[PATCH] D103131: support debug info for alias variable

[David Blaikie via Phabricator via cfe-commits]

dblaikie added a comment.

Looks like GCC emits aliases as a `DW_TAG_variable` without a location, not as a `DW_TAG_imported_declaration` - what gave you the inspiration to do it in this way? (I think it's probably good, but DWARF doesn't lend itself to novelty so much... can be good to stick with how other folks already do things since it'll be what consumers already know how to handle)

How's this work if the alias target isn't declared in the source - but in inline assembly instead? (I guess GCC probably handles that OK, but the Clang strategy here might not cope with it)
