 ''Syntactic'' transformations (from ancc module):
- * Non-Rectangular Register tiling 
+ * Register tiling 
  * Scalar replacement (to enhance register reuse)
+ * Loop permutation/interchange
  
 It is to be noted that the register tiling approach used by PLuTo is limited to only rectangular loops. To further improve the resulting performance, we implemented our new register tiling approach as one of the ancc's transformation modules. Our register tiling approach is so general that it can handle both rectangular and non-rectangular loops.
