[LLVMdev] Please add .o writer example to next release

[Nathan Jeffords]

this is function I use to emit an object file:

void output_object (llvm::Module * Module, llvm::TargetMachine * Target,
llvm::raw_ostream & Output)
{
    llvm::formatted_raw_ostream fOutput (Output);

    FunctionPassManager Passes(Module);

    Passes.add(new TargetData (*Target->getTargetData()));

    if (Target->addPassesToEmitFile(Passes, fOutput,
llvm::TargetMachine::CGFT_ObjectFile, llvm::CodeGenOpt::None))
        throw std::runtime_error ("bad voodoo
(Target->addPassesToEmitFile)");

    Passes.doInitialization();

    for (llvm::Module::iterator I = Module->begin(), E = Module->end(); I !=
E; ++I)
        if (!I->isDeclaration())
            Passes.run(*I);

    Passes.doFinalization();
}
