I've just installed the LLVM 7.0.0 for Windows (64-bit) released few hours ago.
With the new version, all the platform toolsets provided by the previous release (6.0.1) for Visual Studio 2015 (named "LLVM-vs2014", "LLVM-vs2014_xp" and "LLVM-vs2010") are not available anymore.
I've seen a new extension named LLVM Compiler Toolchain in the Visual Studio Marketplace, but it is not available for Visual Studio 2015.
Do you know the reasons of this lack?
