* x86-64: Verify that _dl_runtime_resolve preserves vector registersH.J. Lu2017-02-091-4/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | On x86-64, _dl_runtime_resolve must preserve the first 8 vector registers. Add 3 _dl_runtime_resolve tests to verify that SSE, AVX and AVX512 registers are preserved. * sysdeps/x86_64/Makefile (tests): Add tst-sse, tst-avx and tst-avx512. (test-extras): Add tst-avx-aux and tst-avx512-aux. (extra-test-objs): Add tst-avx-aux.o and tst-avx512-aux.o. (modules-names): Add tst-ssemod, tst-avxmod and tst-avx512mod.

* x86_64: tst-quad1pie, tst-quad2pie: compile with -fPIE [BZ #7065]Nick Alcock2016-12-211-0/+3
| | | | | | With stack protection enabled, these files have external symbol references for the first time, so the fact that they are not compiled with -fPIE and are then linked into a -pie binary starts to hurt.
* Register extra test objectsAndreas Schwab2016-04-131-0/+4
| | | | | This makes sure that the extra test objects are compiled with the correct MODULE_NAME and dependencies are tracked.
* tst-audit4, tst-audit10: Compile AVX/AVX-512 code separately [BZ #19269]Florian Weimer2016-03-071-4/+4
| | | | | This ensures that GCC will not use unsupported instructions before the run-time check to ensure support.
* Add a comment in sysdeps/x86_64/MakefileH.J. Lu2016-03-041-0/+3
| | | | | | Mention recursive calls when ENTRY is used in _mcount.S. * sysdeps/x86_64/Makefile (sysdep_noprof): Add a comment.
* Copy x86_64 _mcount.op from _mcount.oH.J. Lu2016-03-031-0/+1
| | | | | | | | No need to compile x86_64 _mcount.S with -pg. We can just copy the normal static object. * gmon/Makefile (noprof): Add $(sysdep_noprof). * sysdeps/x86_64/Makefile (sysdep_noprof): Add _mcount.
* Remove configure tests for -mno-vzeroupper support.Joseph Myers2015-10-091-4/+1
| | | | | | | | | | | | | | | | | | GCC added support for -mno-vzeroupper in version 4.6. Thus the configure tests for this support are obsolete, and this patch removes them. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by this patch). * sysdeps/i386/configure.ac (libc_cv_cc_novzeroupper): Remove configure test. * sysdeps/i386/configure: Regenerated. * sysdeps/x86_64/configure.ac (libc_cv_cc_novzeroupper): Remove configure test. * sysdeps/x86_64/configure: Regenerated. * sysdeps/x86_64/Makefile [$(config-cflags-novzeroupper) = yes]: Make code unconditional.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC added support for -mavx and -msse2avx in version 4.4.

| | | | | | | | | | | | | | | | Since x86-64 ld.so preserves vector registers now, we can use SSE in x86-64 ld.so.

* Save and restore vector registers in x86-64 ld.soH.J. Lu2015-08-251-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds SSE, AVX and AVX512 versions of _dl_runtime_resolve and _dl_runtime_profile, which save and restore the first 8 vector registers used for parameter passing. elf_machine_runtime_setup selects the proper _dl_runtime_resolve or _dl_runtime_profile based on _dl_x86_cpu_features. It avoids race condition caused by FOREIGN_CALL macros, which are only used for x86-64. Performance impact of saving and restoring 8 vector registers are negligible on Nehalem, Sandy Bridge, Ivy Bridge and Haswell when ld.so is optimized with SSE2. [BZ #15128] * sysdeps/x86_64/Makefile [$(subdir) == elf] (tests): Add ifuncmain8. (modules-names): Add ifuncmod8. ($(objpfx)ifuncmain8): New rule. * sysdeps/x86_64/dl-machine.h: Include <dl-procinfo.h> and <cpuid.h>. (elf_machine_runtime_setup): Use _dl_runtime_resolve_sse, _dl_runtime_resolve_avx, or _dl_runtime_resolve_avx512, _dl_runtime_profile_sse, _dl_runtime_profile_avx, or _dl_runtime_profile_avx512, based on HAS_ARCH_FEATURE. * sysdeps/x86_64/dl-trampoline.S: Rewrite. * sysdeps/x86_64/dl-trampoline.h: Likewise. * sysdeps/x86_64/ifuncmain8.c: New file. * sysdeps/x86_64/ifuncmod8.c: Likewise. * sysdeps/x86_64/nptl/tcb-offsets.sym (RTLD_SAVESPACE_SSE): Removed. * sysdeps/x86_64/nptl/tls.h (__128bits): Removed.

[BZ #14341] * elf/dynamic-link.h (elf_machine_lazy_rel): Properly handle the case when there is a gap between DT_REL and DT_JMPREL sections. * sysdeps/x86_64/Makefile (tests): Add tst-split-dynreloc.

* Save and restore AVX-512 zmm registers to x86-64 ld.soIgor Zamyatin2014-03-131-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Refine testing for xmm/ymm register use in x86-64 ld.so.Ulrich Drepper2009-07-271-0/+1
| | | | | | | | | The test now takes the callgraph into account. Only code called during runtime relocation is affected by the limitation. We now determine the affected object files as closely as possible from the outside. This allowed to remove some the specializations for some of the string functions as they are only used in other code paths.
* Make sure no code in ld.so uses xmm/ymm registers on x86-64.Ulrich Drepper2009-07-261-0/+4
| | | | | | | | | | This patch introduces a test to make sure no function modifies the xmm/ymm registers. With the exception of the auditing functions. The test is probably too pessimistic. All code linked into ld.so is checked. Perhaps at some point the callgraph starting from _dl_fixup and _dl_profile_fixup is checked and we can start using faster SSE-using functions in parts of ld.so.
