use a callback system like interp__builtin_elementwise_int_binop:
```cpp
return interp__builtin_ia32_pmadd(S, OpPC, Call,
[](const APSInt &LoLHS, const APSInt &HiLHS, const APSInt &HiRHS, const
APSInt &HiRHS) {
unsigned BitWidth = 2 * LHS.getBitWidth();
return (LoLHS.sext(BitWidth) * LoRHS.sext(BitWidth)) +
(HiLHS.sext(BitWidth) * HiRHS.sext(BitWidth));
});
