Since Visual Studio 2017, Microsoft has an optional C++ Desktop Development option for compiling C/C++ code with LLVM's Clang compiler.
It's called: Clang with Microsoft CodeGen.
While the code is parsed with LLVM's Clang parser, the code is generated with a MSVC compatible code generator (hence the "with Microsoft CodeGen" name suffix)
Currently, Python 3.10 is uncompilable with Clang, but I would appreciate it if it can be supported.
I have attached a build log from MSBuild, below is the commandline I used to run the build.
Start-Process -FilePath $(Join-Path $PCBUILD -ChildPath 'build.bat' -Resolve) -WorkingDirectory $PCBuild -NoNewWindow -RedirectStandardOut $BUILD_LOG -RedirectStandardError $BUILDERROR_LOG -ArgumentList '-m', '-v', '-c', 'Debug', '-p', 'x64', '-t', 'Build', '"/p:PlatformToolset=ClangCL"'
