--- Comment #8 from Jeffrey A. Law <law at gcc dot gnu.org> --- I don't think so -- the goal here is to optimize this in gimple so that all targets benefit rather than every target having to customize a solution for this idiom. If Roger's patch is sound you might even be able to simplify the ppc backend eve so slightly.
