29 | Valid characters are: | |
30 | , Itself. The character appears in the assembly code. | |
31 | a RA. The register number is in bits 8-15 of the instruction. | |
32 | b RB. The register number is in bits 0-7 of the instruction. | |
33 | c RC. The register number is in bits 16-23 of the instruction. | |
34 | i An immediate operand is in bits 0-7 of the instruction. | |
35 | x Bits 0-7 and 16-23 of the instruction are bits 0-7 and 8-15 | |
36 | (respectively) of the immediate operand. | |
37 | h Same as x but the instruction contains bits 16-31 of the | |
38 | immediate operand. | |
39 | X Same as x but bits 16-31 of the signed immediate operand | |
40 | are set to 1 (thus the operand is always negative). | |
41 | P,A Bits 0-7 and 16-23 of the instruction are bits 2-9 and 10-17 | |
42 | (respectively) of the immediate operand. | |
43 | P=PC-relative, sign-extended to 32 bits. | |
44 | A=Absolute, zero-extended to 32 bits. | |
45 | e CE bit (bit 23) for a load/store instruction. | |
46 | n Control field (bits 16-22) for a load/store instruction. | |
47 | v Immediate operand in bits 16-23 of the instruction. | |
48 | (used for trap numbers). | |
49 | s SA. Special-purpose register number in bits 8-15 | |
50 | of the instruction. | |
51 | u UI--bit 7 of the instruction. | |
52 | r RND--bits 4-6 of the instruction. | |
53 | d FD--bits 2-3 of the instruction. | |
54 | f FS--bits 0-1 of the instruction. */ | |
