- * Creates an ir_graph pass for running void function(ir_graph *irg).
- * Uses the default verifier and dumper.
- * The pass returns always 0.
- *
- * @param name the name of this pass
- * @param verify should this pass be verified?
- * @param dump should this pass result be dumped?
- * @param params The parameters for the if conversion.
+ * This is a helper function used by some routines copying irg graphs
+ * This assumes that we have "old" nodes which have been copied to "new"
+ * nodes; The inputs of the new nodes still point to old nodes.
