Chris Lattner 8d96964e29 Generalize not and neg comparison testers to allow constant to be considered not'able and neg'able. This ... allows optimization of this: int %test4(int %A, int %B) { %a = xor int %A, -1 %c = and int %a, 5 ; 5 = ~c2 %d = xor int %c, -1 ret int %d } into this: int %test4(int %A, int %B) { ; No predecessors! %c.demorgan = or int %A, -6 ; <int> [#uses=1] ret int %c.demorgan } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5736 91177308-0d34-0410-b5e6-96231b3b80d8		2003-03-10 23:06:50 +00:00
