           Summary: SelectionDAG extends constants
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Common Code Generator Code
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: alenhar2 at uiuc.edu

The selectionDAG will generate things like constant 0 -> zero_extend_inreg ->
users.  It probably should generate constant 0 -> users as most ways of loading
0 to larger registers will zero the register.
