Tobias Burnus 33c4e46624 Add 'default' to -foffload=; document that flag [PR67300] ... As -foffload={options,targets,targets=options} is very convoluted, it has been split into -foffload=targets (supporting the old syntax for backward compatibilty) and -foffload-options={options,target=options}. Only the new syntax is documented. Additionally, -foffload=default is supported, which can reset the devices after -foffload=disable / -foffload=targets to the default, if needed. gcc/ChangeLog: PR other/67300 * common.opt (-foffload=): Update description. (-foffload-options=): New. * doc/invoke.texi (C Language Options): Document -foffload and -foffload-options. * gcc.c (check_offload_target_name): New, split off from handle_foffload_option. (check_foffload_target_names): New. (handle_foffload_option): Handle -foffload=default. (driver_handle_option): Update for -foffload-options. * lto-opts.c (lto_write_options): Use -foffload-options instead of -foffload. * lto-wrapper.c (merge_and_complain, append_offload_options): Likewise. * opts.c (common_handle_option): Likewise. libgomp/ChangeLog: PR other/67300 * testsuite/libgomp.c-c++-common/reduction-16.c: Replace -foffload=nvptx-none= by -foffload-options=nvptx-none= to avoid disabling other offload targets. * testsuite/libgomp.c-c++-common/reduction-5.c: Likewise. * testsuite/libgomp.c-c++-common/reduction-6.c: Likewise. * testsuite/libgomp.c/target-44.c: Likewise.		2021-06-29 16:00:04 +02:00
