1936 /* The opcode table.
1937
1938 The format of the opcode table is:
1939
1940 NAME OPCODE MASK CPU CLASS SUBCLASS { OPERANDS } { FLAGS }.
1941
1942 The table is organised such that, where possible, all instructions with
1943 the same mnemonic are together in a block. When the assembler searches
1944 for a suitable instruction the entries are checked in table order, so
1945 more specific, or specialised cases should appear earlier in the table.
1946
1947 As an example, consider two instructions 'add a,b,u6' and 'add
1948 a,b,limm'. The first takes a 6-bit immediate that is encoded within the
1949 32-bit instruction, while the second takes a 32-bit immediate that is
1950 encoded in a follow-on 32-bit, making the total instruction length
1951 64-bits. In this case the u6 variant must appear first in the table, as
1952 all u6 immediates could also be encoded using the 'limm' extension,
1953 however, we want to use the shorter instruction wherever possible.
1954
1955 It is possible though to split instructions with the same mnemonic into
1956 multiple groups. However, the instructions are still checked in table
1957 order, even across groups. The only time that instructions with the
1958 same mnemonic should be split into different groups is when different
1959 variants of the instruction appear in different architectures, in which
1960 case, grouping all instructions from a particular architecture together
1961 might be preferable to merging the instruction into the main instruction
1962 table.
1963
1964 An example of this split instruction groups can be found with the 'sync'
1965 instruction. The core arc architecture provides a 'sync' instruction,
1966 while the nps instruction set extension provides 'sync.rd' and
1967 'sync.wr'. The rd/wr flags are instruction flags, not part of the
1968 mnemonic, so we end up with two groups for the sync instruction, the
1969 first within the core arc instruction table, and the second within the
1970 nps extension instructions. */

2266
2267 The first part of each ARC_LONG_OPCODE is the base ARC_OPCODE, this is
2268 either the 16 or 32 bit base instruction, and its opcode list will
2269 always end in a LIMM.
2270
2271 The rest of the ARC_LONG_OPCODE describes how to build the LIMM from the
2272 instruction operands. There are therefore two lists of operands for
2273 each ARC_LONG_OPCODE, the second list contains operands that are merged
2274 into the limm template, in the same way that a standard 32-bit
2275 instruction is built. This generated limm is then added to the list of
2276 tokens that is passed to the standard instruction encoder, along with
2277 the first list of operands (from the base arc_opcode).
2278
2279 The first list of operands then, describes how to build the base
2280 instruction, and includes the 32-bit limm that was previously generated
2281 as the last operand.
2282
2283 In most cases operands are either encoded into the base instruction or
2284 into the limm. When this happens the operand slot will be filled with
2285 an operand identifier in one list, and will be IGNORED in the other
2286 list, this special operand value causes the operand to be ignored,
2287 without being encoded at this point.
2288
2289 However, in some cases, an operand is split between the base instruction
2290 and the 32-bit limm, in this case the operand slot will be filled in
2291 both operand lists (see mov4b for one example of this). */
