The new Synopsys's ARCv3 ISA is capable to run either 64-bit or 32-bit ISA. The new 32-bit ISA is not compatible with the old Synopsys ARCv1/ARCv2 ISA, however, it retains a lot of common concepts. Thus, this patch is reusing the old ARC BFD backend and adds the necessary bits for the new architecture in a similar way as it is done for RISCV backend. bfd/ xxxx-xx-xx Claudiu Zissulescu <claziss@synopsys.com> Cupertino Miranda <cupertinomiranda@gmail.com> * bfd/Makefile.am: Add ARC64 files. * bfd/Makefile.in: Regerate. * bfd/arc-got.h (TCB_SIZE): Depends on the target architecture. (GOT_ENTRY_SIZE): New define. (write_in_got): Likewise. (read_from_got): Likewise. (align_power): Likewise. (arc_got_entry_type_for_reloc): Use RELA_SIZE and GOT_ENTRY_SIZE. (arc_fill_got_info_for_reloc): Update formating. (relocate_fix_got_relocs_for_got_info): Likewise. (arc_static_sym_data): Deleted structure. (get_static_sym_data): Deleted function. (relocate_fix_got_relocs_for_got_info): Use symbol static data. (create_got_dynrelocs_for_single_entry): Update formating. (create_got_dynrelocs_for_got_info): Likewise. * bfd/arc-plt.c: New file. * bfd/arc-plt.def: Add ARC64 PLT entry. * bfd/arc-plt.h: Clean it up, move functionality to arc-plt.c file. * bfd/archures.c: Add ARC64 target. * bfd/config.bfd: Likewise. * bfd/configure.ac: Likewise. * bfd/bfd-in2.h: Regenerate. * bfd/configure: Likewise. * bfd/libbfd.h: Likewise. * bfd/cpu-arc.c: Clean it up. * bfd/cpu-arc64.c: New file. * bfd/elf32-arc.c: Renamed to elfnn-arc.c. * bfd/elfnn-arc.c: New file. * bfd/reloc.c: Add new ARC64 relocs. * bfd/targets.c: Add ARC64 target.
