in case the operands are constants and its difference is |1|. It should be possible in those cases to rematerialize the result using MIPS's slt and similar instructions. The small update to some of the tests in cmov.ll, sel1c.ll and sel2c.ll was needed otherwise the optimization implemented in this patch would have been triggered (difference between the operands was 1) and that would have changed the semantic of the tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196498 91177308-0d34-0410-b5e6-96231b3b80d8
