*	configure: fix `test ==` usage gentoo/2.22	Mike Frysinger	2016-04-09	1	-1/+1
\| \| \| \| \| \| \| \|	POSIX defines the = operator, but not ==. Fix the few places where we incorrectly used ==. (cherry picked from commit b2d4456b333970ab4cb01ed8045b9a8d2c4832f3) (cherry picked from commit e2c17de539da301c96afa4181347c63eb94d99b1)
*	Preserve bound registers for pointer pass/return	Igor Zamyatin	2015-07-09	1	-0/+15
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	We need to save/restore bound registers and add a BND prefix before branches in _dl_runtime_profile so that bound registers for pointer pass and return are preserved when LD_AUDIT is used. [BZ #18134] * sysdeps/i386/configure.ac: Set HAVE_MPX_SUPPORT. * sysdeps/i386/configure: Regenerated. * sysdeps/i386/dl-trampoline.S (PRESERVE_BND_REGS_PREFIX): New. (_dl_runtime_profile): Save and restore Intel MPX return bound registers when calling _dl_call_pltexit. Add PRESERVE_BND_REGS_PREFIX before return. * sysdeps/i386/link-defines.sym (LRV_BND0_OFFSET): New. (LRV_BND1_OFFSET): Likewise. * sysdeps/x86/bits/link.h (La_i86_retval): Add lrv_bnd0 and lrv_bnd1. * sysdeps/x86_64/dl-trampoline.S (_dl_runtime_profile): Fix typo in bndmov encoding. * sysdeps/x86_64/dl-trampoline.h: Properly save and restore Intel MPX bound registers. Add PRESERVE_BND_REGS_PREFIX before branch instructions to preserve bounds.
*	Enable AVX2 optimized memset only if -mavx2 works	H.J. Lu	2014-07-14	1	-0/+9
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	* config.h.in (HAVE_AVX2_SUPPORT): New #undef. * sysdeps/i386/configure.ac: Set HAVE_AVX2_SUPPORT and config-cflags-avx2. * sysdeps/x86_64/configure.ac: Likewise. * sysdeps/i386/configure: Regenerated. * sysdeps/x86_64/configure: Likewise. * sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add memset-avx2 only if config-cflags-avx2 is yes. * sysdeps/x86_64/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Tests for memset_chk and memset only if HAVE_AVX2_SUPPORT is defined. * sysdeps/x86_64/multiarch/memset.S: Define multiple versions only if HAVE_AVX2_SUPPORT is defined. * sysdeps/x86_64/multiarch/memset_chk.S: Likewise.
*	Move USE_REGPARMS define to sysdeps/i386/configure.ac.	Joseph Myers	2014-06-25	1	-0/+2
\| \| \| \| \| \| \| \| \| \| \| \| \|	This patch moves the USE_REGPARMS define from the toplevel configure.ac to sysdeps/i386/configure.ac. Tested x86 that the disassembly of installed shared libraries is unchanged by this patch. * configure.ac (USE_REGPARMS): Don't define here. * configure: Regenerated. * sysdeps/i386/configure.ac (USE_REGPARMS): Define here. * sysdeps/i386/configure: Regenerated.
*	rename configure.in to configure.ac	Mike Frysinger	2013-10-30	1	-0/+93
	Autoconf has been deprecating configure.in for quite a long time. Rename all our configure.in and preconfigure.in files to .ac. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
