  I too, would very much like to see this happen. If for nothing else
but to make it easier on me to tinker with OpenSPARC T2 optimizations. 

It seems to me that the architecture proposed by Luca has a very nice 
benefit of facilitating ports without making the person doing it go over
100+ different files to hunt down these one-liners. It also helps a lot
with compiling ffmpeg with different compilers, etc.

  So, the question is -- would there be a happy medium to which Michael
would agree ?

Thanks,
Roman.
