Pavel, this is pretty much exactly what happens. (Except that there is
no frontend. The substitution is done during CodeGen. But that is just a
detail)
I think a more general solution, that doesn't tie mulle-objc implicitly
to the dwarf format would be better in the long term though.

Pavel, can you say more about your idea?
In both ObjC and C++ methods, you can refer to an ivar either as "this->ivar"
or just "ivar". But the DWARF for C++ doesn't tell lldb that a particular
language supports referring to ivars transparently this way. It will say that

I think the cleanest solution would be to actually modify the compiler
to emit "correct" dwarf (as in, dwarf representing the code as it
actually looks like to user, and not some internal intermediate
representation). The dwarf expression in DW_AT_location can easily
handle the lookup of some field
Because we try as much as possible to let the compiler figure this sort of
thing out for us, we implement the transparent lookups for this & self by
compiling our expression in a context that poses as a method of the class whose
method we are stopped in. For instance, for ObjC, we construct a c
