Add PIC and TLS support to the ARC target.
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.
(arc_do_relocation): Return bfd_reloc_of when no relocation should
occur.
(arc_get_local_got_ents): Renamed from arc_get_local_got_offsets.
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.
(arc_elf_link_hash_table_create): New function.
include/ChangeLog:
* elf/arc-reloc.def (ARC_32, ARC_GOTPC, ARC_TLS_GD_GOT)
(ARC_TLS_IE_GOT, ARC_TLS_DTPOFF, ARC_TLS_DTPOFF_S9, ARC_TLS_LE_S9)
(ARC_TLS_LE_32): Fixed formula.
(ARC_TLS_GD_LD): Use new special function.
* opcode/arc-func.h: Changed all the replacement
functions to clear the patching bits before doing an or it with the value
argument.
