int a = 0;
int b = 0;

void foo(void)
{
  asm (".long %1-%0" : : "i"(&a), "i"(&b));
}

Of course, in a real program you would be using '%1-%0' as the
argument to some instruction, or something.  Or perhaps the rest of
the program is pic, but the asm is going to be non-pic for performance
reasons.

I admit it's a pretty bizzare example, though.
