Jakob Stoklund Olesen 5b8f476037 Correctly deal with identity copies in RegisterCoalescer. ... Now that the coalescer keeps live intervals and machine code in sync at all times, it needs to deal with identity copies differently. When merging two virtual registers, all identity copies are removed right away. This means that other identity copies must come from somewhere else, and they are going to have a value number. Deal with such copies by merging the value numbers before erasing the copy instruction. Otherwise, we leave dangling value numbers in the live interval. This fixes PR12927. llvm-svn: 157340		2012-05-23 20:21:06 +00:00
