145 The format of the opcode table is:
147 NAME OPCODE MASK { OPERANDS }
149 NAME is the name of the instruction.
150 OPCODE is the instruction opcode.
151 MASK is the opcode mask; this is used to tell the disassembler
152 which bits in the actual opcode must match OPCODE.
153 OPERANDS is the list of operands.
155 The disassembler reads the table in order and prints the first
156 instruction which matches, so this table is sorted to put more
157 specific instructions before more general instructions. It is also
158 sorted by major opcode. */
