The first two cases are optimized as expected.

The third one is wrong.  Here is mostly likely what Andrew Pinski meant to say.

void
t2 ()
{
  int i;
  int x;
  for (i = 0; i < 100000000; i++)
    {
      int t = (
      {
	int j = i;

	if (j < 100000000)
	  j = 1;
	else
	  j = 0;
	j;
      }
      );
      f (t);
    }
}

which is again optimized as optimized.
