IIRC Firefox uses clang-cl on windows builds

Chromium uses Clang for Windows since 2018: Clang is now used to build Chrome for Windows - The LLVM Project Blog

I believe LibreOffice is another example, but I don’t have a link for that.

Rizin:

We use clang-cl to prepare artifacts along with VS builds using both AppVeyor and GitHub Actions CI jobs.

Not sure I understand your question. In both cases, we use Meson buildsystem which can either use MSVC (VS) toolchain or the clang-cl one, see details in our CI files I linked earlier.

See official document for LLVM (clang-cl) toolset (for VS 2019, 2022) at https://learn.microsoft.com/en-us/cpp/build/clang-support-msbuild?view=msvc-170, it may only works with bundled old LLVM available in Visual Studio installer.

or you can use this one maintained by me: GitHub - zufuliu/llvm-utils: LLVM/Clang toolsets for Visual Studio 2022, 2019, 2017, 2015, 2013, 2012 and 2010. (for VS 2010 and above and any LLVM), see online builds for VS 2019 and 2022 at Actions · zufuliu/notepad2 · GitHub, and VS 2017 at AppVeyor.
