--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Regarding (a): I think we should consider to simply use the same structure of
arrays ("struct array_descr_info") also for scalars. Besides that it already
exists, it is probably also sensible when we will handle coarrays, cf. PR49566.
(d) We also need to handle DW_AT_allocated/associated for CLASS, which means
that the variable's DW_AT_allocated must point to <var>._data.data instead of
to <var>.data.
