2009-07-23Perform test for Arom x86-64 in central place and handle it.Ulrich Drepper
There will be more than one function which, in multiarch mode, wants to use SSSE3. We should not test in each of them for Atoms with slow SSSE3. Instead, disable the SSSE3 bit in the startup code for such machines.

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

2009-07-02SSSE3 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.

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.
