--- Comment #7 from Segher Boessenkool <segher at gcc dot gnu.org> ---
This is related to the compiler saving the return address for noreturn
sibcalls, like in
void g(void) __attribute__((noreturn));
void f(void) { g(); }
Maybe we should have an option like "-fimprove-debugging-experience" that
defaults to true only for -O0 and -Og (and maybe -O1)?
