In this talk, we will discuss how to enable hardware PGO by extending sampling-based PGO with enriched profiles. We will postmortem some real cases to demonstrate hardware PGO can expose more optimization opportunities than instrumentation-based PGO and thus provide better performance. Moreover, we will discuss how to enable hardware PGO on Windows based on the latest Intel VTune SEP.
