--- 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?
