--- Comment #26 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #25) > The FRE redundant store removal went away in r273135 aka PR91091 fix. I'll see whether I can do something about FRE. Redundant store removal there isn't a good fit and thus not easy to get semantically correct.
