You don't need to follow this guide. Just emerge and you'll be fine. |
| 29 |
However, you might want to make adjustments to CFLAGS (especially when |
| 30 |
you have a newer CPU, there are new -march settings for your chip) and |
| 31 |
reemerge cpu-intensive programs and maybe important libraries like glibc |
| 32 |
to profit from the new features. |
