Sorry about all the noise today. I guess it goes with building a new |
| 2 |
architecture for the first time. |

|
| 4 |
I am going to run 32-bit Gentoo on an AMD64 dual processor laptop. |
| 5 |
Would I be making a reasonably good setting using this in make.conf? |
| 6 |
|
| 7 |
CFLAGS="-O2 -march=k8 -pipe" |
| 8 |
CXXFLAGS="-O2 -march=k8 -pipe" |

I referenced this page to try to decide: |

|

http://gcc.gnu.org/onlinedocs/gcc/i386-and-x86_002d64-Options.html |
| 13 |
|
| 14 |
My single processor AND64 Gentoo machine uses k8. Not sure if I should |
| 15 |
change anything for a dual processor. |
| 16 |
|
| 17 |
If someone is running a machine like that and can provide a complete |
| 18 |
make.conf file that would be great. |
