FYI, Tony Tye and his team at AMD created a DWARF Proposal for heterogeneous
debugging, which is generally useful but required to debug optimized code for
GPUs. It directly addresses the issue of how to model different address spaces
and makes location descriptions first-class objects that can be push onto the
evaluation stack.

AFAIK, these changes will be made to LLVM and there is interest in adding to
the DWARF standard eventually.
As mentioned in the past, I would be pleased to see proposals submitted
for these changes.
I would like to avoid the situation where we have an informal proposal
lacking specific changes to the DWARF standard, matched with an
implementation which claims to match the proposal. That's the opposite
of standardization.
