           Summary: LICM doesn't update alias sets correctly
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Loop Optimizer
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: alenhar2 at uiuc.edu


LICM doesn't update the alias sets with all the new instructions it inserts. 
See LICM::sink for examples.  Allocas and loads are created without being placed
in the Alias set tracker.  The results of the loads should alias the old values
they are replacing.
