* Properly restore AVX registers on x86-64.H.J. Lu2009-07-292-10/+14
| | | | | tst-audit4 and tst-audit5 fail under AVX emulator due to je instead of jne. This patch fixes them.
* Preserve SSE registers in runtime relocations on x86-64.Ulrich Drepper2009-07-2910-21/+188
| | | | | | | | | | SSE registers are used for passing parameters and must be preserved in runtime relocations. This is inside ld.so enforced through the tests in tst-xmmymm.sh. But the malloc routines used after startup come from libc.so and can be arbitrarily complex. It's overkill to save the SSE registers all the time because of that. These calls are rare. Instead we save them on demand. The new infrastructure put in place in this patch makes this possible and efficient.

* Refine testing for xmm/ymm register use in x86-64 ld.so.Ulrich Drepper2009-07-276-12/+86
| | | | | | | | | The test now takes the callgraph into account. Only code called during runtime relocation is affected by the limitation. We now determine the affected object files as closely as possible from the outside. This allowed to remove some the specializations for some of the string functions as they are only used in other code paths.
* Break out _dl_scope_free into its own file.Ulrich Drepper2009-07-273-36/+59
| | | | | This reduces the coarse static callgraph that can be discovered by looking at the object files.
* Define and implement RES_USE_DNSSEC option in resolver.Adam Tkac2009-07-275-5/+26
|
* Fix STB_GNU_UNIQUE handling for > 30 unique symbols.Jakub Jelinek2009-07-272-2/+9
| | | | | | | | | | | | | There were several issues when the initial 31 entries hashtab filled up. size * 3 <= tab->n_elements is always false, table can't have more elements than its size. I assume from libiberty/hashtab.c this meant to be check for 3/4 full. Even after fixing that, _dl_higher_prime_number (31) apparently returns 31, only _dl_higher_prime_number (32) returns 61. And, size variable wasn't updated during reallocation, which means during reallocation the insertion of the new entry was done into a wrong spot. All this lead to a hang in ld.so, because a search with n_elements 31 size 31 wouldn't ever terminate.
* No need for special strcmp for rtld.Ulrich Drepper2009-07-272-29/+0
|
* Make sure no code in ld.so uses xmm/ymm registers on x86-64.Ulrich Drepper2009-07-2611-0/+498
| | | | | | | | | | This patch introduces a test to make sure no function modifies the xmm/ymm registers. With the exception of the auditing functions. The test is probably too pessimistic. All code linked into ld.so is checked. Perhaps at some point the callgraph starting from _dl_fixup and _dl_profile_fixup is checked and we can start using faster SSE-using functions in parts of ld.so.
* Add missing ChangeLog entry for last checkin.Ulrich Drepper2009-07-261-0/+20

* Add SSE2 support to str{,n}cmp for x86-64.H.J. Lu2009-07-265-267/+2055
|
* Memory ordering in pthread_mutex_{,timed}lock.Ulrich Drepper2009-07-263-12/+19
| | | | | All commits should have happened before the mutex lock is taken. Therefore use the _rel variant of the cmpxchg atomic op.
* Compatibility of signalfd/eventfd with older kernels.Ulrich Drepper2009-07-264-6/+34
|
* Handle SERVFAIL, NOTIMP, REFUSED replies from DNS server better.Ulrich Drepper2009-07-262-5/+5
| | | | | When doing IPv4+6 lookups we have to pass up the error record from send_dg.
* Define NT_GNU_GOLD_VERSION.Ulrich Drepper2009-07-262-0/+7
|
* Some some optimizations for x86-64 strcmp.H.J. Lu2009-07-252-9/+7
|
* Handle missing NSS modules and those without callbacks.Ulrich Drepper2009-07-252-0/+6
| | | | | getaddrinfo didn't update the status variable in that round of the loop if no callback was used.
* Optimize x86-64 SSE4.2 strcmp.Ulrich Drepper2009-07-252-0/+10
| | | | | The file contained some code which was never used. Don't compile it in.
* Don't automatically use /lib/modules/* headers.Ulrich Drepper2009-07-243-24/+6
| | | | | Ever since the /usr/include/linux headers got cleaned up this isn't necessary. Meanwhile everybody should have these cleanups.
* More white space fixes.Ulrich Drepper2009-07-241-4/+4

* White space fixes in last checkin.Ulrich Drepper2009-07-242-7/+7

|
* Check for .cfi_{personality,lsda} on x86-64.Ulrich Drepper2009-07-233-0/+61
| | | | We need this support in NPTL now to avoid the hand-coded tables.
* Fix pthread_cond_timedwait error handling on old kernels.Ulrich Drepper2009-07-232-2/+7
|
* Avoid cpuid instructions in cache info discovery.Ulrich Drepper2009-07-232-19/+35
| | | | When multiarch is enabled we have this information stored. Use it.
* Add more cache descriptors for L3 caches on x86 and x86-64.Ulrich Drepper2009-07-233-0/+10
| | | | | The most recent AP 485 describes a few more cache descriptors for L3 caches with 24-way associativity.
* Perform test for Arom x86-64 in central place and handle it.Ulrich Drepper2009-07-233-11/+15
| | | | | | | 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.
* Avoid warnings in test cases.Ulrich Drepper2009-07-234-0/+11
| | | | | | 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.
* Make include/unistd.h suitable for C++ test cases.Duncan Simpson2009-07-232-0/+8
|
* Preserve stack alignment in i386 makecontext.Ulrich Drepper2009-07-232-6/+7
|
* Minor optimization of unloading prevention patch.Ulrich Drepper2009-07-231-5/+5
| | | | | | 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.
* Fix comment.Ulrich Drepper2009-07-231-1/+1
|
* Some more fixes for the unique symbol handling.Ulrich Drepper2009-07-232-5/+7
| | | | | 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.

|
* SSE4.2 strstr/strcasestr for x86-64.H.J. Lu2009-07-208-5/+551
| | | | | This patch implements SSE4.2 strstr/strcasestr, using Knuth-Morris-Pratt string searching algorithm.
* Use correct index for _NL_CTYPE_NONASCII_CASE.Ulrich Drepper2009-07-202-5/+5
|
* Check generated locale for non-ASCII 8-bit characters with case conversion.Ulrich Drepper2009-07-205-4/+47
| | | | | | 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.
* Minor optimizations of last x86-64 condvar changes.Ulrich Drepper2009-07-203-23/+22
|

* Make x86-64 pthread_cond_timedwait more robust.Ulrich Drepper2009-07-192-0/+7
| | | | | | 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.
