tra added inline comments.


================
Comment at: clang/lib/Driver/ToolChains/Cuda.cpp:632
+  if (mustEmitDebugInfo(DriverArgs) == EmitSameDebugInfoAsHost)
+    CC1Args.push_back("-D__CUDACC_DEBUG__");
+
----------------
Built-in preprocessor macros are defined in  clang/lib/Frontend/InitPreprocessor.cpp, so the change should ideally go there.

Also, it's not clear what exactly does the macro mean. I am not convinced that clang must set this macro. Clang is not 1:1 compatible with NVCC anyways, and I'd rather not add quirks unless they are absolutely necessary. In this case, it can be easily added by the user.
