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.
