Jakob Stoklund Olesen f86de96f78 Be more forgiving when calculating alias interference for physreg coalescing. ... It is OK for an alias live range to overlap if there is a copy to or from the physical register. CoalescerPair can work out if the copy is coalescable independently of the alias. This means that we can join with the actual destination interval instead of using the getOrigDstReg() hack. It is no longer necessary to merge clobber ranges into subregisters. llvm-svn: 107695		2010-07-06 20:31:51 +00:00
