You should be specifying '-march=athlon64'. |
30 |
|
31 |
'-athlon64' is not a valid CFLAG, also -sse/2 and -3dnow are all implied |
32 |
by -march=athlon64 and I'm quite sure that -mfpmath=sse is also the default |
33 |
on amd64. It may be useful to specify '-msse3' in the CFLAGS though if your |
34 |
cpu supports SSE3 as no -march setting implies it yet. Although it's unlikely |
35 |
that gcc utilises sse3 properly. |
36 |
|
37 |
I recommend the following CFLAGS: |
38 |
|
39 |
CFLAGS="-O2 -march=athlon64 -pipe" |
40 |
|
41 |
Adding -msse3 if appropriate for your cpu. |
