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.
2009-07-28Fix bookkeeping in mutex when using requeue_pi.Ulrich Drepper
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.
2009-07-19Extend x86-64 __lll_robust_timedlock_wait to use futex syscall with absolute ↵Ulrich Drepper
timeout.
2009-07-18Extend x86-64 pthread_rwlock_timedrdlock to use futex syscall with absolute ↵Ulrich Drepper
timeout.
2009-07-18Pretty printing last change.Ulrich Drepper
2009-07-18Extend x86-64 pthread_rwlock_timedwrlock to use futex syscall with absolute ↵Ulrich Drepper
timeout.
2009-07-18Remove leftover cfi.Ulrich Drepper
2009-07-18Extend x86-64 pthread_cond_timedwait to use futex syscall with absolute timeout.Ulrich Drepper
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.

2009-07-17Extend x86-64 sem_timedwait to use futex syscall with absolute timeout.Ulrich Drepper
2009-07-17Consistently use symbolic constants.Ulrich Drepper
2009-07-17Replace hand-coded unwind tables from x86-64 sem_timedwait.Ulrich Drepper
2009-07-17Optimize x86-64 sem_wait for uncontested semaphore.Ulrich Drepper
2009-07-17Replace hand-coded unwind tables from x86-64 sem_wait.Ulrich Drepper
2009-07-17Replace hand-coded unwind tables from x86-64 pthread_once.Ulrich Drepper
2009-07-17Replace hand-coded unwind tables from x86-64 pthread_cond_wait.Ulrich Drepper
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.
