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

Hi, Thanks a lot for the help! I am getting some errors though: I am on a 32 bit chroot on a x86_64 system. Thus llc guesses the wrong architecture from the module bitcode and spits out x86_64 assembly. I fixed this by adding "-march=x86" to the llc options in llcj. gcc doesn't know what -lgc is. I'm guessing it is the garbage collection library. How can I get it or
