+- 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`.
