Hmm, you're right:
ori.w #xxxx,yyyy(an) is 20 cycles.
However the reason why I'm not using register operands is just what evil suggests: the overhead of loading the registers. And I need a couple of data registers outside of the 16-pixel loop as well. So the question boils down to, is it worth the overhead outside of the generated code? The answer is not so obvious if you target lines which are like ~50 pixels in length instead of just optimizing for the longest possible diagonal line.

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
