   - const function name (done)
   - remove the redundant edge from blocks that break a loop
   - ``<<`` operation in pre-calculation
+  - support ``addui``, ``sll``, etc.
 
 - Not Implemented:
 
   - complex type name (to be in agreement with complex decl) (done)
   - initializer checking (done)
   - typedef support (via adding mid-rule actions to bision to inform flex) (done)
