...some of the things I'll be looking into. I'm not yet done wordsmithing the overall design document. I'll try to finish it by early next week at the latest. In the meantime, these are the specific bugzilla issues I've opened: 22716 <http://llvm.org/bugs/show_bug.cgi?id=22716>librarieGlobal A dnovillo at google.comNEW---Need a mechanism to represent global profile counts in CFG and MachineCFG <http://llvm.org/bugs/show_bug.cgi?id=22716> 16:47:0122718 <http://llvm.org/bugs/show_bug.cgi?id=22718>librarieGlobal A dnovillo at google.comNEW---Information loss and performance is...

We (Google) have started to look more closely at the profiling infrastructure in LLVM. Internally, we have a large dependency on PGO to get peak performance in generated code. Some of the dependencies we have on profiling are still not present in LLVM (e.g., the inliner) but we will still need to incorporate changes to support our work on these optimizations. Some of the changes may be addressed
