WebApr 6, 2024 · We know compilers like gcc can do lots smart optimization to make the program run faster. Regarding functions call optimization, gcc can do tail-call elimination to save the cost of allocating a new stack frame, and tail recursion elimination to turn a recursive function to non-recursive iterative one. gcc can even transform some … 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.
