Manman Ren 91c5346d91 X86: replace SUB with CMP if possible ... This patch will optimize the following movq %rdi, %rax subq %rsi, %rax cmovsq %rsi, %rdi movq %rdi, %rax to cmpq %rsi, %rdi cmovsq %rsi, %rdi movq %rdi, %rax Perform this optimization if the actual result of SUB is not used. rdar: 11540023 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157755 91177308-0d34-0410-b5e6-96231b3b80d8		2012-05-31 17:20:29 +00:00
