           Summary: DenseSet and DenseMap could use a swap function
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Core LLVM classes
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: alenhar2 at uiuc.edu
                CC: llvmbugs at cs.uiuc.edu


DenseSet::swap and DenseMap::swap don't exist, which makes it hard to use the
classes in situations which require efficiently moving map or set contents
between objects.
