 /* Print an instruction operand X on file FILE.
    CODE is the code from the %-spec that requested printing this operand;
    if `%z3' was used to print operand 3, then CODE is 'z'.
-   On the Vax, the codes used are:
-   `#', indicating that either `d' or `g' should be printed,
-   depending on whether we're using dfloat or gfloat.
-   `C', indicating the reverse of the condition name specified by the
-   operand.
-   `P', indicating one plus a constant operand
-   `N', indicating the one's complement of a constant operand
-   `H', indicating the low-order 16 bits of the one's complement of a constant
-   `B', similarly for the low-order 8 bits.  */
