[PATCH] D11635: DebugInfo: Emit DW_AT_address_class for non-0 address space

[David Blaikie]

Hey Duncan - what's this "extraData" field intended for? Is this a
reasonable use of it?

I imagine we just want to extend the schema here to explicitly include
address space?

Could we instead extract it from the value we're describing? (probably not?
if the address happens to be a constant or something (which I guess is more
likely in custom address spaces) it wouldn't be carrying explicit address
space info?)
