Duncan Sands 52fb846578 Teach instsimplify that X+Y>=X+Z is the same as Y>=Z if neither side overflows, ... plus some variations of this. According to my auto-simplifier this occurs a lot but usually in combination with max/min idioms. Because max/min aren't handled yet this unfortunately doesn't have much effect in the testsuite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125462 91177308-0d34-0410-b5e6-96231b3b80d8		2011-02-13 17:15:40 +00:00
