--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 37809 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=37809&action=edit gcc6-pr69896.patch Ah, managed to reproduce. I have one patch and one partial incomplete one. It doesn't make any sense to me to use TYPE_VECTOR_SUBPARTS () == 1 vectors for the computation if it is the widest supported vector type, we should just use the element type instead. So that is what this patch does.
