Updating X_md on port's side would be another option. For example,
this works too:

    expressionS ex;
    ex.X_md = (operand->flags &
        (PPC_OPERAND_GPR | PPC_OPERAND_FPR | PPC_OPERAND_VR
        | PPC_OPERAND_VSR | PPC_OPERAND_CR_BIT | PPC_OPERAND_CR_REG
        | PPC_OPERAND_SPR | PPC_OPERAND_GQR | PPC_OPERAND_ACC));
    expression (&ex);
