The easiest way might be to use llvm-gcc and have it emit llvm IR for your sample code.  This works for just about anything.

That said in your case what you want appears to be a non-varargs version of printf.  In this case you'd need to create a special "printf" that only took the two arguments you want and then call it.

I'm not sure why you're doing this so much more is a bit difficult since I'd be guessing.
