Ah, I see where you may have got confused. I meant regarding the automatic application of rules based on profiling.

  What are you looking for that is not currently part of the profile guided optimization capabilities of current compilers? It has been the case for years that you can compile a program with profiling/tracing hooks, run it through a representative workload, and feed the profiler output back to the compiler to get a faster executable. That's why no Firefox you compile yourself will outperform the one you download from Mozilla, if you only compile it a single time.

    In my experience, none change the source-code themselves.

      Feature or bug?
