--- Comment #10 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Andrew Pinski from comment #9) > Oh wait the problem is this is before lowering but SVE vectors can't be > lowered. > > I think maybe the lowering pass should handle the case where: > !target_supports_op_p (type, TRUNC_MOD_EXPR, optab_vector) && > target_supports_op_p (type, TRUNC_DIV_EXPR, optab_vector) && > target_supports_op_p (type, MULT_EXPR, optab_vector) && target_supports_op_p > (type, MINUS_EXPR, optab_vector) That would also help if you add that lowering to vect lowering: ``` #define vect16 __attribute__((vector_size(16))) vect16 unsigned g(vect16 unsigned a, vect16 unsigned b) { return a % b; } ```
