INSTALL] Removed an obsolete paragraph saying that the test suite

   22149 
   22150 2012-03-05  Vincent Lefvre  <vincent (a] vinc17.net>
   22151 
   22152 	[src/mpfr.h] Minor change to be consistent with "src/mpfr-gmp.h".
   22153 
   22154 	[src/mpfr.h] Added a reference to MPFR bug 13947.
   22155 
   22156 	[src/mpfr.h] Simple temporary fix following GMP's internal __gmp_const
   22157 	macro removal in <https://gmplib.org/repo/gmp/rev/d287cfaf6732> (and its
   22158 	replacement by const): if __gmp_const isn't define, let's define it to
   22159 	const.
   22160 
   22161 2012-03-03  Vincent Lefvre  <vincent (a] vinc17.net>

   22164 
   22165 2012-02-27  Vincent Lefvre  <vincent (a] vinc17.net>
   22166 
   22167 	[configure.ac] If 'gmp.h' and 'libgmp' seem to have different versions,
   22168 	output the temporary LD_RUN_PATH value (may be useful for debugging).
   22169 
   22170 2012-02-24  Vincent Lefvre  <vincent (a] vinc17.net>
   22171 
   22172 	[tests] Removed #include of headers already included via "mpfr-test.h"
   22173 	(<limits.h>, <stdio.h>, <stdlib.h>). Note: this change doesn't apply
   22174 	to tvalist.c, which is a special test that doesn't use "mpfr-test.h".
   22175 
   22176 	[src] #include <stdlib.h> unconditionally in mpfr-impl.h; removed
   22177 	this #include from the .c files.
   22178 
   22179 	[src/logging.c] #include <stdarg.h> was no longer necessary. Removed.
   22180 
   22181 	[src/logging.c] Updated a comment (contained obsolete information).
   22182 
   22183 	[src/mpfr-impl.h] Use %.*Rg instead of %.*Rf for MPFR_LOG_VAR.
   22184 
   22185 	[NEWS] Mention an internal change in MPFR 3.1.0.
   22186 
   22187 	Corrected a typo in MPFR_LOG_FUNC of add_d.c, add_ui.c and mul_d.c
   22188 	(mpfr_get_prec  mpfr_log_prec), fixing bug 13933.
   22189 	The consequence was random freezes (on the same binary) with dynamic
   22190 	linking (and just more memory with static linking to the MPFR library)
   22191 	when logging was used.
   22192 
   22193 	[src/const_euler.c] Use the safer MPFR_BLOCK.
   22194 
   22195 2012-02-23  Vincent Lefvre  <vincent (a] vinc17.net>
   22196 
   22197 	[src/const_euler.c] Removed a useless log message added in r8040.
   22198 
   22199 	[src/const_euler.c] Replaced computations on double by computations
   22200 	  on MPFR types, with detection of overflows. Fixed inconsistencies
   22201 	  with algorithms.tex (due to rounding) in the computation of n.
   22202 	[src/mpfr-impl.h] Removed #define ALPHA (no longer used).
   22203 
   22204 	[src/mpfr-impl.h] Removed obsolete #define EXPM1.
   22205 
   22206 	[src/erf.c] Removed an obsolete #define.
   22207 
   22208 	[BUGS] Update concerning huge precisions and integer overflows.
   22209 
   22210 	[examples/version.c] Output mpfr_prec_t information with all MPFR
   22211 	versions. Output signedness information for MPFR types/macros.
   22212 
   22213 	[src/mpfr.h] Decrease the MPFR_PREC_MAX value by 256 in order to
   22214 	  avoid some integer overflows in existing code that increases the
   22215 	  working precision (if mpfr_prec_t is on 64 bits, this does not
   22216 	  change anything in practice), as too large precisions should be
   22217 	  detected via assertions for more security. After discussion, it
   22218 	  has been decided to keep the MPFR_PREC_MAX value close to 2^31
   22219 	  when mpfr_prec_t is on 32 bits.
   22220 	[src/mpfr-impl.h] Added a comment concerning MPFR_ADD_PREC.
   22221 
   22222 	[examples/version.c] Output more information about the precision and
   22223 	exponent types.
   22224 
   22225 2012-02-22  Vincent Lefvre  <vincent (a] vinc17.net>
   22226 
   22227 	[src/mpfr-impl.h] Use MPFR_ADD_PREC in MPFR_ZIV_NEXT.
   22228 
   22229 	[src/mpfr-impl.h] Added an MPFR_ADD_PREC macro to safely increase some
   22230 	  precision (i.e. with an assertion check for integer overflow).
   22231 	[src/ai.c] Use this MPFR_ADD_PREC macro, in particular in a case where
   22232 	  the additional precision can be huge.
   22233 	TODO: Other files would need to use MPFR_ADD_PREC.
   22234 
   22235 	[tests/tinits.c] Updated the large precision test to trigger a bug fixed
   22236 	in r8025 on 32-bit machines (or when MPFR is built with -m32). Here the
   22237 	crash was due to (MPFR_PREC (b) + GMP_NUMB_BITS-1)/GMP_NUMB_BITS in
   22238 	"src/set.c".
   22239 
   22240 	[src/rec_sqrt.c] Removed useless #include (mpfr-impl.h does a better job
   22241 	for stdio).
   22242 
   22243 	[tests/tinits.c] Improved r8026 (missing #include, support 16-bit prec).
   22244 
   22245 	Document the MPFR_DEBUG_BADCASES environment variable before bad_cases()
   22246 	in tests/tests.c (where it is used). Remove it from "doc/README.dev"
   22247 	since it is useful only in case of crash / infinite loop in bad_cases(),
   22248 	and will give useless output otherwise.

   22256 
   22257 2012-02-22  Vincent Lefvre  <vincent (a] vinc17.net>
   22258 
   22259 	Avoid potential integer overflows and improve consistency. This should
   22260 	fix bug #13918 "Segfault with precision = MPFR_PREC_MAX on 32-bit".
   22261 	Note: this problem appeared in MPFR 3.0.0 when the precision type (now
   22262 	mpfr_prec_t) was changed to a signed integer.
   22263 
   22264 	[configure.ac] Added a comment mentioning a problem with GNU gold ld.

   23012 
   23013 	[src/{mpfr.h,mpfr-impl.h,vasprintf.c}] Clean-up and improvement
   23014 	of definitions related to mpfr_exp_t. MPFR can now be built with

   23017 
   23018 	[src/mpfr.h] Fixed spaces in a comment.
   23019

   23021 	(or unsigned long).
   23022 	[merged changeset r7643 from the exp-int branch]
   23023 
   23024 	[src/strtofr.c] Support the case where mpfr_exp_t < long; mpfr_exp_t is
   23025 	currently defined as mp_exp_t, which comes from GMP, and GMP currently
   23026 	defines mp_exp_t as a long, except on Cray (never tested for MPFR). But
   23027 	this may change in the future (possibly as an option)...
   23028 	[merged changeset r7642 from the exp-int branch]

   23033 	[tests/tpow_z.c] More details for a test in case of failure.
   23034 
   23035 	[src/sub1.c] Fixed several bugs: integer overflows and potential
   23036 	out-of-bound pointers. They might be visible on particular platforms,
   23037 	with a particular configuration (e.g. 64-bit limbs and 32-bit exponent
   23038 	type) or particular compiler options (to check such overflows).
   23039 	[merged changesets r7637-7638 from the exp-int branch]
   23040 
   23041 2011-05-11  Vincent Lefvre  <vincent (a] vinc17.net>
   23042 
   23043 	[tests/tsin.c] Added a test (it failed before the fix in r7308).
   23044 
   23045 	Fixed constants pi and log(2) computation when logging is used: When
   23046 	MPFR is built with logging support, these two constants are used by
   23047 	the logging functions (via mpfr_fprintf, then mpfr_log, for the base
   23048 	conversion). Since the mpfr_cache function isn't re-entrant when
   23049 	working on the same cache, we need to define two caches for each
   23050 	constant. Otherwise the constants could be incorrect; for instance,
   23051 	"MPFR_LOG_ALL=1 ./tconst_pi" was failing.
   23052 	Note: the bug was introduced with the new logging system from r7575
   23053 	for MPFR 3.1.0, based on mpfr_fprintf instead of mpfr_out_str (which
   23054 	doesn't depend on mpfr_log).
   23055 
   23056 2011-05-09  Vincent Lefvre  <vincent (a] vinc17.net>
   23057 
   23058 	[tests/tests.c] Replaced atoi by strtoul to read the seed from
   23059 	GMP_CHECK_RANDOMIZE, as it is an unsigned long.
   23060 
   23061 	[tests/texp.c] Fixed the test comparing mpfr_exp_2 and mpfr_exp_3:
   23062 	filter out 0, as it is handled correctly only by mpfr_exp.
   23063 
   23064 2011-05-06  Vincent Lefvre  <vincent (a] vinc17.net>

   23076 	[src/atan.c] Fixed bug in mpfr_atan: mpfr_check_range was called on the
   23077 	unrounded result (no longer allocated) instead of the rounded result.
   23078 	Consequence of this bug: possible incorrect or invalid result and/or
   23079 	incorrect flags if either the unrounded result or rounded result is not
   23080 	in the current exponent range. Or possibly worse if the memory used by
   23081 	the unrounded result is modified before the return of the function.
   23082 
   23083 	[tests/tatan.c] Corrected a comment.
   23084 
   23085 	[tests/tatan.c] Added a testcase showing a failure of mpfr_atan

   23101 
   23102 	[src/mul.c] Updated the FIXME comment.
   23103 
   23104 	Bug in mpfr_mul: a call mpfr_mulhigh_n(pointers..., n) where n is some

   23107 	  * [src/mul.c] Added a FIXME comment.
   23108 	  * [tests/tmul.c] Added a corresponding test. The result is not checked

   23163 
   23164 	[tests/trint.c] Removed a useless pointer cast (in general, such casts
   23165 	are either useless or incorrect, as breaking aliasing rules).

   23220 
   23221 	[configure.ac] Removed the -Wno-format GCC option, which was added

   23231 	(e.g. mpfr_pow(x,x,y,rnd) or mpfr_pow(y,x,y,rnd)) and the result is
   23232 	negative, thus when x is negative and y is a huge odd integer ("huge"
   23233 	because not-too-large integers are currently handled by mpfr_pow_z).

   23255 
   23256 	[src/pow_z.c] Fixed bug bug20110320, that occurs in extremely reduced

   23272 
   23273 	[NEWS] Added a note about the fix in the mpfr_subnormalize

   23276 
   23277 	Completed r7575 (Get rid of deprecated register_printf_function
   23278 	function in logging system): there was a remaining old MPFR_LOG_FUNC
   23279 	in "src/div_ui.c". Now, the MPFR source no longer contains '%#R'.

   23293 	is larger than a long.
   23294 
   23295 	[tests/terf.c] Added some tests of the flags (no failure in them,
   23296 	thanks to the mpfr_cmp_si (x, -27282) in erfc.c, for 1b).
   23297 
   23298 	[tests/tgeneric.c] In failure messages, output the name of the
   23299 	tested function. This is useful for programs that have generic
   23300 	tests for several functions, such as terf.
   23301 
   23302 	[tests/terf.c] Added a testcase showing a failure due to bad flags

   23310 
   23311 	[src/erfc.c] Added an assertion for future platforms (e.g. with 128-bit

   23319 
   23320 	[erfc.c] fixed bug found by Pascal Molin: when we increase the exponent range

   23322 
   23323 2011-03-10  Vincent Lefvre  <vincent (a] vinc17.net>
   23324 
   23325 	[src/jn.c] Fixed the MPFR_FAST_COMPUTE_IF_SMALL_INPUT test for n == 1
   23326 	in underflow cases.
   23327

   23329 
   23330 	[src/jn.c] Check that no intermediate underflow or overflow occurs.
   23331 
   23332 	[doc/algorithms.tex] For the Bessel function, say that the algorithm
   23333 	assumes that no underflows/overflows occur.
   23334 
   23335 2011-03-09  Vincent Lefvre  <vincent (a] vinc17.net>
   23336 
   23337 	[src/gamma.c] More robust code (for the change in r7551).
   23338 
   23339 	Removed trailing spaces.
   23340 
   23341 	[tests/tgeneric.c] Added feature for MPFR_SUSPICIOUS_OVERFLOW to avoid
   23342 	spurious failures by defining TGENERIC_SO_TEST to some well-chosen test.
   23343 
   23344 	[tests/tgamma.c] Added a comment about MPFR_SUSPICIOUS_OVERFLOW.
   23345 
   23346 	[src/gamma.c] Fixed the special code for tiny values.
   23347 
   23348 	[tests/tgamma.c] Corrected a test and added other tests for tiny x > 0.
   23349 
   23350 	[tests/tgamma.c] Updated a comment.
   23351 
   23352 	[tests/tgamma.c] Restore emax.

   23354 	[tests/tgamma.c] Do not initialize x twice.
   23355 
   23356 	[tests/tgamma.c] Do not run the same test twice if emin = MPFR_EMIN_MIN.
   23357 
   23358 	[tests/tgamma.c] Added tests for tiny values, showing bugs in special
   23359 	code for such values. Run tgamma with at least an argument to get all
   23360 	the failures.
   23361 
   23362 2011-03-07  Vincent Lefvre  <vincent (a] vinc17.net>
   23363 
   23364 	[src/jn.c] Fixed mpfr_jn_k0() internal function:
   23365 	  * The prototype was incorrect: one needs "unsigned long" for n
   23366 	    (actually absn), in case absn is equal to - LONG_MIN.
   23367 	  * The formula and the code were incorrect for n = 0, due to the
   23368 	    division by n; it was yielding k0 = ULONG_MAX. The case n = 0
   23369 	    is now handled separately.
   23370 	  * Small optimization: division by log(2) -> multiplication by
   23371 	    1/log(2).
   23372 
   23373 	[src/jn.c] Avoid integer overflow in the computation of the initial
   23374 	working precision. This makes several tests fail, but logging shows
   23375 	that previous non-failure was due to undefined behavior due to huge
   23376 	k0 computed by mpfr_jn_k0.
   23377 
   23378 	[src/jn.c] Added a comment for mpfrlint.
   23379 
   23380 	[tools/mpfrlint] Change of r7515: any mpfr_clear_* can be mentioned.
   23381 
   23382 	[src/jn.c] Added comments and fixed a bug.
   23383 
   23384 	[src/jn.c] Detect incorrect error analysis (that may have been the goal
   23385 	of the assertion corrected in r7534, but this wasn't documented). Added
   23386 	a FIXME comment.
   23387 
   23388 	[src/jn.c] Fixed incorrect assertion. It could occur only
   23389 	in precision >= 2^(1+s/2), where s is the bitsize of a
   23390 	"long", e.g. p >= 2^17 = 131072 on most 32-bit machines and
   23391 	p >= 2^33 = 8,589,934,592 on most 64-bit machines. Only some
   23392 	arguments are affected (|z| between around 2^(s/2) and p/2).
   23393 
   23394 	[tests/Makefile.am] Added a comment.
   23395 
   23396 	[doc/README.dev] Corrected a typo.

   23411

   23430 
   23431 	[src/add.c,src/sub.c] Split assertions for C90 compilers, to avoid

   23434 
   23435 	[src/yn.c] Minor change.
   23436 
   23437 	[src/yn.c] Extend the exponent range (code not checked concerning
   23438 	internal exceptions, such as overflows, underflows and divby0).
   23439 
   23440 	[src/agm.c] Added comments (for mpfrlint, in particular).
   23441 
   23442 	[tools/mpfrlint] The use of mpfr_overflow_p, etc. is allowed if
   23443 	mpfr_clear_flags is mentioned (useful for checking purpose at the
   23444 	end of a function, but this needs an explicit mpfr_clear_flags;
   23445 	otherwise MPFR_BLOCK should still be used).
   23446 
   23447 	[src/agm.c] Completed scaling to avoid intermediate overflow/underflow.
   23448 
   23449 	[src/agm.c] Bug fix in error computation: in Ziv's iteration, err kept

   23451 	Consequence: a possible loss of performance in rare cases.
   23452 
   23453 	[src/cmp2.c] Removed a useless assertion and updated comments.

   23463 
   23464 	[src/agm.c] Implemented scaling to avoid intermediate overflow/underflow
   23465 	(but the tagm test still fails, due to a rounding error this time).
   23466 
   23467 	[tests/tagm.c] Added tests triggering intermediate underflow/overflow.

   23471 	[tests/tagm.c] Corrected values (using Pari).
   23472 
   23473 	[src/agm.c] Extend the exponent range. This doesn't make the algorithm

   23986 	Added exp-int branch from r7304, where mpfr_exp_t is defined as an
   23987 	int instead of mp_exp_t. This is for testing only for usual 64-bit
   23988 	machines (e.g. x86_64 GNU/Linux), where mpfr_exp_t and mpfr_prec_t
   23989 	are now on 32 bits instead of 64 bits. Many tests currently fail

   24032 
   24033 	[configure.ac] With --with-gmp-build, do not duplicate the include
   24034 	search paths if the GMP source and build directories are the same.
   24035 
   24036 	[configure.ac] Fixed another bug in r7289. This new version now seems
   24037 	to work with GMP's srcdir pointing to a relative directory or to an

   24053 	with Patrick and Paul).
   24054 
   24055 	[configure.ac] Fixed two problems with --with-gmp-build:
   24056 	  * "grep -w" isn't POSIX (an error shouldn't matter with recent GMP
   24057 	    versions, as CFLAGS and CC would then be retrieved from gmp.h).

   24293 	differ.
   24294 
   24295 	Note: the message does not automatically imply the problem; however, if the
   24296 	message appears, the ABI somehow differ, so it is worth mentioning it.

   24414 
   24415 	[src/sqrt.c] followup to previous commit: only compute an extra limb of the
   24416 		     square root for rounding to nearest (for directed rounding, it
   24417 		     suffices to know if the remainder is zero or not)
   24418 
   24419 	[src/sqrt.c] now uses mpn_rootrem (if available) instead of mpn_sqrtrem since
   24420 		     mpn_rootrem is faster. Also refactored the code: now compute one
   24421 		     more limb of the square root when the target precision is a
   24422 		     multiple of GMP_NUMB_LIMB. This greatly simplifies the code.
   24423

   24448 	[mulders.c] use mpn_lshift instead of mpn_add_n, and improved the default

   24454 	[tuneup.c] changed lower bound for exp_2 threshold from MPFR_PREC_MIN (2) to
   24455 		   GMP_NUMB_BITS. Seems to be better (since for p=2 the 2nd routine
   24456 		   was sometimes already faster).
   24457 
   24458 	[mul.c] another changes for Mulders' algorithm in case of a square

   24556 	[src/mpfr.h] Added casts to improve robustness in case of undefined

   24566 	are OK since if X is a constant expression, then (unsigned long) X is

   24629 2010-08-19  Vincent Lefvre  <vincent (a] vinc17.net>
   24630 
   24631 	[src/gmp_op.c] The function mpfr_cmp_z could fail in a reduced
   24632 	exponent range.
   24633 	[tests/tgmpop.c] Added a corresponding testcase.
   24634 
   24635 	[src/gmp_op.c] The functions mpfr_mul_z, mpfr_div_z, mpfr_add_z and
   24636 	mpfr_sub_z could fail in a reduced exponent range. Fixed.
   24637 	[tests/tgmpop.c] Added corresponding testcase.
   24638 
   24639 2010-08-18  Vincent Lefvre  <vincent (a] vinc17.net>
   24640 
   24641 	[tests/tgmpop.c] Disabled buggy tests.
   24642 
   24643 	[src/gmp_op.c] Fixed the intermediate overflow case in mpfr_muldiv_z
   24644 	(for mpfr_mul_q and mpfr_div_q).
   24645 
   24646 	[src/gmp_op.c] Added function mpfr_muldiv_z (currently static -- should
   24647 	it be in the API?) that computes y = RND(x*n/d), where n and d are mpz
   24648 	integers. Changed mpfr_mul_q and mpfr_div_q to use this function.
   24649 	Note: the code of the general case is currently the same as the old
   24650 	mpfr_mul_q/mpfr_div_q code, thus needs to be fixed.
   24651 
   24652 	[tests/tgmpop.c] Replaced GMP_RNDN by MPFR_RNDN.
   24653 
   24654 	[tests/tgmpop.c] Added testcase for mpfr_mul_q/mpfr_div_q bug noted
   24655 	in src/gmp_op.c (due to intermediate overflow).
   24656 
   24657 2010-08-17  Vincent Lefvre  <vincent (a] vinc17.net>
   24658 
   24659 	[src/logging.c] Added a comment about register_printf_function.
   24660 
   24661 	Added tools/ck-version-info Perl script with the same license as
   24662 	Makefile.am, to check consistency concerning -version-info and
   24663 	that the -version-info value is up-to-date.
   24664 	Updated Makefile.am:
   24665 	  * In dist-hook, replaced complex sh code by a call to ck-version-info.
   24666 	  * Distribute ck-version-info (EXTRA_DIST).
   24667 
   24668 	Updated svn:ignore properties.
   24669 
   24670 	[Makefile.am] Put tools/get_patches.sh back to EXTRA_DIST.
   24671 
   24672 	[src/Makefile.am] Fixed -version-info (I forgot to increment CURRENT).
   24673 
   24674 2010-08-17  Vincent Lefvre  <vincent (a] vinc17.net>
   24675 
   24676 	Source reorganization. In short:
   24677 	  * Added directories and moved related files into them:
   24678 	      - src for the MPFR source files (to build the library).
   24679 	      - doc for documentation files (except INSTALL, README...).
   24680 	      - tools for various tools (scripts) and mbench.
   24681 	      - tune for tuneup-related source files.
   24682 	      - other for other source files (not distributed in tarballs).
   24683 	    Existing directories:
   24684 	      - tests for the source files of the test suite (make check).
   24685 	      - examples for examples.
   24686 	      - m4 for m4 files.
   24687 	  * Renamed configure.in to configure.ac.
   24688 	  * Added/updated Makefile.am files where needed.
   24689 	  * Updated acinclude.m4 and configure.ac (AC_CONFIG_FILES line).
   24690 	  * Updated the documentation (INSTALL, README, doc/README.dev and
   24691 	    doc/mpfr.texi).
   24692 	  * Updated NEWS and TODO.
   24693 	  * Updated the scripts now in tools.
   24694 
   24695 	The following script was used:
   24696 
   24697 	#!/usr/bin/env zsh
   24698 	svn mkdir doc other src tools tune
   24699 	svn mv ${${(M)$(sed -n '/libmpfr_la_SOURCES/,/[^\]$/p' \

   24701 	       round_raw_generic.c jyn_asympt.c src
   24702 	svn mv mbench check_inits_clears coverage get_patches.sh mpfrlint \
   24703 	  nightly-test update-patchv update-version tools

   24709 	svn cp Makefile.am src/Makefile.am
   24710 	svn rm replace_all
   24711 	[Modifying some files, see above]
   24712 	svn add doc/Makefile.am
   24713 	svn add tune/Makefile.am

   24715 2010-08-16  Vincent Lefvre  <vincent (a] vinc17.net>
   24716 
   24717 	[Makefile.am] Updated -version-info (the interface hasn't really been
   24718 	changed yet -- though the future bug fix / rewrite of mpfr_mul_q and
   24719 	mpfr_div_q could be seen as an addition -- but this eases maintenance
   24720 	and avoids -version-info conflict with the 3.0 branch).
   24721 
   24722 	[bidimensional_sample.c] Added copyright notice.
   24723 
   24724 	[ai.c] Prototype clean-up.
   24725 
   24726 2010-08-16  Vincent Lefvre  <vincent (a] vinc17.net>
   24727 
   24728 	Avoid a compilation failure on OSF/1 (Tru64) 5.1 due to non-C99
   24729 	conformance though <inttypes.h> is available. In various source
   24730 	files and m4 files, use the following form only:
   24731 
   24732 	#if HAVE_INTTYPES_H
   24733 	# include <inttypes.h>
   24734 	#endif
   24735 	#if HAVE_STDINT_H
   24736 	# include <stdint.h>
   24737 	#endif
   24738 
   24739 	Updated README.dev to mention this form.
   24740 
   24741 2010-08-13  Vincent Lefvre  <vincent (a] vinc17.net>
   24742 
   24743 	[tests] Avoid warning due to -Wunused-but-set-variable (from future
   24744 	GCC 4.6). Only let the one from tsubnormal.c because it's a TODO.
   24745 	  * mpf_compat.h: use the variables, that are there for prototype
   24746 	    checking.
   24747 	  * tpow.c, tpow_z.c: test the ternary value.
   24748 	  * tremquo.c: removed inex variables (the bug due to the MPFR value).
   24749 	  * tset.c: test the ternary value.
   24750 	  * tset_ld.c: removed the long double variable (it cannot be tested
   24751 	    in a portable way and the bug was an assertion failure).
   24752 	  * tzeta_ui.c: removed the inexact variable (not really useful here).
   24753 
   24754 	[get_f.c] Avoid warning due to -Wunused-but-set-variable (from
   24755 	future GCC 4.6).
   24756 
   24757 	[gamma.c] Avoid warning due to -Wunused-but-set-variable (from
   24758 	future GCC 4.6).
   24759 
   24760 	[gmp_op.c] Avoid warning due to -Wunused-but-set-variable (from

   24762 
   24763 	[exp_2.c] No longer define qn and sizer, which are no longer used since
   24764 	r6919. This was detected by gcc-snapshot (4.6.0 prerelease) under Debian
   24765 	(-Wunused-but-set-variable).
   24766 
   24767 	[NEWS] Update.
   24768 
   24769 	[ieee_floats.h] Avoid breaking aliasing-rules when _GMP_IEEE_FLOATS is
   24770 	defined (e.g. with --with-gmp-build), by replacing a struct by a union
   24771 	like in r6381 for long double.
   24772 
   24773 	[configure.in] Removed useless slash.
   24774 
   24775 2010-08-12  Vincent Lefvre  <vincent (a] vinc17.net>
   24776

   24780 
   24781 	[update-version] Detect errors.
   24782 
   24783 	Updated FAQ.html with update-faq.
   24784 
   24785 	[faq.xsl] Do not copy XML comments.
   24786 
   24787 	Updated FAQ.html with update-faq.
   24788 
   24789 	[README.dev] INRIAGforge -> INRIAGForge.
   24790 
   24791 	[README] Update:
   24792 	  * InriaGforge -> INRIAGForge (official typography).
   24793 	  * Updated URL of the Subversion FAQ (now on apache.org).
   24794 	  * README.dev provided via SVN only.
   24795 	  * Removed the old note about the old CVS repository.

   24800 
   24801 	[tests/tgmpop.c] Added missing "static".
   24802 
   24803 2010-08-11  Philippe Thveny  <philippe.theveny (a] laposte.net>
   24804

   24806 
   24807 2010-08-04  Vincent Lefvre  <vincent (a] vinc17.net>
   24808 
   24809 	README.dev: updated "To make a release" (test of FP division by 0).
   24810 
   24811 	Support implementations where the floating-point division by 0 fails.
   24812 	  * acinclude.m4: added a test to check whether the FP division by 0
   24813 	    fails, and define MPFR_ERRDIVZERO in such a case.
   24814 	  * tests/tests.c: if MPFR_TEST_DIVBYZERO is defined, test whether
   24815 	    there has been a floating-point division by 0 (FE_DIVBYZERO or
   24816 	    FE_INVALID exception).
   24817 	  * tests/tgeneric.c: if MPFR_ERRDIVZERO is defined, disable the
   24818 	    huge and tiny cases.
   24819 	  * tests/t*_{flt,d,ld}.c: if MPFR_ERRDIVZERO is defined, disable
   24820 	    tests involving NaN and infinities.
   24821 
   24822 	[README.dev] Update about the compilers.
   24823

   24825 
   24826 	[get_sj.c] Fixed bug found by John Regehr:
   24827 	https://gforge.inria.fr/tracker/index.php?func=detail&aid=10839&group_id=136&atid=619
   24828 	Note: the problem was an undefined behavior that could occur when
   24829 	sizeof(mp_limb_t) < sizeof(intmax_t) and |x| was small enough,
   24830 	because a right shift was >= the type width. However as the shifted
   24831 	value was 0, most platforms should not be affected by this bug. This
   24832 	problem was detected with clang -fcatch-undefined-ansic-behavior.
   24833 
   24834 	[tests/tget_sj.c] Added tests of 1 and -1.
   24835

   24838 
   24839 	[configure.in] When logging is enabled, remove the possible -pedantic
   24840 	from GMP's CFLAGS to avoid warnings about C conformance.
   24841 
   24842 	[mpfr-impl.h] Reverse-merged changeset r7042. The code was not
   24843 	incorrect: the warning is due to the -pedantic from GMP's CFLAGS.
   24844 
   24845 	[mpfr-impl.h] Correction to avoid GCC warnings
   24846 	  warning: invalid storage class for function 'x_f'

   24868 	(svn merge -r7032:7031 mparam_h.in)
   24869 
   24870 	[Makefile.am] Added "BUILT_SOURCES = mparam.h", fixing bug

   24906 
   24907 	Updated bidimensional_sample to take into account the fact the mpfr_ai1 and mpfr_ai2 are now statically defined.
   24908 
   24909 	mpfr_ai1 and mpfr_ai2 are now declared static. Only mpfr_ai is global.

   24913 2010-07-20  Sylvain Chevillard  <Sylvain.Chevillard (a] inria.fr>

   24915 	Added automatic tuning of mpfr_ai.
   24916 
   24917 	More precisely:
   24918 	* removed ai2.c: both implementations are now in the same file ai.c
   24919 	* added thresholds and automatic choice of the method to use in function of the thresholds.
   24920 	* added procedures for tuning functions like ai into tuneup.c
   24921 	* added a tuning procedure into tuneup.c

   24954 
   24955 	[exp_2.c] added 3 more bits to initial working precision. On a sample of 20247
   24956 		  tests by Sylvain Chevillard with precisions in [50, 100], the number
   24957 		  of Ziv's failures decreased from 1184 to 144, which is less than 1%
   24958 		  (to reduce to zero, we would have to increase the number of extra

   24968 
   24969 	[acinclude.m4] Use AC_FUNC_ALLOCA to have HAVE_ALLOCA_H defined
   24970 	when available. This problem was introduced when AC_FUNC_ALLOCA
   24971 	was removed from configure.in in r6765. Note: building MPFR with

   24973 
   24974 	[mpfr-gmp.h] Reverted incorrect changeset r6987 (see code about alloca).

   25036 
   25037 	[exp_2.c] fixed inefficiency for large x: the initial precision was too small,
   25038 		  which had the effect that the first Ziv iteration did fail with
   25039 		  non-negligible probability (problem reported by Sylvain Chevillard).
   25040 		  Also in case of 2 iterations or more the K variable was corrupted.
   25041 	Note (2012-03-03): huge inefficiency has been noticed when evaluating
   25042 	mpfr_exp on an argument close to log(2^n) in RNDU:
   25043 	  https://sympa.inria.fr/sympa/arc/mpfr/2012-03/msg00000.html
   25044 	One has an obvious hard-to-round case, meaning that several iterations
   25045 	are needed and that K is corrupted. This changeset fixes this bug.

   25136 		  The fix is not optimal in the sense that GMP does not give a bound
   25137 		  on the allocated memory, thus we can only guess.

   25350 	[mpfr.texi, NEWS] Noted that the mpfr_ai implementation is incomplete
   25351 	and experimental.
   25352 
   25353 	[ai.c] Use MPFR_IS_SINGULAR. Added a FIXME comment for Ai(0).

   25355 	Type corrections for C++ compilers (in particular, mpfr_rnd_t vs int).
   25356

   25391 
   25392 2010-05-18  Sylvain Chevillard  <Sylvain.Chevillard (a] inria.fr>
   25393 
   25394 	* I added a new implementation of Airy Ai. This implementation uses Smith's
   25395 	algorithm.
   25396 	Currently, it is provided as a separate implementation mpfr_ai2.
   25397 
   25398 	* Please note that both mpfr_ai and mpfr_ai2 need to efficiently evaluate
   25399 	Gamma(1/3) and Gamma(2/3). This is provided by functions in the file
   25400 	gammaonethird.c
   25401 
   25402 	* There is no test file for mpfr_ai2 since it should quickly disappear behind
   25403 	a single implementation using the best of mpfr_ai and mpfr_ai2.
   25404 	However, if necessary, a test file can be obtained by copying tai.c and
   25405 	replacing mpfr_ai by mpfr_ai2 everywhere.
   25406 
   25407 	* I do not know if gammaonethird.c will remain like that in the future. Should
   25408 	we make this implementation available as a public MPFR function? In this case,
   25409 	I have to write a wrapper for providing a correctly rounded implementation.
   25410 	Moreover, it contains functions that could be interesting for the
   25411 	implementation of other functions (the functions mpfr_div_ui*). Maybe, it
   25412 	could be worth providing a file specially for this purpose.

   25449 
   25450 2010-05-08  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   25451 
   25452 	[tests/tests.c] fixed compiler warning (found by nightly tests)
   25453 
   25454 2010-05-07  Vincent Lefvre  <vincent (a] vinc17.net>
   25455 
   25456 	New exponent type mpfr_exp_t for MPFR (replacing GMP's mp_exp_t).
   25457 
   25458 	[README.dev] Updated a paragraph concerning signed and unsigned types.
   25459 
   25460 	Changed the precision type mpfr_prec_t from an unsigned integer type
   25461 	into the corresponding signed integer type, in order to avoid problems
   25462 	due to the usual arithmetic conversions when mixing mpfr_prec_t and
   25463 	mp_exp_t in an expression.
   25464 	* NEWS: mentioned this change.
   25465 	* mpfr-impl.h: removed MPFR_INTPREC_MAX (which wasn't used) and updated
   25466 	  the MPFR_UNSIGNED_MINUS_MODULO(S,A) macro, which assumed that A was
   25467 	  unsigned; this macro now works even when A is signed.
   25468 	* mpfr.h: added mpfr_uprec_t; updated mpfr_prec_t and MPFR_PREC_MAX.
   25469 	* tests/tcheck.c: disabled a test on MPFR_PREC_MAX+1 with MPFR >= 3
   25470 	  (this test doesn't work with a signed mpfr_prec_t and isn't needed).
   25471 	Note: all tests pass under GNU Linux x86 and x86_64.
   25472 
   25473 	[tests/tcheck.c] Forgot to remove a printf (added during testing).
   25474 
   25475 	[tests/tcheck.c] Support signed mpfr_prec_t (avoid integer overflow).
   25476 
   25477 	[tests/mpf_compat.h] Fixed prototype of function main.
   25478 
   25479 	[mpfr.h] Added a comment concerning the definition of MPFR_PREC_MAX.
   25480 
   25481 2010-05-06  Vincent Lefvre  <vincent (a] vinc17.net>
   25482 
   25483 	print_rnd_mode.c: added an assertion so that we do not forget to update
   25484 	this file after a new rounding mode is added.
   25485 
   25486 2010-05-03  Vincent Lefvre  <vincent (a] vinc17.net>
   25487 
   25488 	[mpfr.texi] Added a paragraph about multiple inclusions of mpfr.h and/or
   25489 	gmp.h header files.
   25490 
   25491 2010-05-03  Philippe Thveny  <philippe.theveny (a] laposte.net>
   25492 
   25493 	Update documentation for mpfr_print_rnd_mode.
   25494 
   25495 2010-05-03  Vincent Lefvre  <vincent (a] vinc17.net>
   25496 
   25497 	To avoid breaking the ABI when faithful rounding gets implemented, added
   25498 	MPFR_RNDF to the mpfr_rnd_t enum type now, and removed MPFR_RND_MAX from
   25499 	the enumeration (it is now defined as a macro in mpfr-impl.h).
   25500 
   25501 	fits_* (signed version): corrections and optimizations.
   25502 
   25503 	[fits_uintmax.c, fits_u.h] Some casts could be incorrect in the case
   25504 	mp_exp_t > mpfr_prec_t. Set prec to the int type since in practice,
   25505 	prec will be small enough to fit in an int. The fact that prec is now
   25506 	signed allows us to remove a useless test (also note that prec should
   25507 	be computed at compile time, so that this should be at least as fast).
   25508 
   25509 	[fits_uintmax.c, fits_u.h] Comments: doesn't -> don't
   25510 
   25511 	mpfr.texi: updated the month.
   25512 
   25513 2010-05-03  Philippe Thveny  <philippe.theveny (a] laposte.net>

   25522 
   25523 	[fits_intmax.c,fits_s.h] Added FIXME comments.
   25524 
   25525 	Optimized fits_u.h and made fits_uintmax.c like fits_u.h for the
   25526 	special numbers.
   25527 
   25528 	Optimized mpfr_fits_uintmax_p.
   25529

   25545 
   25546 	[mpfr-gmp.h] Fixed alloca prototype (bug detected by tcc 0.9.25
   25547 	under Linux/x86_64).
   25548 
   25549 2010-03-24  Vincent Lefvre  <vincent (a] vinc17.net>
   25550 
   25551 	[mpfr.texi] Improved/corrected the documentation of functions

   25554 
   25555 	[mpfr.texi] Removed a "currently" that is no longer needed.
   25556 
   25557 	[mpfr.texi] Updated description of mpfr_atan2, now that IEEE 754-2008
   25558 	has been published and follows the same conventions as C99 for atan2.
   25559 
   25560 	[mpfr.texi] Updated description of mpfr_pow, now that IEEE 754-2008
   25561 	has been published and follows the same conventions as C99 for pow.
   25562 	(IEEE 754-2008 doesn't currently specify pow(inf,non-zero), but
   25563 	I've suggested a correction for the errata page.)

   25591 2010-03-19  Sylvain Chevillard  <Sylvain.Chevillard (a] inria.fr>
   25592 
   25593 	Added a mention about the current limitation of mpfr_ai in mpfr.texi.
   25594 
   25595 	Removed check of ai.c for large arguments. I added in algorithms.tex a

   25644 
   25645 	* Added function mpfr_ai. The implementation is the most naive: it evaluates
   25646 	  the series step by step until it can stop.
   25647 	  A special strategy is used to detect possible problems when Ai(x) is very
   25648 	  close to 0.
   25649 
   25650 	* Updated algorithms.tex with the technical description of the implementation
   25651 	  of mpfr_ai.
   25652 
   25653 	* Added algorithm2e.sty and algorithm2e-compatibility.sty (necessary to
   25654 	  compile algorithms.tex now).
   25655 
   25656 	* Updated mpfr.texi to let it know this new function.
   25657 
   25658 	* Added a basic test file for mpfr_ai. I will add other test cases later.
   25659 
   25660 	* Added a small HOWTO to README.dev about how to add a new test file for new

   25726 2010-02-18  Vincent Lefvre  <vincent (a] vinc17.net>
   25727 
   25728 	* Added tests/tstdint.c to test the double inclusion of mpfr.h when only
   25729 	  the second occurrence needs <stdint.h> (this can happen when one uses
   25730 	  several libraries that use MPFR under different conditions).
   25731 	* Added tstdint to the svn:ignore property of "tests".
   25732 	* TODO: mentions that tstdint should be added to check_PROGRAMS in
   25733 	  the tests/Makefile.am file once this is fixed.
   25734

   25740 
   25741 	mpfr.h: disable the INTMAX_C / UINTMAX_C test with C++ compilers as it
   25742 	doesn't work well in this case (e.g. possible failure with Boost); see
   25743 	  https://sympa.inria.fr/sympa/arc/mpfr/2010-02/msg00025.html

   25760 2010-01-25  Vincent Lefvre  <vincent (a] vinc17.net>
   25761 
   25762 	Simplified get_patches.sh; minor consequence: the trailing space in
   25763 	the string returned by mpfr_get_patches() when there are patches is
   25764 	no longer present (this trailing space wasn't desired anyway).
   25765 
   25766 	configure.in: updated message for different gmp.h and libgmp versions.

   25770 
   25771 	FAQ.html, faq.xsl, README, TODO: slightly changed the copyright notice
   25772 	to make it consistent with the one of the other files. In short, "and
   25773 	the GNU General Public License" has been removed, but it was ambiguous
   25774 	(we did not say which version of the GNU GPL) and useless (for GPLv3)
   25775 	because the LGPLv3 is compatible with the GPLv3:
   25776 	  https://www.gnu.org/licenses/gpl-faq.html#WhatDoesCompatMean
   25777 
   25778 	INSTALL:
   25779 	  * added copyright notice (at the top, like GMP);

   25781 
   25782 	Copyright notice update: added 2010 with
   25783 	  perl -pi -e 's/2009 Free Software/2009, 2010 Free Software/' **/*(^/)
   25784 	under zsh, reverting the ChangeLog file and the mbench directory.
   25785 
   25786 	tests: added turandom to the svn:ignore property.
   25787 
   25788 	INSTALL: updated paragraphs about the search paths (in particular,
   25789 	--with-gmp=/usr/local is no longer chosen as an example as it does
   25790 	not work as expected; a note has been added about that).
   25791 
   25792 	INSTALL: rewrote a paragraph about search paths.

   25805 
   25806 	tests/turandom.c: updated a test (if emin > 1 and rnd == MPFR_RNDN,

   25890 
   25891 	configure.in: replaced BITS_PER_MP_LIMB by GMP_NUMB_BITS (should have

   25893 
   25894 	mpfrlint: check that GMP_LIMB_BITS isn't used.
   25895 
   25896 	Replaced GMP_LIMB_BITS by GMP_NUMB_BITS to use only one of these macros.

   25898 2010-01-08  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   25900 	[configure.in] put back test BITS_PER_MP_LIMB == BYTES_PER_MP_LIMB * CHAR_BIT

   25904 	BITS_PER_MP_LIMB -> GMP_LIMB_BITS
   25905 	got rid of BYTES_PER_MP_LIMB in configure.in (no longer defined by GMP)

   25923 
   25924 	[scale2.c] added missing include (compilation with --with-gmp-build did fail)
   25925 	[exp_2.c] small improvements in Smith method: compute x^{2i} as (x^i)^2 instead
   25926 		  of x^{i-1} * x. The error analysis is unchanged.
   25927 	[tuneup.c] fix for sin_cos threshold (we had a problem since mpfr_sin_cos
   25928 		   was calling mpfr_cos, which was calling mpfr_sincos_fast in some
   25929 		   cases

   25938 
   25939 	patch to recognize IEEE quad, little endian format for "long double"
   25940 
   25941 	[scale2.c] now mpfr_scale2 is included in mpfr-impl.h, instead of #including

   25944 2009-12-07  Vincent Lefvre  <vincent (a] vinc17.net>
   25945 
   25946 	sin_cos.c: in case of tiny inputs, keep the flags. In practice, this
   25947 	fixes the following bug in mpfr_sin_cos (shown by the latest additions
   25948 	to tsin_cos.c): if emin is the minimal exponent (MPFR_EMIN_MIN), the
   25949 	absolute value of the input is the minimum positive number and the
   25950 	rounding mode is toward 0 (or equivalent), then the underflow flag is
   25951 	dropped. The other exception cases (e.g., in case of reduced exponent
   25952 	range) are handled by mpfr_check_range().
   25953 
   25954 	tests/tsin_cos.c: in consistency(), better error message.
   25955 
   25956 	tests/tsin_cos.c: in consistency(), improved testing on underflow case.
   25957 
   25958 	tests/tsin_cos.c: in consistency(), added testing on underflow case.

   25960 	tests/tsin_cos.c: in consistency(), fixed flags testing.
   25961 
   25962 	tests/tsin_cos.c: in consistency(), test also the flags.
   25963 
   25964 	tests/tsin_cos.c: in consistency(), test also the returned value
   25965 	(the one that gives inexact-related information).

   26068 
   26069 	sin_cos.c: fixed a potential bug by changing a rnd_mode into MPFR_RNDZ
   26070 	in mpfr_can_round. Indeed, in r4574, the change from
   26071 	  if (!mpfr_can_round (c, m, GMP_RNDZ, rnd_mode, MPFR_PREC (z)))
   26072 	to
   26073 	  if (!mpfr_can_round (c, m, GMP_RNDN, rnd_mode,
   26074 	                       MPFR_PREC (z) + (rnd_mode == GMP_RNDN)))
   26075 	looks wrong to me: in RNDN, the extra bit due to rnd_mode == GMP_RNDN
   26076 	changes a RNDN worst case into a RNDZ worst case.
   26077 	Note: The second mpfr_can_round with the same problem has been fixed
   26078 	in r6513.
   26079

   26243 
   26244 	[frac.c] Patch r6456 was incorrect: the problem with the non-significant

   26287 	do that only for the general case.
   26288 
   26289 	tests/tmodf.c: added overflow tests.

   27170 	the 3rd argument of mpz_divexact_ui is an unsigned long, not a limb.
   27171 	So, fixed the shift count (assuming no padding bits in unsigned long).
   27172 
   27173 	zeta_ui.c bug fix: a shift count could be >= width of type (if a limb is
   27174 	a long long and long long is twice the size of a long). This problem was
   27175 	detected by a warning on gcc40 with CFLAGS="-mpowerpc64 -mcpu=970 -O2".

   27370 2009-02-23  Vincent Lefvre  <vincent (a] vinc17.net>
   27371 
   27372 	Changed how the test of MPFR_VERSION_MAJOR, MPFR_VERSION_MINOR and
   27373 	MPFR_VERSION_PATCHLEVEL vs MPFR_VERSION_STRING is performed.
   27374 	Detailed explanations:
   27375 	  The test was enabled only in release tarballs (suffix not present),
   27376 	  where tests/tversion.c normally contained a "#if 1" (though this
   27377 	  is not the case in the MPFR 2.4.0 tarball). In patches, this test
   27378 	  should be disabled by changing the "#if 1" into "#if 0", due to
   27379 	  the suffix. But as one should be able to apply any patches (in any
   27380 	  order), this method was not satisfactory. The test has been moved
   27381 	  from tests/tversion.c to tests/tests.c (in function test_version),
   27382 	  and the suffix is now ignored in this test; the change of #if has
   27383 	  been removed from the update-version script.

   27549 2009-01-20  Vincent Lefvre  <vincent (a] vinc17.net>
   27550 
   27551 	Fixed bug reported by Chris Saunders: if _GMP_IEEE_FLOATS is defined,
   27552 	the build of tset_ld.c fails because DOUBLE_ISNAN expects a lvalue.
   27553 	* mpfr-impl.h: documented that for such macros, the argument must
   27554 	  be a lvalue, and always make sure that it is a lvalue (so that
   27555 	  a failure doesn't depend on the environment).
   27556 	* tests/tset_ld.c: fixed the bug.

   27575 	tests/tset_d.c: fixed test of mpfr_set_d on -0 with gcc -ffast-math
   27576 	(the -d for d = 0.0 was giving 0.0, hence a spurious failure).
   27577 
   27578 	mpfr-impl.h: the DOUBLE_ISNAN macro wasn't working with gcc -ffast-math
   27579 	(at least on x86_64); fixed that by adding another test.
   27580 	tests/tset_ld.c: Isnan_ld wasn't working either; also the NaN test was
   27581 	incorrect. Now, the failure on NaN is correctly reported.
   27582 
   27583 	tests/tcmp_d.c, tests/tcmp_ld.c, tests/tset_d.c: corrected message.

   27587 	Note: in tset_d.c, moved the NaN test before the signed-zero test
   27588 	to catch the failure on the NaN first.
   27589

   27612 	  * Add void in prototypes of functions taking no arguments.

   28087 
   28088 	Updated NEWS file.
   28089 
   28090 	strtofr.c: in r5660, as pstr_size and pstr->prec both have type size_t,

   28092 
   28093 	strtofr.c: reverted the change done in r3008, which led to a trivial

   28095 	size_t) can be represented in a mp_exp_t (as required in the code).

   28173 	[tget_str.c] replaced 'double' input by 'char*' to avoid problems with single
   28174 	             precision (partially solves #3353)
   28175 
   28176 2008-09-17  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   28177 
   28178 	[README.dev] added item about coverage of releases
   28179 
   28180 2008-09-16  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   28181

   28185 
   28186 2008-09-16  Vincent Lefvre  <vincent (a] vinc17.net>
   28187 
   28188 	NEWS, mpfr.texi: documented the fact that mpfr_random and mpfr_random2
   28189 	will be suppressed in the next release.
   28190 
   28191 	ChangeLog update with "LC_ALL=en_US.UTF8 TZ=UTC svn log -rHEAD:0 -v".
   28192 
   28193 2008-09-10  Philippe Thveny  <philippe.theveny (a] laposte.net>
   28194 
   28195 	tests/tpow_z.c: Check test for bug20080904 with the minimum possible negative exponent so as not to underflow with (future) 128 bits machine.
   28196 
   28197 2008-09-06  Vincent Lefvre  <vincent (a] vinc17.net>
   28198 
   28199 	pow.c: fixed bug20080904 (from tpow_z.c).
   28200 
   28201 	pow.c: added log messages.
   28202 
   28203 2008-09-05  Philippe Thveny  <philippe.theveny (a] laposte.net>
   28204 
   28205 	tests/tpow_z.c: Add a test that underflows.
   28206 
   28207 2008-09-05  Vincent Lefvre  <vincent (a] vinc17.net>
   28208 
   28209 	configure.in: updated a comment (for the next automake version).
   28210 
   28211 	NEWS: added a note about mpfr_init_gmp_rand (removed in r4953).
   28212 
   28213 2008-09-04  Vincent Lefvre  <vincent (a] vinc17.net>
   28214 
   28215 	README.dev: update (about AM_MAINTAINER_MODE).
   28216 
   28217 2008-09-02  Vincent Lefvre  <vincent (a] vinc17.net>
   28218 
   28219 	Updated README file.
   28220 
   28221 2008-09-01  Vincent Lefvre  <vincent (a] vinc17.net>
   28222 
   28223 	Removed patch-libtool and updated README.dev as libtool has been fixed.
   28224 
   28225 	NEWS file update (get default $CC and $CFLAGS from gmp.h).
   28226 
   28227 	configure.in: removed a useless blank line.
   28228 
   28229 	README.dev: reverse-merged r5440 (about __GMP_CC/__GMP_CFLAGS) as said.
   28230 
   28231 2008-08-27  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   28232 
   28233 	[algorithms.tex] the truncation error for rec_sqrt was correct, but the
   28234 	reasoning was not detailed enough
   28235 
   28236 2008-08-27  Vincent Lefvre  <vincent (a] vinc17.net>
   28237 
   28238 	Added patch-aclocal-icc; this is a port of the patch posted on
   28239 	  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=485421
   28240 	for aclocal.m4 when libtool 1.5.26-4 from Debian has been used.
   28241 
   28242 2008-08-27  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   28243 
   28244 	[rec_sqrt.c] fixed bug "bad_case1" (truncation error was forgotten, when
   28245 	output precision was smaller than input precision)
   28246 
   28247 2008-08-27  Vincent Lefvre  <vincent (a] vinc17.net>
   28248 
   28249 	mpfr.texi: updated the month.
   28250 
   28251 2008-08-26  Vincent Lefvre  <vincent (a] vinc17.net>
   28252 
   28253 	tests/trec_sqrt.c: enable the tests only with MPFR 2.4.0+.
   28254 
   28255 	NEWS: noted when some changes were applied in 2.3.* versions.
   28256 
   28257 2008-08-25  Vincent Lefvre  <vincent (a] vinc17.net>
   28258 
   28259 	README.dev: completed information about integer types.
   28260 
   28261 	README.dev: added information about mixing signed and unsigned types.
   28262 
   28263 	li2.c: avoid even more mixing between signed and unsigned types, by
   28264 	casting mpfr_prec_t to mp_exp_t in expressions involving mp_exp_t.
   28265 	This time the bug is fixed: tli2 no longer freezes in 64 bits.
   28266 
   28267 	li2.c: use an "int" instead of "unsigned int" in li2_series() to avoid
   28268 	mixing signed and unsigned types, which can yield implicit conversions
   28269 	from signed into unsigned, and maybe problems on some platforms. This
   28270 	doesn't fix the current freeze of tli2 on 64-bit machines, though.
   28271 
   28272 2008-08-24  Vincent Lefvre  <vincent (a] vinc17.net>
   28273 
   28274 	tests/tgeneric.c: changed the way a warning with gcc 4.2+ is avoided
   28275 	(r5335), as suggested by Manuel Lpez-Ibez on GCC bug 36299.
   28276 
   28277 2008-08-21  Vincent Lefvre  <vincent (a] vinc17.net>
   28278 
   28279 	Added data_check support to mpfr_sqr.
   28280 	Added bad_cases support to mpfr_sqr and mpfr_sqrt.
   28281 
   28282 	tests/tsqr.c: corrected function definitions.
   28283 
   28284 	Added data_check & bad_cases support to mpfr_rec_sqrt.
   28285 
   28286 	tests/trec_sqrt.c: added bad case that makes mpfr_rec_sqrt fail.
   28287 
   28288 	mpfr-impl.h: as not all ICC versions define the __ICC macro (only
   28289 	the __INTEL_COMPILER macro can be defined), define the __MPFR_ICC
   28290 	and __MPFR_GNUC macros in another way.
   28291 
   28292 	tests/tsprintf.c: fixed compilation failure when HAVE_DENORMS isn't
   28293 	defined, such as with icc 10.1 on Itanium.
   28294 
   28295 	tests/tprintf.c: to allow random values to be reproducible,
   28296 	do not call randlimb several times in a same expression,
   28297 	because the evaluation order is unspecified.
   28298 
   28299 	tests/tpow_all.c: added test of mpfr_rec_sqrt (only with MPFR 2.4.0+).
   28300 
   28301 	tests/tpow_all.c: removed useless parentheses.
   28302 
   28303 	rec_sqrt.c: added logging support.
   28304 
   28305 	algorithms.tex: replaced "towards" by "toward" for consistency with
   28306 	the MPFR manual and the standards.
   28307 
   28308 	algorithms.tex: corrected English usage, spelling and typography
   28309 	in the section on mpfr_hypot.
   28310 
   28311 2008-08-20  Vincent Lefvre  <vincent (a] vinc17.net>
   28312 
   28313 	tests/thypot.c: added a test for tiny x and y (already done by the
   28314 	generic tests, but not yet in the 2.3 branch in extended exponent
   28315 	range).
   28316 
   28317 	tests/tgeneric.c: for the special cases tested in precision p1
   28318 	for n <= 3, set the extended exponent range.
   28319 
   28320 	tests/thypot.c: improved error messages.
   28321 
   28322 	tests/thypot.c: perform some tests both in the current exponent range
   28323 	and in the extended exponent range, so that the lost-overflow bug of
   28324 	MPFR 2.3.1 can be triggered on 64-bit machines too.
   28325 
   28326 	tests/tpow_all.c:
   28327 	  * In cmpres(), if z1 and z2 were both zeros, their sign wasn't tested.
   28328 	  * Added test of mpfr_sqr and mpfr_sqrt.
   28329 
   28330 	mpfr.texi: added a paragraph on MPFR internal data.
   28331 
   28332 	pow_si.c: fixed the underflow/overflow detection for n < 0 by using
   28333 	a method similar to mpfr_pow_z.
   28334 
   28335 	pow_si.c: added logging support.
   28336 
   28337 	pow.c: fixed bug in mpfr_pow_general by computing correct bounds
   28338 	on exp(y*ln|x|). ==> tpow no longer fails in bug20080820.
   28339 	Note: this bug could affect only underflow cases and possibly cases
   28340 	near overflow.
   28341 
   28342 	tests/tpow.c: updated comment for bug20080820().
   28343 
   28344 	tests/tpow.c: added testcase for bug mentioned in r5552.
   28345 
   28346 	pow_z.c: solves the underflow problem in round-to-nearest by using
   28347 	mpfr_pow_general in precision 2 (like in mpfr_pow_pos_z), but this
   28348 	currently fails due to a more general bug from r4940 (the rounding
   28349 	modes to compute an upper bound on exp(y*ln|x|) are incorrect).
   28350 
   28351 	pow_z.c: formatting.
   28352 
   28353 	pow_z.c: moved a log message.
   28354 
   28355 	pow_z.c: added log messages.
   28356 
   28357 	tests/tpow_all.c: added an underflow test of x^y with y integer < 0.
   28358 
   28359 	pow_z.c: no longer take care of the possibly lost overflow flag, as
   28360 	the other functions do not do this either; this general problem has
   28361 	been fixed in mpfr_check_range (r5545).
   28362 
   28363 	Fixed the following problem:
   28364 	  The overflow flag can be lost in many functions called with the
   28365 	  maximum exponent equal to MPFR_EMAX_MAX (this is the default on
   28366 	  32-bit machines) when the temporary result (in a higher precision)
   28367 	  is representable but once rounded, it yields an overflow.
   28368 	This needed a slight change of behavior of the mpfr_check_range function
   28369 	(defined in exceptions.c). Described this change in mpfr.texi and NEWS.
   28370 
   28371 	pow_z.c: fixed some of the underflow/overflow problems for z < 0.
   28372 
   28373 	tests/tpow_all.c: fixed mpfr_clear in overflow_inv.
   28374 
   28375 	tests/tpow_all.c: more detailed error messages.
   28376 
   28377 	tests/tpow_all.c: improved overflow_inv tests to trigger a bug
   28378 	in mpfr_pow_z due to incorrect rounding mode settings in r5315:
   28379 	on a 64-bit Linux machine, "./tpow_all 1" ends with:
   28380 	Bad overflow flag in overflow_inv for mpfr_pow, extended exponent range,
   28381 	s = 1, t = 1, GMP_RNDZ
   28382 
   28383 	tests/tpow_all.c: in overflow_inv, reduced t to [0,5] and added tests.
   28384 
   28385 2008-08-19  Vincent Lefvre  <vincent (a] vinc17.net>
   28386 
   28387 	tests/tpow_all.c: improved error messages.
   28388 
   28389 	tests/tpow_all.c: changed the precisions in overflow_inv for clearer
   28390 	output (the reported failures are the same).
   28391 
   28392 	tests/tpow_all.c: information about extended exponent range wasn't
   28393 	always output. For simplicity to provide such an information, made
   28394 	ext a global variable.
   28395 
   28396 	tests/tpow_all.c: added overflow tests for x^(-1). -> Failure.
   28397 
   28398 	Fixed basic underflow checking in mpfr_pow.
   28399 
   28400 2008-08-18  Vincent Lefvre  <vincent (a] vinc17.net>
   28401 
   28402 	mpfr-impl.h: defined macro INITIALIZED to declare that some variable
   28403 	  is initialized before being used.
   28404 	README.dev: described the use of this macro.
   28405 	lngamma.c: replaced the dummy initialization by this macro.
   28406 
   28407 2008-08-16  Vincent Lefvre  <vincent (a] vinc17.net>
   28408 
   28409 	pow.c: updated comments.
   28410 
   28411 	tests/tpow_all.c: added tests -> assertion failed in pow.c line 603.
   28412 
   28413 2008-08-15  Vincent Lefvre  <vincent (a] vinc17.net>
   28414 
   28415 	tests/tpow_all.c: added test of mpfr_ui_div.
   28416 
   28417 	pow_z.c: improved comments.
   28418 
   28419 2008-08-14  Vincent Lefvre  <vincent (a] vinc17.net>
   28420 
   28421 	mpfr.texi: additions related to MPFR caches.
   28422 	  * Added Section "Memory Handling" mentioning caches.
   28423 	  * Added call to mpfr_free_cache in the first example.
   28424 	  * Updated description of function mpfr_free_cache.
   28425 
   28426 	tests/texp.c: improved an underflow test to trigger the bug fixed
   28427 	in r5453 on 32-bit machines too.
   28428 
   28429 	log.c: fixed a log message.
   28430 
   28431 	exp_2.c: fixed other log messages.
   28432 
   28433 	exp_2.c: fixed a log message (the format didn't correspond to the types)
   28434 	and improved it.
   28435 
   28436 2008-08-12  Vincent Lefvre  <vincent (a] vinc17.net>
   28437 
   28438 	tests/tdiv.c: completed underflow test by testing negative results too.
   28439 
   28440 	mul_2si.c, div_2si.c, div_2ui.c: fixed double-rounding problem in
   28441 	rounding to nearest when the rounded result in unbounded exponent
   28442 	range is 2^(emin - 2).
   28443 	tests/tmul_2exp.c: test x = 15/16 too. Now tmul_2exp no longer fails
   28444 	(with the correction in div.c from r5515).
   28445 
   28446 	tests/tdiv.c correction: the underflow bug was in case when the
   28447 	result had to be zero.
   28448 
   28449 	div.c: fixed underflow bug that occurs in rounding to nearest when
   28450 	the rounded result in unbounded exponent range is 2^(emin - 2) and
   28451 	inex > 0: one got a non-zero result instead of +/-0.
   28452 
   28453 	tests/tdiv.c: added a test that triggers a bug in mpfr_div in case of
   28454 	underflow in rounding to nearest when the result must be non-zero.
   28455 
   28456 	div.c: added logging support.
   28457 
   28458 	tests/tmul_2exp.c: test mpfr_div_2ui too.
   28459 
   28460 	tests/tmul_2exp.c: test mpfr_div_2si too.
   28461 
   28462 	tests/tmul_2exp.c: updated underflow() test to trigger a double-rounding
   28463 	bug in case of underflow.
   28464 
   28465 	tests/texp.c: updated comment (the double-rounding bug triggered by
   28466 	underflow_up() is in mpfr_mul_2si).
   28467 
   28468 	tests/texp.c: updated underflow_up() test: added case exp(eps) ~= 1/2,
   28469 	which fails due to a double-rounding problem in rescaling the result.
   28470 
   28471 	tests/texp.c: improved comments in underflow_up().
   28472 
   28473 2008-08-11  Vincent Lefvre  <vincent (a] vinc17.net>
   28474 
   28475 	Merged vlefevre branch:
   28476 	    svn merge -c-5445 .
   28477 	    svn merge -r5436:HEAD .../mpfr/branches/vlefevre
   28478 	* pow.c:
   28479 	  - Moved the general case from mpfr_pow() to a new internal function
   28480 	    mpfr_pow_general().
   28481 	  - In this function (from old code), avoid unnecessary overflow test
   28482 	    if the intermediate result is not an infinity (which was the case
   28483 	    of underflow with non-zero result, thus not an overflow).
   28484 	  - Fixed a double-rounding problem that occurred in this function in
   28485 	    some underflow cases when rescaling the result.
   28486 	  - Added log messages.
   28487 	* mpfr-impl.h: added mpfr_pow_general prototype.
   28488 	* pow_z.c:
   28489 	  - The underflow case of mpfr_pow_pos_z() in rounding to nearest,
   28490 	    which was incorrect, is now handled by calling mpfr_pow_general(),
   28491 	    which can scale the result thus decide whether the rounded result
   28492 	    should be 0 or nextabove(0). To avoid the exact cases of x^y with
   28493 	    y integer (not supported by mpfr_pow_general()), rounding is done
   28494 	    in precision 2 (this is also faster!).
   28495 	  - Fixed underflow-related bug (case exact result = 2^(emin-2), in
   28496 	    rounding to nearest).
   28497 	  - Added log messages.
   28498 	* pow_ui.c:
   28499 	  - Swapped parameters x and y for consistency (-> y = x^n).
   28500 	  - Fixed the internal overflows and underflows (which could yield
   28501 	    spurious overflows/underflows and incorrect results) by using
   28502 	    mpfr_pow_z.
   28503 	* tests/tpow_all.c:
   28504 	  - Test flags in test_others and cmpres; cmpres argument z1 can now
   28505 	    be a null pointer (if unknown pure FP value, thus not tested).
   28506 	  - Added a test of 2^(emin - i/4) with 0 <= i <= 12, that triggered
   28507 	    the bugs mentioned above (and now fixed).
   28508 
   28509 	[Added during the Subversion to Git conversion]
   28510 	A merge commit could not be generated for Git.
   28511 	Branch in Git: refs/deleted/r5506/heads/vlefevre
   28512 
   28513 2008-08-11  Vincent Lefvre  <vincent (a] vinc17.net>
   28514 
   28515 	tests/tmul_2exp.c: added underflow tests.
   28516 
   28517 	Added logging support to mpfr_{mul,div}_2{si,ui}.
   28518 
   28519 2008-08-08  Vincent Lefvre  <vincent (a] vinc17.net>
   28520 
   28521 	mpfr-impl.h: added a space for MPFR_LOG_MSG.
   28522 
   28523 	README.dev: corrected MPFR_LOG_MSG example.
   28524 
   28525 	mpfr.h: added a comment concerning ICC.
   28526 
   28527 2008-08-07  Vincent Lefvre  <vincent (a] vinc17.net>
   28528 
   28529 	Final code clean-up based on icc warnings.
   28530 
   28531 	Further code clean-up (and consistency) based on icc warnings:
   28532 	  * Removed useless code.
   28533 	  * Avoid hiding variable declarations.
   28534 	  * Use #ifdef BOOL_MACRO instead of #if BOOL_MACRO.
   28535 	  * In MPFR_RNDRAW_GEN macro definition, variables declared locally now
   28536 	    start with an underscore to avoid possible conflits with parameters
   28537 	    (and modified macro calls that use these variables).
   28538 
   28539 	round_prec.c: avoid hiding variable declaration (detected by icc).
   28540 
   28541 	pow_si.c: fixed Ziv's iteration (code from r3305) by using MPFR_ZIV_NEXT
   28542 	(problem detected by icc, because variable "loop" was never used).
   28543 
   28544 	mul_ui.c: removed variable that was set but never used (detected by icc,
   28545 	but not by gcc, probably because of early optimization).
   28546 
   28547 	inp_str.c: fixed possible implementation-defined behavior (a value
   28548 	from the unsigned char range -- from getc -- was stored in a char,
   28549 	and if the char type is signed and the value cannot be represented
   28550 	in a char, this is implementation-defined).
   28551 
   28552 	get_str.c: avoid hiding variable declaration (detected by icc).
   28553 
   28554 	div.c: avoid hiding variable declaration (detected by icc).
   28555 
   28556 	mpfr.h, mpfr-impl.h: avoid warnings with icc (at least icc 10.1).
   28557 	README.dev: added a paragraph on the test of "boolean" macros.

   28581 
   28582 	Added algorithms.out to svn:ignore property.
   28583 
   28584 	tests/texp.c: added testcase for new bug found in mpfr_exp_2.
   28585 
   28586 	exp.c, exp_2.c: fixed the overflow/underflow detection. The underflow_up
   28587 	test in texp.c still fails for mpfr_exp_2 only, but this seems to be due
   28588 	to a bug in this function (incorrect error bound?).
   28589 
   28590 	tests/texp.c: added underflow tests to underflow_up; currently fail due
   28591 	to incorrect underflow detection in mpfr_exp (and if this detection is
   28592 	disabled, mpfr_exp_3 behaves correctly, but not mpfr_exp_2).

   28605 
   28606 	exp3.c: fixed internal underflow.
   28607 
   28608 	fma.c, fms.c: added a comment about apparently incorrect scaling.

   28625 
   28626 	tests/texp.c: completed a comment.
   28627 
   28628 	tests/texp.c: updated underflow_up test of log(2^(emin - 1)) + eps:
   28629 	  * In the old test (- log(2) < eps < 0 in GMP_RNDN), do not test
   28630 	    the flags, as this may be incorrect on some platforms (though
   28631 	    unlikely). Better tests will be provided later.
   28632 	  * Added test for case eps > 0, which triggers a bug in mpfr_exp_3
   28633 	    (underflow flag sometimes set while it shouldn't be set).
   28634 
   28635 	exp.c: completed a comment, describing how rigorous underflow/overflow
   28636 	detection can be done.

   28656 	tests/texp.c: updated comment of underflow_up.
   28657 
   28658 	exp_2.c: solved the assertion failure by detecting a zero due to a
   28659 	cancellation and increasing the precision via Ziv's loop in such a
   28660 	case.
   28661 
   28662 	exp_2.c: added another assertion, that is checked independently of
   28663 	the value of MPFR_EXP_2_THRESHOLD (better for debugging).
   28664 
   28665 	exp_2.c: added an assertion (more explicit than a similar assertion
   28666 	that would fail later) in mpfr_exp2_aux, caught by the underflow_up
   28667 	test in texp.c for prec = 16 on a 64-bit Linux machine.

   28674 	tests/tpow_all.c: added test of mpfr_exp2 and mpfr_exp10.
   28675

   28716 	tests/tpow_z.c: fixed NaN^0 test.
   28717 
   28718 	Fixed a bug in pow_ui.c and pow_z.c: NaN^0 returned NaN instead of 1
   28719 	(see documentation). Affected functions: mpfr_pow_ui, mpfr_pow_si and
   28720 	mpfr_pow_z (but not mpfr_pow). Added new test file tests/tpow_all.c

   28826 	Clean-up and various changes to be able to build MPFR with g++.
   28827 	But the following 3 tests currently fail with g++ 4.3.1:
   28828 	  FAIL: tprintf
   28829 	  FAIL: tsprintf
   28830 	  FAIL: tfprintf
   28831 	This is an "Illegal instruction" error, so probably a bug in g++.
   28832 	[Edit: acinclude.m4 now uses gl_SIZE_MAX, typically from size_max.m4,

   28835 
   28836 	vasprintf.c: do not use pointer arithmetic on void *.
   28837 
   28838 	configure.in: added -Wpointer-arith to gcc options (this warning
   28839 	is useful as pointer arithmetic on void * is a gcc extension and
   28840 	doesn't work with g++).
   28841 
   28842 	README.dev: mentioned a libtool bug with recent versions of icc.
   28843

   28855 
   28856 	fixed typo, added argument reduction for atan (we should try it since I believe
   28857 	atan is slow wrt exp, log, sin, cos for large precisions)
   28858 
   28859 	simplified error analysis of log1p (did not match the code), and improved the

   28869 	doesn't work from MPFR's directory.
   28870 
   28871 	mpfr.texi: added Section 4.1 "Headers and Libraries" partly based on
   28872 	GMP's. Note: in the generated mpfr.info file, the cross reference to
   28873 	libtool does not work (though GMP's info manual has exactly the same
   28874 	one and it works there). I couldn't figure out why.
   28875 
   28876 	mpfr.texi: make cross reference in HTML similar to texinfo's default one

   28888 	(this should have been done in r4059).
   28889 
   28890 	mpfrlint: check GFDL versions.
   28891 
   28892 	mpfr.texi, update-version: in the MPFR manual, replaced two

   28894 	which can be updated by update-version.
   28895 
   28896 	mpfr.texi: completed paragraph on MPFR vs double-precision numbers.
   28897 
   28898 	mpfr.texi: replaced each @code{mpfr} by MPFR (for consistency).

   28903 
   28904 2008-05-23  Vincent Lefvre  <vincent (a] vinc17.net>
   28905 
   28906 	tests: added tprintf to svn:ignore property.
   28907 
   28908 	Added documentation about "'var' may be used uninitialized in this
   28909 	function" warnings.
   28910 
   28911 2008-05-22  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   28912 
   28913 	Added comments about int i = i trick to avoid warning about uninitialized
   28914 	variables. This has the advantage to generate no code, but works for gcc only.
   28915 
   28916 2008-05-21  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   28917 
   28918 	initialize bbcp and bbcp1 to -1 (should be invalid)
   28919 	added MPFR_ASSERTN to check they are not -1 before reads
   28920 	simplified a test: (rnd == RNDN) || (rnd != RNDZ) ==> rnd != RNDZ
   28921 
   28922 	got rid of false (?) compiler warnings for uninitialized values
   28923 	-> we might want to revert this change if we find a better solution and/or
   28924 	   if the problem is fixed in gcc
   28925 
   28926 2008-05-20  Vincent Lefvre  <vincent (a] vinc17.net>
   28927 
   28928 	Reverted changeset r5355. Better patch to avoid the warnings
   28929 	"warning: label 'addoneulp_doit' defined but not used" in
   28930 	MPFR_RNDRAW_GEN by adding the dummy code in the macro itself.
   28931 
   28932 	Avoid warnings "warning: label 'addoneulp_doit' defined but not used"
   28933 	due to the use of MPFR_RNDRAW_GEN. Dummy source code is inserted, but
   28934 	this is safe, clean (optimized away) and IMHO not too obtrusive.
   28935 
   28936 2008-05-08  Vincent Lefvre  <vincent (a] vinc17.net>
   28937

   28945 2008-04-07  Vincent Lefvre  <vincent (a] vinc17.net>
   28946 
   28947 	tcmp.c: fixed some tests (if mpfr_cmp2 returns an incorrect result,
   28948 	the bug may be some non-reproducible behavior, so don't compute it
   28949 	a second time to say what the value was!) and clean-up.

   29045

   29123 
   29124 	tests/thypot.c: added check_overflow test (currently fails in 32 bits).
   29125 
   29126 	tests/tgeneric.c: added a test that detects suspicious overflows and
   29127 	fails when the overflow flag is not set. This test is enabled only if
   29128 	the MPFR_SUSPICIOUS_OVERFLOW environment variable is set, and shows a
   29129 	bug in mpfr_hypot on 32-bit machines (i.e. when the current exponent
   29130 	range is the maximum exponent range, so that mpfr_check_range() has
   29131 	no effect).
   29132

   29146 	hypot.c: it's better to scale by (Ex + Ey) / 2.
   29147 
   29148 	README.dev: now, the ChangeLog file should be in UTF-8, like in other
   29149 	software (not much difference in practice).
   29150

   29168 2008-02-15  Vincent Lefvre  <vincent (a] vinc17.net>
   29169 
   29170 	For the terminating null pointer of the functions mpfr_inits,
   29171 	mpfr_inits2, mpfr_clears, always use the type mpfr_ptr (no longer
   29172 	void *). Updated the description of these functions in the manual
   29173 	(mpfr.texi). The reason is that the C standard does not guarantee
   29174 	that (void *) 0 has the same representation as a null pointer to
   29175 	a structure (and even the same size). In most C implementations,
   29176 	the representations are the same, but one never knows (dynamical
   29177 	checking is also always possible)...
   29178 	The change has been done with: perl -pi -e \
   29179 	  's/(mpfr_(clear|init)s.*)\(void *\*\) *0\)/$1(mpfr_ptr) 0)/' **/*.c
   29180 	under zsh.

   29258 	of the current range, the exponent range is extended, and restored
   29259 	by the caller once the test has been done.
   29260 	In tests/tacosh.c, changed TEST_RANDOM_EMIN and TEST_RANDOM_EMAX
   29261 	to MPFR_EMAX_MAX for test_generic_huge, so that the intermediate

   29390 	  * Removed the compiler check __MPFR_GNUC(3,3) || __MPFR_ICC(8,1,0)
   29391 	    as this test leaded to both false positives and false negatives
   29392 	    concerning TLS support. Assume that __thread should be used for

   29449 	tests: added trec_sqrt to svn:ignore property.
   29450 
   29451 	mpfr-impl.h: when building MPFR with the GMP build directory,

   29511 2008-01-04  Vincent Lefvre  <vincent (a] vinc17.net>
   29512 
   29513 	Fixed return value of mpfr_strtofr in case of invalid data (it was -1,
   29514 	but it should be 0 since it is a ternary value and the result is 0,
   29515 	which is exact). Added test of the ternary value in this case.
   29516 
   29517 	mpfr.texi: better description of mpfr_strtofr.
   29518 
   29519 	NEWS update (new functions in the trunk).
   29520 
   29521 	Changes related to mpfr_strtofr.
   29522 	  * strtofr.c: for mpfr_strtofr, data corresponding to NaN can now have
   29523 	    an optional sign (since the documentation said that parsing followed
   29524 	    the standard C strtod function and this change makes invalid data
   29525 	    now valid, so that there should be no compatibility problems).
   29526 	  * tests/tstrtofr.c: changed the test for -42P17 in base 16 (this was
   29527 	    eventually regarded as a documentation bug); added tests.
   29528 	  * mpfr.texi: almost completely rewrote the specification of the
   29529 	    mpfr_strtofr function. Changes:
   29530 	    - the binary exponent is now accepted even without the 0b or 0x
   29531 	      prefix;
   29532 	    - data corresponding to NaN can now have an optional sign (this was
   29533 	      a bit ambiguous);
   29534 	    - many other ambiguities avoided.
   29535 
   29536 2008-01-04  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   29537 
   29538 	the function mpfr_mpn_rec_sqrt() provides a faithful approximation of the
   29539 	inverse square root. Some improvements can still be made, but the interface
   29540 	should not change, thus we can start writing the mpfr_rec_sqrt function that
   29541 	calls it.
   29542 
   29543 2008-01-02  Vincent Lefvre  <vincent (a] vinc17.net>
   29544 
   29545 	FAQ update.

   29547 2008-01-01  Vincent Lefvre  <vincent (a] vinc17.net>
   29548 
   29549 	tgamma.c: completed test in r5159 with another one that was failing
   29550 	in the default exponent range.
   29551 
   29552 	delete trailing spaces.
   29553 
   29554 2008-01-01  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   29557 
   29558 2008-01-01  Vincent Lefvre  <vincent (a] vinc17.net>
   29559 
   29560 	gen_inverse.h: fixed the bug reported by Kevin Rauch a few hours ago
   29561 	(and that was detected by the generic tests and by mpfrlint after the
   29562 	latest changes).
   29563 
   29564 	mpfrlint: incorrect use of mpfr_<flag>_p is also checked in .h files.
   29565 
   29566 	Copyright notice update: added 2008 with
   29567 	  perl -pi -e 's/2007 Free Software/2007, 2008 Free Software/' **/*(^/)
   29568 	under zsh.
   29569 
   29570 	tgeneric.c: in the bug detection with flags set before the function
   29571 	call, the erange flag was set, so that no checks were performed on
   29572 	the return value. Fixed that by not setting the erange flag.
   29573 	-> Now, 7 tests fail!
   29574 
   29575 2007-12-31  Vincent Lefvre  <vincent (a] vinc17.net>
   29576 
   29577 	tstrtofr.c: added test of -42P17 with base = 0 and 16. This currently
   29578 	fails with base = 16 (-42P17 is parsed as -0x42P17 instead of -42 with
   29579 	the remaining characters "P17"), but we could alternatively regard the
   29580 	mpfr_strtofr specification (in mpfr.texi) as incorrect.
   29581 
   29582 2007-12-30  Vincent Lefvre  <vincent (a] vinc17.net>
   29583 
   29584 	mpfr.texi: corrections in the specification of mpfr_strtofr (see FIXME).
   29585 
   29586 	strtofr.c: base arguments different from 0 and 2..36 have never been
   29587 	accepted. So, instead of returning the confusing -1 (it's a ternary
   29588 	value), let's add an assert for the moment. An alternative solution
   29589 	is to return 0 and set the erange flag.
   29590 
   29591 	strtofr.c: minor change (in the style); a comment was ambiguous.
   29592 
   29593 2007-12-29  Vincent Lefvre  <vincent (a] vinc17.net>
   29594 
   29595 	TODO update (tests: generic bad cases).

   29612 	texceptions.c: restore the exponent range.
   29613 
   29614 	exp2.c: removed incorrect comment (the overflow test was OK due to the
   29615 	mpfr_clear_flags above, but the new test is slightly better anyway).
   29616 
   29617 2007-12-21  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   29630 	pow.c: detect all underflow cases (some of them were leading to
   29631 	an infinite loop, see bug20071218 in tpow.c).
   29632 
   29633 	mpfr-impl.h: updated description of MPFR_CAN_ROUND.
   29634 
   29635 	round_p.c: in comment, "round to zero" -> "round toward zero".
   29636 
   29637 	tpow.c: formatting.

   29649 2007-12-18  Vincent Lefvre  <vincent (a] vinc17.net>
   29650 
   29651 	Merged the feature-block branch to the trunk:
   29652 	* New MPFR_BLOCK* macros (see mpfr-impl.h) and mpfrlint check to test
   29653 	  exception flags in a more reliable way and detect possible problems
   29654 	  with mpfrlint.
   29655 	* Improved the generic tests (tests/tgeneric.c): for the second
   29656 	  function call, sometimes set all the flags since risk of failures
   29657 	  are known when some flags are already set.
   29658 	* Modified code to use these new MPFR_BLOCK* macros. This fixed bugs
   29659 	  related to exceptions (where flags are set before the call); in
   29660 	  particular, tcot and ty1 failed with the improved generic tests.
   29661

   30031 	tests/tisqrt.c: test the 32-bit __gmpfr_cuberoot bound cases (9 per

   30041 	acinclude.m4: updated comment concerning the checked functions.
   30042 
   30043 	acinclude.m4: added memmove to the checked functions (though this test
   30044 	is currently useless, except for the corresponding information).
   30045 
   30046 	acinclude.m4: updated a comment concerning the function checking.
   30047 
   30048 	gmp_op.c: removed old "#include <stddef.h>" line (seems to be useless
   30049 	now, and note that <stdio.h> is included by default in mpfr-impl.h).
   30050 
   30051 	tests/tj0.c: fixed test.

   30059 	tests/tzeta.c: completed test of mpfr_zeta bug fixed in r4920 (the value
   30060 	of zeta(large negative) was also wrong in GMP_RNDU: -Inf instead of the

   30084 	random functions (mpn_random*, mpz_random*, mpf_random*). Now all tests use
   30085 	either RANDS (which is cleared by tests_rand_end called by tests_end_mpfr),
   30086 	or the gmp_randstate_t mechanism.
   30087 
   30088 2007-11-16  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   30116 
   30117 	pow_z.c: fixed bug that occurs when x is a power of 2 and the result
   30118 	overflows (wrong sign); this bug has always been present (from r3215).
   30119 
   30120 	tpow.c, tpow_z.c: removed a printf that was left by mistake.
   30121 
   30122 	tpow_z.c: added testcase for the latest mpfr_pow bug (rev 4942),
   30123 	which is in fact a bug in mpfr_pow_z.
   30124 
   30125 	tpow.c: added testcase for new bug found by Kevin P. Rauch; removed a
   30126 	mpfr_dump that was left by mistake.

   30137 
   30138 	pow.c: added FIXME comment.
   30139 
   30140 	tpow.c: added testcase for new bug found by Kevin P. Rauch. The problem
   30141 	occurs on x^y with x negative and y an integer whose exponent is > 256
   30142 	(so that mpfr_pow_z isn't used, and the generic code is used instead and
   30143 	fails because x is negative).
   30144 
   30145 2007-11-02  Vincent Lefvre  <vincent (a] vinc17.net>
   30146 
   30147 	Fixed several bugs in mpfr_pow (from rev 3592 and 4932); added testcase.
   30148 
   30149 	tpow.c: added an overflow test in reduced exponent range
   30150 	(-> assertion failure in the current pow.c code).
   30151 
   30152 	mpfr-impl.h: added a comment concerning __gmpfr_one, __gmpfr_two and
   30153 	__gmpfr_four.
   30154 
   30155 	Bug fix: in cmp_abs.c, changed MPFR_GET_EXP into MPFR_EXP to allow
   30156 	exponents outside the current exponent range (needed for mpfr_pow).
   30157 
   30158 2007-10-31  Vincent Lefvre  <vincent (a] vinc17.net>

   30177 	(had to implement a complete loop in that case)
   30178 
   30179 	fixed bug reported by Kevin Rauch: wrong sign for jn(n even, large negative x)
   30180 
   30181 	removed item on mpfr_sinh_cosh (done)
   30182 	added more info on item on efficiency of mpfr_sin
   30183 
   30184 	added comment about function/macro in custom interface

   30186 	jn.c: improved choice of initial precision in Taylor series (takes into
   30187 		account cancellation)
   30188 	tests/tjn.c: now "tjn p n z" evaluates j(n,z) to precision p
   30189 
   30190 2007-10-27  Vincent Lefvre  <vincent (a] vinc17.net>
   30191 
   30192 	factorial.c: added FIXME comment.
   30193 
   30194 	gamma.c: attempt to fix wrong fix in 4918 (the maximum exponent can
   30195 	be > 2^30 on 64-bit machines). There may still be problems in huge
   30196 	precisions.
   30197 
   30198 2007-10-27  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   30207 2007-10-26  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   30232 	subnormal.c: fixed the bugs when old_inex is INT_MIN or INT_MAX.
   30233 
   30234 	tsubnormal.c: added some tests showing bugs when old_inex is INT_MIN
   30235 	or INT_MAX.
   30236 
   30237 	subnormal.c: corrected comment.
   30238 
   30239 	Changeset r4904 introduced an assertion failure, but the assertion
   30240 	emax - emin >= PREC(x) wasn't necessary: the value of emax doesn't
   30241 	matter, except when the exponent is increased due to the rounding.
   30242 	So, we just document that if the result cannot be represented in the
   30243 	current exponent range, the behavior is undefined (updated mpfr.texi
   30244 	accordingly). Removed the assertion from subnormal.c and added a new
   30245 	one to have an abort if such an undefined behavior occurs.

   30442 
   30443 	tsin_cos.c: added test on tiny values.
   30444 
   30445 2007-09-16  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   30446 
   30447 	Put back previous patch, now avoids overflow, and added more explanations.
   30448 	This is still not a definitive solution, but more efficient than 2.3.0
   30449 	in the case x is small.
   30450 
   30451 2007-09-15  Vincent Lefvre  <vincent (a] vinc17.net>

   30570 	tatan.c: added small-value tests in the other rounding modes.
   30571 
   30572 	atan2.c: implemented the special case where x is positive and y/x is
   30573 	computed exactly (solving the underflow problems in this case).
   30574 
   30575 	tatan.c: added a similar test, but with an exact division result.
   30576 
   30577 	tatan.c: fixed test.

   30593 	    with CSS rules.
   30594 	  * Added the list of questions at the top.
   30595 	  * CSS styles: a grey bar is displayed on the left of the target answer
   30596 	    (if the browser supports the ":target" pseudo-class from CSS3).
   30597 
   30598 	faq.xsl: added a comment.
   30599 
   30600 	FAQ update.
   30601 
   30602 2007-08-22  Vincent Lefvre  <vincent (a] vinc17.net>
   30603 
   30604 	INSTALL: added another warning concerning the --with-gmp options.
   30605 	For instance, under Linux, "cpp -I/usr/include -v < /dev/null" says:
   30606 	  ignoring duplicate directory "/usr/include"
   30607 	    as it is a non-system directory that duplicates a system directory
   30608 	and does not modify the include search path as wanted.
   30609 
   30610 2007-08-15  Vincent Lefvre  <vincent (a] vinc17.net>
   30611 
   30612 	mpfr.texi: improved description of mpfr_setsign.
   30613 
   30614 2007-08-14  Vincent Lefvre  <vincent (a] vinc17.net>
   30615 
   30616 	Added to NEWS: Thread-safe support with Microsoft Visual compiler.
   30617 
   30618 	mpfr-impl.h: if MPFR_USE_THREAD_SAFE is defined (--enable-thread-safe):
   30619 	  * Added support for MSC (thanks to Brian Gladman).
   30620 	  * Define MPFR_THREAD_ATTR even after #error to make the error more
   30621 	    visible (see comment in the source).
   30622 
   30623 2007-08-13  Vincent Lefvre  <vincent (a] vinc17.net>
   30624 
   30625 	tstckintc.c: fixed bus error on Solaris (the address of Buffer was not
   30626 	a multiple of 4).
   30627 
   30628 	NEWS: new functions mpfr_signbit, mpfr_setsign, mpfr_copysign.
   30629 
   30630 	Implemented changes suggested in
   30631 	<https://sympa.inria.fr/sympa/arc/mpfr/2007-07/msg00123.html>.
   30632 	* Made mpfr_copysign() like the corresponding function in IEEE 754
   30633 	  (was an internal function until now).
   30634 	* Added mpfr_signbit() and mpfr_setsign().
   30635 	* Documented these three functions.
   30636 	* Updated TODO.
   30637 
   30638 2007-08-11  Vincent Lefvre  <vincent (a] vinc17.net>

   30644 
   30645 2007-08-10  Vincent Lefvre  <vincent (a] vinc17.net>

   30647 	Updated version to 2.4.0-dev.
   30648 
   30649 	NEWS update.
   30650 
   30651 	ChangeLog update with "TZ=UTC svn log -v".
   30652 
   30653 	asinh.c: fixed assertion failure (see test 4 in tasinh.c, added
   30654 	in r4740), that was due to an exception.
   30655 
   30656 	tasinh.c: fixed test.
   30657 
   30658 	tasinh.c: added worst case that yields an assertion failure.
   30659 
   30660 2007-08-09  Vincent Lefvre  <vincent (a] vinc17.net>
   30661 
   30662 	Added data_check support to cbrt.
   30663 
   30664 	log.c: fixed assertion failure (see test x_near_one in tlog.c, added
   30665 	in r4736), that was due to an exception.
   30666 
   30667 	pow.c: added MPFR_SMALL_INPUT_AFTER_SAVE_EXPO for the case where
   30668 	|y * log(x)| is very small (I can't really test because this code
   30669 	currently fails due to a bug in mpfr_log: see test x_near_one
   30670 	added to tlog.c as changeset 4736; this bug is also present in
   30671 	the 2.2 branch).
   30672 
   30673 	tlog.c: added a test leading to an assertion failure in mpfr_log.
   30674 
   30675 	tpow.c: added a test where x is close to 1.
   30676 
   30677 	Added empty file tests/data/exp10 to avoid an error with -dev versions.
   30678 
   30679 	Added a TODO concerning the description of mpfr_round_near_x.

   30681 	Added empty files in tests/data to avoid errors with -dev versions.
   30682 
   30683 	mpfr_ui_pow fix: added a MPFR_SAVE_EXPO_UPDATE_FLAGS.
   30684 
   30685 	Added texp10.c (texp10 currently fails).
   30686 
   30687 	texp2.c: reformat and added some tests which were missing.
   30688 
   30689 2007-08-08  Vincent Lefvre  <vincent (a] vinc17.net>
   30690 
   30691 	Added data_check calls to texpm1, tlog1p and tlog2.
   30692 
   30693 	tests/tests.c: in data_check(), mode 'Z', do not test GMP_RNDN if
   30694 	the precision for the directed rounding modes is MPFR_PREC_MIN.
   30695 
   30696 2007-08-04  Vincent Lefvre  <vincent (a] vinc17.net>
   30697 
   30698 	TODO: more on mpfr_sin (and mpfr_cos).
   30699 
   30700 	TODO: update concerning sin/cos/tan.
   30701 
   30702 2007-08-03  Vincent Lefvre  <vincent (a] vinc17.net>
   30703 
   30704 	tests/tests.c: in data_check(), check the 4 rounding modes if rnd is 'Z'
   30705 	(in order to test the worst cases).
   30706 
   30707 	Fixed coding style (for ansi2knr in particular).
   30708 
   30709 2007-08-02  Vincent Lefvre  <vincent (a] vinc17.net>
   30710 
   30711 	Makefile.am: added a comment about "get_patches.c".
   30712 
   30713 	No longer set "CLEANFILES = get_patches.c" in Makefile.am so that a
   30714 	"make clean" doesn't remove the get_patches.c file, as rebuilding it
   30715 	needs a Unix shell (and some standard utilities). Anyway the update
   30716 	of this file should be regarded as part of the patch process, then
   30717 	this file is just like any other .c files. Note: "make dist" includes
   30718 	this file in the archives, so that concerning the build, everything
   30719 	is like before as long as no patches are applied.
   30720 
   30721 2007-08-01  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   30722 
   30723 	added item about sNaN/qNaN
   30724 
   30725 2007-07-31  Vincent Lefvre  <vincent (a] vinc17.net>
   30726 
   30727 	copysign.c: reformat, updated comment (but this function is still not
   30728 	documented in mpfr.texi).
   30729 
   30730 	Updated version back to 2.3.0-dev since the 2.3 branch will be recreated
   30731 	from the trunk (too many changes!).
   30732 
   30733 	tl2b.c: enable output even when the constants are correct.
   30734 
   30735 	Added get_patches.c to the svn:ignore property, as this file is
   30736 	generated.
   30737 
   30738 	Replaced l2b cache by constants, as suggested by Patrick Pelissier,
   30739 	to avoid efficiency problems with the stack interface and heavily
   30740 	threaded applications.
   30741 	  * Added tests/tl2b.c to generate / check the constants.
   30742 	  * tests/Makefile.am: added tl2b to check_PROGRAMS.
   30743 	  * tests directory: added tl2b to the svn:ignore property.
   30744 	  * mpfr-impl.h: updated the __gmpfr_l2b declaration.
   30745 	  * free_cache.c: disabled free_l2b (since there's no longer a cache).
   30746 	  * get_str.c: added the code generated by tl2b; for the bootstrap, one
   30747 	    can just write:
   30748 	      const __mpfr_struct __gmpfr_l2b[BASE_MAX-1][2] = { { { 0 } } };
   30749 	    Removed the code (in ceil_mul) that computed these constants.
   30750 
   30751 2007-07-30  Vincent Lefvre  <vincent (a] vinc17.net>
   30752 
   30753 	mpfr.texi: updated the documentation of the mpfr_get_d function family.
   30754 
   30755 	Patch tracking: updated README.dev and TODO files.
   30756 
   30757 	Added support for tracking applied patches with new function
   30758 	mpfr_get_patches().
   30759 
   30760 	mpfr.texi: updated the example concerning mpfr_get_version() vs
   30761 	MPFR_VERSION_STRING ("Warning" instead of "Error", make sure that
   30762 	the example fits on 80 columns in the info file).
   30763 
   30764 	mpfr.texi: updated description of mpfr_get_version().
   30765 
   30766 	mpfr.texi: updated description of mpfr_get_version().
   30767 
   30768 2007-07-28  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   30769 
   30770 	added files that are not 100% covered by tests
   30771 
   30772 2007-07-27  Vincent Lefvre  <vincent (a] vinc17.net>
   30773 
   30774 	coverage: added --disable-shared --enable-static to configure.
   30775 
   30776 	mpfr-impl.h: added more casts for g++.
   30777 
   30778 	Reformat.
   30779 
   30780 	Applied patch from Patrick to be able to build MPFR with g++.
   30781 
   30782 2007-07-26  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   30783 
   30784 	added default thresholds for Core 2
   30785 
   30786 2007-07-25  Vincent Lefvre  <vincent (a] vinc17.net>
   30787 
   30788 	No longer use MPFR_CHECK_ALL in tests. In '-dev' versions, assume
   30789 	that the data files exist and return an error whenever a file cannot
   30790 	be opened. In the other versions, return silently if the file cannot

   30805 	representable in a char).
   30806 
   30807 	tests.c: changes in the error messages (BTW, we decided to output
   30808 	everything to stdout for consistency, even though messages for
   30809 	assertion failure are written to stderr) and replaced an abort ()
   30810 	by an exit (1).

   30938 
   30939 	previous bug fix for tiny negative inputs in mpfr_lgamma was incorrect:

   31001 2007-07-03  Vincent Lefvre  <vincent (a] vinc17.net>

   31003 	Fixed the bug reported by David Billinghurst to the MPFR mailing-list
   31004 	on 2007-07-03 (memory leaks under some conditions):
   31005 	  * moved the free_l2b() function from tests/tests.c to free_cache.c;
   31006 	  * mpfr_free_cache() (from free_cache.c) now calls free_l2b();
   31007 	  * as a consequence, no longer call free_l2b() in tests_end_mpfr();
   31008 	  * documented the behavior in mpfr.texi (under mpfr_free_cache).
   31009 
   31010 	tj0.c: added testcase from Sisyphus (assertion failed).

   31046 	fma.c: minor changes for consistency with the future fms.
   31047 
   31048 	Completed the implementation of mpfr_fma (except in some corner cases
   31049 	where overflows/underflows and huge precisions are involved at the
   31050 	same time). Added underflow tests. Removed item from the BUGS file
   31051 	(the remaining problems more or less correspond to the first item).
   31052 
   31053 	Untabified.
   31054 
   31055 	tfma.c: added overflow test to test_underflow.

   31065 
   31066 	BUGS: updated item on mpfr_fma.
   31067 
   31068 	fma.c: completed the cases where x*y/4 needs to be used, except the very
   31069 	particular cases where an underflow occurs, that remain to be done.
   31070 
   31071 	tfma.c: fixed a printf.
   31072 
   31073 	fma.c: added an assertion.

   31078 
   31079 	fma.c: updated a comment.
   31080 
   31081 	tfma.c: added more overflow tests (needed to distinguish the cases
   31082 	where z/4 underflows or not -- see fma.c).
   31083 
   31084 	tfma.c: added tests (-> assertion failed because mpfr_fma implementation
   31085 	isn't complete).
   31086

   31092 
   31093 	BUGS: updated item on the mpfr_acos bug.
   31094 
   31095 	BUGS: updated item on the mpfr_acos test (the bug wasn't visible on
   31096 	32-bit machines due to an integer overflow, but the result should
   31097 	have been correct anyway).
   31098 
   31099 	acos.c: fixed integer overflows; to avoid undefined behavior, I had
   31100 	to add an assertion that is not always satisfied (the code needs to
   31101 	be rewritten to take tiny arguments into account).
   31102 
   31103 	BUGS: update (mpfr_cot has just been fixed).
   31104 
   31105 	cot.c: implemented the case |x| = 2^emin.
   31106 	tests/tcot.c: added tests for this case, in 3 exponent ranges
   31107 	(as this is an overflow limit).
   31108 
   31109 	Fixed bug in div.c: rnd_mode could be modified (MPFR_INVERT_RND), but
   31110 	the original value was assumed in case of underflow or overflow.
   31111 
   31112 	tdiv.c: added a test showing another bug in mpfr_div.
   31113 
   31114 	cot.c: use MPFR_SAVE_EXPO_UPDATE_FLAGS, but the case +/- 2^emin could
   31115 	still be buggy with the current code; added a MPFR_ASSERTN (0) until
   31116 	it is implemented.
   31117 	BUGS: updated item on mpfr_cot.
   31118 
   31119 2007-06-28  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   31120

   31137 	tests/tcoth.c: added underflowed_cothinf test.
   31138 	tests/tsech.c: added overflowed_sech0 test.
   31139 
   31140 	* gen_inverse.h: ACTION_TINY must be called after MPFR_SAVE_EXPO_MARK
   31141 	  (this is necessary for some functions). Moved MPFR_SAVE_EXPO_FREE
   31142 	  after the "end:" label.
   31143 	* coth.c, csc.c, csch.c: as a consequence, MPFR_SAVE_EXPO_UPDATE_FLAGS
   31144 	  had to be added before "goto end;".
   31145 	* sec.c: a rounding mode was incorrect.
   31146 	* tests/tsec.c: added overflowed_sec0 test.
   31147 
   31148 2007-06-21  Vincent Lefvre  <vincent (a] vinc17.net>

   31151 	tests/tsin_cos.c: added overflowed_sin_cos0 test.
   31152 
   31153 	BUGS: Some functions do not use MPFR_SAVE_EXPO_* macros, thus do not
   31154 	behave correctly in a reduced exponent range.
   31155 
   31156 	factorial.c: a rounding mode was incorrect.
   31157 	tests/tfactorial.c: added overflowed_fac0 test.
   31158 
   31159 	exp2.c: use MPFR_SMALL_INPUT_AFTER_SAVE_EXPO instead of
   31160 	MPFR_FAST_COMPUTE_IF_SMALL_INPUT since 1 (__gmpfr_one) isn't
   31161 	necessarily representable.
   31162 	tests/texp2.c: added overflowed_exp2_0 test.
   31163 
   31164 	exp.c: fixed problems in reduced exponent range.
   31165 	tests/texp.c: added overflowed_exp0 test.

   31179 
   31180 	Corrected mpfr_inits, mpfr_inits2 and mpfr_clears calls with NULL
   31181 	argument (-> (void *) 0).
   31182

   31364 	  * Added underflow check.
   31365 
   31366 	Added check of tiny arguments to tgeneric_ui.c (if MPFR_CHECK_TINY is

   31582 	configure.in: improved comment.
   31583 
   31584 	configure.in: added a comment on the AC_ARG_ENABLE(decimal-float...)
   31585 	part. The addition of this code was the cause of the test_CFLAGS problem
   31586 	(see r4425 log), but this code is still wrong.
   31587 
   31588 2007-05-02  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>
   31589

   31593 
   31594 	Removed unused variables.
   31595 
   31596 	get_str.c:
   31597 	  * Removed useless prototype declaration (function no longer defined).
   31598 	  * Fixed initializer.
   31599 
   31600 	configure.in: moved the definition of test_CFLAGS upward (it was
   31601 	always set to "set", either because of things added to configure.in
   31602 	or because of new autoconf).
   31603 
   31604 	mpfr.h: added mpfr_lgamma prototype.
   31605 
   31606 2007-05-02  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   31641 	Re-enable the generic tests when this is done.
   31642 
   31643 	lngamma.c: There was an assertion failed, probably because the error
   31644 	was too large; fixed that by restarting with a larger precision.
   31645 
   31646 	lngamma.c: fixed -2k-1 <= x <= -2k test.
   31647 
   31648 	tests/tlngamma.c: added a test showing a bug in lngamma (due to the
   31649 	use of mpfr_get_si even when the number doesn't fit in a long).
   31650 
   31651 2007-04-22  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   31669 	mpfr_{jn,yn} (mpfr_t res, long n, mpfr_t x, ...), as discussed by
   31670 	mail; fixed a typo in mpfr.texi in mpfr_{y0,y1,yn} description.

   31712 	fixed bug in mpfr_jn_si (forgot to increase working precision)
   31713 
   31714 2007-03-23  Vincent Lefvre  <vincent (a] vinc17.net>

   31814 	added a corresponding testcase in tests/tpow.c.
   31815 
   31816 	pow_si.c: another comment about the overflow detection.
   31817

   31824 	Reimplemented mpfr_set_si_2exp and mpfr_set_ui_2exp, and mpfr_set_si
   31825 	and mpfr_set_ui using the 2exp versions with e = 0. This fixes a bug
   31826 	in corner cases (emin >= 4 and some other constraints) in mpfr_set_si
   31827 	and mpfr_set_ui that incorrectly lead to an underflow flag set, and
   31828 	fixes mpfr_set_si_2exp and mpfr_set_ui_2exp in case of overflow or
   31829 	underflow (replacing the r4346 fix). Added corresponding testcases.

   31847 
   31848 	tests/tget_f.c: fixed a test that had an integer overflow (detected
   31849 	with -ftrapv).
   31850 
   31851 	pow_si.c: Before fixing the bug corresponding to the testcase added in
   31852 	rev 4342, let's fix another one that can be detected with -ftrapv when
   31853 	n = LONG_MIN (since -n is not representable in this case).
   31854 	With wrapping, we always got the correct result because mp_exp_t is
   31855 	currently at most a long *and* because of side effects!
   31856 
   31857 	tests/tpow.c: added a test which fails (undetected integer overflow).
   31858 
   31859 	tests/tpow.c: new test was wrong; fixed.
   31860

   31897 
   31898 	FAQ.html: Added details to MPF-related Q&A's.
   31899 
   31900 	Copyright notice update: added 2007.
   31901 
   31902 	* tests/tests.c: under Linux/x86, the FPU precision can be set before
   31903 	doing the tests (see MPFR_FPU_PREC), so that MPFR can be tested under
   31904 	various FP environments (2 tests currently fail with _FPU_SINGLE).
   31905 	* README.dev: updated "To make a release" section.
   31906 	* BUGS: mentioned the above bug.

   32195 	  * tests/Makefile.am (new-generic-tests branch): run the tests with
   32196 	    MPFR_QUIET=1 to avoid output of useless warnings, as some tests

   32411 
   32412 	BUGS: updated "known bugs" section.
   32413 
   32414 	Fixed an exponent/flags-related bug in lngamma.c.
   32415 
   32416 	Updated svn:ignore property.
   32417 
   32418 2006-08-20  Vincent Lefvre  <vincent (a] vinc17.net>
   32419 
   32420 	Fixed several problems in pow.c concerning underflows, overflows and
   32421 	flags (including the inexact flag, which could be incorrectly set in
   32422 	case of NaN), and added some testcases. Problems in pow_z.c have not
   32423 	been fixed yet.
   32424 
   32425 	Partial fix: The inexact flag was not always set in some functions.
   32426 	In particular, it is now set by mpfr_check_range (if t is not zero)
   32427 	since mpfr_check_range usually comes just after MPFR_SAVE_EXPO_FREE
   32428 	(which restores the previous flags).
   32429 
   32430 2006-08-19  Vincent Lefvre  <vincent (a] vinc17.net>
   32431 
   32432 	Added an assertion for mpfr_exp2 and a test.
   32433 
   32434 2006-08-16  Vincent Lefvre  <vincent (a] vinc17.net>
   32435 
   32436 	Optimized mpfr_expm1 for large (in absolute value) negative values in
   32437 	order to avoid the TMD (the result is very close to -1). Without this
   32438 	patch, mpfr_expm1 could take dozens of MBs and the new generic tests
   32439 	for texpm1 could take several hours instead of less than 1 second.
   32440 
   32441 	Fixed a bug in expm1 for very small negative arguments (and perhaps
   32442 	some very small positive arguments too); this bug is similar to the
   32443 	one in log1p that was recently found and fixed. It was detected by
   32444 	the new generic tests (not committed yet), therefore no testcases
   32445 	are provided. Note: the mpfr_expm1 function is still buggy (freezes
   32446 	on -0.10E18, prec 2 -> prec 13); this is a different bug.
   32447 
   32448 	In mpfr_exp2, the overflow flag was not set if mpfr_exp2 overflowed
   32449 	with x < emax. Added testcase.
   32450 
   32451 2006-08-15  Vincent Lefvre  <vincent (a] vinc17.net>
   32452 
   32453 	The latest mpfr_exp2 fix contained a bug. Partially rewrote mpfr_exp2
   32454 	to fix this bug and another one (and added a corresponding testcase:
   32455 	exp2(10000000000.5), which was freezing).
   32456 
   32457 	Better fix for exp2 exponent range bug.
   32458 
   32459 	Fixed bug in mpfr_exp2 when the argument is an integer and emin > 1.
   32460 	Added a testcase to texp2.
   32461 
   32462 2006-08-14  Vincent Lefvre  <vincent (a] vinc17.net>
   32463 
   32464 	Added tget_ld_2exp to svn:ignore property of "tests" directory
   32465 	(should have been done in rev 4028).
   32466 
   32467 	Fixed bug in log1p for small negative values of x and added testcase.

   32491 	One needs automake 1.6; autoreconf fails with automake 1.4. Adding
   32492 	the 1.6 automake option will make the error message less obfuscated,

   32927 
   32928 	Merged the changes from branch vlefevre:
   32929 	  * mpfr-impl.h: Added MPFR_RNDRAW_GEN based on MPFR_RNDRAW and
   32930 	    MPFR_RNDRAW_EVEN codes, but taking an additional argument: a
   32931 	    handler executed in rounding to nearest mode when the value
   32932 	    is the middle of two consecutive numbers in dest precision.
   32933 	    MPFR_RNDRAW and MPFR_RNDRAW_EVEN are now defined by a "call"
   32934 	    to MPFR_RNDRAW_GEN.
   32935 	  * cache.c: Clean-up and use MPFR_RNDRAW_GEN instead of
   32936 	    MPFR_RNDRAW_EVEN to avoid an unnecessary correction in the
   32937 	    halfway case.
   32938 	  * hypot.c: Fixed mpfr_hypot when the rounding mode is to nearest,
   32939 	    x is "much larger" than y, and x is the middle of two consecutive
   32940 	    numbers in the target precision.
   32941 	  * tests/thypot.c: Added the corresponding testcase.
   32942 
   32943 	[Added during the Subversion to Git conversion]
   32944 	A merge commit could not be generated for Git.

   32957 
   32958 2005-11-02  Vincent Lefvre  <vincent (a] vinc17.net>
   32959 
   32960 	Reverted the latest change to constant.c: removed MPFR_THREAD_ATTR as
   32961 	these constants can be shared. Removed MPFR_THREAD_ATTR from mpfr-impl.h
   32962 	too (this should have been the right correction for rev 3838 concerning
   32963 	the type mismatch). Thanks to Patrick for noticing this.
   32964 
   32965 2005-10-31  Vincent Lefvre  <vincent (a] vinc17.net>

   32980 
   32981 	Fixed MPFR_INT_CEIL_LOG2 (in mpfr-impl.h) and __gmpfr_int_ceil_log2
   32982 	(in int_ceil_log2.c) when the argument is a power of 2, and added a
   32983 	test (new test file tests/tinternals.c). This made a bug appear in
   32984 	div_ui.c and mul_ui.c; fixed that too.

   33047 2005-10-06  Vincent Lefvre  <vincent (a] vinc17.net>
   33048 
   33049 	One of the tests was using the fabs function, but -lm isn't given when

   33103 	Fixed the GMP linking test: replaced __gmp_version, which corresponds
   33104 	to a variable, by __gmpz_init (suggested by the GMP documentation),

   35339 	that infinities are no longer used (this should fix a part of
   35340 	the problem for Visual C++). If IEEE 754 is not supported, one
   35341 	should probably use the standard INFINITY macro instead of
   35342 	(1.0/0.0), since (1.0/0.0) is specific to IEEE 754.
   35343 
   35344 	Applied patch by Steve M. Robbins for non-IRIX MIPS systems
   35345 	(originally for MPFR 2.0.3).

   37074 
   37075 	Infinities are now accepted in mpfr_cmpabs. Updated its definition

   37077 
   37078 2003-10-02  Vincent Lefvre  <vincent (a] vinc17.net>
   37079 
   37080 	Use @url{} for URLs.
   37081 
   37082 	As suggested by PZ:
   37083 	  o documentation of mpfr_fits_* functions moved to the section
   37084 	    on conversions;
   37085 	  o grouped some mpfr_pow special cases;
   37086 	  o explanation concerning the meaning of rnd in mpfr_frac.
   37087 
   37088 	Updated documentation. In particular, mpfr_set_str_raw renamed
   37089 	as mpfr_set_str_binary. This function and mpfr_print_binary are
   37090 	now internal functions. mpfr_print_binary no longer prints the
   37091 	non-significant 0 bits. Updated the source to match the manual.
   37092 	mpfr_print_binary has been completely rewritten (now directly
   37093 	prints to stdout, without using an intermediate string). In
   37094 	mpfr_set_str_binary, replaced atol by strtol + error checking.
   37095 
   37096 2003-10-02  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   37107 
   37108 	Corrections in the MPFR manual (PZ & VL). Functions mpfr_const_pi,

   37115 
   37116 	Added exponent range support.
   37117 
   37118 	Corrections up to Section 5.6 (PZ & VL).
   37119 
   37120 	Re-added the assert on the exponent, but replacing MPFR_EMIN_MIN by
   37121 	MP_EXP_T_MIN (this makes more sense): an assertion failed would mean
   37122 	that the exponent is not representable (an undefined behavior in the
   37123 	ISO C standard). If need be, we could choose to return MP_EXP_T_MIN
   37124 	in such a case, or perhaps MP_EXP_T_MAX to signal an error. The
   37125 	mantissa would still be meaningful.
   37126

   37179 
   37180 	Accept (case-insensitive) NaN and Inf in input for bases <= 16 for
   37181 	backward compatibility in these bases (for bases > 16, we cannot
   37182 	guaranty backward compatibility with the current wanted behavior).
   37183 	Added tests.
   37184 
   37185 2003-09-24  Paul Zimmermann  <Paul.Zimmermann (a] inria.fr>

   37322 
   37323 	Replaced malloc/free by __gmp_allocate_func/__gmp_free_func in
   37324 	mpfr_zeta_pos. zeta.c still uses math (libm) functions -> TODO:
   37325 	remove this dependence.
   37326 
   37327 	Added a test that makes MPFR crash (coming from the mpfr_zeta crash).
   37328 
   37329 	Case that crashes MPFR (coming from test_generic) -> function test1.
   37330 
   37331 	Ended up by simplifying mpfr_ui_pow to fix it completely (with a
   37332 	call to mpfr_pow, in a way similar to other ui functions). There
   37333 	isn't significant differences with the old code anyway, and the
   37334 	case integer^integer wasn't optimized like in mpfr_pow.
   37335 	The test tui_pow now passes, but the test tzeta now fails!
   37336 
   37337 	Code clean-up and reindented. Replaced a 8 by CHAR_BIT,
   37338 	as CHAR_BIT isn't necessarily equal to 8. The bug seems
   37339 	to occur on all machines.
