Hi, I am using visual studio 2008's generated solution file for clang/llvm. I was looking at the online demo where it gives out llvm2cpp program along with the llvm IR of the C code. I could not find any executable in the /bin directory for llvm2cpp. I was wondering if there is either source or executable of the llvm2cpp program that is used by llvm demo available for either llvm-2.7

After compiling llvm and the cfrontend, I tried to run llvm2cpp on a few of the .ll files in the test/Regression directory. When I try this, I get the following error: llvm2cpp: Invalid bytecode signature: 5552203B (Vers=0,Pos=4) Any help would be appreciated. thanks, Todd

Some time ago we reported a compile-time performance regression in the LiveIntervals analysis pass (see http://llvm.org/bugs/show_bug.cgi?id=18580). We detected it at first after migrating from LLVM 3.1 to 3.3, but the problem persists also in 3.5. This regression is especially critical when compiling long functions. In one of our benchmarks compile time goes from 200s (in 3.1) up to 1500s (in

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?

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

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

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

Hello Harris, Thank you for your answer. So it is there a way of annotating variables in Java Code, so I can see them into LLVM bytecode? Thank you !

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 :

What classpath implementation are you using ? GNUClasspath or OpenJDK ? Harris Bakiras On 06/17/2013 03:57 PM, Alexandru Ionut Diaconescu wrote: > Hello Harris, > > Thank you for your answer.

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

Hi All, Has vmkit been updated and tested with LLVM 2.8? I am unable to build it (llvm builds fine). There were some errors with Makefile.rules: $(Verb) $(LLVMAS) -f $(<F) -o - | $(LLC) -march=cpp -cppgen=contents -o $@ (march and cppgen options not recognized). What I cannot get past is this one (the warnings concern me as well): ... make[3]: Leaving directory

I am hitting an LLVM assertion from the llc tool iff the bitcode file is optimized at -O3 level by opt). -O1 and -O2 levels of opt do not cause this assert.

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 Harris, A question has arisen, what is the difference between VMKit2 and VMKit, and why, in the first place the new VMKit2 fork was been created?

Hi everyone, I am Harris Bakiras the new VMKit engineer. I followed the VMKit "Getting Started" instructions to install VMKit on my Linux Ubuntu 11.10 64-bit but I get the following error : make[1]: Entering directory `VMKIT_ROOTDIR/lib/Mvm/StaticGCPass' make[1]: *** No rule to make target `VMKIT_ROOTDIR/lib/Mvm/StaticGCPass/Release+Asserts/StaticGCPass.ll', needed by

To compile vmkit on Ubuntu 12.04 64-bit machine, I followed the steps giving here <http://vmkit.llvm.org/get_started.html>[1]. but when I run ./configure I am getting following error- root at komal:/home/komal/Desktop/GSOC/vmkit/vmkit# ./configure >> -with-llvm-config-path=../llvm-3.3.src/configure >> --with-gnu-classpath-glibj=/usr/local/classpath/share/classpath/glibj.zip

Hi Kumar, There is an error on your configuration line, you should provide the path to llvm-config binary instead of configure file. Assuming that you compiled llvm in release mode, the llvm-config binary is located in : YOUR_PATH_TO_LLVM/Release+Asserts/bin/llvm-config Try to change the -with-llvm-config-path option and it will compile.
