Unfortunately, it's applicable only to key setup, and unrolling happens in actual encryption. But the point still stands: irrespective of other optimizations, unrolled and non-unrolled forms will still have different sizes and speeds, and in some cases (like this one) you can't pick one form which fits all. > Please submit this new version :-) Just did it.
