Fixed by change.

What are the reasons this was marked as a 4.3 regression?  I'm interested
when the regression occurred since the backend has never forced function
labels to memory in this code.

A simpler testcase is:

[EMAIL PROTECTED]:~/gcc_test$ less pr34525.c
extern void tramp_r ();
int is_trampoline_r (void* function)
{
  void *tramp_r_address = &tramp_r;

  if (!(((long)function & 3) == 2))
    return 0;

  return
   ((((long *) ((char*)function - 2))[0] == ((long *)
((char*)tramp_r_address-2)
)[0])
    && ((((long *) ((char*)function - 2))[2]) == (long)((char*)function - 2 +
16
))
    ? 1 : 0
   );
}
