--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The vectorizer looks ok though:
  mask_patt_37.15_52 = [vec_unpack_lo_expr] mask__9.14_51;
  mask_patt_37.15_53 = [vec_unpack_hi_expr] mask__9.14_51;
  vect_patt_36.18_57 = .COND_ADD (mask_patt_37.15_52, vect__10.16_54,
vect_total_21.17_56, vect__10.16_54);
  vect_patt_36.18_58 = .COND_ADD (mask_patt_37.15_53, vect__10.16_55,
vect_patt_36.18_57, vect__10.16_55);


 /* A ? B : B -> B.  */
 (simplify
  (cnd @0 @1 @1)
  @1)

Confirmed, I think COND_ADD  folding goes wrong.
