It's amd64, as well. Unfortunately, depending on your CFLAGS you might |
| 27 |
still have incompatible code on your current system. You can still try |
| 28 |
it but you will likely encounter random process crashes because of |
| 29 |
invalid opcodes. |
| 30 |
|
| 31 |
You can avoid a complete reinstall by changing your CFLAGS to something |
| 32 |
generic like '-march=i686' and remove anything else not supported by |
| 33 |
both processor families. |
| 34 |
Then make a `emerge --emptytree world` to recompile all packages. |
| 35 |
|
| 36 |
Don't forget to adjust your kernel as well. |

For your specific CFLAGS, look here: |
