--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Richard Biener from comment #3) > Note there's still code in tree-vect-patterns.cc creating those and code in > tree-vect-stmts.cc might use gimple_extract on them. Now we assert this won't happen any more with r15-4695-gd17e672ce82e69 . I am going to test a patch which removes the places I saw the special handling.
