Hello David! I have recently started acquaintance with PGO in LLVM/clang and found your e-mail thread: http://lists.llvm.org/pipermail/llvm-dev/2016-May/099395.html . Here you posted a nice list of optimizations that use profiling and of those which could be using but don't. However that thread is about 2 years old. Could you please kindly let me know if there were

About Clang llvm PGO
Thanks for testing out LLVM PGO and evaluated the performance. We are currently still more focused on infrastructure improvement which is the foundation for performance improvement. We are making great progress in this direction, but there are still some key missing pieces such as profile data in inliner etc. We are working on that. Once those are done, more focus will be on making more passes
