--- Comment #4 from H.J. Lu <hjl.tools at gmail dot com> ---
Why do we have

define_expand "sse2_umulv1siv1di3"
  [(set (match_operand:V1DI 0 "register_operand")
        (mult:V1DI
          (zero_extend:V1DI
            (vec_select:V1SI
              (match_operand:V2SI 1 "nonimmediate_operand")
              (parallel [(const_int 0)])))
          (zero_extend:V1DI
            (vec_select:V1SI
              (match_operand:V2SI 2 "nonimmediate_operand")
              (parallel [(const_int 0)])))))]
  "TARGET_SSE2"
  "ix86_fixup_binary_operands_no_copy (MULT, V2SImode, operands);")

i386-builtin.def:BDESC (OPTION_MASK_ISA_SSE2 | OPTION_MASK_ISA_MMX, 0,
CODE_FOR_sse2_umulv1siv1di3, "__builtin_ia32_pmuludq", IX86_BUILTIN_PMULUDQ,
UNKNOWN, (int) V1DI_FTYPE_V2SI_V2SI)

sse2_umulv1siv1di3 isn't available with MMX.
