Description
I am using standard gdb with code that has CUDA library calls. I don't need to debug the CUDA specific code, but would like the functionality of rr for the host code. Is there a way to achieve this?
Currently when using rr record on a binary that calls cuInit() I receive a CUDA_ERROR_NO_DEVICE assertion.

Research direction
Start by reproducing the failure with rr record on a binary that calls cuInit(), and inspect how rr handles the resulting CUDA_ERROR_NO_DEVICE assertion. Done means establishing whether host-code recording can work while CUDA-specific code is ignored, then documenting or implementing the required support.
