First of all thanks for fast replay. I appreciated it:-)

Yes my compiler is written in C++ and I had followed tutorial you
mentioned.

Yes I am generating LLVM IR and dumping it to, so far only, .s file using
my compiler. Other two modules are already manually written so I need the
one that I generate to link with other two and run. And this was precisely
my question about. Is it even possible to do so? Can I generate only one
module, link it with other two and run, everything on the fly in my
compiler? It will be like glued everything together in one binary file
(compiler), all phases: compiling, linking, running using single binary.
From your answer I partially assumed that it is possible. Can you
recommend me some other tutorial or sample code?
