Manman Ren 9236362a64 X86: optimize generated code for integer ABS ... This patch will generate the following for integer ABS: movl %edi, %eax negl %eax cmovll %edi, %eax INSTEAD OF movl %edi, %ecx sarl $31, %ecx leal (%rdi,%rcx), %eax xorl %ecx, %eax There exists a target-independent DAG combine for integer ABS, which converts integer ABS to sar+add+xor. For X86, we match this pattern back to neg+cmov. This is implemented in PerformXorCombine. rdar://10695237 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158175 91177308-0d34-0410-b5e6-96231b3b80d8		2012-06-07 22:39:10 +00:00
