Add support for STT_GNU_IFUNC symbols to the AArch64 bfd backend. The tests are ported from the ld-ifunc tests but are enabled for cross builds so can be run easily without hardware or a simulator. bfd/ChangeLog: 2013-06-07 Will Newton <will.newton@linaro.org> * configure: Regenerate. * configure.in: Build elf-ifunc.o for AArch64. * elf64-aarch64.c: Include objalloc.h. (elf64_aarch64_howto_dynrelocs): Add R_AARCH64_IRELATIVE howto. (struct elf64_aarch64_link_hash_table): Add members for handling R_AARCH64_IRELATIVE relocations. (elf_aarch64_local_htab_hash): New function. (elf_aarch64_local_htab_eq): New function. (elf_aarch64_get_local_sym_hash): New function.

(elf64_aarch64_final_link_relocate): Add sym argument. Add support for handling STT_GNU_IFUNC symbols. (elf64_aarch64_gc_sweep_hook): Add support for garbage collecting references to STT_GNU_IFUNC symbols. (elf64_aarch64_adjust_dynamic_symbol): Add support for handling STT_GNU_IFUNC symbols. (elf64_aarch64_check_relocs): Add support for handling STT_GNU_IFUNC symbols. Ensure we don't increase plt.refcount from -1 to 0. (elf64_aarch64_post_process_headers): Call _bfd_elf_set_osabi. (elf64_aarch64_is_function_type): Remove function. (elf64_aarch64_allocate_dynrelocs): Call _bfd_elf_allocate_ifunc_dyn_relocs for STT_GNU_IFUNC symbols. (elf_aarch64_allocate_local_dynrelocs): New function. (elf64_aarch64_size_dynamic_sections): Call elf_aarch64_allocate_local_dynrelocs. Initialize next_irelative_index. (elf64_aarch64_create_small_pltn_entry): Add info argument. Add support for creating .iplt entries for STT_GNU_IFUNC symbols. (elf64_aarch64_finish_dynamic_symbol): Add support for handling STT_GNU_IFUNC symbols and .iplt. (elf_aarch64_finish_local_dynamic_symbol): New function. (elf64_aarch64_finish_dynamic_sections): Call elf_aarch64_finish_local_dynamic_symbol.
