I really don't know. I mean, I particularly always stick to Gentoo Safe Cflags, but I know people that use a 32-bit profile and use -march=nocona. Let's see what other ppl have to say. On 1/25/08, John covici [EMAIL PROTECTED] wrote: on Friday 01/25/2008 Andrey Falko([EMAIL PROTECTED]) wrote

Thats correct and be happy, because if so, you have to start from a amd64 stage and not from x86 one. John covici schrieb: on Friday 01/25/2008 Andrey Falko([EMAIL PROTECTED]) wrote On Jan 25, 2008 10:00 AM, John covici [EMAIL PROTECTED] wrote: Hi folks. I right now have my CCFLAGS

Well, I'd change my CFLAGS, for sure, so that I'd get all the benefits of having that better processor. What's your profile: x86 or x86_64 (amd64)? For your processor, according to http://gentoo-wiki.com/Safe_Cflags (that I always like to check): Intel Core 2 Duo/Quad / Xeon 51xx/53xx

Hi folks. I right now have my CCFLAGS set to CFLAGS=-O2 -mtune=athlon-xp -pipe -- now I am getting one of those new Intel e8400 CPU's and so I have two questions. What should I change my CCFLAGS to -- and do I have to recompile the whole system after this is done or what? Thanks in advance for
