 548
 549    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.  */
