From d0c9aeb3fc18f9f77a8e173b1fb9616931f669bd Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 8 Feb 2010 20:28:43 +0000 Subject: 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. --- bfd/elfxx-sparc.h | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'bfd/elfxx-sparc.h') diff --git a/bfd/elfxx-sparc.h b/bfd/elfxx-sparc.h index a20855a990f..36748ec0751 100644 --- a/bfd/elfxx-sparc.h +++ b/bfd/elfxx-sparc.h @@ -59,6 +59,10 @@ struct _bfd_sparc_elf_link_hash_table /* Small local sym cache. */ struct sym_cache sym_cache; + /* Used by local STT_GNU_IFUNC symbols. */ + htab_t loc_hash_table; + void *loc_hash_memory; + /* True if the target system is VxWorks. */ int is_vxworks; @@ -102,6 +106,8 @@ extern bfd_boolean _bfd_sparc_elf_mkobject (bfd *); extern struct bfd_link_hash_table *_bfd_sparc_elf_link_hash_table_create (bfd *); +extern void _bfd_sparc_elf_link_hash_table_free + (struct bfd_link_hash_table *); extern bfd_boolean _bfd_sparc_elf_create_dynamic_sections (bfd *, struct bfd_link_info *); extern void _bfd_sparc_elf_copy_indirect_symbol -- cgit v1.2.1
