I think the response was generally positive but I haven't had the time to push things into tree. @clayborg, have you tried out the tool here: https://github.com/vedantk/llvm-project ? The RFC has some usage instructions.

If you just want the ratio of inlined to not-inlined bytes, this patch is a simpler way to do it. But if you need something more fine-grained (i.e. *which* functions were inlined more compared to a baseline, by how much, etc.), it might be worth checking out. Happy to have someone else run with the code.
