Is clang-cl officially supported as a host compiler on Windows?

The documentation is being vague about it.

Here - CUDA Installation Guide for Microsoft Windows it says:

Windows Compiler Support
…
MSVC Version 193x
MSVC Version 192x
MSVC Version 191x

but the aforementioned versions of Visual Studio (at least 2019 and 2022) allow to use clang-cl.exe compiler as well.

So is it possible to use clang-cl instead of Microsoft’s cl compiler as a host compiler. I know about nvcc’s --ccbin option, but is it officially supported?

I have tried LLVM on Windows. It output: ‘nvcc fatal : Host compiler targets unsupported OS’

You must use cl.exe, the compiler that ships with Visual Studio with the Visual C++ support, as a host compiler for nvcc on “native” windows. (WSL2 is a separate case.)

The excerpted document portion for compiler support:

does not indicate Visual Studio, it indicates MSVC; that is Microsoft Visual C++, which is referring to a specific compiler toolchain from microsoft, not clang.

Here for example, we can see that microsoft differentiates MSVC from clang:

" including MSVC, Clang, "
