David Mosberger-Tang 30325d1771 [IA64] speed up syscall path a bit more ... Recently I noticed that clearing ar.ssd/ar.csd right before srlz.d is causing significant stalling in the syscall path. The patch below fixes that by moving the register-writes after srlz.d. On a Madison, this drops break-based getpid() from 241 to 226 cycles (-15 cycles).
