Ah right, thanks for the explanation, still I think we can make `setIsNewDbgInfoFormat` a bit readable by
```
void setIsNewDbgInfoFormat(bool isNewFormat) {
    if (IsNewFormat == IsNewDbgInfoFormat) {
        return;
    }

    if (IsNewFormat) {
        convertToNewDebugFormat();
    } else {
        convertFromNewDebugFormat();
    }
}
```

Thought an early return make sense in terms of  if the requested format is the same as the current one
