- * Bestimmt fuer jede Call-Operation die Menge der aufrufbaren Methode

+ * Determines for each Call node the set of possibly called methods.
+ * Stores the result in the field 'callees' of the Call node. If the
+ * address can not be analysed, e.g. because it is loaded from a
+ * variable, the array contains the unknown_entity. (See
+ * "set_Call_callee"). cgana returns the set of 'free' methods, i.e.,
+ * the methods that can be called from external or via function
+ * pointers. This datastructure must be freed with 'free()' by the
+ * caller of cgana.
+ *
+ * cgana sets the callee_info_state of each graph and the program to
+ * consistent.
