[PATCH] D15462: [CMake] Add support for generating profdata for clang from training files

[Sean Silva via cfe-commits]

Can you elaborate on why this patch is restricted to unix?

Also, this probably requires some documentation in
http://llvm.org/docs/CMake.html
(we don't really have an analogous page just for clang currently, so the llvm one is probably the best place right now)

----------------
Can you write a tiny pure-Python helper script for clear-profraw and another for generate-profdata? That will be more portable.

If this is the only thing blocking windows support, I think that shooting for windows support on the initial patch is worth a shot.
