probinson added inline comments.


================
Comment at: clang/test/Preprocessor/lang-std.cpp:4
 // RUN: %clang_cc1 -dM -E %s | grep __cplusplus >%T-cpp-std.txt
+// RUN: cat %T-cpp-std.txt | FileCheck --check-prefix=CXX17 %s
+
----------------
Use `--input-file` and there's one fewer process to create.
