Looks sane, I maybe had checked before clbss_l, jumped over clear loop if r0 and r1 equal (to emphasize the fact that this is a check for entry correctness) and wouldn't change the loop at all. To be more precise we could also check if end is after start.
Well, I just realized you do check for less ;)
