	for sections that the linker didn't create.
	(ppc_elf_finish_dynamic_sections): Only try to write out a section
	symbol if it was created in ppc_elf_size_dynamic_sections.
	(ppc_elf_relocate_section): Complain if we have to generate a reloc
	relative to a section for which we didn't output a symbol.

	* elf32-ppc.c (ppc_elf_size_dynamic_sections): Clean up.  PLT
	relocs are 'rela' relocs, like everything else.  .rela.plt is not
	a read-only section, so we don't have to special-case it.

	.rela.bss section are (of course) 'rela' relocs not 'rel' relocs.

	actual .got section.

	words start from the symbol '_GLOBAL_OFFSET_TABLE_'.

	ourselves.
	(ppc_elf_finish_dynamic_symbol): Set up GOT relocations when a
	symbol has a GOT entry.
	(ppc_elf_relocate_section): Record when a symbol is used through
	the GOT, and allocate space in the GOT for each such symbol.
	(ppc_elf_adjust_dynamic_symbol): Delete unused .got.plt stuff.
	(ppc_elf_create_linker_section): Delete unused LINKER_SECTION_GOT
	stuff.

	* elf32-ppc.c (ppc_elf_howto_raw): GOT16_HA relocs should be
	treated in a similar way to ADDR16_HA relocs.
	(ppc_elf_relocate_section): PLTREL24 relocs do not get copied into
	shared objects; the linker must deal with them.
	(ppc_elf_create_linker_section): Stop setting
	_GLOBAL_OFFSET_TABLE_ to the wrong value; delete unused
	LINKER_SECTION_PLT stuff.
	(ppc_elf_check_relocs): Delete unused LINKER_SECTION_PLT stuff.
	(ppc_elf_finish_dynamic_sections): Use BFD calls to get GOT
	section, not ELF-specific calls.
	(elf_backend_plt_not_loaded): Set to 1.
	(elf_backend_got_symbol_offset): Set to 4.
	* elf-bfd.h (elf_backend_data): Add 'plt_not_loaded' member
	for when ld.so fills in the PLT; and 'got_symbol_offset' member.
	* elflink.c (_bfd_elf_create_dynamic_sections): Apply
	plt_not_loaded member.
	(_bfd_elf_create_got_section): Apply got_symbol_offset.
	* elfxx-target.h (elf_backend_plt_not_loaded): Set default to
	'loaded'.
	(elf_backend_G_O_T_offset): Set default to 0.
	(elfNN_bed): Set added fields.

	* elf32-ppc.c (ppc_elf_size_dynamic_sections): Was setting
	DT_RELENT in shared objects; should be DT_RELAENT.

	* elf32-ppc.c (ppc_elf_relocate_section): Propagate
	R_PPC_ADDR16_HA relocs to shared objects. Cope with case where
	such a reloc (in a non-shared object) refers to a symbol that's
	not defined.

Mon Jun 16 14:42:14 1997  H.J. Lu  <[e-mail]>

	* elf64-mips.c (mips_elf64_swap_reloca_in): Use
	bfd_h_get_signed_64 to set the r_addend field.

	elf_link_assign_sym_version before elf_adjust_dynamic_symbol.
	(elf_fix_symbol_flags): New static function, broken out of
	elf_adjust_dynamic_symbol.
	(elf_adjust_dynamic_symbol): Call elf_fix_symbol_flags.
	(elf_link_assign_sym_version): Likewise.  Permit a symbol to be
	forced local even if NEEDS_PLT is set.  When forcing a symbol to
	be local, clear NEEDS_PLT.
	(elf_link_output_extsym): Remove unused local bed.

Wed Jun 11 22:44:20 1997  Jeffrey A Law  ([e-mail])

	* elf32-mn10300.c (elf32_mn10300_link_hash_entry): New structure

	relocation value for a GOT reloc for a symbol which is turning
	into a local symbol.

	local symbol, write out a RELATIVE reloc rather than a GLOB_DAT
	reloc.
