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. */
