- * The module defines a map that contains pairs (irnode, type). If an irnode
- * is not in the map it is assumed to be initialized, i.e., the initialization
- * requires no compute time. As firm nodes can not be freed and reallocated
- * pointers for nodes are unique (until a call of dead_node_elimination).
