from my experience the contrary is true. last time i checked the
assembly code produced by -O3 i found nothing to object to. that
was g++ 2.95 compiling drawing routines on rgb buffers (just ints,
no floats, but comparable to audio dsp in a way).
i admit i designed the code around what i expected the optimizer
to do to it, so yes, maybe you need a little experience to get it
right.
