2013-03-12Include atomic.h in generic lowlevellock.c.Carlos O'Donell2-1/+5
2013-03-13Update zic from tzcode 2013b.Joseph Myers2-2/+8
2013-03-12Remove mention of i386-pc-linux-gnu.Carlos O'Donell3-7/+18
The GNU C Library does not support building for i386 therefore we remove mention of this configuration from the INSTALL file.
2013-03-12ARM: Make armv6t2 memchr implementation usable without Thumb.Roland McGrath2-2/+26
2013-03-12ARM: Change register allocation in armv6t2 memchr implementation.Roland McGrath2-15/+20

2013-03-12ia64: fix set-but-unused warnings with syscallsMike Frysinger2-2/+11
These macros often set up a variable that later macros sometimes do not use. Add unused attribute to avoid that. Similarly, the ia64 code tends to check the err field rather than the val (which is opposite of most arches) leading to the same kind of warning. Replace this with a dummy reference.

2013-03-12ia64: fix strict aliasing warnings with libm errorMike Frysinger2-58/+81
The current code declares double constants by using a char buffer and then casting the pointer to a different type. This makes the aliasing logic unhappy. Change it to use a union instead to avoid that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-03-12ia64: fix strict aliasing warnings with func descriptorsMike Frysinger5-13/+34
Function pointers on ia64 are like parisc -- they're plabels. While the parisc port enjoys a gcc builtin for extracting the address here, ia64 has no such luck. Casting & dereferencing in one go triggers a strict aliasing warning. Use a union to fix that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-03-11Add comments about ARM configure -fno-unwind-tables handling.Joseph Myers5-0/+21

2013-03-11Remove extra pthread_atfork compat symbolsAndreas Schwab14-8/+38
2013-03-10ia64: makecontext: fix signed warningsMike Frysinger2-2/+7
The ia64_rse_is_rnat_slot func expects an unsigned pointer, but we're passing in a signed pointer. The signness doesn't matter here, so convert it to unsigned. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-03-10ia64: fix NEED_DL_SYSINFO_DSO conditionalsMike Frysinger2-23/+13
The recent change to clean up these defines missed the ia64 logic. Update it accordingly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2013-03-08PowerPC: unify math_ldbl.h implementationsAdhemerval Zanella5-168/+34
This patch removes redudant definition from PowerPC specific math_ldbl, using the definitions from ieee754 math_ldbl.h.
2013-03-08Consolidate copies of mp code in powerpcSiddhesh Poyarekar7-221/+15
Retain a single copy of the mp code in power4 instead of the two identical copies in powerpc32 and powerpc64.
2013-03-07arm: Implement armv6 optimized string routinesRichard Henderson8-0/+707
The strcpy and strchr (and related) functions are four times faster than the byte-by-byte default versions. The strlen function is twice as fast for long strings and 50% faster for short strings over the armv4 version.
2013-03-07AARCH64: Use <bits/mman-linux.h>Andreas Jaeger2-73/+8
* sysdeps/unix/sysv/linux/aarch64/bits/mman.h: Remove all defines provided by bits/mman-linux.h and include <bits/mman-linux.h>.
2013-03-07Install <bits/mman-linux.h>Andreas Jaeger2-1/+7
* sysdeps/unix/sysv/linux/Makefile (sysdep_headers): Add bits/mman-linux.h.
2013-03-07Merge powerpc slowexp.c into generic codeSiddhesh Poyarekar6-133/+21
2013-03-07Merge powerpc slowpow.c into generic codeSiddhesh Poyarekar6-186/+29

2013-03-07Use generic mpa.c code for everything except __mul and __sqrSiddhesh Poyarekar4-1256/+19
2013-03-07Remove PIPE_BUF Linux-specific codeSiddhesh Poyarekar6-28/+190
Fixes BZ #12723 The variable pipe buffer size does nothing to the value of PIPE_BUF, since the number of bytes that are atomically written is still PIPE_BUF on Linux.
2013-03-06Revert " * sysdeps/x86_64/strlen.S: Replace with new SSE2 based implementation"Ondrej Bilka13-763/+1306
This reverts commit b79188d71716b6286866e06add976fe84100595e.
2013-03-06 * sysdeps/x86_64/strlen.S: Replace with new SSE2 based implementationOndrej Bilka13-1306/+763
which is faster on all x86_64 architectures. Tested on AMD, Intel Nehalem, SNB, IVB.
2013-03-06T_REMOVEDIR and AT_EACCESS have the same value.Patsy Franklin2-0/+10
Add comments to fcntl.h explaining why AT_REMOVEDIR and AT_EACCESS can have the same value.
2013-03-06Use <bits/mman-linux.h> for MIPSAndreas Jaeger4-73/+17
* sysdeps/unix/sysv/linux/bits/mman-linux.h (MAP_ANONYMOUS): Allow definition via __MAP_ANONYMOUS. * sysdeps/unix/sysv/linux/mips/bits/mman.h: Remove all defines provided by bits/mman-linux.h and include <bits/mman-linux.h>. (__MAP_ANONYMOUS): Define.
2013-03-06arm: Add optimized add_n and sub_nRichard Henderson3-0/+88
Written from scratch rather than copied from GMP, due to LGPL 2.1 vs GPL 3, but tested with the GMP testsuite. This is 250% faster than the generic code as measured on Cortex-A15, and the same speed as GMP on the same core, and probably everywhere.
2013-03-06arm: Add optimized submul_1Richard Henderson2-0/+69
Written from scratch rather than copied from GMP, due to LGPL 2.1 vs GPL 3, but tested with the GMP testsuite. This is 50% faster than the generic code as measured on Cortex-A15. It is 25% slower than the current GMP routine on the same core.
2013-03-06arm: Add optimized addmul_1Richard Henderson2-0/+68
Written from scratch rather than copied from GMP, due to LGPL 2.1 vs GPL 3, but tested with the GMP testsuite. This is 25% faster than the generic code as measured on Cortex-A15, and the same speed as GMP on the same core. It's probably slower than GMP on the A8 and A9 cores though.
2013-03-06arm: Add optimized ffs for armv6t2Richard Henderson3-0/+88
2013-03-06arm: Implement hard-tp for GET_TLSRichard Henderson4-11/+30
2013-03-06arm: Tidy architecture selectionRichard Henderson3-8/+45
2013-03-06arm: Unless arm4t, pop return address directly into pcRichard Henderson3-5/+14
2013-03-06arm: Commonize BX conditionalsRichard Henderson4-30/+21
Add BLX macro in addition and use it where appropriate.
2013-03-06arm: Delete LOADREGS macroRichard Henderson3-5/+4
There was only one user. It's "condition" argument was used for "ia" rather than an actual condition. The apcs26 syntax is almost certainly not needed, given current binutils requirements.
