--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I think it doesn't hurt to punt instead of ICEing in the generic code, but as Richard said, if it is not a target bug, it is at least a very strange choice, how can a mode like V2DImode be preferred simd mode for DImode when it is not supported with -maltivec -mno-vsx? I think it should just return word_mode in that case.
