--- Comment #9 from Richard Biener <rguenth at gcc dot gnu.org> --- Nothing obviously suspicious here ... I wonder if you can attach 177t.ch_vect, 178t.ifcvt and 179t.vect for the case with the single vectorized bad loop? Maybe we're running into a latent issue downstream? What happens if you disable most followup passes?
