+       * gcc.c (spec_host_machine, accel_dir_suffix): New variables.
+       (process_command): Tweak path construction for the possibility
+       of being configured as an offload compiler.
+       (driver::maybe_putenv_OFFLOAD_TARGETS): New function.
+       (driver::main): Call maybe_putenv_OFFLOAD_TARGETS.
+       (driver::set_up_specs): Tweak path construction for the possibility of
+       being configured as an offload compiler.
+       * lto-wrapper.c (OFFLOAD_TARGET_NAMES_ENV): Define.
+       (offload_names, offloadbegin, offloadend): New static variables.
+       (free_array_of_ptrs, parse_env_var, access_check, compile_offload_image)
+       (compile_images_for_offload_targets, copy_file, find_offloadbeginend):
+       New static functions.
+       (run_gcc): Determine whether offload sections are present.  If so, run
+       compile_images_for_offload_targets and return the names of new generated
+       objects to linker.  If there are offload sections, but no LTO sections,
+       then return the copies of input objects without link-time recompilation.
