The Nios II target is deprecated since v8.2 in commit 9997771bc1
("target/nios2: Deprecate the Nios II architecture").
Remove:
- Buildsys / CI infra
- User emulation
- System emulation (10m50-ghrd & nios2-generic-nommu machines)
- Tests

-/* This structure holds information for a particular instruction.
-
- The args field is a string describing the operands. The following
- letters can appear in the args:
- c - a 5-bit control register index
- d - a 5-bit destination register index
- s - a 5-bit left source register index
- t - a 5-bit right source register index
- D - a 3-bit encoded destination register
- S - a 3-bit encoded left source register
- T - a 3-bit encoded right source register
- i - a 16-bit signed immediate
- j - a 5-bit unsigned immediate
- k - a (second) 5-bit unsigned immediate
- l - a 8-bit custom instruction constant
- m - a 26-bit unsigned immediate
- o - a 16-bit signed pc-relative offset
- u - a 16-bit unsigned immediate
- I - a 12-bit signed immediate
- M - a 6-bit unsigned immediate
- N - a 6-bit unsigned immediate with 2-bit shift
- O - a 10-bit signed pc-relative offset with 1-bit shift
- P - a 7-bit signed pc-relative offset with 1-bit shift
- U - a 7-bit unsigned immediate with 2-bit shift
- V - a 5-bit unsigned immediate with 2-bit shift
- W - a 4-bit unsigned immediate with 2-bit shift
- X - a 4-bit unsigned immediate with 1-bit shift
- Y - a 4-bit unsigned immediate
- e - an immediate coded as an enumeration for addi.n/subi.n
- f - an immediate coded as an enumeration for slli.n/srli.n
- g - an immediate coded as an enumeration for andi.n
- h - an immediate coded as an enumeration for movi.n
- R - a reglist for ldwm/stwm or push.n/pop.n
- B - a base register specifier and option list for ldwm/stwm
- Literal ',', '(', and ')' characters may also appear in the args as
- delimiters.
-
- Note that the args describe the semantics and assembly-language syntax
- of the operands, not their encoding into the instruction word.
-
- The pinfo field is INSN_MACRO for a macro. Otherwise, it is a collection
- of bits describing the instruction, notably any relevant hazard
- information.
-
- When assembling, the match field contains the opcode template, which
- is modified by the arguments to produce the actual opcode
- that is emitted. If pinfo is INSN_MACRO, then this is 0.
-
- If pinfo is INSN_MACRO, the mask field stores the macro identifier.
- Otherwise this is a bit mask for the relevant portions of the opcode
- when disassembling. If the actual opcode anded with the match field
- equals the opcode field, then we have found the correct instruction. */
