GCC - Optimal Optimization

[Sean M.]

With GCC 3.4.4, what are the best CFLAGS to use for an AMD Duron ~1000
MHz? 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"
