[CUDA 12] clang error: no template named 'texture'

[lahwaacz]

For a trivial foo.cu:

int main() {}

Running clang++ foo.cu results in:

clang-15: warning: CUDA version is newer than the latest supported version 11.5 [-Wunknown-cuda-version]

I believe that's already been fixed in recent clang: 8173405

@Artem-B Thanks for the info. Any chance of backporting it to clang 15, or do I have to wait for version 16 to be released? What is the general policy?

[Artem-B]

It's a low-risk fix which should be OK to cherry-pick, though I don't know the current state of the release process.

/cherry-pick 8173405

Now, with the 16.0.1 milestone. @tstellar - FYI.
