  "message": "Use GCC LTO wrapper to get real symbols from LTO IR objects\n\nGCC LTO wrapper is needed to extract real symbols from LTO IR objects.\nThis patch does the following:\n\n1. Set up GCC LTO wrapper for each LTO IR object.\n2. Run GCC LTO wrapper to get the real object.\n3. Extract symbol info from the real object.\n4. Cleanup afterwards.\n\nbfd/\n\n\tPR binutils/25355\n\t* configure.ac (HAVE_EXECUTABLE_SUFFIX): New AC_DEFINE.\n\t(EXECUTABLE_SUFFIX): Likewise.\n\t* config.in: Regenerated.\n\t* configure: Likewise.\n\t* plugin.c (bfd_plugin_close_and_cleanup): Removed.\n\t(plugin_list_entry): Add all_symbols_read, cleanup_handler,\n\tgcc, lto_wrapper, resolution_file, resolution_option, gcc_env,\n\treal_bfd, real_nsyms, real_syms, lto_nsyms and lto_syms.\n\t(get_lto_wrapper): New.\n\t(setup_lto_wrapper_env): Likewise.\n\t(current_plugin): Likewise.\n\t(register_all_symbols_read): Likewise.\n\t(register_cleanup): Likewise.\n\t(get_symbols): Likewise.\n\t(add_input_file): Likewise.\n\t(bfd_plugin_close_and_cleanup): Likewise.\n\t(claim_file): Removed.\n\t(register_claim_file): Set current_plugin-\u003eclaim_file.\n\t(add_symbols): Make a copy of LTO symbols.
