In my main function after generate the code and before start the execution via JIT I do this: ExecutionEngine *EE = EngineBuilder(M).create(); string str = EE->getTargetData()->getStringRepresentation(); str[0] = 'e'; M->setDataLayout(str); if (verifyModule(*M)) { errs() << argv[0] << ": Error building the

Why are you changing the data layout to be little-endian?

Hello, I'm trying to catch assembly output and do some formatting for its presentation while being executed. I face a problem, which is clear from the error, although I have no clue on how to do it otherwise. If generating the code for its asm output and then for jit execution I get: ********** static llvm::MachineFunction& llvm::MachineFunction::construct(const llvm::Function*, const

Hi, I'm experimenting with using LLVM to generate dynamic FFI bridges in VisualWorks Smalltalk. LLVM is an amazing thing! I'm going from dynamically generated assembler source to machine code, and I have that all working, copied from the llc tool and the JIT example. I have two questions: 1. What optimization passes, if any, should I run on the module before I pass it to the

Hi, I'm using LLVM 2.4 (but llvm-gcc 2.2) on Ubuntu 8.10 (Intrepid Ibex) for a small part-time project combining Witty (http://www.webtoolkit.eu) and the ExecutionEngine in LLVM. (This is my second week with any of these so I still lack a lot of basic knowledge.) Sometimes I want to call a function returing a struct (in this case std::string), thus hasStructRetAttr() is true for the Function

Hi, I want to use a function defined in c(++)-code from code generated by llvm. For this I use ExecutionEngine.addGlobalMapping(). I started with the JIT execution engine and everything worked, then I switched to the interpreter engine and it stopped working, but only if compiled on a Linux system. More precisely it works if I use llvm 3.8.1 + gcc (Linux) + JIT llvm 3.8.0 + mingw-gcc

Hello everyone, i’m using LLVM (updated to 3.1 after seeing that bug, but it’s the same with 3.0) for running a bitcode on a C++ program, and Clang for compiling it. My code work perfectly, as expected on x64, but crash on x86. I’m on Windows 7 x64 and LLVM + Clang was compiled using Visual Studio 2010 (tested in both Release and Debug build). Project was make using CMake. Here is my code:

I got bit by this in LLVM 2.4 DagCombiner.cpp and it's still in trunk: SDValue DAGCombiner::visitSTORE(SDNode *N) { [...] // If this is a store of a bit convert, store the input value if the // resultant store does not need a higher alignment than the original. if (Value.getOpcode() == ISD::BIT_CONVERT && !ST->isTruncatingStore() && ST->isUnindexed()) {

Hi Óscar, Thank you for your response. I did not explicitly optimize the IR. I compile and run the two versions with ... GenericValue gv = EE->runFunction(bsqr, args); ... GenericValue gv2 = EE->runFunction(cppnat, args); I am calling method runFunction of ExecutionEngine. I am using the default code gen optimization level. Best regards, Nurudeen.

Hi folks, just installed the new llvm 1.9 build and noticed that my code no longer worked. It seems something has changed with addPassesToEmitFile(). First, the arguments to that method changed so that it no longer takes a PassManager, but only a FunctionPassManager. Instead there is a addPassesToEmitWholeFile() method, but that is marked as optional, and when I change my code to

Valery, Your JIT sample program has been added to projects/HowToUseJIT. I have defaulted the license to the standard UIUC license. Let me know if that's not okay and I'll fix it. If you continue to work on this (providing a command line option to use either interpreter or JIT would be nice), please provide patches against these files and I'll commit them for you. Here's the

Dear all I am trying to get the size of an LLVM pointer type. getPrimitiveSizeInBits() returns 0 for it and the documentation for isSized() suggest to use TargetData. I figured out from Kaleidoscope example that one can get a pointer to TagetData object through the execution engine but it seems to be an overkill. What is the right way to do it? Best regards, Victor -------------- next part

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

Hi everyone. I am using LLVM 2.4 release to practise the tutorial at Kaleidoscope Chapter 4. I built the LLVM library, and created my own project, and then paste the code from the tutorial into my own project. Then after compiled and built it, I passed the built stage. (I am using visual studio 2005 ) However, when I tried to input some code in the command line window, the sample program crashed.
