* 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.
