Hi Óscar, Thank you for your prompt reply. Unfortunately, I still need more guidance as using the Demo page to generate C++ code didn't result in a global variable being used. Basically, I'm following your advice to use a LoadInst: Value *v = new LoadInst(result, "", theBasicBlock); Function *myfn = cast<Function>(v); I was not sure how I could get a BasicBlock for the

Hello, I'm not sure what I am trying to do is possible. I'm trying to create two modules, and call a function in one module from another module. First, a reassurance that I'm not trying to do something completely off the wall would be nice as I don't see any tutorials that do this. Second, any help getting this to work would be wonderful. Thanks, Aaron In my code, you'll

Hi Kirill, Don't forget to add X86TargetMachine.obj (add to Additional Dependencies in Linker options, if you are using MSVS) otherwise LLVM will try and use Interpreter instead of JIT.

To fix it, I think you want to add a declaration telling the compiler to treat some_test_func()

Hello Everyone, I am trying to create two modules in LLVM, where first module contains the definition of a function, gcd in this example and another module contains a call to this function. My example is based on the following tutorial, with a few changes. http://llvm.org/releases/2.6/docs/tutorial/JITTutorial2.html When I execute the verifier pass on my modules, it complains that the

I am new to LLVM API. and I am experimenting with it. I want to create Global Variables in a module. I am able to create local variables using IRBuilder class. I tried using GlobalVariable class to create global variables. but it doesn't work. my code looks like this: Module* mod = new Module("test", getGlobalContext()); Constant* c = mod->getOrInsertFunction("main",

Thank you very much for you help, Renato! I read through paper you referred and also this document - http://llvm.org/docs/tutorial/JITTutorial1.html Following these instructions to create successful function I run into some problems: 1) llvm::getGlobalContext() does not exists anymore? "llvm/LLVMContext.h" too? 2) creating instance of IRBuilder don't require template (from tutorial

Hello all; So my goal is to insert some (self-written) function calls in the LLVM IR. I can achieve it with a ModulePass and using the getOrInsertFunction() call. For a ModulePass I follow the steps- 1. Compile the code (in which call instructions are to be inserted) to LLVM IR 2. Compile the file (which contains the *called* external function ) to LLVM IR 3. Link them together and run the

Hey Valery, before we add this to the CVS repo, can you take a look at some of the changes I made to your HowToUseJIT example and

Hi all, I have some questions on some strange behavior I'm seeing with LLVM JIT in a multithreaded application. If this is the wrong forum for questions like this, I apologize, and please redirect me. The setup of the application is a singleton instance of a static Compiler object, which maintains local copies of an LLVM Module, JIT ExecutionEngine, and FunctionPassManager with registered

Hi I get huge memory leaks using LLVM IRBuilder (trunk version) Basically I recreate a function over and over again, and pretty sure that my code doesn't cause the leak while(true) { Function *fn = module->getFunction(name); if (fn) fn->eraseFromParent(); fn = cast<Function>(module->getOrInsertFunction(name, fnType)); fillFunction(fn); //Fill function with

Hi, I created a global char array, char buffer[1024]. I want to call a function to append the string information to the buffer repeatedly. For example, I need to implement the following code, where length, a, b, c, are global variables. int length = 0; length += sprintf(buffer+length, "str%d", a); length += sprintf(buffer+length, "str%c", b); length += sprintf(buffer+length,

Hi, I am trying to generate LLVM code that calls a "native" function in the parent program (the program hosting the JIT). I think that I have figured out how to do this, but I get the following assertion failure when the LLVM code is executed: ../llvm/lib/Target/PowerPC/PPCJITInfo.cpp:206: failed assertion `ResultPtr >= -(1 << 23) && ResultPtr < (1 << 23)

Apologies for the noop question in advance (just getting started with LLVM), and I'm not entirely sure if this is the right list to post to. is it? I have some lambda functions as member variables that I want to have my LLVM language make calls to. I've added a mapping to them, but this doesn't seem to enable LLVM to resolve the functions. I asked on stackoverflow but the suggestion
