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?

Sounds like a bug (I've never tested on Windows). I suggest filing a bug report. Also, in general, you'll have better luck with frontend questions on cfe-dev.
