[OT] Prevent linker from unnecessary symbol resolution

[Srikanth Madani <srikanth.madani@xxxxxxxxxxxx>]

Hi,

Suppose I have a C file fun1.c containing two functions:

__________
void func1() {
        printf("\nIn function func1()\n");
}
void func2() {
        func3();
}
___________

and another called hello.c containing:

___________
void main() {
          func1();
}
___________

Is it possible to create a staticly linked binary using just these two
source files? Or do I have to provide a function definition for func3(),
even though it is not called.

Cheers,
