Dan Gohman 37fef35e88 Teach SCEVExpander's visitAddRecExpr to reuse an existing canonical ... induction variable when the addrec to be expanded does not require a wider type. This eliminates the need for IndVarSimplify to micro-manage SCEV expansions, because SCEVExpander now automatically expands them in the form that IndVarSimplify considers to be canonical. (LSR still micro-manages its SCEV expansions, because it's optimizing for the target, rather than for other optimizations.) Also, this uses the new getAnyExtendExpr, which has more clever expression simplification logic than the IndVarSimplify code it replaces, and this cleans up some ugly expansions in code such as the included masked-iv.ll testcase. llvm-svn: 73294		2009-06-13 16:25:49 +00:00
