Hi everyone, I've just checked in a JVM and a CLI for LLVM (called JnJVM and N3). Both are placed in the vmkit svn directory. You can find the source code here: svn co http://llvm.org/svn/llvm-project/vmkit/trunk vmkit Its licensed under the U of I Open Source License, so now that's in svn, you can change whatever you want, as long as HelloWorld.java and HelloWorld.cs work ;-) I

Very nice Torok! I applied most of the patch. A few comments: 1) What is your jni.h file? I can't compile the Jni.cpp file with your changes. 2) ISO C++ does not support %jd. x86_64 does not know about %lld? Thanks!

Dear developers, Are there any benchmarks for the performance of Java Native Interface (JNI) calls in VMKit? Since VMKit is based on LLVM which can also run C++ code (maybe in the same just-in-time compiler?) I guess calls from Java to C++ and back could be much faster than in Sun's JVM which has extremely slow C++ -> Java callbacks. If this was the case, this would be a big advantage of

I looked into the archives as far back as 2009 and searched around for more information about vmkit, but I still have some questions. First of all, what is that status of VMKit? Is there any active development? A roadmap? Is it in maintenance mode? Secondly, can VMKit generate binaries that can be used on android/jni? Finally, I understand that the .net/CLI support is no longer being

Hi Nicolas, thanks for your detailed answer! Now I understand the issues a little better. I'm going to install LLVM + Vmkit and try it out using JNI. Regarding the garbage collector, do you think that the Garbage Collection ABI of C++11 could be implemented in a way compatible to the JVM's garbage collector? http://www2.research.att.com/~bs/C++0xFAQ.html#gc-abi Perhaps this could make

VMKit runs multiple threads (for example for GC, finalization, etc), so I need the back trace of other threads as well :) Thanks!

Yes I did, one thing worth mentioning is on running configure for GNU Classpath towards the end this error is displayed and it crashes, I assumed it was okay and went to create the symbolic links and completed the rest of the process with vmkit mentioned in Getting Started as instructed: -I../../../native/jni/native-lib -W -Wall -Wmissing-declarations -Wwrite-strings -Wmissing-prototypes

Have you created the symbolic links to GNU Classpath .so? ie step 2 of http://vmkit.llvm.org/get_started.html?

Sorry if I'm repeating something that was already said. I was just thinking "why the heck do I seem headed for JVM generation if what I want to use is LLVM", and this is the result: I'm coming from a Java background. I'm using Eclipse, I'm used to the syntax highlighting, cross referencing and refactoring support that Eclipse offers. I know I will want to have the

Hi, I wanted to use VMKit project to convert Java Bytecode to LLVM IR bitcode. But I do not know how to start, since I came to know that VMkit is written for llvm -3.3 version, but I want it for latest LLVM version 6.0.1. So, could you please suggest me, whether I have to write it whole project from scratch to meet my requirement of latest llvm version, or can use existing project by building
