The approach for handling reductions in the outer most dimension follows that for inner most dimensions, outlined below First, transpose to move reduction dims, if needed Convert reduction from n-d to 2-d canonical form Then, for outer reductions, we emit the appropriate op (add/mul/min/max/or/and/xor) and combine the results.
