502 | The format of the opcode table is: | |
503 | ||
504 | NAME OPCODE MASK { OPERANDS } MEMOP PROCESSOR | |
505 | ||
506 | NAME is the name of the instruction. | |
507 | OPCODE is the instruction opcode. | |
508 | MASK is the opcode mask; this is used to tell the disassembler | |
509 | which bits in the actual opcode must match OPCODE. | |
510 | OPERANDS is the list of operands. | |
511 | MEMOP specifies which operand (if any) is a memory operand. | |
512 | PROCESSORS specifies which CPU(s) support the opcode. | |
47b0e7ad | 513 | |
252b5132 RH |
514 | The disassembler reads the table in order and prints the first |
515 | instruction which matches, so this table is sorted to put more | |
516 | specific instructions before more general instructions. It is also | |
517 | sorted by major opcode. | |
518 | ||
519 | The table is also sorted by name. This is used by the assembler. | |
520 | When parsing an instruction the assembler finds the first occurance | |
521 | of the name of the instruciton in this table and then attempts to | |
522 | match the instruction's arguments with description of the operands | |
523 | associated with the entry it has just found in this table. If the | |
524 | match fails the assembler looks at the next entry in this table. | |
525 | If that entry has the same name as the previous entry, then it | |
526 | tries to match the instruction against that entry and so on. This | |
527 | is how the assembler copes with multiple, different formats of the | |
528 | same instruction. */ | |
