You may look at http://gentoo-wiki.com/Safe_Cflags#Pentium-M_.2F_Centrino_.28Intel.29 |

If you use x86 (not ~x86) then you have a gcc < 3.4.3. The page above |
| 12 |
proposes to use: CFLAGS="-O2 -march=pentium3 -pipe". A friend of mine with |
| 13 |
a Pentium M uses CFLAGS="-O2 -march=pentium4 -pipe -fomit-frame-pointer", |
| 14 |
which is dangerous if you believe the wiki-page. |

If you plan to use gentoo on many x86 systems with different CPU's and you |
| 17 |
want to share binarys. I recommend to use: CFLAGS="-O2 -march=i686 |
| 18 |
-fomit-frame-pointer -pipe" (runs on any Intel/AMD/... starting from |
| 19 |
Pentium2-class CPU). |
