The link phase is always partial (-r) for VxWorks in kernel mode, which means that it uses incremental LTO linking by default (-flinker-output=rel). But in this mode the LTO plugin outputs a warning if one of the object files involved in the link does not contain LTO bytecode, before switching to nolto-rel mode. We do not do repeated incremental linking for VxWorks so silence the warning. lto-plugin/ * lto-plugin.c: Document -linker-output-auto-notlo-rel option. (linker_output_set): Change type to bool. (linker_output_known): Likewise. (linker_output_auto_nolto_rel): New variable. (all_symbols_read_handler): Take it into account. <LDPO_REL>: Do not issue the warning if it is set. (process_option): Process -linker-output-auto-notlo-rel. (cleanup_handler): Remove unused variable. (onload) <LDPT_LINKER_OUTPUT>: Adjust to above type change. gcc/ * gcc.c (LTO_PLUGIN_SPEC): Define if not already. (LINK_PLUGIN_SPEC): Execute LTO_PLUGIN_SPEC. * config/vxworks.h (LTO_PLUGIN_SPEC): Define. |
