/* PR 15262.

   The alias analyzer only considers relations between pointers and

   symbols.  If two pointers P and Q point to the same symbol S, then

   their respective memory tags will either be the same or they will

   have S in their alias set.

   However, if there are no common symbols between P and Q, TBAA will

   currently miss their alias relationship altogether.  */
