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