WebApr 30, 2012 · A tail call is just the situation where you call a function and immediately return its return value as your return value. In this case, we don't need any of the state of the current code any more - we are just about to throw it away and return. The tail call optimisation throws away this unneeded state before calling the new function, instead ... WebWe do not intend to cover the complete feature-set of C++, or any other language.

WebDec 15, 2024 · This is tail call optimization. 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.
