This information is "held" by the computer on the "activation stack" (i.e., inside of each functions workspace). Every function has its own workspace PER CALL of the function

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.
