> consider Ctz8(010?0?0?) = 00000??0. ctz8 with actual Uninit input bits should be implemented by a helper function of two inputs (the operand, the bitmask of Valid bits) which uses table lookup. If the host lacks ctz8 (or similar) then the helper function should be called regardless of bit state. -- |
