// reduced testcase, compile with -O2 -fpeel-loops -ftree-vectorize :

void foo (double *d)
{
  unsigned int a, i;
  double t[2];
  
  for (i = 0; i < 2; i++)
    {
      for (a = 0; a < 2; a++)
        t[a] = d[a];
      
      while (i)
        for (a = 0; a < 2; a++)
          d[a] = t[a];
    }
}
