...ood reference point for "compilation-local singleton stuff". My task is to provide a way to handle callbacks per-compilation-context, and preferably have a single copy of those (possibly stateful) callbacks per compilation. In my implementation (linked at the end of RFC) I'm using PassInstrumentationImpl to have a single copy of object. What entity should *own* PassInstrumentationImpl object to make it unique per-compilation? Again, in my implementation with Analysis-managed PassInstrumentation I put Impl into PassBuilder which registers Analyses with a reference to its Impl. However that makes...

TL;DR ==== This RFC suggests an API to enable customizable instrumentation of pass execution. The intent is to have a common machinery to implement all the pass-execution-debugging features mentioned here. Prime target of the interface is the new pass manager. The overall approach and most of the implementation details should be equially applicable to the legacy one though. Background
