 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.
