/* For a MEM rtx, the alias set.  If 0, this MEM is not in any alias
   set, and may alias anything.  Otherwise, the MEM can only alias
   MEMs in a conflicting alias set.  This value is set in a
   language-dependent manner in the front-end, and should not be
   altered in the back-end.  These set numbers are tested with
   alias_sets_conflict_p.  */
