-   accessed in the loop by STMT, along with the def-use update chain to

-   aliasing information for the pointer.  This vector pointer is used by the

+   Create a new pointer-to-TYPE variable (ap), that points to the first

+   chain to appropriately advance the pointer through the loop iterations.
+   Also set aliasing information for the pointer.  This pointer is used by
+   the callers to this function to create a memory reference expression for
+   vector load/store access.
 
    Input:
    1. STMT: a stmt that references memory. Expected to be of the form
          GIMPLE_ASSIGN <name, data-ref> or
 	 GIMPLE_ASSIGN <data-ref, name>.
-   2. AT_LOOP: the loop where the vector memref is to be created.
-   3. OFFSET (optional): an offset to be added to the initial address accessed
+   2. AGGR_TYPE: the type of the reference, which should be either a vector
+        or an array.

+   4. OFFSET (optional): an offset to be added to the initial address accessed
         by the data-ref in STMT.

+   6. ONLY_INIT: indicate if ap is to be updated in the loop, or remain

-   6. TYPE: if not NULL indicates the required type of the data-ref.
 
    Output:
    1. Declare a new ptr to vector_type, and have it point to the base of the
       data reference (initial addressed accessed by the data reference).
       For example, for vector of type V8HI, the following code is generated:
 
-      v8hi *vp;
-      vp = (v8hi *)initial_address;

+      ap = (v8hi *)initial_address;
