Yes: placeholder expressions are supposed only to refer to the type allowed
by the context. I updated the message to talk about the context and I added
another one for the (invalid) case when want_address == 0.
I meant that

as if both context_type and base_decl were NULL_TREE?
Absolutely: done.

I mean, DW_OP_push_object_address isn't meaningful in all DWARF contexts,
in some it is forbidden, in others there is reall

Jakub,
First, thank you very much for reviewing this set of patches.
I think it's better to start with an answer to your last mail:

What kind of more complex expressions do you need and why?
GNAT can produce array types that make sense only as par

Hi!
I'm currently working on improving the debug information output for GNAT
(the Ada frontend in GCC), which currently uses non-standard DWARF to
describe complex types. Lately, I focused on debug information for
arrays and the attached inter-dependent patches are an attempt to do so:
