524 The format of the opcode table is:
526 NAME OPCODE MASK { OPERANDS } MEMOP PROCESSOR
528 NAME is the name of the instruction.
529 OPCODE is the instruction opcode.
530 MASK is the opcode mask; this is used to tell the disassembler
531 which bits in the actual opcode must match OPCODE.
532 OPERANDS is the list of operands.
533 MEMOP specifies which operand (if any) is a memory operand.
534 PROCESSOR specifies which CPUs support the opcode.
536 The disassembler reads the table in order and prints the first
537 instruction which matches, so this table is sorted to put more
538 specific instructions before more general instructions. It is also
539 sorted by major opcode.
541 The table is also sorted by name. This is used by the assembler.
542 When parsing an instruction the assembler finds the first occurance
543 of the name of the instruciton in this table and then attempts to
544 match the instruction's arguments with description of the operands
545 associated with the entry it has just found in this table. If the
546 match fails the assembler looks at the next entry in this table.
547 If that entry has the same name as the previous entry, then it
548 tries to match the instruction against that entry and so on. This
549 is how the assembler copes with multiple, different formats of the
