1540 /* The opcode table.
1541
1542    The format of the opcode table is:
1543
1544    NAME OPCODE MASK CPU CLASS SUBCLASS { OPERANDS } { FLAGS }.
1545
1546    The table is organised such that, where possible, all instructions with
1547    the same mnemonic are together in a block.  When the assembler searches
1548    for a suitable instruction the entries are checked in table order, so
1549    more specific, or specialised cases should appear earlier in the table.
1550
1551    As an example, consider two instructions 'add a,b,u6' and 'add
1552    a,b,limm'.  The first takes a 6-bit immediate that is encoded within the
1553    32-bit instruction, while the second takes a 32-bit immediate that is
1554    encoded in a follow-on 32-bit, making the total instruction length
1555    64-bits.  In this case the u6 variant must appear first in the table, as
1556    all u6 immediates could also be encoded using the 'limm' extension,
1557    however, we want to use the shorter instruction wherever possible.
1558
1559    It is possible though to split instructions with the same mnemonic into
1560    multiple groups.  However, the instructions are still checked in table
1561    order, even across groups.  The only time that instructions with the
1562    same mnemonic should be split into different groups is when different
1563    variants of the instruction appear in different architectures, in which
1564    case, grouping all instructions from a particular architecture together
1565    might be preferable to merging the instruction into the main instruction
1566    table.
1567
1568    An example of this split instruction groups can be found with the 'sync'
1569    instruction.  The core arc architecture provides a 'sync' instruction,
1570    while the nps instruction set extension provides 'sync.rd' and
1571    'sync.wr'.  The rd/wr flags are instruction flags, not part of the
1572    mnemonic, so we end up with two groups for the sync instruction, the
1573    first within the core arc instruction table, and the second within the
1574    nps extension instructions.  */
