*

* unsigned rd_mask; An appropriate mask to isolate the bit field
* within a word, and'ed with val
*
* int rd_shift; A shift amount to be done to the isolated

* for symbolic value names in rd_values
*
* char *rd_name; If non-null, a bit field name to label any
* out from rd_format or searching rd_values.
* if neither rd_format or rd_values is non-null
* rd_name is printed only if the isolated
* bit field is non-null.
*
* char *rd_format; If non-null, the shifted bit field value
* is printed using this format.

* Reg_valuesp is a pointer to an array of struct reg_values which pairs
* numeric values (rv_value) with symbolic names (rv_name). The array is
* terminated with a reg_values entry that has a null pointer for the
* rv_name field. When %n or %N is used rd_values are searched and the
* symbolic value is printed if a match is found, if no match is found
* "???" is printed.
*
* printf("%C", val);
