2009-07-23Fix pthread_cond_timedwait error handling on old kernels.Ulrich Drepper
2009-07-23Avoid cpuid instructions in cache info discovery.Ulrich Drepper
When multiarch is enabled we have this information stored. Use it.
2009-07-23Add more cache descriptors for L3 caches on x86 and x86-64.Ulrich Drepper
The most recent AP 485 describes a few more cache descriptors for L3 caches with 24-way associativity.
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.
2009-07-23Avoid warnings in test cases.Ulrich Drepper
The posix/tst-rfc3484* test cases caused warnings in newer gccs because the unused but copied sin_zero part of sockaddr_in wasn't explicitly initialized.
2009-07-23Make include/unistd.h suitable for C++ test cases.Duncan Simpson
2009-07-23Preserve stack alignment in i386 makecontext.Ulrich Drepper
2009-07-23Minor optimization of unloading prevention patch.Ulrich Drepper
References to unique symbols from copy relocations can only come from executables which cannot be unloaded anyway. Optimize the code to set the unload flag a bit.
2009-07-23Fix comment.Ulrich Drepper
2009-07-23Some more fixes for the unique symbol handling.Ulrich Drepper
The hash value can be zero, so we need a different test for empty slots. And unify the way we prevent a DSO from being unloaded.
2009-07-23Handle unloading of DSO with a unique symbol definition.Ulrich Drepper
2009-07-21Add 2.11 news items.Ulrich Drepper
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.
2009-07-20Use correct index for _NL_CTYPE_NONASCII_CASE.Ulrich Drepper
2009-07-20Check generated locale for non-ASCII 8-bit characters with case conversion.Ulrich Drepper
If a locale does not have 8-bit characters with case conversion which are different from the ASCII conversion (±0x20) then we can perform some optimizations. These will follow later.
2009-07-20Minor optimizations of last x86-64 condvar changes.Ulrich Drepper
2009-07-19Support requeueing for condvars using PI mutex. x86-64 only.Ulrich Drepper
Add support for the new FUTEX_WAIT_REQUEUE_PI and FUTEX_CMP_REQUEUE_PI options of futex.
2009-07-19Make x86-64 pthread_cond_timedwait more robust.Ulrich Drepper
It just happens that __pthread_enable_asynccancel doesn't modify the $rdi register. But this isn't guaranteed. Hence we reload the register after the calls.

2009-07-18Optimize x86-64 pthread_cond_timedwait.Ulrich Drepper
Instead of actively registering an unwind buffer we now use the exception handling functionality of the gcc runtime.

2009-07-17Revert "Fix lock handling in memory hander of nscd."Ulrich Drepper
This reverts commit 137028b4d7e50f71906c1656c27079eac5a1d085. Conflicts: ChangeLog
2009-07-17Add missing BZ number in ChangeLog.Ulrich Drepper
2009-07-16Handle overly large answer buffers in resolver.Ulrich Drepper
In EDNS0 records the maximum result size is transmitted in a 16 bit value. Large buffer sizes were handled incorrectly by using only the low 16 bits. Fix this by limiting the size to 0xffff.
2009-07-16Fix lock handling in memory hander of nscd.Petr Baudis
The commit 20e498bd removes the pthread_mutex_rdlock() calls, but not the corresponding pthread_mutex_unlock() calls. Also, the database lock is never unlocked in one branch of the mempool_alloc() if. I think unreproducible random assert(dh->usable) crashes in prune_cache() were caused by this. But an easy way to make nscd threads hang with the broken locking was.
2009-07-16Use correct release semantic in list update.Andreas Schwab
nscd uses lockfree lists and we need to ensure the correct release semantics is used when adding to the list.
2009-07-16Fix race in corruption check.Ulrich Drepper
With atomic fastbins the checks performed can race with concurrent modifications of the arena. If we detect a problem re-do the test after getting the lock.
2009-07-16Use rel semantics of cas instead of acq semantics with full barrier before ↵Jakub Jelinek
it in _int_free The following patch fixes catomic_compare_and_exchange_*_rel definitions (which were never used and weren't correct) and uses catomic_compare_and_exchange_val_rel in _int_free. Comparing to the pre-2009-07-02 --enable-experimental-malloc state the generated code should be identical on all arches other than ppc/ppc64 and on ppc/ppc64 should use lwsync instead of isync barrier.
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.
