/* The opcode table.

   The format of the opcode table is:

   NAME		OPCODE		MASK		{ OPERANDS }

   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.

   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.  */
