2015-08-05Improve fesetenv performance by avoiding unnecessary FPSR/FPCR reads/writes.Wilco Dijkstra1-17/+23
It uses the same logic as the ARM version. The common case removes 1 FPSR and 1 FPCR read. For FE_DFL_ENV and FE_NOMASK_ENV a FPCR read is avoided in case the FPCR does not change.
2015-08-05Fix powf (close to -1, large) (bug 18647).Joseph Myers1-1/+1
The flt-32 implementation of powf wrongly uses x-1 instead of |x|-1 when computing log (x) for the case where |x| is close to 1 and y is large. This patch fixes the logic accordingly. Relevant tests existed for x close to 1, and corresponding tests are added for x close to -1, as well as for some new variant cases. Tested for x86_64 and x86. [BZ #18647] * sysdeps/ieee754/flt-32/e_powf.c (__ieee754_powf): For large y and |x| close to 1, use absolute value of x when computing log. * math/auto-libm-test-in: Add more tests of pow. * math/auto-libm-test-out: Regenerated.
2015-08-05arm: Assembly implementation cleanupAdhemerval Zanella3-136/+18
This patch removes arm assembly implementation of mmap and mmap64. The new implementation used is the wordsize-32 generic linux one. Tested on armhf.
2015-08-05mmap64: fix undef warningsMike Frysinger1-3/+3
The only target that defines this is m68k, so move the existing fallback define up to avoid warnings on other systems.
2015-08-04tilepro: fix warnings in sysdeps/tile/tilepro/bits/atomic.hChris Metcalf1-8/+12
Using a ({ }) structure avoids the "value computed is not used" that a simple () structure causes.

2015-07-30Prevent runtime fail of SSE vector math tests on non SSE4.1 machine.Andrew Senkevich1-2/+0
[BZ #18740] * sysdeps/x86_64/fpu/Makefile (double-vlen2-arch-ext-cflags, float-vlen4-arch-ext-cflags): Removed. * math/Makefile (CFLAGS-test-double-vlen2-wrappers.c, CFLAGS-test-float-vlen4-wrappers.c): Likewise.
2015-07-30hppa: fix pthreadtypes.h namespace failuresMike Frysinger1-3/+3
The conform tests flag the "aligned" symbol used inside the attributes, so rename it to __aligned__ like other headers.
2015-07-30hppa: Remove custom lowlevellock.h.Torvald Riegel1-334/+0
This untested patch removes the custom lowlevellock.h on hppa. It seems to contain an implementation equivalent to the generic lowlevellock.h.
2015-07-29hppa: sigaction.h: change sa_flags to an intMike Frysinger1-1/+6
This fixes the conform test for the sigaction.h header and makes it match all the other arches.
2015-07-29hppa: fix sysdep.h header setupMike Frysinger3-5/+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.
2015-07-29hppa: rewrite INLINE_SYSCALLMike Frysinger1-22/+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.
2015-07-29Extend local PLT reference checkH.J. Lu2-3/+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.
2015-07-29Added runtime check for AVX vector math tests.Andrew Senkevich3-1/+27
[BZ #18731] * sysdeps/x86_64/fpu/math-tests-arch.h: Added AVX runtime check. * sysdeps/x86_64/fpu/test-double-vlen4.c: Likewise. * sysdeps/x86_64/fpu/test-float-vlen8.c: Likewise.
2015-07-28ia64: drop __tls_get_addr from expected ld.so plt usageMike Frysinger1-4/+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.
2015-07-28ia64: atomic.h: fix atomic_exchange_and_add 64bit handlingMike Frysinger1-3/+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.
2015-07-28ia64: clean up old kernel headers cruftMike Frysinger1-4/+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.

2015-07-24[ARM][BZ #17711] Fix extern protected data handlingSzabolcs Nagy2-3/+9
Fixes elf/tst-protected1a and elf/tst-protected1b tests.

2015-07-23ia64: sigaction.h: fix sa_flags orderingMike Frysinger1-1/+1
Since ia64 is little endian, sa_flags has to come before the padding when splitting it from 64bits to 32bits. Reported-by: Joseph Myers <joseph@codesourcery.com>
2015-07-21ia64: msg.h: fix msg_qnum/msg_qbytes typesMike Frysinger1-4/+9
These two fields have dedicated types, so change the ia64 header to match all the other arches. This fixes the conform test for msg.h.

2015-07-21tile: Fix BZ #18508 (makecontext yield infinite backtrace)Chris Metcalf2-4/+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.
2015-07-20sparc: fix sigaction for 32bit builds [BZ #18694]Mike Frysinger1-0/+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.

2015-07-20Add si_addr_bnd to _sigfault in x86 struct siginfoH.J. Lu1-0/+7
X86 struct siginfo in kernel 3.19 has been changed by commit ee1b58d36aa1b5a79eaba11f5c3633c88231da83 Author: Qiaowei Ren <qiaowei.ren@intel.com> Date: Fri Nov 14 07:18:19 2014 -0800 mpx: Extend siginfo structure to include bound violation information This patch adds new fields about bound violation into siginfo structure. si_lower and si_upper are respectively lower bound and upper bound when bound violation is caused. This patch updates x86 struct siginfo to enable GDB with MPX support. [BZ #18696] * sysdeps/unix/sysv/linux/x86/bits/siginfo.h (_sigfault): Add si_addr_bnd. (si_lower): New. (si_upper): Likewise.

This patch optimizes strstr function for power >= 7 systems. Performance gain is obtained using aligned memory access and usage of cmpb instruction for quicker comparison. The average improvement of this optimization is ~40%. Tested on ppc64 and ppc64le. 2015-07-16 Rajalakshmi Srinivasaraghavan <raji@linux.vnet.ibm.com> * sysdeps/powerpc/powerpc64/multiarch/Makefile: Add strstr(). * sysdeps/powerpc/powerpc64/multiarch/ifunc-impl-list.c: Likewise. * sysdeps/powerpc/powerpc64/power7/strstr.S: New File. * sysdeps/powerpc/powerpc64/multiarch/strstr-power7.S: New File. * sysdeps/powerpc/powerpc64/multiarch/strstr-ppc64.c: New File. * sysdeps/powerpc/powerpc64/multiarch/strstr.c: New File.
2015-07-16hppa/ia64: _dl_unmap: make it hiddenMike Frysinger4-4/+4
This symbol is only used by DL_UNMAP which in turn is only used by _dl_close_worker in dl-close.c, and _dl_close_worker itself is marked hidden as it is only used by the ldso. That means _dl_unmap should be marked hidden. Without this, the elf/check-localplt test fails.
2015-07-16hppa/ia64: _dl_symbol_address: add PLT bypass for rtldMike Frysinger2-0/+2
This symbol is defined in the ldso, and is used both there and libc.so. There is no hidden symbol for it though which leads to relocations in the ldso and the elf/check-localplt test failing. Add a hidden def for rtld to fix all of that. This function/file is only used by hppa & ia64, so no testing is needed for other arches.
