Also on exposing PGO info, I have a patch that adds a pass I call HotnessDecorator. The pass emits a remark for each basi...

Hello all, In https://www.youtube.com/watch?v=qq0q1hfzidg, Adam Nemet (cc'ed) describes optimization remarks and some future plans for the project. I had a few follow-up questions: 1. As an example of future work to be done, the talk mentions expanding the set of optimization passes that emit remarks. However, the Clang User Manual mentions that "optimization remarks do not really make
