similar to: [LLVMdev] Which function executing VMKit's llvm-IR

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 VMKit JIT has a function cache to store compiled IR code , so, as soon as method is compiled , it will be stored in to function cache. My question is , who will use this compiled information from function cache. Since we are jitting , the llvm translate source code in to native code and executing them . So, how we relates this function cache with JIT ? Thanks Regards Sri.

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.

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

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 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.

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 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.

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

Neat approach, I think. So you set PassManagers's Opt level rather then ExecutionEngine's one? Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab, Institute of Information Science, Academia Sinica, Taiwan (R.O.C.) Tel:886-2-2788-3799 #1667 Homepage: http://people.cs.nctu.edu.tw/~chenwj

Dear LLVM guys, I am getting an error with my pass implementation, and I cannot figure it out. Basically, I've implemented part of a register allocation algorithm, but I am having problems to set the passes correctly. For instance, for this program below, the following error message is produced: .c ----------------------| .bc ---------------------------------

I have some LLVM IR after the optimization passes defined in createStandardModulePasses with the optimization level set to 3. It contains what appears to me to be an easily optimizable branch statement. In particular, note in the code below that at the end of the "loop" BasicBlock that there is a conditional branch where in the false case, it branches to the label

Hello, I'm writing a virtual machine that functions as a sandbox based on llvm. In order to prevent programs from accessing memory that has not been allocated to them, I want to replace calls to malloc and free with calls to a logged functions that will record the memory that is being allocated to the program. Is it possible to cast/convert a MallocInst or FreeInst to a CallInst? Thanks,

Sorry for the unnecessary list mail. No problem, this is a better way to go. The MallocInst and FreeInst instructions are about to be removed from LLVM IR.

Is it possible to get llvm to generate native machine code without using gcc and friends ? Do I use lli ? I'd like to directly create executable code that i can stick in memory somewhere and jump into (call). (I'm looking to use llvm in a BSD licensed project). Simon. -- Simon Burton, B.Sc.

I have an external function that was added with ExecutionEngine::addGlobalMapping... and the JIT is burning the wrong address into the emitted function. All of the addresses have 0xffffff8d00000000 added to them. Does this look familiar to anyone? I'm using 2.6 on Solaris10/x64 if it matters. This has been working for about two months and I can't readily figure out what I changed to break
