541a4b5425 * elflink.h (elf_merge_symbol): In the case of a new defined
symbol overriding an old defined symbol, return the hash table
	entry which we modify, even if it is the target of an
	indirection.
	(elf_link_add_object_symbols): If the real name of the symbol gets
	overridden, convert the versioned symbol into an indirect symbol
	to the real symbol.

* elf32-ppc.c (ppc_elf_relocate_section): Don't emit R_PPC_REL*
 	relocs in shared libraries which refer to local symbols.  Cope
 	with addend when processing a GOT relocation.

	* elf32-ppc.c (ppc_elf_size_dynamic_sections): Only create symbols
	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.

	* elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Entries in the
	.rela.bss section are (of course) 'rela' relocs not 'rel' relocs.

	* elf32-ppc.c (ppc_elf_check_relocs): Initialise srelgot.
	(ppc_elf_relocate_section): @got offsets are 4 from start of the
	actual .got section.
	* elflink.c (_bfd_elf_create_got_section): The three reserved
	words start from the symbol '_GLOBAL_OFFSET_TABLE_'.

	* elf32-ppc.c (ppc_elf_size_dynamic_sections): '.rela' is 5
	characters, not 4.

	* elf32-ppc.c (ppc_elf_check_relocs): Use
	_bfd_elf_create_got_section to create the GOT rather than
	ppc_elf_create_linker_section. Create the '.rela.got' section
	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.

Ian Lance Taylor
90d7b9b9dd * elf32-i386.c (elf_i386_relocate_section): When generating a
shared library, do the relocation if the input section is not
	allocated in memory.
