Jakob Stoklund Olesen a05b70241c Don't check liveness of unallocatable registers. ... This includes registers like EFLAGS and ST0-ST7. We don't check for liveness issues in the verifier and scavenger because registers will never be allocated from these classes. While in SSA form, we do care about the liveness of unallocatable unreserved registers. Liveness of EFLAGS and ST0 neds to be correct for MachineDCE and MachineSinking. llvm-svn: 136541		2011-07-29 23:36:21 +00:00
