[Interest] clang in Visual Studio Codegen supported?

[Hamish Moffatt]

Is Microsoft's clang add-on for Visual Studio 2015 (CodeGen) supported 
for compiling Qt applications? (With Qt 5.8?)

I tried (qmake -tp vc, change settings to CodeGen etc) but didn't get 
far; the very first source file failed to compile with:

I'm compiling for 32-bit.
