That's defined by the compiler target architecture and/or CPU. Adding a configure flag wouldn't work since the compiler wouldn't know that it can use emit Zbb instructions for the corresponding built-ins. And before you ask, to my knowledge, GCC exposes no ad-hoc `-m` flags. This has to be included in -march or -mcpu instead, e.g.: CFLAGS="-march=rv64gc_zba_zbb" -- 雷米‧德尼-库尔蒙 http://www.remlab.net/ _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
