--- Comment #3 from Daniel Henrique Barboza <dbarboza at ventanamicro dot com> --- I didn't find an existing pattern for it either in match.pd or tree-ssa passes. The existing patterns I found that matched this bug are on match.pd but are vector specific. Just sent a patch to the ML with a proposed fix.
