/* Free and compute again all the dominators information.  */

static inline void
recompute_all_dominators (void)
{
  mark_irreducible_loops ();
  free_dominance_info (CDI_DOMINATORS);
  free_dominance_info (CDI_POST_DOMINATORS);
  calculate_dominance_info (CDI_DOMINATORS);
  calculate_dominance_info (CDI_POST_DOMINATORS);
}
