Is there a need for all that? It's used for gcc because the gcc developers decided to randomly use -march and -mcpu with no sense or system. If -march=native always does the right thing for clang, just testing if it is accepted should be enough? _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
