More a question than issue. I was impressed with your lecture at CoreCPP and right away tried to apply this project to quite large one which I familiar with. It is clickhouse - large and CPPish. I've built it with -fsave-optimization-record, release with debug info, and it was linked using ThinLTO, clang and lldb 11. Took quite a while. Then I ran the optview2 and... got 4 (four!) lines report about failing inlining. What I did wrong? I was expecting to get hundreds or even thousands of failed optimizations!
