IndVarSimplify assumes scAddRecExpr to be expanded in literal form instead of canonical form by calling disableCanonicalMode after it creates SCEVExpander. When CanonicalMode is disabled, SCEVExpander::expand should always return PHI node for scAddRecExpr. r259736 broke the assumption. The fix is to let SCEVExpander::expand skip the reuse Value logic if CanonicalMode is false. In addition, Besides IndVarSimplify, LSR pass also calls disableCanonicalMode before doing rewrite. We can remove the original check of LSRMode in reuse Value logic and use CanonicalMode instead. llvm-svn: 260174 |
