576 /* The opcode table.
577
578 The format of the opcode table is:
579
580 NAME OPCODE MASK { OPERANDS } MEMOP PROCESSOR
581
582 NAME is the name of the instruction.
583 OPCODE is the instruction opcode.
584 MASK is the opcode mask; this is used to tell the disassembler
585 which bits in the actual opcode must match OPCODE.
586 OPERANDS is the list of operands.
587 MEMOP specifies which operand (if any) is a memory operand.
588 PROCESSORS specifies which CPU(s) support the opcode.
589
590 The disassembler reads the table in order and prints the first
591 instruction which matches, so this table is sorted to put more
592 specific instructions before more general instructions. It is also
593 sorted by major opcode.
594
595 The table is also sorted by name. This is used by the assembler.
596 When parsing an instruction the assembler finds the first occurance
597 of the name of the instruciton in this table and then attempts to
598 match the instruction's arguments with description of the operands
599 associated with the entry it has just found in this table. If the
600 match fails the assembler looks at the next entry in this table.
601 If that entry has the same name as the previous entry, then it
602 tries to match the instruction against that entry and so on. This
603 is how the assembler copes with multiple, different formats of the
604 same instruction. */
