130 The format of the opcode table is:
132 NAME OPCODE MASK { OPERANDS }
134 NAME is the name of the instruction.
135 OPCODE is the instruction opcode.
136 MASK is the opcode mask; this is used to tell the disassembler
137 which bits in the actual opcode must match OPCODE.
138 OPERANDS is the list of operands.
140 The disassembler reads the table in order and prints the first
141 instruction which matches, so this table is sorted to put more
142 specific instructions before more general instructions. It is also
143 sorted by major opcode. */
