Dan Gohman 23e8b71526 Teach InstCombine's ComputeMaskedBits what SelectionDAG's ... ComputeMaskedBits knows about cttz, ctlz, and ctpop. Teach SelectionDAG's ComputeMaskedBits what InstCombine's knows about SRem. And teach them both some things about high bits in Mul, UDiv, URem, and Sub. This allows instcombine and dagcombine to eliminate sign-extension operations in several new cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50358 91177308-0d34-0410-b5e6-96231b3b80d8		2008-04-28 17:02:21 +00:00
