--- Comment #12 from rsandifo at gcc dot gnu.org <rsandifo at gcc dot gnu.org> --- (In reply to Andrew Pinski from comment #11) > For bit_and/bit_ior, VECTOR_CST (I would assume). Ah, yeah. But then I don't think a top-level POLY_INT_CST_P cuts it. We'd have the same problem with VECTOR_CSTs containing POLY_INT_CSTs.
