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/elf64-sparc.c | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) (limited to 'bfd/elf64-sparc.c') diff --git a/bfd/elf64-sparc.c b/bfd/elf64-sparc.c index 18bdfb4..a1bde20 100644 --- a/bfd/elf64-sparc.c +++ b/bfd/elf64-sparc.c @@ -424,6 +424,9 @@ elf64_sparc_add_symbol_hook (bfd *abfd, struct bfd_link_info *info, { static const char *const stt_types[] = { "NOTYPE", "OBJECT", "FUNCTION" }; + if (ELF_ST_TYPE (sym->st_info) == STT_GNU_IFUNC) + elf_tdata (info->output_bfd)->has_ifunc_symbols = TRUE; + if (ELF_ST_TYPE (sym->st_info) == STT_REGISTER) { int reg; @@ -856,6 +859,8 @@ const struct elf_size_info elf64_sparc_size_info = _bfd_sparc_elf_plt_sym_val #define bfd_elf64_bfd_link_hash_table_create \ _bfd_sparc_elf_link_hash_table_create +#define bfd_elf64_bfd_link_hash_table_free \ + _bfd_sparc_elf_link_hash_table_free #define elf_info_to_howto \ _bfd_sparc_elf_info_to_howto #define elf_backend_copy_indirect_symbol \ @@ -910,6 +915,8 @@ const struct elf_size_info elf64_sparc_size_info = /* Section 5.2.4 of the ABI specifies a 256-byte boundary for the table. */ #define elf_backend_plt_alignment 8 +#define elf_backend_post_process_headers _bfd_elf_set_osabi + #include "elf64-target.h" /* FreeBSD support */ @@ -920,8 +927,6 @@ const struct elf_size_info elf64_sparc_size_info = #undef ELF_OSABI #define ELF_OSABI ELFOSABI_FREEBSD -#undef elf_backend_post_process_headers -#define elf_backend_post_process_headers _bfd_elf_set_osabi #undef elf64_bed #define elf64_bed elf64_sparc_fbsd_bed -- cgit v1.1
