           Summary: X86 isel problem with flags
           Product: libraries
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Backend: X86
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: sabre at nondot.org


The graph input to -view-isel-dags looks ok.  The dag input to -view-sched-dags does not.  It looks 
like something bad is happening with flags.

define void @test(i128* %A, i128* %B) {
        %C = load i128* %A
        %D = load i128* %B
        %E = add i128 %C, %D
        store i128 %E, i128* %A
        ret void
}

$ llc t2.bc -o - -march=x86 
ScheduleDAG.cpp:153: failed assertion `OpVT != MVT::Flag && "Flagged nodes should be in same 
sunit!"'
