I doubt that, especially for the 1-element (non-zero DC) IDCT case. The
other one handles 10 elements.

I wrote most of this 2 years ago, probably with the thinking that I
would optimize it later. I suppose now is later so it's time to get back
to work on it.

I think the x86 ASM routines should be written in Intel/NASM syntax so
they could be compiled under Microsoft compilers as well (and NASM under
Linux). Or perhaps an intermediate macro language that could be
converted to Intel or AT&T syntax. But that's just me.
