From fe5bfa6704179f8db7d1ae0b485439e9896df8eb Mon Sep 17 00:00:00 2001 From: Tobias Burnus Date: Wed, 28 Apr 2021 18:46:47 +0200 Subject: offload-defaulted: Config option to silently ignore uninstalled offload compilers If configured with --enable-offload-defaulted, configured but not installed offload compilers and libgomp plugins are silently ignored. Useful for distribution compilers where those are in separate optional packages. 2021-04-28 Jakub Jelinek Tobias Burnus ChangeLog: * configure.ac (--enable-offload-defaulted): New. * configure: Regenerate. gcc/ChangeLog: * configure.ac (OFFLOAD_DEFAULTED): AC_DEFINE if offload-defaulted. * gcc.c (process_command): New variable. (driver::maybe_putenv_OFFLOAD_TARGETS): If OFFLOAD_DEFAULTED, set it if -foffload is defaulted. * lto-wrapper.c (OFFLOAD_TARGET_DEFAULT_ENV): Define. (compile_offload_image): If OFFLOAD_DEFAULTED and 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. * config.in: Regenerate. * configure: Regenerate. libgomp/ChangeLog: * configure.ac (OFFLOAD_DEFAULTED): AC_DEFINE if offload-defaulted. * target.c (gomp_load_plugin_for_device): If set and if a plugin can't be dlopened, silently assume it has no devices. * Makefile.in: Regenerate. * config.h.in: Regenerate. * configure: Regenerate. --- libgomp/config.h.in | 3 +++ 1 file changed, 3 insertions(+) (limited to 'libgomp/config.h.in') diff --git a/libgomp/config.h.in b/libgomp/config.h.in index 03123dc..e702625 100644 --- a/libgomp/config.h.in +++ b/libgomp/config.h.in @@ -143,6 +143,9 @@ */ #undef LT_OBJDIR +/* Define to 1 to if -foffload is defaulted */ +#undef OFFLOAD_DEFAULTED + /* Define to offload plugins, separated by commas. */ #undef OFFLOAD_PLUGINS -- cgit v1.1
