549 The format of the opcode table is:
551 NAME OPCODE MASK { OPERANDS } MEMOP PROCESSOR
553 NAME is the name of the instruction.
554 OPCODE is the instruction opcode.
555 MASK is the opcode mask; this is used to tell the disassembler
556 which bits in the actual opcode must match OPCODE.
557 OPERANDS is the list of operands.
558 MEMOP specifies which operand (if any) is a memory operand.
559 PROCESSORS specifies which CPU(s) support the opcode.
561 The disassembler reads the table in order and prints the first
562 instruction which matches, so this table is sorted to put more
563 specific instructions before more general instructions. It is also
564 sorted by major opcode.
566 The table is also sorted by name. This is used by the assembler.
567 When parsing an instruction the assembler finds the first occurance
568 of the name of the instruciton in this table and then attempts to
569 match the instruction's arguments with description of the operands
570 associated with the entry it has just found in this table. If the
571 match fails the assembler looks at the next entry in this table.
572 If that entry has the same name as the previous entry, then it
573 tries to match the instruction against that entry and so on. This
574 is how the assembler copes with multiple, different formats of the
