the standard build is optimized for size ???
On Apple:
-Os Optimize for size, but not at the expense of speed. -Os
enables
all -O2 optimizations that do not typically increase code
size.
However, instructions are chosen for best performance,
regardless
of size. To optimize solely for size on Darwin, use -Oz
(APPLE
ONLY).
(fdn~ NOT vectorized; d_soundfile.c, d_ctl.c, m_sched.c
vectorized)
have the _whole_ files been vectorized or only certain loops? which
loops have been vectorized, which haven't?
That I don't know, you'll have to compile with higher vectorizing log
level than I did. But not all the loops were vectorized, only some.
s_audio.c had a lot of loops vectorized, so you can choose your
soundcard really fast with this build ;)

more direct solution... It may sound small in theory, but it in
practice, it can change entire economies. - Amy Smith
