Prepare to debug CUDA GPU code

You might need to add additional compiler command line options to enable GPU debugging.

For NVIDIA's nvcc compiler, kernels must be compiled with the -g -G flags. This enables generation of information for debuggers in the kernels, and also disables some optimizations that would hinder debugging. To use memory debugging with CUDA, –cudart shared must also be passed to nvcc.

For other compilers, see NVIDIA GPU language support, and your vendor's own documentation.
