"modern static vs dynamic predictors" That again. People jump right to static versus dynamic. Best to mix static and dynamic analysis to get best of both worlds. It was already done in both whole-program optimization and security to get some great benefits. My classic default is to feed the common case as test runs into an instrumented version of the system to get execution traces and measurements. That is combined with static analysis to provide better transformations or scheduling. Also, this is a high-level description of a solution that applies to many problems rather than just compiler components.
