Will Newton 1419bbe571 aarch64: Add support for GNU indirect functions. ... 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: 2013-10-03 Will Newton <will.newton@linaro.org> * configure: Regenerate. * configure.in: Build elf-ifunc.o for AArch64. * elfnn-aarch64.c: Include objalloc.h. (elfNN_aarch64_local_htab_hash): New function. (elfNN_aarch64_local_htab_eq): New function. (elfNN_aarch64_get_local_sym_hash): New function. (elfNN_aarch64_link_hash_table_create): Initialize local STT_GNU_IFUNC symbol hash. (elfNN_aarch64_hash_table_free): Free local STT_GNU_IFUNC symbol hash. (elfNN_aarch64_final_link_relocate): Add sym argument. Add support for handling STT_GNU_IFUNC symbols. (elfNN_aarch64_gc_sweep_hook): Add support for garbage collecting references to STT_GNU_IFUNC symbols. (elfNN_aarch64_adjust_dynamic_symbol): Add support for handling STT_GNU_IFUNC symbols. (elfNN_aarch64_check_relocs): Add support for handling STT_GNU_IFUNC symbols. Ensure we don't increase plt.refcount from -1 to 0. (elfNN_aarch64_post_process_headers): Call _bfd_elf_set_osabi. (elfNN_aarch64_is_function_type): Remove function. (elfNN_aarch64_allocate_dynrelocs): Handle STT_GNU_IFUNC symbols. (elfNN_aarch64_allocate_ifunc_dynrelocs): New function. (elfNN_aarch64_allocate_local_dynrelocs): New function. (elfNN_aarch64_allocate_local_ifunc_dynrelocs): New function. (elfNN_aarch64_size_dynamic_sections): Call elfNN_aarch64_allocate_local_dynrelocs. (elfNN_aarch64_create_small_pltn_entry): Add info argument. Add support for creating .iplt entries for STT_GNU_IFUNC symbols. (elfNN_aarch64_finish_dynamic_symbol): Add support for handling STT_GNU_IFUNC symbols and .iplt. (elfNN_aarch64_finish_local_dynamic_symbol): New function. (elfNN_aarch64_finish_dynamic_sections): Call elfNN_aarch64_finish_local_dynamic_symbol. ld/ChangeLog: 2013-10-03 Will Newton <will.newton@linaro.org> * emulparams/aarch64elf.sh: Add IREL_IN_PLT. * emulparams/aarch64elf32.sh: Likewise. ld/testsuite/ChangeLog: 2013-10-03 Will Newton <will.newton@linaro.org> * ld-ifunc/ifunc.exp: Enable ifunc tests for AArch64. * ld-aarch64/aarch64-elf.exp: Run ifunc tests. * ld-aarch64/ifunc-1-local.d: New file. * ld-aarch64/ifunc-1-local.s: Likewise. * ld-aarch64/ifunc-1.d: Likewise. * ld-aarch64/ifunc-1.s: Likewise. * ld-aarch64/ifunc-10.d: Likewise. * ld-aarch64/ifunc-10.s: Likewise. * ld-aarch64/ifunc-11.d: Likewise. * ld-aarch64/ifunc-11.s: Likewise. * ld-aarch64/ifunc-12.d: Likewise. * ld-aarch64/ifunc-12.s: Likewise. * ld-aarch64/ifunc-13.d: Likewise. * ld-aarch64/ifunc-13a.s: Likewise. * ld-aarch64/ifunc-13b.s: Likewise. * ld-aarch64/ifunc-14a.d: Likewise. * ld-aarch64/ifunc-14a.s: Likewise. * ld-aarch64/ifunc-14b.d: Likewise. * ld-aarch64/ifunc-14b.s: Likewise. * ld-aarch64/ifunc-14c.d: Likewise. * ld-aarch64/ifunc-14c.s: Likewise. * ld-aarch64/ifunc-14d.d: Likewise. * ld-aarch64/ifunc-14e.d: Likewise. * ld-aarch64/ifunc-14f.d: Likewise. * ld-aarch64/ifunc-15.d: Likewise. * ld-aarch64/ifunc-15.s: Likewise. * ld-aarch64/ifunc-16.d: Likewise. * ld-aarch64/ifunc-16.s: Likewise. * ld-aarch64/ifunc-17a.d: Likewise. * ld-aarch64/ifunc-17a.s: Likewise. * ld-aarch64/ifunc-17b.d: Likewise. * ld-aarch64/ifunc-17b.s: Likewise. * ld-aarch64/ifunc-18a.d: Likewise. * ld-aarch64/ifunc-18a.s: Likewise. * ld-aarch64/ifunc-18b.d: Likewise. * ld-aarch64/ifunc-18b.s: Likewise. * ld-aarch64/ifunc-19a.d: Likewise. * ld-aarch64/ifunc-19a.s: Likewise. * ld-aarch64/ifunc-19b.d: Likewise. * ld-aarch64/ifunc-19b.s: Likewise. * ld-aarch64/ifunc-2-local.d: Likewise. * ld-aarch64/ifunc-2-local.s: Likewise. * ld-aarch64/ifunc-2.d: Likewise. * ld-aarch64/ifunc-2.s: Likewise. * ld-aarch64/ifunc-20.d: Likewise. * ld-aarch64/ifunc-20.s: Likewise. * ld-aarch64/ifunc-3.s: Likewise. * ld-aarch64/ifunc-3a.d: Likewise. * ld-aarch64/ifunc-3b.d: Likewise. * ld-aarch64/ifunc-4.d: Likewise. * ld-aarch64/ifunc-4.s: Likewise. * ld-aarch64/ifunc-4a.d: Likewise. * ld-aarch64/ifunc-5-local.s: Likewise. * ld-aarch64/ifunc-5.s: Likewise. * ld-aarch64/ifunc-5a-local.d: Likewise. * ld-aarch64/ifunc-5a.d: Likewise. * ld-aarch64/ifunc-5b-local.d: Likewise. * ld-aarch64/ifunc-5b.d: Likewise. * ld-aarch64/ifunc-5r-local.d: Likewise. * ld-aarch64/ifunc-6.s: Likewise. * ld-aarch64/ifunc-6a.d: Likewise. * ld-aarch64/ifunc-6b.d: Likewise. * ld-aarch64/ifunc-7.s: Likewise. * ld-aarch64/ifunc-7a.d: Likewise. * ld-aarch64/ifunc-7b.d: Likewise. * ld-aarch64/ifunc-7c.d: Likewise. * ld-aarch64/ifunc-8.d: Likewise. * ld-aarch64/ifunc-8a.s: Likewise. * ld-aarch64/ifunc-8b.s: Likewise. * ld-aarch64/ifunc-9.d: Likewise. * ld-aarch64/ifunc-9.s: Likewise.		2013-10-03 14:46:09 +00:00
