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. */
