[PATCH] D94001: [CSSPGO] Call site prioritized BFS inlining for sample PGO

[David Li via Phabricator via llvm-commits]

davidxl added a comment.

A few high level questions:

1. Can the size bloat problem be handled in llvm-profgen time ? Basically using hotness information to prune/merge profiles properly?
2. What is the intuition behind BFS order?
3. How often does the size limit get triggered with the new inliner?
4. what is the largest improvement in spec06? Any internal benchmark data?
