cl_nv_compiler_options Extension Where is this documented?

I would like to bring up this subject again… it seems there are additional -cl-nv-XXXXXX options, beyond what’s described in the CUDA 3.0 documentation. For example: The clcc project, discussed in this thread, uses -cl-nv-arch and -cl-nv-cstd.

Which other options are there, these days? Where is the document for CUDA 11.x, corresponding to that cl_nv extensions page for CUDA 3.0?
