--- Comment #2 from Alfie Richards <alfierichards at gcc dot gnu.org> --- Ive explored adding a simplify to match.pd and a case to tree-vect-patterns.cc but both cause other trade-offs that are sub-optimal. Interested in any thoughts on changing ifcvt behavior in this case to change the output, and adding slp patterns for this as other options.
