That’s fair. Can you at least try to describe what you’re trying to do and the data types involved in this? > GetNonSyntheticValue() returning self is correct behavior if IsSynthetic() == > False; but if there really is a synthetic provider attached to the object, > IsSynthetic() should definitely return True > > > Whose IsSynthetic() is supposed to return True,- the parent's or the child's? > What do you mean with this? The model is that you have an SBValue, and that SBValue could be backed by a synthetic value. If you want, you can LLDB not to prefer synthetic values - which changes the way the current SBValue works - or for the same backing variable, give you a non-synthetic SBValue, which is what GetNonSyntheticValue() does Parent/child should have nothing to do with this, unless I am misunderstanding you > And on which object should I be calling GetNonSyntheticValue()?
