2009-08-25Handle AVX saving on x86-64 in interrupted smbol lookups.Ulrich Drepper1-2/+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.
2009-08-04Optimize x86-64 syscall cancellation handling.Ulrich Drepper1-0/+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.

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.
