[compile-time] how to use http://llvm-compile-time-tracker.com/

hi,
I try to add a commit id of branch master in the following link, but it report No data for commit, so I want to known how to use it ?

http://llvm-compile-time-tracker.com/compare.php?from=baa5b54d43419b5d4a1ec36f3788c36d52187e11&to=8082a00286380d0dafa05bfe5ddfe6075b9769f9&stat=instructions

The LLVM build was broken at that time. The closest available range is this: LLVM Compile-Time Tracker

I’ve changed the error message for this case to mention the build failure and link to the build log, so this is more obvious in the future…

Thanks for your improvement
