Hi Akshat, Did you compile LLVM before compiling VMKit? libLLVMLinker.so is a shared library from LLVM.

Hi, I was just curious if VMKit development is still going on. Also while building VMKit I am getting error at link stage: make[1]: Entering directory `/code/vmkit/tools/vmjc' llvm[1]: Linking Debug+Asserts executable vmjc /usr/lib/gcc/i686-pc-linux-gnu/4.4.5/../../../../i686-pc-linux-gnu/bin/ld: cannot find -lLLVMLinker collect2: ld returned 1 exit status I have installed but I am not able

...ranslating the most common classes of the Java runtime library to llvm code (typically, java.lang.Object), in order to natively compile these classes and decrease the bootstrap time. So, if you have a segmentation fault at this stage, it means that you have broken something in the interface between MMTk and VMKit. If it can helps you: * during a first stage, we compile VMKit and J3 with a fake MMTk (we replace gcmalloc by a simple malloc) * we use the generated VMKit/J3 to natively compile MMTk * we link this code with VMKit and replace malloc by the gcmalloc of MMTk. At this stage, you have VMKi...

Hi, I replaced the MMTk code with a C-version MMTk code (I have been working on such AOT compiler for a while). The compiler should deal with most of the MMTk code base correctly - at least I get marksweep running with a tiny client). So I am trying to put the C version MMTk back with VmKit. I tried not to change much...

Hi, I'm trying to sort out how MMTk is linked with VMKit. MMTk is written in Java and VMKit is written in C++, and there are some java files and something seems to be garbage collection in c++ sources. Could you tell me where exactly mark and sweep algorithm takes place in (java?) source code and how and where is it invoked in c++?...
