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.
