Dan Gohman 6ebfd72f37 Fix SCEVExpander::visitAddRecExpr so that it remembers the induction variable ... it inserted rather than using LoopInfo::getCanonicalInductionVariable to rediscover it, since that doesn't work on non-canonical loops. This fixes infinite recurrsion on such loops; PR7562. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109419 91177308-0d34-0410-b5e6-96231b3b80d8		2010-07-26 18:28:14 +00:00
