31 configured and built for the 'arc*-mellanox-*-*' target. As far as
32 possible all ARC NPS400 features are built into all ARC target builds as

886a2506 2027/* The opcode table.
0d2bcfaf 2028
886a2506 2029 The format of the opcode table is:
0d2bcfaf 2030
1328504b
AB		 2031 NAME OPCODE MASK CPU CLASS SUBCLASS { OPERANDS } { FLAGS }.
2032
2033 The table is organised such that, where possible, all instructions with
2034 the same mnemonic are together in a block. When the assembler searches
2035 for a suitable instruction the entries are checked in table order, so
2036 more specific, or specialised cases should appear earlier in the table.
2037
2038 As an example, consider two instructions 'add a,b,u6' and 'add
2039 a,b,limm'. The first takes a 6-bit immediate that is encoded within the
2040 32-bit instruction, while the second takes a 32-bit immediate that is
2041 encoded in a follow-on 32-bit, making the total instruction length
2042 64-bits. In this case the u6 variant must appear first in the table, as
2043 all u6 immediates could also be encoded using the 'limm' extension,
2044 however, we want to use the shorter instruction wherever possible.
2045
2046 It is possible though to split instructions with the same mnemonic into
2047 multiple groups. However, the instructions are still checked in table
2048 order, even across groups. The only time that instructions with the
2049 same mnemonic should be split into different groups is when different
2050 variants of the instruction appear in different architectures, in which
2051 case, grouping all instructions from a particular architecture together
2052 might be preferable to merging the instruction into the main instruction
2053 table.
2054
2055 An example of this split instruction groups can be found with the 'sync'
2056 instruction. The core arc architecture provides a 'sync' instruction,
2057 while the nps instruction set extension provides 'sync.rd' and
2058 'sync.wr'. The rd/wr flags are instruction flags, not part of the
2059 mnemonic, so we end up with two groups for the sync instruction, the
2060 first within the core arc instruction table, and the second within the
2061 nps extension instructions. */

2355/* The following instructions are all either 48 or 64 bits long, and
2356 require special handling in the assembler and disassembler.
2357
2358 The first part of each ARC_LONG_OPCODE is the base ARC_OPCODE, this is
2359 either the 16 or 32 bit base instruction, and its opcode list will
2360 always end in a LIMM.
2361
2362 The rest of the ARC_LONG_OPCODE describes how to build the LIMM from the
2363 instruction operands. There are therefore two lists of operands for
2364 each ARC_LONG_OPCODE, the second list contains operands that are merged
2365 into the limm template, in the same way that a standard 32-bit
2366 instruction is built. This generated limm is then added to the list of
2367 tokens that is passed to the standard instruction encoder, along with
2368 the first list of operands (from the base arc_opcode).
2369
2370 The first list of operands then, describes how to build the base
2371 instruction, and includes the 32-bit limm that was previously generated
2372 as the last operand.
2373
2374 In most cases operands are either encoded into the base instruction or
2375 into the limm. When this happens the operand slot will be filled with
2376 an operand identifier in one list, and will be IGNORED in the other
2377 list, this special operand value causes the operand to be ignored,
2378 without being encoded at this point.
2379
2380 However, in some cases, an operand is split between the base instruction
2381 and the 32-bit limm, in this case the operand slot will be filled in
2382 both operand lists (see mov4b for one example of this). */
