I have -march=amdfam10 (Phenom) and I once watched the compilation of |
15 |
ffmpeg and it said something like "CPU family amdfam10 unknown" and it |
16 |
changed some of the CFLAGS (I can't remember which exactly) so I guess |
17 |
something like this is already somewhere under the hood. |

But I agree that a USE-Flag to decide over this behaviour would be great. |
