2016-12-03PowerPC64 dot-symbol compatibility bugfixesAlan Modra3-163/+204
Lots of fixes for the compatibility code that handles linking of -mcall-aixdesc code (or that generated by 12 year old gcc) with current ELFv1 ABI code. 1) A reference to a dot-symbol in an object file wasn't satisfied by a function descriptor in later object files. 2) The as-needed code had bit-rotted; Shared libs now need a strong reference to be counted as needed. 3) --gc-sections involving dot-symbols was broken, needing func_desc_adjust to be run early and lots of other fixes. bfd/ * elf64-ppc.c (struct ppc_link_hash_entry): Delete "was_undefined". (struct ppc_link_hash_table): Delete "twiddled_syms". Add "need_func_desc_adj". (lookup_fdh): Link direct fdh sym via oh field and set flags. (make_fdh): Make strong and weak undefined function descriptor symbols. (ppc64_elf_merge_symbol): New function. (elf_backend_merge_symbol): Define. (ppc64_elf_archive_symbol_lookup): Don't test undefweak for fake function descriptors. (add_symbol_adjust): Don't twiddle symbols to undefweak. Propagate more ref flags to function descriptor symbol. Make some function descriptor symbols dynamic. (ppc64_elf_before_check_relocs): Only run add_symbol_adjust for ELFv1. Set need_func_desc_adj. Don't fix undefs list. (ppc64_elf_check_relocs): Set non_ir_ref for descriptors. Don't call lookup_fdh here. (ppc64_elf_gc_sections): New function. (bfd_elf64_bfd_gc_sections): Define. (ppc64_elf_gc_mark_hook): Mark descriptor. (func_desc_adjust): Don't make fake function descriptor syms strong here. Exit earlier on non-dotsyms. Take note of elf.dynamic flag when deciding whether a dynamic function descriptor might be needed. Transfer elf.dynamic and set elf.needs_plt. Move plt regardless of visibility. Make descriptor dynamic if entry sym is dynamic, not for other cases. (ppc64_elf_func_desc_adjust): Don't run func_desc_adjust if already done. (ppc64_elf_edit_opd): Use oh field rather than lookup_fdh. (ppc64_elf_size_stubs): Likewise. (ppc_build_one_stub): Don't clear was_undefined. Only set sym undefweak if stub symbol is defined.

2016-12-02Always pass a valid section header offset to elf_parse_notesGary Benson2-1/+6
_bfd_elf_make_section_from_shdr calls elf_parse_notes with an offset of -1. This argument is used to calculate Elf_Internal_Note.descpos, which ends up set to a positive but meaningless value. This commit updates _bfd_elf_make_section_from_shdr to pass the correct offset to elf_parse_notes, making Elf_Internal_Note.descpos correct in all cases. bfd/ChangeLog: * elf.c (_bfd_elf_make_section_from_shdr): Pass offset to elf_parse_notes.

2016-11-30PR20886, looping in ppc64_elf_size_stubsAlan Modra2-1/+10
The PR20886 binary is large enough that there are two stub sections servicing .text (which is 88M). It so happens that between one iteration of sizing and the next that one stub section grows while the other shrinks. Since one section is always growing, the loop never terminates. This patch changes the algorithm to not update previous size on shrinking, once we go past a certain number of iterations. PR ld/20886 * elf64-ppc.c (ppc64_elf_size_stubs): Make rawsize max size seen on any pass past STUB_SHRINK_ITER.
