Therefore job for compilers is to identify … 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.

Web(Curiously, you can always transform an iteration into a recursion, and vice versa, although the code may get nasty.) Sadly, my version of the gcc compiler doesn't seem to do the tail recursion optimization anymore on 64-bit machines, possibly due to the new stack alignment rules, although it used to this optimization reliably on 32-bit machines. WebJun 24, 2015 · Just as a reminder, Tail Recursion is an optimization performed by the compiler. It is the process of transforming certain types of tail calls into jumps instead of function calls. My conclusion was that tail recursion is not handled properly by the Visual C++ compiler and a possible explanation could be the presence of a bug.
