--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I think Richard needs to explain why he changed the function from using GET_MODE_WIDER_MODE to the assert + simple iteration on modes, it isn't clear from his patch why it was changed. Does that not really work with the variable sized modes on SVE?
