  /* 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.  */
