+// Regression test for #39828. If you make use of a module that
+// consists only of generics, no code is generated, just a dummy
+// module. The reduced graph consists of a single node (for that
+// module) with no inputs. Since we only serialize edges, when we
+// reload, we would consider that node dirty since it is not recreated
+// (it is not the target of any edges).
