886a2506 | 2130 | /* The opcode table. |
0d2bcfaf | 2131 | |
886a2506 | 2132 | The format of the opcode table is: |
0d2bcfaf | 2133 | |
1328504b AB |
2134 | NAME OPCODE MASK CPU CLASS SUBCLASS { OPERANDS } { FLAGS }. |
2135 | ||
2136 | The table is organised such that, where possible, all instructions with | |
2137 | the same mnemonic are together in a block. When the assembler searches | |
2138 | for a suitable instruction the entries are checked in table order, so | |
2139 | more specific, or specialised cases should appear earlier in the table. | |
2140 | ||
2141 | As an example, consider two instructions 'add a,b,u6' and 'add | |
2142 | a,b,limm'. The first takes a 6-bit immediate that is encoded within the | |
2143 | 32-bit instruction, while the second takes a 32-bit immediate that is | |
2144 | encoded in a follow-on 32-bit, making the total instruction length | |
2145 | 64-bits. In this case the u6 variant must appear first in the table, as | |
2146 | all u6 immediates could also be encoded using the 'limm' extension, | |
2147 | however, we want to use the shorter instruction wherever possible. | |
2148 | ||
2149 | It is possible though to split instructions with the same mnemonic into | |
2150 | multiple groups. However, the instructions are still checked in table | |
2151 | order, even across groups. The only time that instructions with the | |
2152 | same mnemonic should be split into different groups is when different | |
2153 | variants of the instruction appear in different architectures, in which | |
2154 | case, grouping all instructions from a particular architecture together | |
2155 | might be preferable to merging the instruction into the main instruction | |
2156 | table. | |
2157 | ||
2158 | An example of this split instruction groups can be found with the 'sync' | |
2159 | instruction. The core arc architecture provides a 'sync' instruction, | |
2160 | while the nps instruction set extension provides 'sync.rd' and | |
2161 | 'sync.wr'. The rd/wr flags are instruction flags, not part of the | |
2162 | mnemonic, so we end up with two groups for the sync instruction, the | |
2163 | first within the core arc instruction table, and the second within the | |
2164 | nps extension instructions. */ | |

2458 | /* The following instructions are all either 48 or 64 bits long, and | |
2459 | require special handling in the assembler and disassembler. | |
2460 | ||
2461 | The first part of each ARC_LONG_OPCODE is the base ARC_OPCODE, this is | |
2462 | either the 16 or 32 bit base instruction, and its opcode list will | |
2463 | always end in a LIMM. | |
2464 | ||
2465 | The rest of the ARC_LONG_OPCODE describes how to build the LIMM from the | |
2466 | instruction operands. There are therefore two lists of operands for | |
2467 | each ARC_LONG_OPCODE, the second list contains operands that are merged | |
2468 | into the limm template, in the same way that a standard 32-bit | |
2469 | instruction is built. This generated limm is then added to the list of | |
2470 | tokens that is passed to the standard instruction encoder, along with | |
2471 | the first list of operands (from the base arc_opcode). | |
2472 | ||
2473 | The first list of operands then, describes how to build the base | |
2474 | instruction, and includes the 32-bit limm that was previously generated | |
2475 | as the last operand. | |
2476 | ||
2477 | In most cases operands are either encoded into the base instruction or | |
2478 | into the limm. When this happens the operand slot will be filled with | |
2479 | an operand identifier in one list, and will be IGNORED in the other | |
2480 | list, this special operand value causes the operand to be ignored, | |
2481 | without being encoded at this point. | |
2482 | ||
2483 | However, in some cases, an operand is split between the base instruction | |
2484 | and the 32-bit limm, in this case the operand slot will be filled in | |
2485 | both operand lists (see mov4b for one example of this). */ | |
