From df-core.c:
  free (problem_temps);

  i = NUM_FIXED_BLOCKS;
  FOR_EACH_BB (bb)
    {
      BASIC_BLOCK (i) = bb;
      bb->index = i;
      i++;
    }

  gcc_assert (i == n_basic_blocks);

  for (; i < last_basic_block; i++)
    BASIC_BLOCK (i) = NULL;


Now look at cfg.c:compact_blocks...  df-core.c should use that function
instead of duplicating it.
