--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
For my reduced testcase we get at optimized:
```
void func_1 ()
{
  <bb 2> [local count: 1073741824]:
  g_4 = g_2;
  g_4.f0 = 0;
  return;

}


void func_2 ()
{
  <bb 2> [local count: 1073741824]:
  g_4 = g_2;
  g_4.f0 = 0;
  return;

}
```
