664 /* The opcode table.
665 
666    The format of the opcode table is:
667 
668    NAME OPCODE MASK { OPERANDS }
669 
670    NAME		is the name of the instruction.
671 
672    OPCODE	is the instruction opcode.
673 
674    MASK		is the opcode mask; this is used to tell the disassembler
675 		which bits in the actual opcode must match OPCODE.
676 
677    OPERANDS	is the list of operands.
678 
679    The preceding macros merge the text of the OPCODE and MASK fields.
680 
681    The disassembler reads the table in order and prints the first
682    instruction which matches, so this table is sorted to put more
683    specific instructions before more general instructions.
684 
685    Otherwise, it is sorted by major opcode and minor function code.
686 
687    There are three classes of not-really-instructions in this table:
688 
689    ALIAS	is another name for another instruction.  Some of
690 		these come from the Architecture Handbook, some
691 		come from the original gas opcode tables.  In all
692 		cases, the functionality of the opcode is unchanged.
693 
694    PSEUDO	a stylized code form endorsed by Chapter A.4 of the
695 		Architecture Handbook.
696 
697    EXTRA	a stylized code form found in the original gas tables.
698 
699    And two annotations:
700 
701    EV56 BUT	opcodes that are officially introduced as of the ev56,
702 		but with defined results on previous implementations.
703 
704    EV56 UNA	opcodes that were introduced as of the ev56 with
705 		presumably undefined results on previous implementations
706 		that were not assigned to a particular extension.
