I've recently gotten a VIA Nano board, and was wondering how long until GCC has specific support for it. Right now (4.3.2) -march=native -v says it's using -march=core2, but the code produced sometimes doesn't run. I'm guessing there are some things core2 supports that nano doesn't. Any guesses as to working optimization flags in the current GCC? (I'm running as a x86-64 host so I'm assuming mmx, sse, see2 are on by default.) Would -msahf work? -Morgan Wahl
