--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
We've moved pcom after loop vectorization because of this. But yes,
moving pcom further down is a possibility although we lack DCE after SLP
(prefetching and IVOPTs might be also confused because of that, so it
seems like a separate problem).
So yes, moving pcom after SLP and before loop prefetching sounds reasonable
to me.
