586fa886ad Fix x86-64 TCB alignment for future processor versions. 2009-07-29 09:01:04 -07:00
Ulrich Drepper
b48a267b8f Preserve SSE registers in runtime relocations on x86-64. 
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.

b0948ffdcb Fix bookkeeping in mutex when using requeue_pi. 2009-07-28 09:40:39 -07:00
Ulrich Drepper
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
Ulrich Drepper
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.
