* Support x86-64 assmebler without AVX512H.J. Lu2016-02-231-16/+24
| | | | | | | | | | | | | | | | When x86-64 assmebler doesn't support AVX512, we should make _dl_runtime_resolve_avx512/_dl_runtime_profile_avx512 as aliases of _dl_runtime_resolve_avx/_dl_runtime_profile_avx. Tested on x86-64 using GCC 5.2 with binutils 20151008 and GCC 4.8 with binutils 20130219. There are no differences in ld.so with binutils 20151008. There are no unexpected failures with binutils 20130219 and 20151008. [BZ #19124] * sysdeps/x86_64/dl-trampoline.S [!HAVE_AVX512_ASM_SUPPORT] (_dl_runtime_resolve_avx512): Make it a hidden alias of _dl_runtime_resolve_avx. (_dl_runtime_profile_avx512): Make it a hidden alias of _dl_runtime_profile_avx.
* Remove incorrect register mov in floorf/nearbyint on x86_64Siddhesh Poyarekar2015-08-142-2/+0
| | | | | | | | | | | | | The change in 0b5395f052ee09cd7e3d219af4e805c38058afb5 replaced calls to __get_cpu_features@plt followed by a mov from rax to rdx, with a single macro LOAD_RTLD_GLOBAL_RO_RDX. It is pretty clear that there was a typo in s_floorf and __nearbyint due to which the (now incorrect) mov was not removed. This patch removes that mov. * sysdeps/x86_64/fpu/multiarch/s_floorf.S (__floorf): Remove unnecessary movq. * sysdeps/x86_64/fpu/multiarch/s_nearbyint.S (__nearbyint): Likewise.
* Don't run tst-getpid2 with LD_BIND_NOW=1H.J. Lu2015-08-051-5/+0
| | | | | | | Since _dl_x86_64_save_sse and _dl_x86_64_restore_sse are removed now, we don't need to run tst-getpid2 with LD_BIND_NOW=1. * sysdeps/unix/sysv/linux/Makefile (tst-getpid2-ENV): Removed.
* Use SSE optimized strcmp in x86-64 ld.soH.J. Lu2015-08-051-253/+216

* Save and restore vector registers in x86-64 ld.soH.J. Lu2015-08-058-501/+472
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch initiaizes GLRO(dl_x86_xstate) in dl_platform_init to indicate if the processor supports SSE, AVX or AVX512. It uses this information to properly save and restore vector registers in ld.so. Now we can use SSE in ld.so and delete FOREIGN_CALL macros.

* hppa: fix sysdep.h header setupMike Frysinger2015-07-293-5/+9
| | | | | | | | | | | | | | | | The semi-recent SYSCALL_CANCEL inclusion broke hppa due to the sysdep.h headers not including the unix/sysdep.h headers. Rework the includes so we match the other ports: * hppa/sysdep.h: - Do not include sys/syscall.h as the unix sysdep.h headers do it. - Do not include config.h as libc-symbols.h does it, and it has no #ifdef multiple-include protection, and it breaks when some files do things like #undef __OPTIMIZE__. * sysdeps/unix/sysv/linux/hppa/sysdep-cancel.h: - Drop the generic/sysdep.h as the unix sysdep.h headers include it. * sysdeps/unix/sysv/linux/hppa/sysdep.h: - Change to the unix & core hppa sysdep header stacks. - Undef a few defines that the core headers already set up for us.
* hppa: rewrite INLINE_SYSCALLMike Frysinger2015-07-291-22/+7
| | | | | | | | | | | | | | | | | | | The semi-recent SYSCALL_CANCEL macro imposes a slight nuance on the implementation of INLINE_SYSCALL: the nr argument cannot be expanded directly but must be passed on to another macro which may expand it. Most arches don't notice because INLINE_SYSCALL is defined in terms of INTERNAL_SYSCALL which has the additional layer of expansion, but on hppa, it was attempting to expand it directly. That causes build errors like so: ../sysdeps/unix/sysv/linux/sigsuspend.c: In function '__sigsuspend': ../sysdeps/unix/sysv/linux/sigsuspend.c:31:62: error: implicit declaration of function 'LOAD_ARGS___SYSCALL_NARGS' ../sysdeps/unix/sysv/linux/sigsuspend.c:31:304: error: called object 'LOAD_ARGS___SYSCALL_NARGS(set, 8)' is not a function So rewrite hppa's INLINE_SYSCALL to use INTERNAL_SYSCALL like other arches do. This is also a nice clean up as the two macros had quite a bit of duplicated logic.
* Extend local PLT reference checkH.J. Lu2015-07-292-3/+24
| | | | | | | | | | | | | | On x86, linker in binutils 2.26 and newer consolidates R_*_JUMP_SLOT with R_*_GLOB_DAT relocation against the same symbol. This patch extends local PLT reference check to support alternate relocations. [BZ #18078] * scripts/check-localplt.awk: Support alternate relocations. * scripts/localplt.awk: Also check relocations in DT_RELA/DT_REL sections. * sysdeps/unix/sysv/linux/i386/localplt.data: Mark free and malloc entries with + REL R_386_GLOB_DAT. * sysdeps/x86_64/localplt.data: New file.

* ia64: drop __tls_get_addr from expected ld.so plt usageMike Frysinger2015-07-281-4/+3
| | | | | | This file was updated with an educated guess as to the symbols needed, but on ia64, we don't have __tls_get_addr calls, so drop it from the list.
* ia64: atomic.h: fix atomic_exchange_and_add 64bit handlingMike Frysinger2015-07-281-3/+1
| | | | | | | | | | | | | | Way back in 2005 the atomic_exchange_and_add function was cleaned up to avoid the explicit size checking and instead let gcc handle things itself. Unfortunately that change ended up leaving beyond a cast to int, even when the incoming value was a long. This has flown under the radar for a long time due to the function not being heavily used in the tree (especially as a full 64bit field), but a recent change to semaphores made some nptl tests fail reliably. This is due to the code packing two 32bit values into one 64bit variable (where the high 32bits contained the number of waiters), and then the whole variable being atomically updated between threads. On ia64, that meant we never atomically updated the count, so sometimes the sem_post would not wake up the waiters.
* ia64: clean up old kernel headers cruftMike Frysinger2015-07-281-4/+0
| | | | | | This define made more sense in the pre-sanitized kernel headers days, but since we require kernel versions that are sanitized, we don't need this hack anymore.

* tile: Fix BZ #18508 (makecontext yield infinite backtrace)Chris Metcalf2015-07-212-4/+6
| | | | | | | | | | | | | | | It turns out tile suffered from the same problem as S390. However, disabling CFI information for the __startcontext on tile was not sufficient to fix the problem; I think the backtracer will just blindly try to follow the link register (lr) in that case. Instead, the change adds a cfi_undefined directive for "lr" and then arranges to call __startcontext directly when the new context starts, rather than just synthesizing a return to it. In addition to being a bit easier now to understand the control flow, this also allows the cfi_undefined directive to be placed in a way that causes it to be in force at the address that the "lr" from the called function points to.
* sparc: fix sigaction for 32bit builds [BZ #18694]Mike Frysinger2015-07-201-0/+4
| | | | | | | | | | | Commit a059d359d86130b5fa74e04a978c8523a0293f77 changed the sigaction struct to pass conform tests, but it ended up also changing the ABI for 32 bit builds. For 64 bit builds, changing the long to two ints works, but for 32 bit builds, it inserts 4 extra bytes. This leads to many packages randomly failing like bash that spews things like: configure: line 471: wait_for: No record of process 0 Bracket the new member by a wordsize check to fix the ABI for 32bit.
