I run this on dozens of amd64 laptops and 3workstations and servers
from make.conf:
USE="mmx mmxext sse sse2 sse3 3dnow 3dnowext \
no problems, great performance!
Here is something nice from that palladies dude I keep in my
.bashrc:
# USE flag settings hack by Ciaran McCreesh:
explainuseflag(){ sed -ne "s,^\([^ ]*:\)\?$1 - ,,p" $(portageq
portdir)/profiles/use.{,local.}desc; }
alias ef="explainuseflag"
ef sse3
Enable optimisations using the sse3 assmbly code
Enable SSE3 support
ef ssse3
faster floating point optimization for SSSE3 capable chips (Intel Core 2 and
later chips)
My wife just loves Palladis exercise class....
