2594 /* The opcode table.
2595
2596 The format of the opcode table is:
2597
2598 NAME OPCODE MASK CPU CLASS SUBCLASS { OPERANDS } { FLAGS }.
2599
2600 The table is organised such that, where possible, all instructions with
2601 the same mnemonic are together in a block. When the assembler searches
2602 for a suitable instruction the entries are checked in table order, so
2603 more specific, or specialised cases should appear earlier in the table.
2604
2605 As an example, consider two instructions 'add a,b,u6' and 'add
2606 a,b,limm'. The first takes a 6-bit immediate that is encoded within the
2607 32-bit instruction, while the second takes a 32-bit immediate that is
2608 encoded in a follow-on 32-bit, making the total instruction length
2609 64-bits. In this case the u6 variant must appear first in the table, as
2610 all u6 immediates could also be encoded using the 'limm' extension,
2611 however, we want to use the shorter instruction wherever possible.
2612
2613 It is possible though to split instructions with the same mnemonic into
2614 multiple groups. However, the instructions are still checked in table
2615 order, even across groups. The only time that instructions with the
2616 same mnemonic should be split into different groups is when different
2617 variants of the instruction appear in different architectures, in which
2618 case, grouping all instructions from a particular architecture together
2619 might be preferable to merging the instruction into the main instruction
2620 table.
2621
2622 An example of this split instruction groups can be found with the 'sync'
2623 instruction. The core arc architecture provides a 'sync' instruction,
2624 while the nps instruction set extension provides 'sync.rd' and
2625 'sync.wr'. The rd/wr flags are instruction flags, not part of the
2626 mnemonic, so we end up with two groups for the sync instruction, the
2627 first within the core arc instruction table, and the second within the
2628 nps extension instructions. */
