You're suggesting to modify `is_reinterpret_opcode` to be like this, and call that instead of `is_move_opcode`, right?


bool VectorNode::is_reinterpret_opcode(int opc) {
  switch (opc) {
    case Op_ReinterpretHF2S:
    case Op_ReinterpretS2HF:
    case Op_MoveF2I:
    case Op_MoveD2L:
    case Op_MoveL2D:
    case Op_MoveI2F:
      return true;
    default:
      return false;
  }
}
