--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
Smaller testcase from other PR, still needs the C++ FE

struct S { unsigned short x, y; } m = { 0, 0 };
void __attribute__((noipa)) bar() {}
void __attribute__((noipa)) baz()
{
  __builtin_exit (0);
}
void foo()
{
  while (1)
    { 
      unsigned int nrn_pass_num = m.x + 1;
      for (unsigned int nrn_idx = 0; nrn_idx < nrn_pass_num; ++nrn_idx)
        bar();
      baz();
    }
}
int main()
{
  foo();
  return 0;
}
