2612 /* The opcode table.
2613
2614    The format of the opcode table is:
2615
2616    NAME OPCODE MASK CPU CLASS SUBCLASS { OPERANDS } { FLAGS }.
2617
2618    The table is organised such that, where possible, all instructions with
2619    the same mnemonic are together in a block.  When the assembler searches
2620    for a suitable instruction the entries are checked in table order, so
2621    more specific, or specialised cases should appear earlier in the table.
2622
2623    As an example, consider two instructions 'add a,b,u6' and 'add
2624    a,b,limm'.  The first takes a 6-bit immediate that is encoded within the
2625    32-bit instruction, while the second takes a 32-bit immediate that is
2626    encoded in a follow-on 32-bit, making the total instruction length
2627    64-bits.  In this case the u6 variant must appear first in the table, as
2628    all u6 immediates could also be encoded using the 'limm' extension,
2629    however, we want to use the shorter instruction wherever possible.
2630
2631    It is possible though to split instructions with the same mnemonic into
2632    multiple groups.  However, the instructions are still checked in table
2633    order, even across groups.  The only time that instructions with the
2634    same mnemonic should be split into different groups is when different
2635    variants of the instruction appear in different architectures, in which
2636    case, grouping all instructions from a particular architecture together
2637    might be preferable to merging the instruction into the main instruction
2638    table.
2639
2640    An example of this split instruction groups can be found with the 'sync'
2641    instruction.  The core arc architecture provides a 'sync' instruction,
2642    while the nps instruction set extension provides 'sync.rd' and
2643    'sync.wr'.  The rd/wr flags are instruction flags, not part of the
2644    mnemonic, so we end up with two groups for the sync instruction, the
2645    first within the core arc instruction table, and the second within the
2646    nps extension instructions.  */
