I wouldn't bother setting CPUTYPE at all. It's more trouble than it's worth. And you're right: for most ports and for the whole system, it doesn't really matter. If you have a very specific port that needs particular tuning, it has either already been tuned individually by the port maintainer, or you could apply more optimizations yourself (which would likely require a specially compiled tool chain, when -O<something> with the base gcc/binutils isn't enough). Unless you have a very specific need, better leave CPUTYPE alone. > Your use of athlon64 seems reasonable to me. It is what I've been using.
