commit 56f6f6a2403cfa7267cad722597113be35ecf70d
Author: Ulrich Drepper <drepper@gmail.com>
Date: Sat Jan 28 14:48:46 2012 -0500
Use -msse2avx option for x86-64 libm functions
2012-01-28 Ulrich Drepper <drepper@gmail.com>
* config.h.in: Define HAVE_SSE2AVX_SUPPORT.
* math/math_private.h: Remove libc_fegetround* and
libc_fesetround*.
* sysdeps/i386/configure.in: Check for -msse2avx.
* sysdeps/x86_64/fpu/math_private.h: Use VEX-encoded instructions
also if SSE2AVX is defined.
Remove libc_fegetround* and libc_fesetround*.
* sysdeps/x86_64/fpu/multiarch/Makefile: Compile *-avx functions
if config-cflags-sse2avx is yes. Also add -DSSE2AVX to defines.
* sysdeps/x86_64/fpu/multiarch/e_atan2.c: Use HAS_AVX again instead
of HAS_YMM_USABLE.
* sysdeps/x86_64/fpu/multiarch/e_exp.c: Likewise.
* sysdeps/x86_64/fpu/multiarch/e_log.c: Likewise.
* sysdeps/x86_64/fpu/multiarch/s_atan.c: Likewise.
* sysdeps/x86_64/fpu/multiarch/s_sin.c: Likewise.
* sysdeps/x86_64/fpu/multiarch/s_tan.c: Likewise.

Reset bit_AVX in __cpu_features is OS support is missing
2012-01-26 Ulrich Drepper <drepper@gmail.com>
[BZ #13583]
* sysdeps/x86_64/multiarch/init-arch.h: Define bit_OSXSAVE.
* sysdeps/x86_64/multiarch/init-arch.c (__init_cpu_features): If
bit_AVX is set also check OSXAVE/XCR0 and reset bit_AVX if necessary.
Also contains selected changes from commits 08cf777f9e7f6d826658a99c7d77a359f73a45bf
and 56f6f6a2403cfa7267cad722597113be35ecf70d.
