similar to: [LLVMdev] Performance of JNI in VMKit

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

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

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

Greetings, I am searching for an alternative to sun's java implementation - one that is not under gpl.. I've been reading the vmkit code for JNI.. And I notice that it is not completely filled out yet... That's fine though, I see there is filled in function like most of the non implemented functions.. Couple of questions: Is the entire llvm required for java/cli vmkit to run?

I am working on a project to port JRuby on Embedded systems. JRuby converts Ruby code to bytecode which is executed by any JVM. For this project I am testing performance of JRuby with various available JVMs. I have chosen ARM architecture. Does vmkit support ARM architecture?

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

here <http://vmkit.llvm.org/> its mentioned that its portable on ARM. So simply cross-compiling will work?

Hi Nicholas, and thanks for the prompt reply...

Hello Kumar, Unfortunately we never experienced on ARM architecture and we are not planning to port VMKit on ARM for the moment.

Hi Kumar, It's a mistake, we will correct that, we haven't tested vmkit on arm. As LLVM supports arm, by cross-compiling vmkit in arm/linux, it could work, but you will probably have to adapt some few parts of the code. If you plan to make the port, feel free to send us a lot of patches :) Gaël Le 22 juil. 2013 17:09, "Kumar Sukhani" <kumarsukhani at gmail.com> a écrit :

I don't know how JRuby works, maybe it uses some new feature that GNU Classpath does not provide. VMKit's openJDK version is unstable on 64 bits since package version 6b27. You can still use it for very small programs which does not need GC but that's all. It works fine on 32 bits. So you can try it on 32 bits or revert your java version to a previous one (< than 6b27) to test

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?

Hi Harris Bakiras, Thanks for reply. It working now. Actually I wanted to try vmkit VM to run jruby codes. vmkit is able to run Java program, but when I try to run JRuby code then I get following error - root at komal:/home/komal/Desktop/GSOC/programs# jruby hello.rb > > Platform.java:39:in `getPackageName': java.lang.NullPointerException > > from ConstantSet.java:84:in
