" Mobile Sempron (AMD)
vendor_id : AuthenticAMD
cpu family : 15
model : 8
model name : Mobile AMD Sempron Processor 2800+
CHOST="i686-pc-linux-gnu"
CFLAGS="-march=athlon-xp -msse3 -O2 -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"
If you have a Sempron without SSE3 (earlier chips), omit "-msse3".
SSE3 is called pni (prescott new instuction) by cpuinfo (cat /proc/cpuinfo).
Check it out, there are many different sempron mobile CPUs on sale, those that
work at 1.8GHz are K8 (i.e. AMD SM 3000+), some others, older, aren't yet k8
but they're still k7 so you must specify athlon-xp instead of athlon64,
anyway AMD announced in 2006 there will be 64bit Sempron Mobile CPUs so be
carefull and pay attention, run a cat /proc/cpuinfo and then ask on AMD
forums if you don't know what to do."
