/* 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.
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. */
