Igor Zamyatin 2d63a517e4 Save and restore AVX-512 zmm registers to x86-64 ld.so ... 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. (La_x86_64_vector): Add zmm. * sysdeps/x86_64/Makefile (tests): Add tst-audit10. (modules-names): Add tst-auditmod10a and tst-auditmod10b. ($(objpfx)tst-audit10): New target. ($(objpfx)tst-audit10.out): Likewise. (tst-audit10-ENV): New. (AVX512-CFLAGS): Likewise. (CFLAGS-tst-audit10.c): Likewise. (CFLAGS-tst-auditmod10a.c): Likewise. (CFLAGS-tst-auditmod10b.c): Likewise. * sysdeps/x86_64/configure.ac: Set config-cflags-avx512, HAVE_AVX512_SUPPORT and HAVE_AVX512_ASM_SUPPORT. * sysdeps/x86_64/configure: Regenerated. * sysdeps/x86_64/dl-trampoline.S (_dl_runtime_profile): Add AVX-512 zmm register support. (_dl_x86_64_save_sse): Likewise. (_dl_x86_64_restore_sse): Likewise. * sysdeps/x86_64/dl-trampoline.h: Updated to support different size vector registers. * sysdeps/x86_64/link-defines.sym (YMM_SIZE): New. (ZMM_SIZE): Likewise. * sysdeps/x86_64/tst-audit10.c: New file. * sysdeps/x86_64/tst-auditmod10a.c: Likewise. * sysdeps/x86_64/tst-auditmod10b.c: Likewise.		2014-03-13 11:19:08 -07:00
