[Bug target/31478] New: Typo in sse2_umulv2siv2di3 pattern

[hjl at lucon dot org]

There are

(define_insn "sse2_umulv2siv2di3"
  [(set (match_operand:V2DI 0 "register_operand" "=x")
        (mult:V2DI
          (zero_extend:V2DI
            (vec_select:V2SI
              (match_operand:V4SI 1 "nonimmediate_operand" "%0")
              (parallel [(const_int 0) (const_int 2)])))
          (zero_extend:V2DI 
            (vec_select:V2SI
              (match_operand:V4SI 2 "nonimmediate_operand" "xm")
              (parallel [(const_int 0) (const_int 2)])))))]
  "TARGET_SSE2 && ix86_binary_operator_ok (MULT, V8HImode, operands)"
  "pmuludq\t{%2, %0|%0, %2}"
  [(set_attr "type" "sseimul")
   (set_attr "mode" "TI")])

I have 2 questions:

1. Is ix86_binary_operator_ok needed here?
2. If yes, why is V8HImode used?
