2009-08-25Handle AVX saving on x86-64 in interrupted smbol lookups.Ulrich Drepper
If a signal arrived during a symbol lookup and the signal handler also required a symbol lookup, the end of the lookup in the signal handler reset the flag whether restoring AVX/SSE registers is needed. Resetting means in this case that the tail part of the outer lookup code will try to restore the registers and this can fail miserably. We now restore to the previous value which makes nesting calls possible.

2009-08-10Fix check for PI mutex in x86-64 pthread_cond_signalAndreas Schwab
Register eax contains the syscall number, use a different one instead.
2009-08-08Optimize x86-64 version of sem_timedwait.Ulrich Drepper
2009-08-08Another minor optimization of x86-64 pthread_cond_wait.Ulrich Drepper
2009-08-07Small optimizations to cancellable x86-64 code.Ulrich Drepper
2009-08-04Optimize x86-64 syscall cancellation handling.Ulrich Drepper
The syscall wrappers had to save and restore the syscall parameter values and return value when calling the functions to enable/disable cancellation were called. Not anymore. The called functions are special and don't modify any unexpected registers.
2009-07-31Macro cleanup.Ulrich Drepper
Better definition of the *_NITSET macros.
2009-07-31Regenerated.Ulrich Drepper
2009-07-29Fix x86-64 TCB alignment for future processor versions.Ulrich Drepper
2009-07-29Preserve SSE registers in runtime relocations on x86-64.Ulrich Drepper
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.
2009-07-28Fix bookkeeping in mutex when using requeue_pi.Ulrich Drepper
2009-07-27pthread_mutex_unlock needs to use _rel semantics for atomic ops.Ulrich Drepper
2009-07-27Revert "Memory ordering in pthread_mutex_{,timed}lock."Ulrich Drepper
This reverts commit 7b7f43bed134db6a0da34282fffcbf0af10d4613.
2009-07-26Memory ordering in pthread_mutex_{,timed}lock.Ulrich Drepper
All commits should have happened before the mutex lock is taken. Therefore use the _rel variant of the cmpxchg atomic op.
2009-07-23Check for .cfi_{personality,lsda} on x86-64.Ulrich Drepper
We need this support in NPTL now to avoid the hand-coded tables.
2009-07-23Fix pthread_cond_timedwait error handling on old kernels.Ulrich Drepper
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.

2009-06-12Implement pthread_sigqueue.Ulrich Drepper
The kernel from 2.3.31 on supports the rt_tgsigqueueinfo syscall. Use it to implement the non-standard extension which, like sigqueue, can pass additional data to the receiving thread.
2009-06-11Fix futex syscall parameter for x86 absolute timeout waits.Bryan Kadzban
This affects only installations compiled for kernels older than 2.6.18.
2009-05-16libc-cancellation.c cleanup.Ulrich Drepper
The unrelated function __libc_cleanup_routine should not be in this file. Move it into its own file.
2009-05-16Unify source for async cancel handling.Ulrich Drepper
Unify all three places where we enable async cancellation for syscalls. Optimize a bit.
2009-05-16Rename nptl/init.c to nptl/nptl-init.c.Ulrich Drepper
Needed to allow overwriting architectures init.c in csu and nptl individually. Fixes BZ #9924.
2009-05-15ChangeLog entries incorrectly applied.Ulrich Drepper
2009-05-15Add missing export of fallocate64 on 32-bit platforms.Jakub Jelinek
Due to a pasto the fallocate64 interface, introduced in glibc 2.10, isn't exported for 32-bit Linux platforms. It is too late for this now so exported them for glibc 2.11.
2009-05-15Don't try to cleanup libselinux and libaudit.Jakub Jelinek
Because we are not shutting down the other threads first another thread might work on a query before the process shuts down. In this case the now uninitialized libselinux and libaudit might be used. Just don't free the resources. It's not necessary anyway because the process is about to terminate.
