[LLVMdev] How to get a return type of a function with LLVM-C API

[Matthijs Kooijman]

Hi Syoyo,

From my memory, this info is stored in the function type, so you could look at
the function's type and get the info there.

Looking the the API docs [1], I find that there is a simple method on Function
called getReturnType(). You should thus be able to do:
	Type* rt = F->getReturnType();

Good luck,

Matthijs
