How this works is that alongside any function arguments, there’s an invisible argument2 passed that contains the position of the instruction where it made the jump to the top of the function. The compiler knows what the instruction address is—it’s the one that puts it there—and so for each function call site, that’s just a static piece of information that gets passed in. At the end of each function, the compiler just has to generate some code to read that argument (usually stored in a CPU register somewhere, but it doesn’t have to be), jump back to that location, and continue execution.
