+// FIXME(#27438): right now the unit tests of librustc_middle don't refer to any actual
+//                functions generated in librustc_data_structures (all
+//                references are through generic functions), but statics are
+//                referenced from time to time. Due to this bug we won't
+//                actually correctly link in the statics unless we also
+//                reference a function, so be sure to reference a dummy
+//                function.
