[PATCH] D81981: [PGO] Supplement PGO profile with Sample profile

[David Li via Phabricator via llvm-commits]

davidxl added a comment.

Why is the profile size increase? I expect the number of instrumented blocks remain mostly unchanged.

The reason for the question is that if the overhead is low, I think we should make the default to be true.
