This doesn't work with the cuda-bindings from the 12.9.x backport branch, e.g.:

https://github.com/NVIDIA/cuda-python/actions/runs/24091305075/job/70279241852?pr=1837

tests/test_program.py:76: in _check_nvvm_arch
    from cuda.bindings.utils import check_nvvm_compiler_options
E   ImportError: cannot import name 'check_nvvm_compiler_options' from 'cuda.bindings.utils' (/opt/hostedtoolcache/Python/3.10.20/x64/lib/python3.10/site-packages/cuda/bindings/utils/__init__.py)

@leofang wrote under #1457:

We should expose it to cuda.bindings.utils, similar to the PTX version helpers.

That makes using it from cuda_core/tests/ a little tricky: it'll only be in future cuda-bindings releases.

@leofang how would you handle this situation?

@abhilash1910 — Offline we decided (roughly): let's move the (or some) tests to cuda_bindings/, and if we want to keep certain tests in cuda_core/, skip them if cuda.bindings.utils.check_nvvm_compiler_options is not available. Could you please try how that shakes out? Please ping me on chat if you have questions.
