Working group sync


  • PGO stands for Profiler Guided Optimization.

  • Code is instrumented and then run. The profilng data gathered at runtime is then used in subsequent compilations to guide optimizations.

  • PGO support is almost complete!

    • The remaining work is mostly just around the UI side of things: documenting compiler flags, moving flags from -Z to -C.
