Hi all, I am currently working with vmkit (especially on J3) for a student project, I want to made some experimentations on J3. I see in the file lib/j3/VMCore/JavaClass.h that if I want to add some attributes in the class JavaClass I must change a few thing in LLVMRuntime/* and in JnjvmModule.cpp. But JnjvmModule.cpp does not exist anymore. So my first question is : what is the equivalent of JnjvmModule.cpp right now ? Secondly, I also want to add attributes in...

Hi Julien, I found out what was missing for adding a field to JavaClass. While precompiling Java code (JavaAOTCompiler) we create an equivalent LLVM Constant object for each class. So modifying the internal representation of a class means that you also have to modify the AOTCompiler. Here is a patch with a tiny example where an int is added to JavaClass. If you wan...

Hi Julien, I also tried to add a field and get the same error as you. In theory, to add a field in JavaClass or JavaCommonClass you have to put your field at the end of the declaration list (in order to minimize index changes in J3Intrinsics) in C++ code and in LLVMRuntime/runtime-single.ll We are working on this issue to see what is going wrong. The problem is the fact that the error is not determinis...

Sure: I'm on 64-bit Ubuntu Linux 10.04 with gcc 4.4.3. I followed the instructions on http://vmkit.llvm.org/get_started.html, as near as I can tell. I configured llvm with the default configuration: ./configure I configured vmkit with: ./configure --with-llvmsrc=/home/jowarner/code/llvm/ --with-llvmobj=/home/jowarner/code/llvm/ --with-gnu-classpath-glibj=/usr/share/classpath/glibj.zip
