plugin: Use LDPT_ADD_SYMBOLS_V2 to get symbol type
Since LTO plugin may generate more than one ltrans.o file from one input IR object as LTO wrapper ignores -flto-partition=none: lto-wrapper.c:608: 604 /* Drop arguments that we want to take from the link line. */ 605 case OPT_flto_: 606 case OPT_flto: 607 case OPT_flto_partition_: 608 continue; the LTO wrapper approach is not only slow but also unreliable. Since the LTO plugin API has been extended to add LDPT_ADD_SYMBOLS_V2 with symbol type and section kind, we can use LDPT_ADD_SYMBOLS_V2 to get symbol type, instead of invoking the LTO wrapper. PR binutils/25640 * plugin.c (plugin_list_entry): Add has_symbol_type. (add_symbols_v2): New function. (bfd_plugin_open_input): Don't invoke LTO wrapper if LTO plugin provides symbol type. (try_load_plugin): Add LDPT_ADD_SYMBOLS_V2. (bfd_plugin_canonicalize_symtab): Use LTO plugin symbol type if available.
