--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
On the gimple level this is about canonicalization. Now that we have a andn
optab RTL expansion/insn selection should do the trick but I wonder why
combine doesn't - that looks like a target bug or a simplify-rtx issue
(again a missed canonicalization rule?)
