--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #3) > Actually started with r15-1163-g818e760528d436ea8f6c28ef620e2bb82d456ea1 Oh ok, I figured it was a DSE change which exposed it. I am still trying to figure out how to get a gimple testcase, a C testcase with `-fno-tree-dse -fno-tree-fre -O3` does not reproduce the issue though. But maybe I am testing it incorrectly. Maybe I need -fno-tree-vectorizer too.
