Dan Gohman eee962e1ce Teach InstCombine's ComputeMaskedBits to handle pointer expressions ... in addition to integer expressions. Rewrite GetOrEnforceKnownAlignment as a ComputeMaskedBits problem, moving all of its special alignment knowledge to ComputeMaskedBits as low-zero-bits knowledge. Also, teach ComputeMaskedBits a few basic things about Mul and PHI instructions. This improves ComputeMaskedBits-based simplifications in a few cases, but more noticeably it significantly improves instcombine's alignment detection for loads, stores, and memory intrinsics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49492 91177308-0d34-0410-b5e6-96231b3b80d8		2008-04-10 18:43:06 +00:00
