+    Vectorize to a target independent n-D vector abstraction.
+    This operation is an exposition to the transform dialect of the affine-super-vectorize pass.
+    To make its usage easier, it ignores inputs which are children of an affine.for op (itself excluded),
+    this way the matcher can be simpler.
+
+    Example:
+    ```
+    %0 = transform.structured.match ops{["affine.for"]} in %arg1 : (!transform.any_op) -> !transform.any_op
+    transform.affine.super_vectorize %0 [8, 16] fastest_varying_pattern=[1,0] vectorize_reductions=true : !transform.any_op
+    ```

+  let results = (outs);
