   The format of the opcode table is:
550
 
551
   NAME         OPCODE                  MASK                   { OPERANDS }        MEMOP    PROCESSOR
552
 
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.
560
 
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.
565
 
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
575
   same instruction.  */
