arc: Add nps400 machine type, and assembler flag.
This commit introduces the nps400 machine type as a variant of arc.
There's a new flag in the assembler to select this machine type. All
other changes are just adding handling of the new machine type into the
relevant places.
The nps400 is an arc700 variant with some vendor specific instructions
added into the instruction set. This commit does not add any of the new
instructions, this is just laying the groundwork for future commits.
However, in preparation for these new instructions a new opcode define for
nps400 has been added to include/opcode/arc.h, this new opcode define is
used in the assembler and disassembler along with the existing define
for arc700 such that when assembling and disassembling for nps400 the
user will have access to all arc700 instructions and all the nps400
vendor extension instructions.
bfd/ChangeLog:
* archures.c (bfd_mach_arc_nps400): Define.
* bfd-in2.h: Regenerate.
* cpu-arc.c (arch_info_struct): New entry for nps400, renumber
some existing entries to make space.
* elf32-arc.c (arc_elf_object_p): Add nps400 case.
(arc_elf_final_write_processing): Likewise.
binutils/ChangeLog:
* readelf.c (decode_ARC_machine_flags): Handle nps400.
gas/ChangeLog:
* config/tc-arc.c (cpu_types): Add nps400 entry.
(check_zol): Handle nps400.
include/ChangeLog:
* elf/arc.h (E_ARC_MACH_NPS400): Define.
* opcode/arc.h (ARC_OPCODE_NPS400): Define.
opcodes/ChangeLog:
* arc-dis.c (print_insn_arc): Handle nps400.
