By "best" I mean creating the fastest programs that exploit fully all of the architecture's features, without creating a "noticible" increase in size. To date I've been using CFLAGS="-O3 -march=athlon-xp -mfp-math=sse -funroll-loops -pipe -ffast-math" __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
