bfd/ChangeLog: * arc-plt.def: New file. * arc-plt.h: Likewise. * elf32-arc.c (elf_arc_abs_plt0_entry, elf_arc_abs_pltn_entry, elf_arcV2_abs_plt0_entry, elf_arcV2_abs_pltn_entry, elf_arc_pic_plt0_entry, elf_arc_pic_pltn_entry, elf_arcV2_pic_plt0_entry, elf_arcV2_pic_pltn_entry): Remove. (name_for_global_symbol): Added. (ADD_RELA): Helper to create dynamic relocs. (new_got_entry_to_list): Create a new got entry in linked list. (symbol_has_entry_of_type): Search for specific type of entry in list. (is_reloc_for_GOT): return FALSE for any TLS related relocs. (is_reloc_for_TLS, arc_elf_set_private_flags) (arc_elf_print_private_bfd_data, arc_elf_copy_private_bfd_data) (arc_elf_merge_private_bfd_data): New functions. (debug_arc_reloc): Cleaned debug info printing. (PDATA reloc): Changed not to perform address alignment. (reverse_me): Added. Fix for ARC_32 relocs.

Changed function to access an array of list of GOT entries instead of just an array of offsets. (elf_arc_relocate_section): Added support for PIC and TLS related relocations. (elf_arc_check_relocs): Likewise. (elf_arc_adjust_dynamic_symbol, elf_arc_finish_dynamic_symbol, (elf_arc_finish_dynamic_sections): Likewise (arc_create_dynamic_sections): Modified conditions to create dynamic sections. (ADD_SYMBOL_REF_SEC_AND_RELOC): New macro. (plt_do_relocs_for_symbol, relocate_plt_for_symbol) (relocate_plt_for_entry): Changed to support new way to define PLT related code. (add_symbol_to_plt): Likewise.
