Sure, I intentionally omitted anything that was already in lavc (tables, 
fft, imdct, bitstream reader, ...) because we'll have those whether or not 
we include this codec. That's just quantifying a benefit of having it part 
of lavc instead of external.
OK, so that doesn't hold if you want to measure the impact on icache, but 
then you can't just look at the total object size because it includes 
multiple versions of the dsp functions.
