2009-08-22Rvert accidental checkins.Ulrich Drepper5-545/+0
2009-08-22Add sigstack handling to Linux ____longjmp_chk on powerpc.Andreas Schwab5-0/+545
2009-08-11Add CFI directives to x86-64 pthread_rwlock_unlock.Ulrich Drepper1-2/+3
2009-08-10Add CFI directives to x86-64 pthread_rwlock_{rd,wr)lock.Ulrich Drepper2-2/+6
2009-08-10Fix check for PI mutex in x86-64 pthread_cond_signalAndreas Schwab1-3/+3
Register eax contains the syscall number, use a different one instead.
2009-08-08Optimize x86-64 version of sem_timedwait.Ulrich Drepper1-65/+145
2009-08-08Another minor optimization of x86-64 pthread_cond_wait.Ulrich Drepper1-15/+7
2009-08-07Small optimizations to cancellable x86-64 code.Ulrich Drepper4-61/+40
2009-08-04Optimize x86-64 syscall cancellation handling.Ulrich Drepper5-44/+179
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.
2009-07-31Regenerated.Ulrich Drepper1-8/+40
2009-07-29Fix x86-64 TCB alignment for future processor versions.Ulrich Drepper1-1/+6
2009-07-29Preserve SSE registers in runtime relocations on x86-64.Ulrich Drepper2-18/+56
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 Drepper5-20/+40
2009-07-23Check for .cfi_{personality,lsda} on x86-64.Ulrich Drepper2-0/+59
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 Drepper1-2/+2
2009-07-20Minor optimizations of last x86-64 condvar changes.Ulrich Drepper2-23/+16
2009-07-19Support requeueing for condvars using PI mutex. x86-64 only.Ulrich Drepper5-36/+168
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 Drepper1-0/+2
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.

2009-07-18Extend x86-64 pthread_cond_timedwait to use futex syscall with absolute timeout.Ulrich Drepper1-126/+292
2009-07-18Optimize x86-64 pthread_cond_timedwait.Ulrich Drepper1-144/+188
Instead of actively registering an unwind buffer we now use the exception handling functionality of the gcc runtime.

Instead of actively registering an unwind buffer we now use the exception handling functionality of the gcc runtime.

2009-06-12Implement pthread_sigqueue.Ulrich Drepper2-1/+90
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 Kadzban1-1/+1
This affects only installations compiled for kernels older than 2.6.18.
