Hi list, |

|
| 3 |
my laptop's cpu is AMD Turion64x2, I've installed both 32bits Debian |
| 4 |
testing and Gentoo on it, |
| 5 |
from Debian there is no SSE3 in /proc/cpuinfo, |
| 6 |
and I used CFLAGS="-O2 -march=athlon-xp -fomit-frame-pointer -pipe" on |
| 7 |
gentoo, and I can not see SSE3 in cpuinfo also, |
| 8 |
|
| 9 |
I emerged x86info, and SSE3 is in its output: |
| 10 |
|
| 11 |
#x86info |
| 12 |
x86info v1.21. Dave Jones 2001-2007 |

my question is: I can not see SSE3 in cpuinfo because I did not use |
| 38 |
"-msse3" in CFLAGS ? |
