WebDec 15, 2024 · Tail call optimization happens when the compiler transforms a call immediately followed by a ret into a single jmp. This transformation saves one instruction, and more importantly it eliminates the implicit push/pop from the stack done by call and ret. And your compiler does it all the time, not just for recursive function calls. WebMay 22, 2024 · This means that you can recur, but you must do it only in the tail position of the function call which means the recursive call the last thing called as the return value. C++ has a highly optimizing compiler that can actually optimize away the recursion in this case, making tail recursive functions more performant than non-tail recursive ones.
