Mark Dickinson <dicki...@gmail.com> added the comment: I think I've found the happy medium:
bit_length7_opt2.patch achieves nearly the same performance gains as bit_length7_opt.patch (around 7% for uniformly-distributed inputs, 3.5% for uniformly-distributed outputs), but is much more straightforward and readable. It's pretty much what Raymond suggested in the first place, plus a table lookup.
