The master branch has been updated by Alan Modra <amodra@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=aa465b19c80b660b4d4fe6608fb66ebeb469f38b commit aa465b19c80b660b4d4fe6608fb66ebeb469f38b Author: Alan Modra <amodra@gmail.com> Date: Wed Oct 2 10:41:01 2019 +0930 [GOLD] OSABI not set when STT_GNU_IFUNC or STB_GNU_UNIQUE symbols output This patch arranges to have OSABI set to ELFOSABI_GNU (if not set to some other non-zero value) when gold outputs an ifunc local or global symbol, or a unique global symbol to either .dynsym or .symtab. STT_GNU_IFUNC and STB_GNU_UNIQUE have values in the LOOS to HIOS range and therefore require interpretation according to OSABI. I'm not sure why parameters->target() is const Target& while parameters->sized_target() is Sized_target*, but it's inconvenient to use the latter in Symbol_table::finalize. So this patch adds another const_cast complained about in layout.cc and gold.cc. PR 24853 * symtab.h (set_has_gnu_output, has_gnu_output_): New. * symtab.cc (Symbol_table::Symbol_table): Init has_gnu_output_. (Symbol_table::finalize): Set ELFOSABI_GNU when has_gnu_output_. (Symbol_table::set_dynsym_indexes, Symbol_table::sized_finalize): Call set_has_gnu_output for STT_GNU_IFUNC and STB_GNU_UNIQUE globals. * object.cc (Sized_relobj_file::do_finalize_local_symbols): Call set_has_gnu_output when STT_GNU_IFUNC locals will be output.
