Bob Wilson 013dfaa93a Stabilize the order of live intervals in the priority_queue used by the ... linear scan reg alloc. This fixes a problem I ran into where extracting a function from a larger file caused the generated code to change (masking the problem I was trying to debug) because the allocator behaved differently. This changes the results for two X86 regression checks. stack-color-with-reg is improved, with one less instruction, but pr3495 is worse, with one more copy. As far as I can tell, these tests were just getting lucky or unlucky, so I've changed the expected results. llvm-svn: 81060		2009-09-05 01:19:16 +00:00
