584 | ||
585 | The format of the opcode table is: | |
586 | ||
587 | NAME OPCODE MASK { OPERANDS } MEMOP PROCESSOR | |
588 | ||
589 | NAME is the name of the instruction. | |
590 | OPCODE is the instruction opcode. | |
591 | MASK is the opcode mask; this is used to tell the disassembler | |
592 | which bits in the actual opcode must match OPCODE. | |
593 | OPERANDS is the list of operands. | |
594 | MEMOP specifies which operand (if any) is a memory operand. | |
595 | PROCESSORS specifies which CPU(s) support the opcode. | |
596 | ||
597 | The disassembler reads the table in order and prints the first | |
598 | instruction which matches, so this table is sorted to put more | |
599 | specific instructions before more general instructions. It is also | |
600 | sorted by major opcode. | |
601 | ||
602 | The table is also sorted by name. This is used by the assembler. | |
603 | When parsing an instruction the assembler finds the first occurance | |
604 | of the name of the instruciton in this table and then attempts to | |
605 | match the instruction's arguments with description of the operands | |
606 | associated with the entry it has just found in this table. If the | |
607 | match fails the assembler looks at the next entry in this table. | |
608 | If that entry has the same name as the previous entry, then it | |
609 | tries to match the instruction against that entry and so on. This | |
610 | is how the assembler copes with multiple, different formats of the | |
611 | same instruction. */ | |
