If you're using the the GCC from stable ("x86") portage (GCC 3.3), then |
8 |
you should probably use something like: |
9 |
|
10 |
CFLAGS="-O2 -march=pentium3 -msse2 -pipe" |
11 |
|
12 |
GCC 3.4 (marked unstable, "~x86") makes it a little simple by adding |
13 |
a Pentium-M specific architecture type: |
14 |
|
15 |
CFLAGS="-O2 -march=pentium-m -pipe" |
16 |
|
17 |
Although, on a laptop you might want to use "-Os" (size optimization) |
18 |
in place of "-O2", as the disk is a lot slower than desktop machines |
19 |
and you will probably have longer startup times for programs. I'm not |
20 |
too sure on that last part, a I don't have a laptop, though. Anyone |
21 |
else want to take a stab at that? :) |

Hope that helps. |
