            Bug ID: 39244
           Summary: VPlan dot printer gets CondBit quotes wrong
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Loop Optimizer
          Assignee: unassignedbugs at nondot.org

                CC: llvm-bugs at lists.llvm.org

As of trunk, the VPlan dot-printer gets the quotes wrong when printing the
CondBit, ex:

  N1 -> N2 [ label="" lhead=cluster_N3]                                         
  subgraph cluster_N3 {                                                         
    fontname=Courier                                                            
    label="\<xVFxUF\> pred.load"                                                
    N2 [label =                                                                 
      "pred.load.entry:\n" +                                                    
        "BRANCH-ON-MASK %vp9752 = not %vp59984\l" +                             
         "CondBit: %vp9752 (if.end)\l

ie. it's missing the last quote, and dot complains:

$ dot tsvcs278.vplan.dig1
Error: tsvcs278.vplan.dig1: syntax error in line 137 near '"'

After adding the quotes to all occurrences, dot works fine.
