-#ifdef INTERPROCEDURAL_VIEW
-/** Constructs backedges for all irgs in interprocedural view.

- * @see As construct_backedges(), but for interprocedural view.

- * @remark
- * All loops in the graph will be marked as such, not only
- * realizeable loops and recursions in the program. E.g., if the
- * same funcion is called twice, there is a loop between the first
- * function return and the second call.
