  /* A string of characters which describe the operands.

     Valid characters are:

     ,        Itself.  The character appears in the assembly code.

     a        RA.  The register number is in bits 8-15 of the instruction.

     b        RB.  The register number is in bits 0-7 of the instruction.

     c        RC.  The register number is in bits 16-23 of the instruction.

     i        An immediate operand is in bits 0-7 of the instruction.

     x        Bits 0-7 and 16-23 of the instruction are bits 0-7 and 8-15

              (respectively) of the immediate operand.

     h        Same as x but the instruction contains bits 16-31 of the

              immediate operand.

     X        Same as x but bits 16-31 of the signed immediate operand

              are set to 1 (thus the operand is always negative).

     P,A      Bits 0-7 and 16-23 of the instruction are bits 2-9 and 10-17

              (respectively) of the immediate operand.

              P=PC-relative, sign-extended to 32 bits.

              A=Absolute, zero-extended to 32 bits.

     e        CE bit (bit 23) for a load/store instruction.

     n        Control field (bits 16-22) for a load/store instruction.

     v        Immediate operand in bits 16-23 of the instruction.

              (used for trap numbers).

     s        SA.  Special-purpose register number in bits 8-15

              of the instruction.

     u        UI--bit 7 of the instruction.

     r        RND--bits 4-6 of the instruction.

     d        FD--bits 2-3 of the instruction.

     f        FS--bits 0-1 of the instruction.

     I        ID--bits 16-17 of the instruction.

     Extensions for 29050:

     d        FMT--bits 2-3 of the instruction (not really new).

     f        ACN--bits 0-1 of the instruction (not really new).

     F        FUNC--Special function in bits 18-21 of the instruction.

     C        ACN--bits 16-17 specifying the accumlator register.  */
