--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
Note the rev. in question can only have made a previously latent issue exposed.

It's also not clear to me why this isn't a target issue given there's not
enough information on who introduces "bad" RTL?  Hope Jeff might be able to
help and Martin with reduction.
