Sanjoy Das caee94bbb4 Revert some changes that were made to fix PR20680. ... This re-lands change r230921. r230921 was reverted because it broke a clang test; a checkin fixing the clang test will be commited shortly. Summary: As far as I can tell, the real bug causing the issue was fixed in r230533. SCEVExpander should mark an increment operation as nuw or nsw only if it can *prove* that the operation does not overflow. There shouldn't be any situation where we have to do something different because of no-wrap flags generated by SCEVExpander. Revert "IndVarSimplify: Allow LFTR to fire more often" This reverts commit 1ade0f0faa (SVN: 222213). Revert "IndVarSimplify: Don't let LFTR compare against a poison value" This reverts commit c0f2b8b528 (SVN: 217102).
