2009-07-21Minor cleanups in x86-64 strstr.Ulrich Drepper
2009-07-20Better check for optimization in new x86-64 strstr/strcasestr.Ulrich Drepper
2009-07-20SSE4.2 strstr/strcasestr for x86-64.H.J. Lu
This patch implements SSE4.2 strstr/strcasestr, using Knuth-Morris-Pratt string searching algorithm.

2009-07-17Replace hand-coded unwind tables from x86-64 pthread_once.Ulrich Drepper
2009-07-16Remove warning and little optimization.Ulrich Drepper
The prototype for _dl_higher_prime_number was missing. While at it, the function is now marked with internal_function.
2009-07-16Optimize restoring of ymm registers on x86-64.Ulrich Drepper
The patch mainly reduces the code size but also avoids some jumps.
2009-07-16Fix up whitespaces in new memcmp for x86-64.Ulrich Drepper
2009-07-16memcmp implementation for x86-64 using SSE2.H.J. Lu
2009-07-15Fix thinko in AVX audit patch.Ulrich Drepper
Don't use AVX instructions too often.
2009-07-15Fix typo in last change.Ulrich Drepper
2009-07-15Secure AVX changes for auditing code.Ulrich Drepper
The original AVX patch used a function pointer to handle the difference between machines with and without AVX support. This is insecure. A well-placed memory exploit could lead to redirection of the execution. Using a variable and several tests is a bit slower but cannot be exploited in this way.
2009-07-10Add AVX support to ld.so auditing for x86-64.H.J. Lu
2009-07-10Fix comment in Linux's <sys/epoll.h>.Ulrich Drepper
2009-07-09Implement STB_GNU_UNIQUE handling.Ulrich Drepper
Some symbols have to be identified process-wide by their name. This is particularly important for some C++ features (e.g., class local static data and static variables in inline functions). This cannot completely be implemented with ELF functionality so far. The STB_GNU_UNIQUE binding helps by ensuring the dynamic linker will always use the same definition for all symbols with the same name and this binding.
2009-07-05Fix wrong PPC_FEATURE_* values.Andreas Schwab
Nothing uses these wrong values yet, but it fixes a warning due to conflicting definitions in <asm/cputable.h>.
2009-07-03Minor cleanups in recently added files.Ulrich Drepper
2009-07-03Align functions to 16-byte boundary.Ulrich Drepper
Some of the new multi-arch string functions for x86-64 were not aligned to 16 byte boundarie,s possibly creating unnecessary cache line misses and delays.
2009-07-03Add SSE4.2 support for strcspn, strpbrk, and strspn on x86-64.H.J. Lu
2009-07-02Fix handling of xmm6 in ld.so audit hooks on x86-64.H.J. Lu
2009-07-02Whitespace fixes in last patch.Ulrich Drepper
2009-07-02SSSE3 strcpy/stpcpy for x86-64H.J. Lu
This patch adds SSSE3 strcpy/stpcpy. I got up to 4X speed up on Core 2 and Core i7. I disabled it on Atom since SSSE3 version is slower for shorter (<64byte) data.

The ____longjmp_chk implementation didn't load from memory the right way.

2009-06-16Extend pt_chown to drop privileges.Ulrich Drepper
If libcap is available, use it to drop privileges in pt_chown before starting the work to change the permissions and ownership of the slave device.
2009-06-16Fix x86-64 memchr for large lengths.Jakub Jelinek
2009-06-16Fix incorrect use of cmpldi in 32-bit PPC code.Ryan S. Arnold
The 32-bit PowerPC POWER6 memcpy uses the cmpldi insn when it should use a cmplwi. BZ #10107

2009-06-15Fix permission of slave device on devpts if necessary.Ulrich Drepper
If devptr is misconfigured the slave device permission after grantpt might not be 0620. BZ #10166
2009-06-15Preserve message printed before abort.Ulrich Drepper
The terminal output etc is not visible in a core file. The new libc-internal variable __abort_msg will point to a string with the message which has been printed before the abort in case abort is called from inside libc. BZ #10217
2009-06-15libc part of prelink IFUNC support.Jakub Jelinek
The dl-lookup.c changes are needed for prelink (support in prelink checked into SVN, tested for both i?86 and x86-64), dl-irel.h just something I discovered by code inspection.
2009-06-14Fix warnings when using <sys/select.h>.Ulrich Drepper
gcc 4.4 is more picky. And the x86-64 version of <bits/select.h> contained a now unnecessary asm optimization. Remove it.

2009-06-05Add SSE4.2 optimized rawmemchr implementation for x86-64.Ulrich Drepper
2009-06-05Forgot some more cleanups for the SSE4.2 strlen on x86-64.Ulrich Drepper
2009-06-05Add missing cleanups from SSE4.2 x86-64 strlen.Ulrich Drepper
2009-06-05Optimize x86-64 strlen for SSE4.2.Ulrich Drepper
The SSE4.2 implementation is used in the DSO only. The patch also adds some infrastructure to be used in similar code later one.
