| 4 | CFLAGS="-O2 -march=native -pipe" |

| 7 | On my system, it gives me (I have a core 2 duo) |
| 8 | CFLAGS="-O2 -march=nocona -mtune=generic -pipe" |
| 9 | while with gcc-4.3, I get |
| 10 | CFLAGS="-O2 -march=core2 -mtune=core2 -pipe" |
| 11 | |
| 12 | So -march=native handles both, -march and -mtune |
