--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
   /* Disable -freorder-blocks-and-partition when unwind tables are being
      emitted for Darwin < 9 (OSX 10.5).
      The strategy is, "Unless the user has specifically set/unset an unwind
      flag we will switch off -freorder-blocks-and-partition when unwind tables
      will be generated".  If the user specifically sets flags, we have to
      assume they know why.  */
