 705 /* The opcode table.
 706
 707    The format of the opcode table is:
 708
 709    NAME OPCODE MASK { OPERANDS }
 710
 711    NAME         is the name of the instruction.
 712
 713    OPCODE       is the instruction opcode.
 714
 715    MASK         is the opcode mask; this is used to tell the disassembler
 716                 which bits in the actual opcode must match OPCODE.
 717
 718    OPERANDS     is the list of operands.
 719
 720    The preceding macros merge the text of the OPCODE and MASK fields.
 721
 722    The disassembler reads the table in order and prints the first
 723    instruction which matches, so this table is sorted to put more
 724    specific instructions before more general instructions.
 725
 726    Otherwise, it is sorted by major opcode and minor function code.
 727
 728    There are three classes of not-really-instructions in this table:
 729
 730    ALIAS        is another name for another instruction.  Some of
 731                 these come from the Architecture Handbook, some
 732                 come from the original gas opcode tables.  In all
 733                 cases, the functionality of the opcode is unchanged.
 734
 735    PSEUDO       a stylized code form endorsed by Chapter A.4 of the
 736                 Architecture Handbook.
 737
 738    EXTRA        a stylized code form found in the original gas tables.
 739
 740    And two annotations:
 741
 742    EV56 BUT     opcodes that are officially introduced as of the ev56,
 743                 but with defined results on previous implementations.
 744
 745    EV56 UNA     opcodes that were introduced as of the ev56 with
 746                 presumably undefined results on previous implementations
 747                 that were not assigned to a particular extension.
