Look at what is in <llvm source root>/examples/Kaleidoscope/toy.cpp. This is the final version of the tutorial and worked the last time I played with 2.6.

Hi, I'm investigating adding LLVM JIT support to a project of mine, but I'm having issues when trying to compile the Kaleidoscope tutorial* under MSVC 2008. In particular, the problem is that in main() when this line is executed > // Create the JIT. > TheExecutionEngine = ExecutionEngine::create(TheModule); create returns null, because both JITCtor and InterpCtor are null. I found this comment in ExecutionEngine.h > // To avoid having libexecutionengine depend on the JIT and interpreter > // libraries, the JIT and Interpreter set these functions to ctor...

I have a function in llvm ir as follows: def [2 x [3 x double]] @fun() { return [ ... ]; // a [2 x [3 x double]] constant } I would like to JIT this function in C. I first get the void pointer using: void *FPtr = TheExecutionEngine->getPointerToFunction( func ); Then I need to conver this void pointer to the corresponding C function pointer type, and then call the function pointer. double a[2][3]; CType *FP = (CType*) FPtr; a = FP(); My question is that: 1. Is this JIT work flow supported by LLVM? 2. If yes,...

First, you have to call llvm-g++ to use the llvm-gcc front end, but it doesn't matter here. I'd like to suggest that you use pastebin to put your code and the send us the link, so that we can download it. The problem is that TheExecutionEngine is set to NULL (maybe because of a previous error), but it will be really better if you use pastebin.
