As both CPUs that were tested had SSE4.1 capability, these functions were compared with. So yes, current GCC outperforms those SSE4.1 intrinsics functions on 16-bit inputs and comes close on 24-bit inputs. _______________________________________________ flac-dev mailing list [email protected] http://lists.xiph.org/mailman/listinfo/flac-dev
