/* 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. */
