- /* 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. */
