 |
|
I have bought an AMD64 3500+ processor.
I understood from the AMD64 handbook that I should put "march=k8" in my make.conf (CFLAGS="march=k8 -pipe -O2"
But during compilations (textinfo, pciutils) I get the following error:
x86_64-pc-linux-gnu-gcc: march=k8: no such file or directory
Help plse.

-march=k8

If your Athlon-64 has one of the following cores:
- Venice
- San Diego
- Manchester (only in dual-core X2 CPUs)
- Toledo (only in dual-core X2 CPUs)
or newer than the above
make sure that you also add the following:
to take advantage of the fully supported SSE3 instructions.
So your CFLAGS line in make.conf should be:
| Code: | CFLAGS="-march=k8 -O2 -pipe -msse3"
