| Revision | Date | Author | Comments |
| 1.3 | 05-Nov-1997 |
cgd | remove these, they are no longer necessary or appropriate
|
| 1.2 | 13-Jul-1997 |
christos | branches: 1.2.2;
Add missing stdlib.h include
|
| 1.1 | 22-Dec-1996 |
cgd | File which provides lint stubs for the functions defined by
machine-dependent assembly code, whose source files live in its directory.
(Not necessarily complete yet.)
|
| 1.2.2.1 | 08-Nov-1997 |
thorpej | Pull up from trunk: "...hey hey hey, goodbye!"
|
| 1.22 | 06-Dec-2009 |
uebayasi | Rename ${SRCS.{alpha,arm,...}.gen} to ${LSRCS.{alpha,arm,...}.gen} because
they ended up in ${LSRCS}, not ${SRCS}. ${SRCS.*} namespace will be used
for more useful things. No functional changes intended.
|
| 1.21 | 28-Jun-2006 |
drochner | build frexp/ldexp/modf in the "compat" part
(code is identical)
|
| 1.20 | 16-Sep-2005 |
drochner | some stuff went to compat
|
| 1.19 | 15-Apr-2005 |
kleink | Push back the descriptions of NaN formats, and descriptions of the
distinction between signalling NaNs and quiet NaNs back into the
machine-dependent headers; treat the implementation of __nanf in the
same spirit.
IEEE 754 leaves the distinction between signalling NaNs and quiet NANs
to the implementation, and unlike our headers used to suggest they're
not identical in the interpretation of the fraction's MSb; in due
course, make those of hppa, mips, sh3, and sh5 reflect reality.
|
| 1.18 | 04-Mar-2004 |
kleink | branches: 1.18.6;
* Turn isinf(3) and isnan(3) into C99-style macros.
* Make it possible for ports to override these (i.e., VAX).
* Remove isnanl(), which was internal to libc only.
|
| 1.17 | 01-Mar-2004 |
drochner | we need a silly trampoline to make _resumecontext work
|
| 1.16 | 15-Jan-2004 |
kleink | Add C99 fpclassify(), isfinite(), isnormal(), and signbit() macros.
|
| 1.15 | 25-Oct-2003 |
kleink | Add __infinityf and __infinityl, float respectively long double analogs
of __infinity.
|
| 1.14 | 24-Oct-2003 |
kleink | * Since there is no single portable IEEE 754 format for a long double,
keep a common implementation of isinfl() and isnanl() to be used by
platforms where `long double' == `double'; move others into
machine-dependent code.
* In due course, consider __VFP_FP__ on arm.
|
| 1.13 | 01-Aug-2003 |
lukem | Rework how dependency generation is performed:
* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
This is a change of behaviour. If a Makefile wants the clean semantics
it must specifically append to CLEANFILES.
Resolves PR toolchain/5204.
* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
that have a suffix of: .c .m .s .S .C .cc .cpp .cxx
* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES
* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}
* Deprecate the (short lived) DEPENDSRCS
Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.
Tested with "make -j 8 distribution" and "make distribution".
|
| 1.12 | 17-May-2003 |
thorpej | Build _isinfl() and _isnanl().
|
| 1.11 | 12-May-2003 |
kleink | Rename ieee754_function.c to function_ieee754.c, following the convention
used in exec_format.c, loadfile_format.c, subsys_machdep.c etc.
Per discussion with Christos.
|
| 1.10 | 21-Jan-2003 |
kleink | Add swapcontext() lint stub.
|
| 1.9 | 18-Jan-2003 |
thorpej | Merge the nathanw_sa branch.
|
| 1.8 | 19-Feb-2002 |
simonb | Clean up some rampant code duplication wrt ieee number handling:
- Add alignment-safe double and float unions.
- Use the above for the __infinity and __nan constants on all
architectures that use the standard ieee754 representation of
those constants.
- Add a single copy of various ieee754 math functions (frexp, isinf,
isnan, ldexp and modf) that had numerous duplicates among the
arch-specific directories.
- Use the above functions on all architectures where the generic C
versions where used. Architectures that had local assembly
routines are untouched (for those functions only).
|
| 1.7 | 23-Dec-1999 |
kleink | branches: 1.7.6;
C99: Define a NAN macro in <math.h> which evaulates to a constant expression of
a single-precision quiet NaN; only to be defined on platforms that do support
this value.
|
| 1.6 | 29-Aug-1999 |
mycroft | Separate isnan() into a separate module, and make isinf()/isnan() use ieee.h.
|
| 1.5 | 15-Jan-1999 |
bouyer | Move the bswap functions from libutil to libc (this bups the
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.
|
| 1.4 | 29-Sep-1998 |

thorpej | POSIX sez:
The longjmp() function shall not cause setjmp() to return 0; if val
is 0, setjmp() shall return 1.
Fixes the _longjmp_zero and longjmp_zero test cases in the t_setjmp
test on alpha.
|
| 1.7 | 13-Mar-2013 |
martin | branches: 1.7.36;
Remove clearing of ucontext_t, the only random register values now are
argument and scratch registers (which will be reloaded after return anyway).
|
| 1.6 | 12-Mar-2013 |
martin | Save the GP register value and restore it on longjmp.
While formally GP is not a callee-saved register, for static linking
the link time optimization described in section 3.2.3 of the "Calling
Standard for Alpha Systems" allows the caller to rely on GP being the
value needed within setjmp() - and not restore it after return if setjmp
and the call site share a GP value.
This fixes longjmp/setjmp for statically linked programs, e.g. /rescue/csh
or the static tcsh variant from pkgsrc.

thorpej | - Consistently use _REG_* defines from assym.h to mean register numbers,

hard-code magic numbers.

Use excb before and after the mt_fpcr/mf_fpcr instructions as specified
in the alpha ARM 4.7.8.1 (Accessing the FPCR):
Because Alpha floating-point hardware can overlap the execution of
a number of floating-point instructions, accessing the FPCR must
be synchronized with other floating-point instructions. An EXCB
instruction must be issued both prior to and after accessing the
FPCR to ensure that the FPCR access is synchronized with the
execution of previous and subsequent floating-point instructions;
otherwise synchronization is not ensured.
Use unions to convert between double and uint64_t to avoid casting.

Allow storing and receiving the LWP private pointer via ucontext_t
on all platforms except VAX and IA64. Add fast access via register for
AMD64, i386 and SH3 ports. Use this fast access in libpthread to replace
the stack based pthread_self(). Implement skeleton support for Alpha,
HPPA, PowerPC, SPARC and SPARC64, but leave it disabled.
Ports that support this feature provide __HAVE____LWP_GETPRIVATE_FAST in
machine/types.h and a corresponding __lwp_getprivate_fast in
machine/mcontext.h.
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

riastradh | On ports without __HAVE_LONG_DOUBLE, make fabsl alias fabs.
For some reason, fabs lives in libc, not in libm, and our tests now
detect when fabs or fabsl is missing from libm. For those ports that
sometimes have long double and sometimes don't, make it conditional.
Still missing: fabs _and_ fabsl on ia64. Need help from an itanium
wizard! Other portmasters: Please take a look and see if I missed
any ports that might have long double where this alias will not work.

Because Alpha floating-point hardware can overlap the execution of
a number of floating-point instructions, accessing the FPCR must
be synchronized with other floating-point instructions. An EXCB
instruction must be issued both prior to and after accessing the
FPCR to ensure that the FPCR access is synchronized with the
execution of previous and subsequent floating-point instructions;
otherwise synchronization is not ensured.

IEEE 754 leaves the distinction between signalling NaNs and quiet NANs
to the implementation, and unlike our headers used to suggest they're
not identical in the interpretation of the fraction's MSb; in due
course, make those of hppa, mips, sh3, and sh5 reflect reality.

-check for a NULL uc_link before calling setcontext(2); do a real exit(3)
instead with exit handlers and all that
-If setcontext(2) returns (which it shouldn't), do an _exit(-1) rather
than relying on a sensible return value to use as exit code. Makes
it less likely that an ucontext corruption goes unnoticed.
