            Bug ID: 35643
           Summary: [X86] Multiple output instructions should warn if all
                    outputs aren't scheduled
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: X86
          Assignee: unassignedbugs at nondot.org

Bug #35636 is due to MULX64rr giving 2 outputs, but the scheduler model
InstRW<> definition only poorly supports multiple outputs. We need a better way
to report when not all outputs are tagged by the scheduler class.
