112 The format of the opcode table is:
114 NAME OPCODE MASK { OPERANDS }
116 NAME is the name of the instruction.
117 OPCODE is the instruction opcode.
118 MASK is the opcode mask; this is used to tell the disassembler
119 which bits in the actual opcode must match OPCODE.
120 OPERANDS is the list of operands.
122 The disassembler reads the table in order and prints the first
123 instruction which matches, so this table is sorted to put more
124 specific instructions before more general instructions. It is also
125 sorted by major opcode. */
