================
Comment at: test/SemaCUDA/extern-shared.cu:4
+// These declarations are fine in separate compilation mode!
+// RUN: %clang_cc1 -fsyntax-only -fcuda-rdc -verify=rdc %s
+// RUN: %clang_cc1 -fsyntax-only -fcuda-is-device -fcuda-rdc -verify=rdc %s
----------------
Nit. `-verify=rdc` is somewhat confusing as there's no rdc prefixes in the checks below. Perhaps something along the lines of `-verify=there-should-be-no-errors`  would be more descriptive.
