On Windows with VisualStudio 2012 How to compile Compiler-RT and LLDB

I offer a Windows-based Clang release using VisualStudio, URL: https://sourceforge.net/projects/clangonwin/, but Compiler-RT can not be a good compilation, LLDB get going, there’s no such Libcxx support, I hope you give me help. Thank you.
