[Bug rtl-optimization/20728] Wrong evaluation order of expressions in combine_reloads() in reload.c

[pinskia at gcc dot gnu dot org]

------- Comment #1 from pinskia at gcc dot gnu dot org  2006-09-03 20:01 -------
reg_overlap_mentioned_for_reload_p checks for psedu registers:
      /* If this is a pseudo, it must not have been assigned a hard register.
         Therefore, it must either be in memory or be a constant.  */

      if (regno >= FIRST_PSEUDO_REGISTER)
        {
          if (reg_equiv_memory_loc[regno])
            return refers_to_mem_for_reload_p (in);
          gcc_assert (reg_equiv_constant[regno]);
          return 0;
        }


So is this really an issue?
