InstCombine: variations on 0xffffffff - x >= 4 The following transforms are valid if -C is a power of 2: (icmp ugt (xor X, C), ~C) -> (icmp ult X, C) (icmp ult (xor X, C), -C) -> (icmp uge X, C) These are nice, they get rid of the xor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185915 91177308-0d34-0410-b5e6-96231b3b80d8
