/* The opcode table.

   The format of the opcode table is:

   NAME		OPCODE			MASK		       { OPERANDS }	   MEMOP    PROCESSOR

   NAME is the name of the instruction.
   OPCODE is the instruction opcode.
   MASK is the opcode mask; this is used to tell the disassembler
     which bits in the actual opcode must match OPCODE.
   OPERANDS is the list of operands.
   MEMOP specifies which operand (if any) is a memory operand.
   PROCESSORS specifies which CPU(s) support the opcode.

   The disassembler reads the table in order and prints the first
   instruction which matches, so this table is sorted to put more
   specific instructions before more general instructions.  It is also
   sorted by major opcode.

   The table is also sorted by name.  This is used by the assembler.
   When parsing an instruction the assembler finds the first occurance
   of the name of the instruciton in this table and then attempts to
   match the instruction's arguments with description of the operands
   associated with the entry it has just found in this table.  If the
   match fails the assembler looks at the next entry in this table.
   If that entry has the same name as the previous entry, then it
   tries to match the instruction against that entry and so on.  This
   is how the assembler copes with multiple, different formats of the
   same instruction.  */
