Detailed Description

This file defines the Pass Instrumentation classes that provide instrumentation points into the pass execution by PassManager.

There are two main classes:

PassInstrumentation object is being used as a result of PassInstrumentationAnalysis (so it is intended to be easily copyable).

Intended scheme of use for Pass Instrumentation is as follows:

TODO: currently there is no way for a pass to opt-out of execution control (e.g. become unskippable). PassManager is the only entity that determines how pass instrumentation affects pass execution.
