Sanjoy Das 7ebbc8de2f Fix bug 22641 ... The bug was a result of getPreStartForExtend interpreting nsw/nuw flags on an add recurrence more strongly than is legal. {S,+,X}<nsw> implies S+X is nsw only if the backedge of the loop is taken at least once. Differential Revision: http://reviews.llvm.org/D7808 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@230275 91177308-0d34-0410-b5e6-96231b3b80d8		2015-02-23 22:55:13 +00:00
