I don't understand this question - these are C++ declarations, not
LLVM declarations (not to mention LLVM IR doesn't have "variables", as
such). So what's the actual LLVM entity you're dealing with?

Have you tried compiling some code with Clang to see what IR it
produces for different types, calls, and passing?
