Hi, Pavel, I have the same problem with estelle's. and if I Instrument all methods, it will bring side effect to other methods. 2.

This is quite a simple to do but compiling one method from > another may be unsafe in case on complex type dependencies. When the pipeline compile foo(), callee's HIR is unavailable. If Use CompilationInterface.compileMethod() routine to run a full compilation of a callee from a compilation session of foo(). How to get HIR of callee? Whether the instrumented HIR will be overrided when the pipeline really compile callees? 3. Create a list of callees during the first run and then instrument > the callees during the next run.
