in the following code control is not going into pragma functions. Please clarify, why the control is not going inside

Question

#include <stdio.h>
void f1();
void f2();

#pragma startup f1
#pragma exit f2

int main()
{
    printf("i am in main\n");
    return 0;
}

void f1()
{
    printf("i am in f1\n");
}

void f2()
{
    printf("i am in f2\n");
}

Answer 1

As explained over here,
The pragma is compiler dependent, gcc doesn't recognize startup/exit pragma. 
Similar behavior can be achieved via attribute in gcc.
Here is sample code.
