The printing logic should be moved to `LVScopeRoot::doPrintDebugger(...)`
```
Error LVReader::printDebugger() {
  // Any additional printing checks.
  if (Error Err = createSplitFolder())
    return Err;

  return Root->doPrintDebugger(OutputSplit, OS, ...);
}
```
As the printing needs to take into account any possible `--output=split` that splits the view output by compilation unit.
