similar to: [LLVMdev] Importance of VMKit JIT function cache

Hi Gael I am sorry that I couldn't explain what I was trying to say, anyway I've got the answer :) . In the *parseFunction* method returns *llvmfunction* pointer of compiled method and then it will be stored in to cache. Could you please more elaborate on how those machine instructions ( native functions) executing by llvm. I was trying trace and I couldn't able to find

Hi All I am trying to trace the execution path of J3 jvm with input of java byte code . Once java byte codes compiled in to llvm IR it will be passed to VMKit for store them . I couldn't find out which function is getting this Jitted output from *Functioncache* and executing them ? because , VMKit doesn't have an implementation of llvm Executionengine's *runFunction*

Hi Does anybody use *StartJnjvmWithJIT* from jvjvm.cpp in VMKit? Becuase , I am looking to use without JIT when we are running the Java byte code. My concern is StartJnjvmWithJIT getting three argument *int argc, char** argv, char* mainClass* - why we need to pass *argv and mainclass* arguments here? please help me on this. Regards Sri. -------------- next part -------------- An

That's a good point.  But it's worth noting that recompileAndRelinkFunction() and freeMachineCodeForFunction() are both vestiges of the old JIT (i.e. the "JIT" as opposed to the "MCJIT").  The old JIT is no longer actively supported. -Phil On April 26, 2014 at 9:47:05 AM, Sri (emdcdeveloper at gmail.com) wrote: Hi Fillip                  Addition to my previous

Hi, I am wondering how I can get the JIT'd llvm IR during VMKit execution. I am stuck in precompiling phase (when loading library classes), and I am facing various problems. If I can log the JIT'd llvm IR (from Java bytecode), that would be convenient. I turned on --enable-debug, but it doesn't seem very helpful at this stage. Any other suggestion is welcome. Thanks very much.

Oups, sorry for the mistake, llcj (not llc:)) is not more maintained!

Hello again Gaël, (et al) More on rekindling work on VMKit! Thank you for your interactions thus far on- and off-list. As you suggested in your VMKit-retirement email (to which I'm attempting to respond), I'm interested in producing a Java-to-LLVM compiler out of VMKit. I'd like to take you up on your offer to help understand the architecture. If I can get the a Java-to-LLVM

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 existing code except where necessary, such as name mangling and MMTkObject

Hi Nicolas, I found a 32bit Lucid machine (but it'd be great if there was a working 64bit version though). Everything was checked out this morning. I now am able to build vmkit with this configuration: ./configure --with-llvmsrc=/home/zoewolk/RESEARCH/llvm --with-llvmobj=/home/zoewolk/RESEARCH/llvm --with-gnu-classpath-glibj=/home/zoewolk/RESEARCH/classpath-0.97.2/lib

Hi Filip Thank you for your detailed explanation, I was actually looking to implement an adaptive approach which is basically when some function executed more frequently, I was trying to drop that function and compiled and linked with new optimized function. I just did the following - whenever some function executed more times , I called-back to program, so I that I

Hi Yi, The precompiler is in charge of translating 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

Hi, I'm new to VMKit and I'm trying to use its AOT Java compiler but I'm immediately getting an error message which I don't understand. Everything was compiler as suggested in the Getting Started tutorial, using GNU Classpath. I try to run: llcj ../../tools/trainer/Release+Asserts/HelloWorld.class and get the following output: Can not materiale a function in AOT mode.0

Hi Currently , I have doing some experimental work by using llvm, Is it possible to drop the machine code once it has been generated for particular function while program executing. For example some *void test(int)* function has been executed on native machine , I want to drop the code before I start execute some other function in my long running program. Thanks. With regards Sri.

Thanks, Anton. I always forget about llvm-admin :). I'd say converting all branches would be best, would help track the MCJIT work for example. Gaël, does that sound good to you? You're the one making all the commits these days :). ~Will On Sun, Jan 5, 2014 at 9:03 AM, Anton Korobeynikov <anton at korobeynikov.info> wrote: > Hello > > I can create a mirror, this is not

Hi all, So, MCJIT is working with vmkit, that's great. However, I need to retrieve the GCModuleInfo and the MachineCodeEmitter used during the compilation process. And I don't know how I should proceed? I'm trying to understand how they are preserved with the old jit, but I have to say that I'm a little bit lost because I haven't a global view of the code... So, any help would

Hi, I got lots of "undefined reference" when building vmkit. Anyone can help to give a solution? I download vmkit with "svn co http://llvm.org/svn/llvm-project/vmkit/trunk/", followed the instructions of "http://llvm.org/svn/llvm-project/vmkit/trunk/README.TXT", and built vmkit on ubuntu 13.10 x64 with sunjava 1.6.0_45 + llvm 3.3 + classpath 0.99 + gcc 4.8.1.

Hi all, Don't suppose VMKit could be added to the set of subprojects with official git mirrors? Please and thank you! :) ~Will

Hi, I kindly request some help here, am working on some open projects in VMKit! Do you know if there is an easy way to completely disable JIT and interpret the code instead? -- *Best Regards,* *David Daharewa Gureya* *E: gureya.daharewa at gmail.com <gureya.daharewa at gmail.com>* *Quick Links: www.c4dlab.ac.ke <http://www.c4dlab.ac.ke> | http://sci.uonbi.ac.ke/

Yes ! Thank you a lot :) It seems vmkit bytecode is quite close to the classic LLVM, but still adaptations to the passes have to be done ________________________________ From: Tim Northover <t.p.northover at gmail.com> To: Alexandru Ionut Diaconescu <cyrusthevirus001x at yahoo.com> Cc: "llvmdev at cs.uiuc.edu" <llvmdev at cs.uiuc.edu> Sent: Wednesday, June 26,

Hi Alexandru, The Java bytecode does not give and use the name of the local variables. We can find them in an attribute used for debugging, but currently, vmkit do not use this attribute. It means that the llvm bitcode that vmjc emit does not contain these names. Finding local variables names could be useful, but we don't plane to implement this feature for the moment... If you are
