‘noreturn’ function does return

Question

When I compile the C program below, I get this warning: ‘noreturn’ function does return. This is the function:

void hello(void){
  int i;
  i=1;         


        

Answer 1

Most probably, the function is marked with __attribute__((noreturn)). However, it does in fact return (when control reaches the end of irs body, since it doesn't enter an infinite loop, it doesn't call other "noreturn" functions, etc.)

I don't see what your point is in 1. marking the function as non-returning, 2. writing a function that does nothing - probably you could just eliminate both?
