Do you mean 0002? 0001 just adds a 2-register loop for remaining elements once we've exhausted what can be processed with the 4-register loop. > - if short, do one element at a time and return 0002 does this. > - if long, do one block unconditionally, then round the start pointer > up so that "end - start" is an exact multiple of blocks, and loop over > them 0002 does the opposite of this. That is, after we've completed as many blocks as possible, we move the iterator variable back to "end - block_size" and do one final iteration to cover all the remaining elements. -- Nathan Bossart Amazon Web Services: https://aws.amazon.com
