What, if any, CPUTYPE setting in /etc/make.conf makes sense for an opteron running in i386 mode? I'm not sure how much tuning GCC 3.3.3 actually provides when fiddling with things like this, so maybe it doesn't matter. I would use k8 or opteron, but neither are listed as options in /usr/share/examples/etc/make.conf. athlon-xp and athlon-4 seem the next best bet, with (I think) athlon-4 edging out athlon-xp due to support for SSE2 instruction sets. Should I even bother with this? - a.
