--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Mine. Probably the change that would make two patterns at the same stmt
unrecognizable and
static vect_recog_func vect_vect_recog_func_ptrs[NUM_PATTERNS] = {
{ vect_recog_widen_mult_pattern, "widen_mult" },
{ vect_recog_widen_sum_pattern, "widen_sum" },
{ vect_recog_dot_prod_pattern, "dot_prod" },
which means widen_sum should be only after dot_prod detection. Maybe you
can verify if swapping them passes testing on power (until I get to this
myself).
