Dan Gohman 453aa4fbf1 Generalize SCEVExpander::visitAddRecExpr's GEP persuit, and avoid ... sending SCEVUnknowns to expandAddToGEP. This avoids the need for expandAddToGEP to bend the rules and peek into SCEVUnknown expressions. Factor out the code for testing whether a SCEV can be factored by a constant for use in a GEP index. This allows it to handle SCEVAddRecExprs, by recursing. As a result, SCEVExpander can now put more things in GEP indices, so it emits fewer explicit mul instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72366 91177308-0d34-0410-b5e6-96231b3b80d8		2009-05-24 18:06:31 +00:00
