Manman Ren 39ad568c62 X86: enable CSE between CMP and SUB ... We perform the following: 1> Use SUB instead of CMP for i8,i16,i32 and i64 in ISel lowering. 2> Modify MachineCSE to correctly handle implicit defs. 3> Convert SUB back to CMP if possible at peephole. Removed pattern matching of (a>b) ? (a-b):0 and like, since they are handled by peephole now. rdar://11873276 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161462 91177308-0d34-0410-b5e6-96231b3b80d8		2012-08-08 00:51:41 +00:00
