* configure: fix `test ==` usageMike Frysinger2016-04-091-2/+2
| | | | | POSIX defines the = operator, but not ==. Fix the few places where we incorrectly used ==.
* Remove cpuid.h configure tests.Joseph Myers2015-10-291-4/+0
| | | | | | | | | | | | | | There are configure tests for the cpuid.h header for x86 / x86_64. GCC 4.3 and later install this header, so those tests are obsolete. This patch removes them. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). * sysdeps/i386/configure.ac (cpuid.h): Do not test for header. * sysdeps/i386/configure: Regenerated. * sysdeps/x86_64/configure.ac (cpuid.h): Do not test for header. * sysdeps/x86_64/configure: Regenerated.
* Remove -mavx2 configure tests.Joseph Myers2015-10-281-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | There are configure tests for the -mavx2 compiler option. AVX2 support was added in GCC 4.7, so these tests are now obsolete; this patch removes them. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * sysdeps/i386/configure.ac (libc_cv_cc_avx2): Remove configure test. * sysdeps/i386/configure: Regenerated. * sysdeps/x86_64/configure.ac (libc_cv_cc_avx2): Remove configure test. * sysdeps/x86_64/configure: Regenerated. * config.h.in (HAVE_AVX2_SUPPORT): Remove #undef. * sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add memset-avx2 unconditionally instead of conditionally on [$(config-cflags-avx2) = yes]. * sysdeps/x86_64/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list) [HAVE_AVX2_SUPPORT]: Make code unconditional. * sysdeps/x86_64/multiarch/memset.S [HAVE_AVX2_SUPPORT]: Likewise. * sysdeps/x86_64/multiarch/memset_chk.S [IS_IN (libc) && SHARED && HAVE_AVX2_SUPPORT]: Change conditional to [IS_IN (libc) && SHARED].

| | | | | | | | | | | | | | | | | | GCC added support for -mno-vzeroupper in version 4.6. Thus the configure tests for this support are obsolete, and this patch removes them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC added support for -mfma4 in version 4.5.
