Performing the [[Subtracting a Rook from a Blocking Piece|o^(o-2r) - trick ]] in a [[SIMD and SWAR Techniques|SWAR-wise]] fashion with bytes (ranks), saves some instructions compared to [[Kogge-Stone Algorithm|Kogge-Stone]].
[[include page="{{MappingHint"]]}}
Unfortunately it only works in positive horizontal direction, so the possible savings are marginal, despite even less generalization of handling one out of eight cases with a different code pattern.
