Ian Lance Taylor 374d2ef905 Add support for creating shared libraries under i386 ELF and SPARC 
ELF.  Based on patches by Eric Youngdale <ericy@cais.cais.com>.
	* libelf.h (struct elf_link_hash_entry): Remove copy_offset field.
	Add got_offset and plt_offset fields.
	(ELF_LINK_HASH_REF_DYNAMIC_MULTIPLE): Don't define.
	(ELF_LINK_HASH_DEF_DYNAMIC_MULTIPLE): Don't define.
	(ELF_LINK_HASH_NEEDS_COPY): Define.
	(struct elf_backend_data): Add check_relocs field.
	(struct bfd_elf_section_data): Change relocs from PTR to
	Elf_Internal_Rela *.
	(struct elf_obj_tdata): Add local_got_offsets field.
	(elf_local_got_offsets): Define accessor macro.
	(bfd_elf32_link_create_dynamic_sections): Declare.
	(bfd_elf32_link_record_dynamic_symbol): Declare.
	(bfd_elf64_link_create_dynamic_sections): Declare.
	(bfd_elf64_link_record_dynamic_symbol): Declare.
	* elfcode.h (elf_slurp_reloc_table): Don't use the section data
	relocs field.
	(elf_link_record_dynamic_symbol): Make globally visible.  Use
	macro to rename to NAME(bfd_elf,link_record_dynamic_symbol).
	(elf_link_add_object_symbols): If creating a shared library, put
	make all local symbols dynamic.  Don't bother with the
	DYNAMIC_MULTIPLE flags.  Call the check_relocs backend function if
	it is defined.
	(elf_link_create_dynamic_sections): Make globally visible.  Use
	macro to rename to NAME(bfd_elf,link_create_dynamic_sections).  If
	creating a shared library, make sure that _DYNAMIC is added as a
	dynamic symbol.
	(elf_link_read_relocs): New function.
	(NAME(bfd_elf,record_link_assignment)): If creating a shared
	library, always create symbols, and always make them dynamic.
	(elf_bfd_final_link): Permit creation of shared libraries.
	(elf_link_input_bfd): Use elf_link_read_relocs to get the relocs.

	define _GLOBAL_OFFSET_TABLE_ at the start of it.  If creating a
	shared library, make sure that _GLOBAL_OFFSET_TABLE_ is added as a
	dynamic symbol.  Don't create .rel.bss if creating a shared
	library.
	(elf_i386_check_relocs): New function.
	(elf_i386_adjust_dynamic_symbol): Don't make a PLT entry if the
	symbol already has one.  When making a PLT entry, set plt_offset.
	Don't create a copy reloc when creating a shared library.  Don't
	set copy_offset, just set ELF_LINK_HASH_NEEDS_COPY.
	(elf_i386_allocate_dynamic_section): Remove.

	Only mark a PLT symbol as undefined if it was not defined by a
	regular object file.  Create a GOT entry if got_offset is set.
	Create a copy reloc if ELF_LINK_HASH_NEEDS_COPY is set.
	(elf_i386_finish_dynamic_sections): Change the handling of
	DT_RELSZ to simply subtract out the size of .rel.plt.  If creating
	a shared library, produce PIC PLT code.
	(elf_backend_check_relocs): Define.
	* elf32-sparc.c (elf_sparc_howto_table): Change R_SPARC_GOT10,
	R_SPARC_GOT22, and R_SPARC_PC10 to not warn about reloc overflow.
	(elf32_sparc_create_dynamic_sections): If creating a shared

        dynamic symbol, and set the type to STT_OBJECT.  Likewise for
        _PROCEDURE_LINKAGE_TABLE_.  Don't create .rel.bss if creating a
        shared library.

	set copy_offset, just set ELF_LINK_HASH_NEEDS_COPY.
	(elf32_sparc_allocate_dynamic_section): Remove.
