+//===- CloneFunction.cpp - Clone a function into another function ---------===//
+//
+// This file implements the CloneFunctionInto interface, which is used as the
+// low-level function cloner.  This is used by the CloneFunction and function
+// inliner to do the dirty work of copying the body of a function around.
