--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
What the code in crtstuff should do is something like:
char *end = __TMC_END__ ;
char *start = __TMC_LIST__ ;

asm("" :"+r"(end));
asm("" :"+r"(start));

...
  if (end - start == 0)
....

We have recommended this already in bugzilla for other cases like the above
too.
