commit 08cf777f9e7f6d826658a99c7d77a359f73a45bf
Author: Ulrich Drepper <drepper@gmail.com>
Date: Thu Jan 26 09:45:54 2012 -0500
Really fix AVX tests
There is no problem with strcmp, it doesn't use the YMM registers.
The math routines might since gcc perhaps generates such code.
Introduce bit_YMM_USBALE and use it in the math routines.
[BZ #13583]
* sysdeps/x86_64/multiarch/init-arch.h: Define bit_OSXSAVE.
Clean up HAS_* macros.
* sysdeps/x86_64/multiarch/init-arch.c (__init_cpu_features): If
bit_AVX is set also check OSXAVE/XCR0 and set bit_YMM_Usable if
possible.
* sysdeps/x86_64/fpu/multiarch/e_atan2.c: Use HAS_YMM_USABLE, not
HAS_AVX.
* sysdeps/x86_64/fpu/multiarch/e_exp.c: Likewise.

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.

Author: Ulrich Drepper <drepper@gmail.com>
Date: Mon Oct 31 01:51:16 2011 -0400
Cache network interface information
Whenever getaddrinfo needed network interface information it used the
netlink interface to read the information every single time. The
problem is that this information can change at any time.
The patch implements monitoring of the network interfaces through
nscd. If no change is detected the previously read information can
be reused (which is the norm). This timestamp information is also
made available to other processes using the shared memory segment
between nscd and those processes.
2011-10-31 Ulrich Drepper <drepper@gmail.com>
* include/ifaddrs.h: Declare __free_in6ai and __bump_nl_timestamp.
* inet/check_pf.c: Provide dummy versions of __free_in6ai and
__bump_nl_timestamp.
* nscd/connections (nscd_init): When host database is served open
netlink socket and request notification about configuration changes.
(main_loop_poll): Track netlink file descriptor and bump timestamp
in case data becomes available.
(main_loop_epoll): Likewise.
* nscd/nscd-client.h (DB_VERSION): Bump to 2.
(database_pers_head): Add extra_data fileds.
Declare __nscd_get_mapping and __nscd_get_nl_timestamp.
* nscd/nscd_gethst_r.c (__nscd_get_nl_timestamp): New function.
* nscd/nscd_helper.c (__nscd_get_mapping): Renamed from get_mapping.
Adjust caller.
* sysdeps/posix/getaddrinfo.c (getaddrinfo): Don't call free on
in6ai data, call __free_in6ai.
* sysdeps/unix/sysv/linux/Makefile [subdir=nscd] (sysdep-CFLAGS):
Add -DHAVE_NETLINK.
* sysdeps/unix/sysv/linux/check_pf.c: Major rewrite. Cache the
interface information. Reuse previous data if netlink timestamp
is not changed.
(__bump_nl_timestamp): New function.
(__free_in6ai): New function.
