--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
find_widening_optab_handler_and_mode simply does not handle
op=umadd_widen_optab, to_mode=E_USAmode, from_mode=E_UHQmode
Probably the bug is upstream in the widening_mul pass which
likely looks trough the apparent widening of the _Fract arg
to the _Accum multiplication.
