[llvm-dev] '-fsave-optimization-record' and VS2015 built compiler

Not 100% if this is an LLVM question or a CLang question, though I expect LLVM.

On Linux, if I pass '-fsave-optimization-record' to 'clang', then it produces a '*.opt.yaml' file.  However, the same thing run on Windows using 'clang' built with VS2015 silently ignores this option.

Is this a bug or is it intentional?  And if it is intentional, how can I configure and build on Windows to enable this feature?
