How can I associate my NVRTC program source with a file?

I'm using NVRTC to compile a kernel. The relevant API call is:

nvrtcResult nvrtcCreateProgram ( 
    nvrtcProgram* prog,
    const char* src,
    const char* name, 
    int  numHeaders, 
    const char** headers,
    const char** includeNames )

As you can see, the source is a raw string, and not associated with a file. That means that when you --generate-line-info, you get line numbers, but no related filename. And that means that if you then use, say, NSight Compute - you won't be able to see your kernel source code.

Obviously, neither NSight Compute itself, nor NVRTC itself, can figure out that the raw source is mirrored in some file. But there has to be some way to get around this:

• Perhaps I'm missing something in the NVRTC API which can make the source <-> file association?
• Perhaps we can manipulate the resulting compiled program (reasonably, not manually, or write-my-own-new-API) to make the association?
• Perhaps we can shove the source code into the compiled program somehow?

It seems NVRTC does provides a default filename, such that if you place your source in the file with that name - NSight Compute may be able to find it.

The name is the one you passed to nvrtcCreateProgram() as the name argument.

So, if your kernel function (i.e. your __global__ function) is in my_kernel.cuh, and you place this file in the working directory of the profile program (which you tell NSight Compute about), or in one of the include directories you built your program with, you'll be able to read your source. If the original file's own directory is also one of the include directories, then you're in luck and you don't even have to make a copy.
