(bfd_decode_symclass): Likewise. * elf.c (swap_out_syms): Translate BSF_INDIRECT_FUNCTION into STT_IFUNC. (elf_find_function): Treat STT_IFUNC in the same way as STT_FUNC. (_bfd_elf_is_function_type): Likewise. * elf32-arm.c (arm_elf_find_function): Likewise. (elf32_arm_adjust_dynamic_symbol): Likewise. (elf32_arm_swap_symbol_in): Likewise. (elf32_arm_additional_program_headers): Likewise. * elf32-i386.c (is_indirect_symbol): New function. (elf_i386_check_relocs): Also generate dynamic relocs for relocations against STT_IFUNC symbols. (allocate_dynrelocs): Likewise. (elf_i386_relocate_section): Likewise. * elf64-x86-64.c (is_indirect_symbol): New function. (elf64_x86_64_check_relocs): Also generate dynamic relocs for relocations against STT_IFUNC symbols. (allocate_dynrelocs): Likewise. (elf64_x86_64_relocate_section): Likewise. * elfcode.h (elf_slurp_symbol_table): Translate STT_IFUNC into BSF_INDIRECT_FUNCTION. * elflink.c (_bfd_elf_adjust_dynamic_reloc_section): Add support for STT_IFUNC symbols. (get_ifunc_reloc_section_name): New function. (_bfd_elf_make_ifunc_reloc_section): New function. * elf-bfd.h (struct bfd_elf_section_data): Add indirect_relocs field. * bfd-in2.h: Regenerate. gas/ * config/obj-elf.c (obj_elf_type): Add support for STT_IFUNC type. * doc/as.texinfo: Document new feature. * NEWS: Mention new feature. gas/testsuite/ * gas/elf/type.s: Add test of STT_IFUNC symbol type. * gas/elf/type.e: Update expected disassembly. * gas/elf/elf.exp: Update grep of symbol types. ld/ * NEWS: Mention new feature. * pe-dll.c (process_def_file): Replace use of redundant BFD_FORT_COMM_DEFAULT_VALUE with 0. * scripttempl/elf.sc: Add .rel.ifunc.dyn and .rela.ifunc.dyn sections. ld/testsuite/ * ld-mips-elf/reloc-1-n32.d: Updated expected output for reloc descriptions. * ld-mips-elf/reloc-1-n64.d: Likewise. * ld-i386/ifunc.d: New test. * ld-i386/ifunc.s: Source file for the new test. * ld-i386/i386.exp: Run the new test. --- elfcpp/ChangeLog | 4 ++++ elfcpp/elfcpp.h | 3 ++- 2 files changed, 6 insertions(+), 1 deletion(-) (limited to 'elfcpp') diff --git a/elfcpp/ChangeLog b/elfcpp/ChangeLog index 949ffeb345..830cd6fb5d 100644 --- a/elfcpp/ChangeLog +++ b/elfcpp/ChangeLog @@ -1,3 +1,7 @@ +2008-12-03 Nick Clifton + + * elfcpp.h (enum STT): Add STT_IFUNC. + 2008-06-12 David S.
