2014-07-10setlocale: Use the heap for the copy of the locale argumentFlorian Weimer2-2/+17
This avoids alloca calls with potentially large arguments.
2014-07-10Sync up error.c with gnulibSiddhesh Poyarekar2-10/+103
Summary of changes: - Use of !_LIBC instead of HAVE_CONFIG_H - Code changes in [!_LIBC] that don't affect us - Minor formatting changes - Use __builtin_expect in shared code - Define some macros in [_LIBC] that are used in gnulib but never defined in glibc - Flip macro check for STRERROR_R_CHAR_P so that it does not throw a warning
2014-07-10Fix -Wundef warning for HAVE_LOCALTIME_RSiddhesh Poyarekar2-0/+3
Define it to 0. There is a gnulib copy for this, but it is out of sync with our copy.
2014-07-10Fix Wundef warning for HAVE_STRFTIMESiddhesh Poyarekar2-0/+3
Define it to 0
2014-07-10Fix -Wundef warning for HAVE_SYS_PARAM_HSiddhesh Poyarekar2-3/+3
Include sys/param.h unconditionally
2014-07-10Fix -Wundef warning for HAVE_OBSTACKSiddhesh Poyarekar2-5/+3
Remove the HAVE_OBSTACK macro check and include obstack check in include path order since we don't have a copy of obstack.h in the current directory.
2014-07-10Fix crash when system has no ipv6 address [BZ #17125]Siddhesh Poyarekar3-2/+13
Here's an updated patch to fix the crash in bug-ga2 when the system has no configured ipv6 address. I have taken a different approach of using libc_freeres_fn instead of the libc_freeres_ptr since the former gives better control over what is freed; we need that since cache may or may not be allocated using malloc. Verified that bug-ga2 works correctly in both cases and does not have memory leaks in either of them.

2014-07-09Fix -Wundef warnings for SHAREDWill Newton6-5/+13
The definition of SHARED is tested with #ifdef pretty much everywhere apart from these few places. The tlsdesc.c code seems to be copy and pasted to a few architectures and there is one instance in the hppa startup code. ChangeLog: 2014-07-09 Will Newton <will.newton@linaro.org> * sysdeps/aarch64/tlsdesc.c (_dl_unmap): Test SHARED with #ifdef. * sysdeps/arm/tlsdesc.c (_dl_unmap): Likewise. * sysdeps/i386/tlsdesc.c (_dl_unmap): Likewise. * sysdeps/x86_64/tlsdesc.c (_dl_unmap): Likewise. * sysdeps/hppa/start.S (_start): Likewise.
2014-07-09Fix -Wmaybe-uninitialized warning in xdr.cSiddhesh Poyarekar2-1/+3
While we're at fixing build warnings, here's one unnecessary warning that can be fixed fairly easily. The SIZE variable is never actually use uninitialized, but the compiler cannot make that out and thinks (correctly) that there is a potential for accessing SIZE without initializing it. Make this safe by initializing SIZE to 0. Tested on x86_64.
2014-07-09Fix Wundef warning for __cplusplusSiddhesh Poyarekar2-1/+6
All current uses of the __cplusplus macro only check if it is defined or not. Fix this #if to use $ifdef like the rest of the code.
2014-07-08Check value at resplen2 if it is not NULLSiddhesh Poyarekar2-4/+8
There was a typo in the previous patch due to which resplen2 was checked for non-zero instead of the value at resplen2. Fix that and improve the condition by checking resplen2 for non-NULL (instead of answerp2) and also adding the check in a third place.
2014-07-08Fix Wundef warning for ELF_MACHINE_NO_REL on i386Siddhesh Poyarekar2-0/+5
2014-07-08PowerPC: Cleanup powerpc memmoveAdhemerval Zanella6-25/+15
Now that MEMCPY_OK_FOR_FWD_MEMMOVE should be define on memcopy.h there is no need to specialized powerpc memmove implementation. This patch moves the define set to powerpc memcopy and cleanup its definition on powerpc code.
2014-07-08PowerPC: Fix compiler warningsAdhemerval Zanella4-3/+12
This patch fixes some compiler due trailing data in #undef directives and due missing prototypes.
2014-07-08PowerPC: Add ifunc tests for memmoveAdhemerval Zanella2-0/+11
This patch add the missing ifunc tests definition for memmove ppc32 optimization patch (commit 07aedd7).
2014-07-08Fix Wundef warning with SHOJI_IS_RIGHTSiddhesh Poyarekar18-468/+37
The macro is not defined anywhere, so it looks like we're convinced that Shoji is wrong :)
2014-07-07PowerPC: Align power7 memcpy using VSX to quadwordAdhemerval Zanella3-20/+10
This patch changes power7 memcpy to use VSX instructions only when memory is aligned to quardword. It is to avoid unaligned kernel traps on non-cacheable memory (for instance, memory-mapped I/O).
2014-07-07PowerPC: optimized memmove for POWER7/PPC32Adhemerval Zanella5-1/+109
This patch adds a optimized memmove for power7 by using the optimized power7 memcpy for forward copying.
2014-07-07PowerPC: optimized memmove for POWER7/PPC64Adhemerval Zanella11-2/+1037
This patch adds an optimized memmove optimization for POWER7/powerpc64. Basically the idea is to use the memcpy for POWER7 on non-overlapped memory regions and a optimized backward memcpy for memory regions that overlap (similar to the idea of string/memmove.c). The backward memcpy algorithm used is similar the one use for memcpy for POWER7, with adjustments done for alignment. The difference is memory is always aligned to 16 bytes before using VSX/altivec instructions.
2014-07-07PowerPC: memmove default implementation cleanupAdhemerval Zanella2-97/+5
This patch removes the powerpc specific logic in memmove and instead include default implementation with MEMCPY_OK_FOR_FWD_MEMMOVE defined. This lead in a increase performance, since the constraints to use memcpy in powerpc code are too restrictive and memcpy can be used for any forward memmove.
2014-07-07PowerPC: Guard CALL_ELF check for ppc64 only in link.hAdhemerval Zanella2-2/+9
This patch fixes powerpc32 undef compiler warnings for _CALL_ELF, since it is defined only for powerpc64.

2014-07-04string/memchr.c: Merge from gnulibWill Newton2-139/+101
Merge most of the gnulib implementation of memchr. The changes that remain are: - copyright header - bp-sym.h removed - reg_char removed - allow MEMCHR to be redefined - non-conforming whitespace changes The merged code fixes a number of -Wundef warnings and also introduces an optimized algorithm. I haven't detected any performance difference in the new code which I believe is down to the quite specific circumstances required to hit it. However the new code is approximately half the size of the old code on AArch64 (which uses generic memchr). ChangeLog: 2014-07-04 Will Newton <will.newton@linaro.org> * string/memchr.c: Merge from gnulib. [_LIBC]: Remove conditionals. (__ptr_t): Remove define. (LONG_MAX_32_BITS): Likewise. (LONG_MAX): Likewise. (MEMCHR): Use ANSI prototype and optimize algorithm.
2014-07-04ARM: Define ELF_MACHINE_NO_RELWill Newton2-0/+5
Fix a -Wundef warning on ARM. ChangeLog: 2014-07-04 Will Newton <will.newton@linaro.org> * sysdeps/arm/dl-machine.h (ELF_MACHINE_NO_REL): Define.

2014-07-03Restore subdir conditional for tst-timer dependency.Siddhesh Poyarekar2-0/+9
2014-07-03alpha: Remove nearbyint and nearbyintf implementationsRichard Henderson3-72/+5
The original implementation was written for EV5, which does not record inexact in the status register for /SU (but no /I) insns. But EV6 does record the inexact status; the lack of /I simply means that the exception is suppressed. Adding feholdexcept becomes the bulk of the overhead, so we might as well use the default implementation.
2014-07-03alpha: Implement math_opt_barrier and math_force_evalRichard Henderson2-0/+9
2014-07-03alpha: Fix lround implementationsRichard Henderson3-8/+11
Use chopped rounding to add 0.5.
2014-07-03alpha: Remove round and roundf implementationsRichard Henderson3-91/+3
Two bugs in these implementations: First is that the add of 0.5 was not done in chopped rounding mode (easily fixable). Second is that the method generates incorrect inexact exceptions for small integral values (not easily fixable).
