Jim Grosbach 51a0280d29 DAG: Combine (and (setne X, 0), (setne X, -1)) -> (setuge (add X, 1), 2) ... A common idiom is to use zero and all-ones as sentinal values and to check for both in a single conditional ("x != 0 && x != (unsigned)-1"). That generates code, for i32, like: testl %edi, %edi setne %al cmpl $-1, %edi setne %cl andb %al, %cl With this transform, we generate the simpler: incl %edi cmpl $1, %edi seta %al Similar improvements for other integer sizes and on other platforms. In general, combining the two setcc instructions into one is better. rdar://14689217 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188315 91177308-0d34-0410-b5e6-96231b3b80d8		2013-08-13 21:30:58 +00:00
