2014-05-12Clean up kernel version conditionals for pre-2.6.32 kernels.Joseph Myers8-162/+126
This patch does some initial cleanup, following the move to 2.6.32 minimum kernel version, by removing __LINUX_KERNEL_VERSION conditionals that are now always-true or always-false. In the case of __ASSUME_ARG_MAX_STACK_BASED, where the conditional used a kernel version that was itself in a macro, the associated sysconf.c code is also cleaned up and __ASSUME_ARG_MAX_STACK_BASED removed completely. Tested x86_64 that disassembly of installed shared libraries is unchanged by the patch. * sysdeps/unix/sysv/linux/kernel-features.h [__s390__] (__ASSUME_UTIMES): Do not condition on kernel version.

2014-05-09Fix elf/tst-tls9-static buildAdhemerval Zanella2-2/+7
This patch fixes the tst-tlsmod[5/6].so build in system that uses -Wl,--as-needed as default in linker option. Without this option the testing shared library that does not have libc.so in DT_NEEDED and the tst-tls9-static fails in architecture that use the ./sysdeps/unix/sysv/linux/<arch>/dl-static.c trick.
2014-05-09Silence a missing-noreturn warning for _Unwind_Resume.Roland McGrath2-5/+11
2014-05-09Include SSE state in i386 fenv_t (bug 16064).Joseph Myers7-19/+204
This patch fixes bug 16064, i386 fenv_t not including SSE state, using the technique suggested there of storing the state in the existing __eip field of fenv_t to avoid needing to increase the size of fenv_t and add new symbol versions. The included testcase, which previously failed for i386 (but passed for x86_64), illustrates how the previous state was buggy. This patch causes the SSE state to be included *to the extent it is on x86_64*. Where some state should logically be included but isn't for x86_64 (see bug 16068), this patch does not cause it to be included for i386 either. The idea is that any patch fixing that bug should fix it for both x86_64 and i386 at once. Tested i386 and x86_64. (I haven't tested the case of a CPU without SSE2 disabling the test.) [BZ #16064] * sysdeps/i386/fpu/fegetenv.c: Include <unistd.h>, <ldsodefs.h> and <dl-procinfo.h>. (__fegetenv): Save SSE state in envp->__eip if supported. * sysdeps/i386/fpu/feholdexcpt.c (feholdexcept): Save SSE state in envp->__eip if supported. * sysdeps/i386/fpu/fesetenv.c: Include <unistd.h>, <ldsodefs.h> and <dl-procinfo.h>. (__fesetenv): Always set __eip, __cs_selector, __opcode, __data_offset and __data_selector in environment to 0. Set SSE state if supported. * sysdeps/x86/fpu/Makefile [$(subdir) = math] (tests): Add test-fenv-sse. [$(subdir) = math] (CFLAGS-test-fenv-sse.c): Add -msse2 -mfpmath=sse. * sysdeps/x86/fpu/test-fenv-sse.c: New file.
2014-05-09ARM: Allow auto-detection of linker relro featureWill Newton3-0/+22
Set values for libc_commonpagesize and libc_relro_required for the ARM port to enable relro by default and suppress a warning at configure time. ChangeLog: 2014-05-09 Will Newton <will.newton@linaro.org> * sysdeps/arm/preconfigure.ac: Set libc_commonpagesize and libc_relro_required for ARM. * sysdeps/arm/preconfigure: Regenerate.
2014-05-09S/390: Port of lock elision to System/zDominik Vogt21-2/+693
Added support for TX lock elision of pthread mutexes on s390 and s390x. This may improve lock scaling of existing programs on TX capable systems. The lock elision code is only built with --enable-lock-elision=yes and then requires a GCC version supporting the TX builtins. With lock elision default mutexes are elided via __builtin_tbegin, if the cpu supports transactions. By default lock elision is not enabled and the elision code is not built.
2014-05-09ARM: Add optimized ARMv7 strcmp implementationWill Newton3-0/+499
Add an optimized implementation of strcmp for ARMv7-A cores. This implementation is significantly faster than the current generic C implementation, particularly for strings of 16 bytes and longer. Tested with the glibc string tests for arm-linux-gnueabihf and armeb-linux-gnueabihf. The code was written by ARM, who have agreed to assign the copyright to the FSF for integration into glibc. ChangeLog: 2014-05-09 Will Newton <will.newton@linaro.org> * sysdeps/arm/armv7/strcmp.S: New file. * NEWS: Mention addition of ARMv7 optimized strcmp.

2014-05-06PowerPC: strncpy/stpncpy optimization for PPC64/POWER7Vidya Ranganathan11-1/+610
The optimization is achieved by following techniques: > data alignment [gain from aligned memory access on read/write] > POWER7 gains performance with loop unrolling/unwinding [gain by reduction of branch penalty]. > zero padding done by calling optimized memset
2014-05-06Don't use catomic functions in mcount (BZ #16912)Andreas Schwab3-3/+10
mcount cannot use catomic functions since it is called by __libc_start_main before TLS is set up. This reverts the change made by commit 8099361.

2014-05-05PowerPC: ifunc improvement for internal callsAdhemerval Zanella8-26/+64
This patch changes de default symbol redirection for internal call of memcpy, memset, memchr, and strlen to the IFUNC resolved ones. The performance improvement is noticeable in algorithms that uses these symbols extensible, like the regex functions.
2014-05-03Revert incorrect removal of the XDR currency from locale/iso-4217.defAdam Conrad2-0/+5
In 7447ccd98ee3944a95247ae23284dfac1de6c2aa, the XDR currency was removed from locale/iso-4217.def, despite the fact that it's both still a part of the standard, according to the official table: http://www.currency-iso.org/dam/downloads/table_a1.xml ... and, more importantly, is referenced from localedata/i18n, so any quick-and-dirty locale definition that uses "copy i18n" for LC_MONETARY wouldn't work anymore.

Define FEATURE_INDEX_1 and FEATURE_INDEX_MAX as macros for use by both assembly and C code. This fixes the -Wundef error for cases where FEATURE_INDEX_1 was not defined but used the correct value of 0 for an undefined macro.

2014-05-01ARM: Remove lowlevellock.cWill Newton2-132/+6
lowlevellock.c for arm differs from the generic lowlevellock.c only in insignificant ways, so can be removed. Happily, this fixes BZ 15119 (unnecessary busy loop in __lll_timedlock_wait on arm). The notable differences between the arm and generic implementations are: 1) arm __lll_timedlock_wait has a fast path out if futex has been set to 0 between since the function was called. This seems unlikely to happen very often, so it seems at worst harmless to lose this fast path. 2) Some function in arm's lowlevellock.c set futex to 2 if it was 1. The generic version always sets the futex to 2. As futex can only be 0, 1 or 2 on entry into these functions, the behaviour is equivalent. (If the futex manages to be 0 on entry then we've just lost another unlikely fast path out.) There are no test suite regressions. Note that hppa and sparc also have their own lowlevellock.c. I believe hppa can also be removed, so I'll send a separate patch for that shortly. sparc's seems to be genuinely needed as it uses a different locking structure. Also note that the analysis at https://sourceware.org/ml/libc-ports/2013-02/msg00021.html indicates a further locking performance bug to fix - I've got a partial patch for that which I can submit once I've finished testing. 2014-05-01 Bernard Ogden <bernie.ogden@linaro.org> [BZ #15119] * sysdeps/unix/sysv/linux/arm/nptl/lowlevellock.c: Remove file.
