Some current ideas

• Test popbit/square_of with intrinsincs, something like : bitboard_t popbit64(bitboard_t *bb) { bitboard_t first = _blsi_u64(*bb); *bb ^= lsb; return first; } square_t square_of(bitboard_t bb) { return _tzcnt_u64(bb); } loop: while (bb) { bitboard_t first = popbit(bb); square_t sq = square_of(first); } Or maybe faster: for (; bb; bb &= bb - 1) { sq = _tzcnt_u64(bb); }
