similar to: [LLVMdev] [vmkit]Problems when modifying J3

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

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 want to add more complex

Hi Nicolas, it looks like there are missing things $ more lib/j3/LLVMRuntime/LLVMRuntime.inc // Generated by llvm2cpp - DO NOT MODIFY! Module* makeLLVMModuleContents(Module *mod) { mod->setModuleIdentifier("<stdin>"); // Type Definitions // Function Declarations // Global Variable Declarations // Constant Definitions // Global Variable Definitions // Function

Still the same. Is there any chance that the placement of my directories are causing this? Also the exact command that fails is /home1/public/zakkak/java/vmkit/Release+Asserts/bin/vmjc -std-compile-opts -load=/home1/public/zakkak/java/vmkit/Release+Asserts/lib/MMTKRuntime.so -load=/home1/public/zakkak/java/vmkit/Release+Asserts/lib/MMTKMagic.so -LowerMagic

Hi Fovios, Do you have a ./lib/j3/LLVMRuntime/LLVMRuntime.inc file being generated? What does it contain? Nicolas On Thu, Jun 7, 2012 at 5:47 PM, Foivos S.

Hi Nicolas, I finally found the root of the problem. Build was unable to locate llvm-build because it was looking for it in path/to/vmkit_src/utils/llvm-build while it was located in path/to/llvm_src/utils/llvm-build Actually llvm-build's path is defined by the path/to/llvm_src/Makefile.rules and looks like this LLVMBuildTool := $(PROJ_SRC_ROOT)/utils/llvm-build/llvm-build however in

Hi Minas, I tried recompiling Classpath with -fno-omit-frame-pointer, and now, instead of printing an error message, j3 just segfaults in "j3::JnjvmClassLoader::loadClassFromAsciiz(char const*, bool, bool) ()" I ran llcj under strace and found that it is not even opening the input or output files, but is otherwise running normally.

Hi Fivos, I cannot reproduce on my machine (ubuntu 64bit, clang/llvm/vmkit on svn trunk). What's your configuration?

Hi Nicolas, Thanks for all your help, but if 64-bit systems are still a big problem, perhaps the VMKit AOT compiler is not the best solution to my problem. I'd like to be able to support the major (if not all all) platforms that the Avian JVM supports - x86 & x86_64 linux & windows, powerpc darwin and ARM.

Hi all, I hope this is the correct place to post such questions? I am building vmkit for the first time, following the instructions on the get_started page (with one deviation: in step 4 I ran ./configure in my vmkit directory and therefore did not need to cd at the start of step 5. Is this correct?). Build platform is 64-bit CrunchBang Linux 11 "Waldorf", based on Debian Wheezy. I

Hi Joshua, If you can get a running 32bit system, I'd suggest you do so, as you'll get up to speed right away. I can't test VMKit on a 64bits machine, and I have been aware that there are some compilation/execution problems. Besides, the current GCs of VMKit do not work on 64bits (neither MMTk nor GCMmap2).

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

I'm trying to build the SVN version of VMKit and I'm getting this error while building. I have llvm and clang built from SVN too.

Hi, My machine is running Ubuntu server 64-bit And the revision from the trunk is 158095 for llvm, clang and vmkit llvm configuration ../../llvm/configure --enable-doxygen --enable-optimized --disable-jit vmkit configuration ../../llvm/vmkit/configure --with-llvmsrc=/home1/public/zakkak/llvm/ --with-llvmobj=/home1/public/zakkak/java/llvm/

Hi Nicolas, I thought MMTk is written in java and it is compiled by javac. retried a clean build with JIT enabled llvm configuration ../../llvm/configure --enable-doxygen --enable-optimized --enable-jit vmkit configuration ../../llvm/vmkit/configure --with-llvmsrc=/home1/public/zakkak/llvm/ --with-llvmobj=/home1/public/zakkak/java/llvm/
