newlib/include/elf/sparc.h
David S. Miller 95fc66f6cb include/ 
* elf/sparc.h (R_SPARC_JMP_IREL, R_SPARC_IRELATIVE): Define.

bfd/

	* reloc.c (BFD_RELOC_SPARC_JMP_IREL): New.
	(BFD_RELOC_SPARC_IRELATIVE): Likewise.
	* bfd-in2.h: Regenerate.
	* libbfd.h: Regenerate.

	* elfxx-sparc.h (_bfd_sparc_elf_link_hash_table): Add loc_hash_table
	and loc_hash_memory.
	(_bfd_sparc_elf_link_hash_table_free): Declare.
	* elf32-sparc.c (elf32_sparc_add_symbol_hook): New.
	(elf_backend_add_symbol_hook, elf_backend_post_process_headers,
	bfd_elf32_bfd_link_hash_table_free): Define.
	* elf64-sparc.c (elf64_sparc_add_symbol_hook): Set
	has_ifunc_symbols if STT_GNU_IFUNC.
	(bfd_elf64_bfd_link_hash_table_free): Define.
	(elf_backend_post_process_headers): Define always.
	* elfxx-sparc.c (sparc_jmp_irel_howto, sparc_irelative_howto): New.
	(sparc_reloc_map): Add entries for new IFUNC relocs.
	(_bfd_sparc_elf_reloc_type_lookup): Handle new IFUNC relocs.
	(_bfd_sparc_elf_info_to_howto_ptr): Likewise.
	(elf_sparc_local_htab_hash, elf_sparc_local_htab_eq,
	elf_sparc_get_local_sym_hash): New.
	(_bfd_sparc_elf_create_dynamic_sections): Move PLT ops initialization
	from here...
	(_bfd_sparc_elf_link_hash_table_create): ... to here.  Allocate
	local hash table.
	(_bfd_sparc_elf_link_hash_table_free): New.
	(create_ifunc_sections): New.
	(_bfd_sparc_elf_check_relocs): Unconditionally assign htab->elf.dynobj
	and call create_ifunc_sections().  For local STT_GNU_IFUNC symbols
	cons up a fake local hash table entry for it.  Unconditionally add
	a PLT refcount for STT_GNU_IFUNC symbols when h->def_regular.  Count
	dyn relocs for ifunc.
	(_bfd_sparc_elf_adjust_dynamic_symbol): Handle ifunc.
	(allocate_dynrelocs):  Unconditionally emit a PLT entry when STT_GNU_IFUNC
	and h->def_regular.  Count GOT dyn relocs for ifunc.
	(allocate_local_dynrelocs): New function.
	(_bfd_sparc_elf_size_dynamic_sections): Invoke it over the local hash table.
	Emit dynamic relocs to irelplt when not shared.  Treat iplt like splt.
	(_bfd_sparc_elf_relocate_section): Handle ifunc relocations by hand.
	(_bfd_sparc_elf_finish_dynamic_symbol): Adjust for non-dynamic ifunc plt
	in iplt/irelplt.

ld/testsuite/

	* ld-ifunc/ifunc.exp: Run for sparc.
