--- Comment #12 from cand at gmx.com ---
Commented on the horizontal mapreduce.

> That has the issue that's it's a massive PITA to code, plus it's slow. Plus 
> there's the "access to non-4-offset regs stalls". Even if there's no ready 
> operation, it should be made easier and faster than a manual mapreduce loop.
