[cfe-dev] Get mangled names C++

[Frank Fuchs]

Ok good to know (about the name mangling on Windows & the rest).
Now concerning the static linkage. I'm using the DynamicLibrary stuff of llvm to declare the function to the clang-compiled module like this 

	llvm::sys::DynamicLibrary::AddSymbol(symbolName, (void*)testCall);
	
        llvm::Type* r = (llvm::Type *)llvm::Type::getVoidTy(*context);
	llvm::FunctionType *ft = llvm::FunctionType::get(r, false);
	
	llvm::Module* module=new llvm::Module("global",*context);
	llvm::Function *f = llvm::Function::Create(ft, llvm::Function::ExternalLinkage,mangled_name, module);

it is inspired by this code http://github.com/speveril/eggengine/blob/master/src/script_LLVM.cpp (may be the author is around here as well).
