Hi All I am trying to trace the execution path of J3 jvm with input of java byte code . Once java byte codes compiled in to llvm IR it will be passed to VMKit for store them . I couldn't find out which function is getting this Jitted output from *Functioncache* and executing them ? because , VMKit doesn't have an implementation of llvm Executionengine's *runFunction*

Hi Gael I am sorry that I couldn't explain what I was trying to say, anyway I've got the answer :) . In the *parseFunction* method returns *llvmfunction* pointer of compiled method and then it will be stored in to cache. Could you please more elaborate on how those machine instructions ( native functions) executing by llvm. I was trying trace and I couldn't able to find out which component is taking those nativ...

Hi, I am wondering how I can get the JIT'd llvm IR during VMKit execution. I am stuck in precompiling phase (when loading library classes), and I am facing various problems. If I can log the JIT'd llvm IR (from Java bytecode), that would be convenient. I turned on --enable-debug, but it doesn't seem very helpful at this stage. Any other suggestion is welcome. Thanks very much.

Hi VMKit JIT has a function cache to store compiled IR code , so, as soon as method is compiled , it will be stored in to function cache. My question is , who will use this compiled information from function cache. Since we are jitting , the llvm translate source code in to native code and executing them . So, how we relates this function cache with JIT ? Thanks Regards Sri.
