Subject: [gentoo-amd64] x86 processor options for opteron 165
Date: Sat, 11 Nov 2006 14:08:31 +0100	[thread overview]
Message-ID: <4555CB4F.20008@pro.onet.pl> (raw)

Hi,


As I am now trying to check the x86 dist against amd64, I have just a 
serious question about

CFLAGS="-march= ????? -O2 -pipe"

WHAT should I put into ????? to have full optimizations under x86 
distro? athlon-xp seems to NOT have a few features..and should I add 
msse msse2 msse3 and maybe some other features to USE flags ?

my cpu is Opteron 165 (dual core)


-----
PS - I just have to check some things, and will NOT dive into x86 only 
:) as I know I will have 30% better performance with x86_64 - BUT I need 
your advice ;))


regards,
