2229 /* The opcode table.
2230
2231 The format of the opcode table is:
2232
2233 NAME OPCODE MASK CPU CLASS SUBCLASS { OPERANDS } { FLAGS }.
2234
2235 The table is organised such that, where possible, all instructions with
2236 the same mnemonic are together in a block. When the assembler searches
2237 for a suitable instruction the entries are checked in table order, so
2238 more specific, or specialised cases should appear earlier in the table.
2239
2240 As an example, consider two instructions 'add a,b,u6' and 'add
2241 a,b,limm'. The first takes a 6-bit immediate that is encoded within the
2242 32-bit instruction, while the second takes a 32-bit immediate that is
2243 encoded in a follow-on 32-bit, making the total instruction length
2244 64-bits. In this case the u6 variant must appear first in the table, as
2245 all u6 immediates could also be encoded using the 'limm' extension,
2246 however, we want to use the shorter instruction wherever possible.
2247
2248 It is possible though to split instructions with the same mnemonic into
2249 multiple groups. However, the instructions are still checked in table
2250 order, even across groups. The only time that instructions with the
2251 same mnemonic should be split into different groups is when different
2252 variants of the instruction appear in different architectures, in which
2253 case, grouping all instructions from a particular architecture together
2254 might be preferable to merging the instruction into the main instruction
2255 table.
2256
2257 An example of this split instruction groups can be found with the 'sync'
2258 instruction. The core arc architecture provides a 'sync' instruction,
2259 while the nps instruction set extension provides 'sync.rd' and
2260 'sync.wr'. The rd/wr flags are instruction flags, not part of the
2261 mnemonic, so we end up with two groups for the sync instruction, the
2262 first within the core arc instruction table, and the second within the
2263 nps extension instructions. */

2559
2560 The first part of each ARC_LONG_OPCODE is the base ARC_OPCODE, this is
2561 either the 16 or 32 bit base instruction, and its opcode list will
2562 always end in a LIMM.
2563
2564 The rest of the ARC_LONG_OPCODE describes how to build the LIMM from the
2565 instruction operands. There are therefore two lists of operands for
2566 each ARC_LONG_OPCODE, the second list contains operands that are merged
2567 into the limm template, in the same way that a standard 32-bit
2568 instruction is built. This generated limm is then added to the list of
2569 tokens that is passed to the standard instruction encoder, along with
2570 the first list of operands (from the base arc_opcode).
2571
2572 The first list of operands then, describes how to build the base
2573 instruction, and includes the 32-bit limm that was previously generated
2574 as the last operand.
2575
2576 In most cases operands are either encoded into the base instruction or
2577 into the limm. When this happens the operand slot will be filled with
2578 an operand identifier in one list, and will be IGNORED in the other
2579 list, this special operand value causes the operand to be ignored,
2580 without being encoded at this point.
2581
2582 However, in some cases, an operand is split between the base instruction
2583 and the 32-bit limm, in this case the operand slot will be filled in
2584 both operand lists (see mov4b for one example of this). */
