	* bfd-in2.h: Regenerate.
	* elf64-ppc.c (TP_OFFSET, DTP_OFFSET): Declare.
	(ppc64_elf_howto_raw): Add TLS howto's.  Adjust R_PPC64_NONE to be
	against a 32 bit field.
	(ppc64_elf_reloc_type_lookup): Handle TLS relocs.
	(_ppc64_elf_section_data): Add t_symndx and comments.
	(ppc64_elf_section_data): Use elf_section_data macro.
	(ppc64_elf_new_section_hook): American spelling.
	(struct got_entry, struct plt_entry): New.
	(MUST_BE_DYN_RELOC): Rename from IS_ABSOLUTE_RELOC.
	(struct ppc_stub_hash_entry): Add "addend" field.
	(struct ppc_link_hash_entry): Add "tls_type".
	(TLS_TLS, TLS_GD_LD, TLS_LD, TLS_TPREL, TLS_DTPREL,
	TLS_EXPLICIT): Define.
	(struct ppc_link_hash_table): Add tls_sec, tls_get_addr, tlsld_got.
	(link_hash_newfunc): Init new fields.
	(ppc64_elf_link_hash_table_create): Likewise.  Set init_relcount and
	init_offset to NULL.
	(ppc64_elf_copy_indirect_symbol): Copy got and plt info.  Don't call
	_bfd_elf_link_hash_copy_indirect, rather insert relevant code from
	there.
	(update_local_sym_info, update_plt_info): New functions.
	(ppc64_elf_check_relocs): Use them.  Handle TLS relocs.  Adjust GOT
	handling to use got.glist rather than got.refcount.  Likewise for PLT.
	(ppc64_elf_gc_sweep_hook): Handle TLS relocs, new GOT and PLT lists.
	(func_desc_adjust): Adjust for new PLT list.
	(ppc64_elf_adjust_dynamic_symbol): Likewise.
	(get_sym_h, get_tls_type): New functions.
	(ppc64_elf_edit_opd): Remove unused variable.  Use get_sym_h.
	(ppc64_elf_tls_optimize): New function.
	(allocate_dynrelocs): Adjust for new PLT and GOT lists.  Allocate
	TLS relocs.
	(ppc64_elf_size_dynamic_sections): Likewise.
	(ppc_type_of_stub): Adjust for new PLT list.
	(ppc_build_one_stub): Likewise.
	(ppc64_elf_size_stubs): Likewise.  Use get_sym_h.  Treat __tls_get_addr
	calls specially.
	(ppc64_elf_relocate_section): Adjust for new GOT and PLT lists.  Handle
	TLS relocs.  Report local syms using bfd_elf_local_sym_name.  Don't
	init GOT entries that have a reloc.  Generate GOT relocs here..
	(ppc64_elf_finish_dynamic_symbol): ..not here.  Adjust for PLT list.
	* elf64-ppc.h (ppc64_elf_tls_optimize): Declare.
