 described in the TOSA specification document  under Section 1.3 Operator
 Selection. Explanation of the thinking behind some operators is listed here:
 
-### IDENTITYN
-
-tosa.IDENTITYN is used to form a list of Operator results during
-lowering of operations such as tf.Split from a sequence of tosa.SLICE
-ops.  If there are alternate ways to express this lowering without the
-tosa.IDENTITYN op, the tosa.IDENTITYN op could be removed from TOSA.
-
-```
-Value lower_split_op(Value %value, size_t axis, size_t
-num_split) { Value %output[]
-
-    size_t slice_size = %value.shape[axis] / num_split
-
-    for (int i = 0; i < num_split; i++) {
-        vector <size_t> begin_vals, size_vals
-
-        for (int j = 0; j < %value.rank; j++) {
-            if (j == axis) {
-               begin_vals.push_back(slice_size * i)
-               size_vals.push_back(slice_size)
-            } else {
-               begin_vals.push_back(0)
-               size_vals.push_bac(%value.shape[j])
-            }
-
-            %output[i] = tosa.SLICE(%value) {start=begin_vals, size=size_vals} (tensor<%value.type>) -> tensor<size_vals, %value.dtype>
-        }
-
-    }
-
-    %output_list = tosa.IDENTITYN(%output) (tensor<%output:*.type>) -> tensor<%output_list:*.type>
-    return %output_list
-}

 ### COND\_IF and WHILE\_LOOP
 
 Several neural networks express conditional control flow at the tensor level.
