	* elf64-ppc.h (ppc64_elf_toc): Delete.
	(ppc64_elf_set_toc): Declare.
	* elf64-ppc.c (ppc64_elf_toc_reloc): Replace call to ppc64_elf_toc
	with call the ppc64_elf_set_toc.
	(ppc64_elf_toc_ha_reloc, ppc64_elf_toc64_reloc): Likewise.
	(ppc64_elf_start_multitoc_partition): Likewise.
	(struct ppc_link_hash_table): Delete dot_toc_dot.  Replace all uses
	with elf.hgot.
	(ppc64_elf_process_dot_syms): Don't make a fake function descriptor
	for ".TOC.".
	(ppc64_elf_check_relocs): Mark sections with a reference to .TOC.
	as needing a toc pointer.
	(ppc64_elf_size_stubs): Don't set dot_toc_dot here.
	(ppc64_elf_set_toc): Rename from ppc64_elf_toc.  Add info param.
	Set elf.hgot value.
ld/
	* emultempl/ppc64elf.em: (ppc_layout_sections_again): Call
	ppc64_elf_set_toc rather than ppc64_elf_toc/_bfd_set_gp_value.
	(gld${EMULATION_NAME}_after_allocation): Likewise.
