Ah thank you. I've since ran some experiments and found that after https://reviews.llvm.org/D116051 the number of profiled functions is about what we expect without this patch. However, I'm working on another patch that only profiles function entry coverage and this code change is needed in that case. I'll do more investigation and follow up more.
