Hi, My application generates some LLVM assembly code which I then convert to IR code using ParseAssemblyString. If I have the following LLVM assembly code: define double @test() { ret double 1.230000e+02 } then, using ExecutionEngine::runFunction, I get a GenericValue return value which DoubleVal property is indeed equal to 123. So, all is fine there. However, if I have the

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 function!\n"; return 1; } vector<GenericValue> noargs; GenericValue GV = EE->runFunction(Main, noargs); o...

Hello all, As we work the last few bugs out of our project for the last release, we need to find a way to set the default datalayout of the LLVM Assembly file we are generating to be that of the host machine. I've seen options for target triples in the Doxygen but not the datalayout. BTW, we're using version 2.6 of LLVM. --Sam

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
