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

You said you don't want an increase in size. But that's
exactly what -O3 (via inlining) and -funroll-loops do.
If you want not to increase

That's true for stock GCC but FreeBSD (6.x) CFLAGS, COPTFLAGS, and
CXXFLAGS defaults to -O2
