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.
