| Revision | Date | Author | Comments |
| 1.11 | 06-Jun-2008 |
ad | Use a dummy assembly file so we won't try produce lint stuff.
|
| 1.10 | 03-Jun-2008 |
ad | - Fold libm387 into libm.
- Leave libm387 as an empty shell.
|
| 1.9 | 25-Apr-2008 |
christos | branches: 1.9.2;
avoid shadow variables, and enable lint.
|
| 1.8 | 22-Mar-2006 |
drochner | branches: 1.8.18;
merge libc/arch/{i386,x86_64}/gen/modf.S into one
(not quite a merge actually, just an #ifdef for now)
and build it in the i386 case (amd64 should work, just needs to be tested)
That way, a program linking against libm should get the optimized
version as expected.
|
| 1.7 | 28-Jul-2005 |
drochner | activate e_atan2f.S which was there forever but not built, noticed
by Joerg Sonnenberger
|
| 1.6 | 21-Jul-2005 |
rpaulo | Add i387 FPU routines for log2(3) and log2f(3).
ok christos@
|
| 1.5 | 01-Jul-2004 |
drochner | branches: 1.5.2;
provide an assembler implementation of lrint() for i386 and amd64
|
| 1.4 | 19-Aug-2002 |
lukem | Explicitly move setting of NOxxx and USE_SHLIBDIR to the top of the
Makefile (before including <bsd.own.mk>)
|
| 1.3 | 28-Dec-2001 |
lukem | * Add user-controlled mk.conf variables
- SHLIBDIR Location to install shared libraries if ${USE_SHLIBDIR}
is "yes". Defaults to "/usr/lib".
- USE_SHLIBDIR If "yes", install shared libraries in ${SHLIBDIR}
instead of ${LIBDIR}. Defaults to "no".
Sets ${_LIBSODIR} to the appropriate value.
This may be set by individual Makefiles as well.
- SHLINKDIR Location of shared linker. Defaults to "/usr/libexec".
If != "/usr/libexec", change the dynamic-linker
encoded in shared programs
* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
libtermcap libutil libz
* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
to ${_LIBSODIR}/${LIB}.so* for compatibility.
* Always install /sbin/init statically (for now)
The net effect of these changes depends on how the variables are set:
1.) If nothing is set or changed, there is no change from the
current behaviour:
- Static /bin, /sbin, and bits of /usr/*
- Dynamic rest
- Shared linker is /usr/libexec/ld*so
2.) If the following make variables are set:
LDSTATIC=
SHLINKDIR=/lib
SHLIBDIR=/lib
Then the behaviour becomes:
- Dynamic tools
- .so libraries used by /bin and /sbin are installed to /lib,
with symlinks from /usr/lib/lib*so to -> /lib/lib*so
where appropriate
- Shared linker is /lib/ld*so
3.) As per 2.), but add the following variable:
USE_SHLIBDIR=yes
This forces all .so's to be instaleld in /lib (with compat
symlinks), not just those tagged by their Makefiles to be.
Again, compat symlinks are installed

joerg | SSE2 registers are only used for float and double arguments, so update
comment to reflect reality. Add some accessor macros for long double
arguments for i386 and x86_64.
|
| 1.5 | 23-Jun-2008 |
drochner | branches: 1.5.18;
-fix an obvious mistake in fpcw check
-replace ARG_DOUBLE_ONE_HALF by _MSW/_LSW because this reflects the
intention and also matches the terms used in C code,
also make the code where the fpcw overwrites the argument a bit
self-documenting
(this abstraction sucks because it forces to write inefficient code)

| 1.9 | 03-Mar-2014 |
dsl | Drop in a fabs() after the fsqrt().
While it may seem pointless, it the rouding mode is set to round towards
minus infinity then acos(-1) calculates atan2(sqrt(1.0 - 1.0), -1) the subtract
generates -0.0 which sqrt() preserves.
atan2(-0, -1) is -pi, but acos(-1) is expected to be +pi.
This might 'fix' the test failures seen in some environments, but they
are not failing due to an obvously incorrent x87 rounding mode.

drochner | as in exp(), treat +/-Inf and NaN arguments specially, should fix

(We could avoid touching the i387 on amd64 in these cases, but we'd
need to bypass the ABI abstraction macros, so leave it the old way
for now.)

use MKSOFTFLOAT on sh3 instead of assuming softfloat.
standardize on comparing MKSOFTFLOAT with "no".
remove the arm-specific softfloat fenv code (which also had several bugs).
fix logic errors in the arm hardfloat feraiseexcept() and feupdateenv().

riastradh | libm: Fix log-related symbol aliases.
- Do the weak alias dance for log, log2, log10, log1p, and their
f/l variants.
(Not strictly necessary for log2 and log10 since nothing in the
math library itself uses them -- only a computer scientist would
use log2 and only an engineer would use log10 -- but let's just do
it the same for all our forestry.)
- Provide long double aliases on vax.
- Sprinkle RCS ids.

Avoid the PIC dance.
|

|
| 1.11 | 10-Sep-2003 |
wennmach | Reimplement s_log1p.S and s_log1pf.S to use the fyl2xp1 instruction
where necessary.
The log1p() function is provided to compute an accurate value of
log(1 + x), even for tiny values of x. The i387 FPU provides the
fyl2xp1 instruction for this purpose.
However, since the range of the fyl2xp1 function is limited to
-(1 - (sqrt(2) / 2)) <= x <= sqrt(2) - 1
(-0.292893 <= x <= 0.414214)
we need to check if the argument is in the valid range.
In order to reduce the cost for testing the range, we only use
fyl2xp1 if the argument is in the range
-0.25 <= x <= 0.25
which can be checked with just one conditional branch.

jtc | The fyl2xp1 instruction has a limited range:
-(1 - (sqrt(2) / 2)) <= x <= sqrt(2) - 1
so we can't use it.
Also, I'm not sure fyl2xp1's extra precision will
matter once the result is converted from extended
real (80 bits) back to double real (64 bits).
