llvm-nm does show the difference between two static functions (e.g., _print n the following example) with the same name. Is there a way of allowing it to show their differences (for example, the file where they are from)? Thanks.

==> main.c <== /* vim: set noexpandtab tabstop=2: */ #include <stdio.h> void print1(); static void print() { print1(); }
int main() { print(); return 0; }
==> print1.c <== /* vim: set noexpandtab tabstop=2: */ #include <stdio.h> void print2();
void print1() { puts("Hello World1!"); print2(); }
==> print2.c <== /* vim: set noexpandtab tabstop=2: */ #include <stdio.h> void print3();
static void print() { puts("Hello World2!"); }
void print2() { print(); print3(); }
==> print3.c <== /* vim: set noexpandtab tabstop=2: */ #include <stdio.h>
void print3() { puts("Hello World3!"); }
