+# DP: Allow setting offload targets by OFFLOAD_TARGET_DEFAULT
+
+https://src.fedoraproject.org/rpms/gcc/raw/rawhide/f/gcc11-foffload-default.patch
+
+2019-01-17  Jakub Jelinek  <jakub@redhat.com>
+
+	* gcc.c (offload_targets_default): New variable.
+	(process_command): Set it if -foffload is defaulted.
+	(driver::maybe_putenv_OFFLOAD_TARGETS): Add OFFLOAD_TARGET_DEFAULT=1
+	into environment if -foffload has been defaulted.
+	* lto-wrapper.c (OFFLOAD_TARGET_DEFAULT_ENV): Define.
+	(compile_offload_image): If OFFLOAD_TARGET_DEFAULT
+	is in the environment, don't fail if corresponding mkoffload
+	can't be found.
+	(compile_images_for_offload_targets): Likewise.  Free and clear
+	offload_names if no valid offload is found.
+libgomp/
+	* target.c (gomp_load_plugin_for_device): If a plugin can't be
+	dlopened, assume it has no devices silently.
