So I succeeded  in using a "PATypeHolder" for the "opaque" type, define a Type* with PointerType::getUnqual, prepare a field,  then use " refineAbstractTypeTo " to built the real type with this added field.

The thing is that I would need to do that repeatedly, that is progressively adding fields, generates code that access those ready fields, and "refine" the type step by step.

Is that even possible?

Thanks
