* More strict check of AVX512 support in assembler.Andrew Senkevich2015-06-111-0/+1
| | | | | | | | Binutils 2.24 doesn't support some AVX512 instructions with ZMM registers, so we need add more strict check. * configure.ac: Added more strict check. * configure: Regenerated.
* Start of series of patches with x86_64 vector math functions.Andrew Senkevich2015-06-091-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here is implementation of cos containing SSE, AVX, AVX2 and AVX512 versions according to Vector ABI which had been discussed in <https://groups.google.com/forum/#!topic/x86-64-abi/LmppCfN1rZ4>.

* Save/restore bound registers in _dl_runtime_resolveIgor Zamyatin2014-04-091-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch saves and restores bound registers in symbol lookup for x86-64: 1. Branches without BND prefix clear bound registers. 2. x86-64 pass bounds in bound registers as specified in MPX psABI extension on hjl/mpx/master branch at https://github.com/hjl-tools/x86-64-psABI https://groups.google.com/forum/#!topic/x86-64-abi/KFsB0XTgWYc Binutils has been updated to create an alternate PLT to add BND prefix when branching to ld.so. * config.h.in (HAVE_MPX_SUPPORT): New #undef. * sysdeps/x86_64/configure.ac: Set HAVE_MPX_SUPPORT. * sysdeps/x86_64/configure: Regenerated. * sysdeps/x86_64/dl-trampoline.S (REGISTER_SAVE_AREA): New macro.

* Check AVX-512 assembler support firstH.J. Lu2014-03-141-26/+26
| | | | | | | | | | | It checks AVX-512 assembler support first and sets libc_cv_cc_avx512 to $libc_cv_asm_avx512, instead of yes. GCC won't support AVX-512 if assembler doesn't support it. * sysdeps/x86_64/configure.ac: Check AVX-512 assembler support first. Disable AVX-512 GCC support if assembler doesn't support it. * sysdeps/x86_64/configure: Regenerated.
* Save and restore AVX-512 zmm registers to x86-64 ld.soIgor Zamyatin2014-03-131-0/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AVX-512 ISA adds 512-bit zmm registers. This patch updates _dl_runtime_profile to pass zmm registers to run-time audit. It also changes _dl_x86_64_save_sse and _dl_x86_64_restore_sse to upport zmm registers, which are called when only when RTLD_PREPARE_FOREIGN_CALL is used. Its performance impact is minimum. * config.h.in (HAVE_AVX512_SUPPORT): New #undef. (HAVE_AVX512_ASM_SUPPORT): Likewise. * sysdeps/x86_64/bits/link.h (La_x86_64_zmm): New.

* rename configure.in to configure.acMike Frysinger2013-10-301-1/+1
| | | | | | | 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>

| | | | | | | | Pretty sure we require recent enough versions of gcc/binutils to make this check pointless. I can't any logs in the last few years where this check didn't return "yes". Signed-off-by: Mike Frysinger <vapier@gentoo.org>
