--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 43802 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43802&action=edit gcc8-pr85090-wip.patch Untested WIP; some more work is needed to get rid of the useless vextracti32x4 $0, ... insns, similarly e.g. how vec_extract_lo_v32hi deals with it. Dunno if we want in some way suggest to RA that it is less costly to use a dup operand in that case.
