Chris Lattner 0a9481f44f Enhance ComputeMaskedBits to know that aligned frameindexes ... have their low bits set to zero. This allows us to optimize out explicit stack alignment code like in stack-align.ll:test4 when it is redundant. Doing this causes the code generator to start turning FI+cst into FI|cst all over the place, which is general goodness (that is the canonical form) except that various pieces of the code generator don't handle OR aggressively. Fix this by introducing a new SelectionDAG::isBaseWithConstantOffset predicate, and using it in places that are looking for ADD(X,CST). The ARM backend in particular was missing a lot of addressing mode folding opportunities around OR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125470 91177308-0d34-0410-b5e6-96231b3b80d8		2011-02-13 22:25:43 +00:00
