No MULTIPLE CALL TO SEGMENT warning where it should be...

Alexander Sorockin

Please consider the following code.

//--- module main.c ---

...

void main() {
        ...
        set_status_word(...);
        ...
}

//--- module can.c ---

...

void CAN_int_handler(void) interrupt 7 {
        ...
        set_status_word(...);
        ...
}

//--- module utils.c ---

...

void set_status_word(...) {
        ...
}

If you replace the calls to set_status_word() with calls to printf(), the linker issues a "multiple call to segment" warning, but, like this, this code causes no warnings. Why not? I looked at the assembler output of the set_status_word() function and noticed that it isn't using absolute register addressing. Can this relate somehow?
