--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> --- Created attachment 52644 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=52644&action=edit GIMPLE testcase This is a GIMPLE testcase created from the cddce2 IL of the respective ltrans unit from trunk with the match.pd hunk reverted. It does not exhibit the bug. The reason is likely different pre-caching in SCEV and/or niter estimates.
