Sanjoy Das 7ac8ad9906 Be wary of abnormal exits from loop when exploiting UB ... We can safely rely on a NoWrap add recurrence causing UB down the road only if we know the loop does not have a exit expressed in a way that is opaque to ScalarEvolution (e.g. by a function call that conditionally calls exit(0)). I believe with this change PR28012 is fixed. Note: I had to change some llvm-lit tests in LoopReroll, since it looks like they were depending on this incorrect behavior. llvm-svn: 272237		2016-06-09 01:13:59 +00:00
