01b597da40 Check for .cfi_{personality,lsda} on x86-64. 
We need this support in NPTL now to avoid the hand-coded tables.

f1adf1f490 Fix pthread_cond_timedwait error handling on old kernels. 2009-07-23 16:39:06 -07:00

c3db953c16 Minor optimizations of last x86-64 condvar changes. 2009-07-20 08:39:47 -07:00
Ulrich Drepper
42e69bcf11 Support requeueing for condvars using PI mutex. x86-64 only. 
Add support for the new FUTEX_WAIT_REQUEUE_PI and FUTEX_CMP_REQUEUE_PI
options of futex.

515a8908ce Make x86-64 pthread_cond_timedwait more robust. 
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.

92618c954f Optimize x86-64 pthread_cond_timedwait. 
Instead of actively registering an unwind buffer we now use the
exception handling functionality of the gcc runtime.

bfdb73e145 Implement pthread_sigqueue. 
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.
