Evan Cheng d158fba3e4 Add a peephole optimization to optimize pairs of bitcasts. e.g. ... v2 = bitcast v1 ... v3 = bitcast v2 ... = v3 => v2 = bitcast v1 ... = v1 if v1 and v3 are of in the same register class. bitcast between i32 and fp (and others) are often not nops since they are in different register classes. These bitcast instructions are often left because they are in different basic blocks and cannot be eliminated by dag combine. rdar://9104514 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127668 91177308-0d34-0410-b5e6-96231b3b80d8		2011-03-15 05:13:13 +00:00
