Comment at: clang/lib/CodeGen/CodeGenModule.cpp:6845-6846
+    llvm::MD5::MD5Result Result;
+    for (const auto &Arg : PreprocessorOpts.Macros)
+      Hash.update(Arg.first);
+    Hash.final(Result);
----------------
Are these options always the same for device and host compilation?

If not, this may not work since host and device compilation will have different names for the same variable.
