* Handle AVX saving on x86-64 in interrupted smbol lookups.Ulrich Drepper2009-08-251-2/+8
| | | | | | | | | 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.
* Optimize x86-64 syscall cancellation handling.Ulrich Drepper2009-08-041-0/+10
| | | | | | | 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.

* Preserve SSE registers in runtime relocations on x86-64.Ulrich Drepper2009-07-292-18/+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.
* Check for .cfi_{personality,lsda} on x86-64.Ulrich Drepper2009-07-232-0/+59
| | | | We need this support in NPTL now to avoid the hand-coded tables.
