[PATCH] D99850: [WIP/RFC] lld LTO drops variables in namespaces from .debug_names

[David Blaikie via Phabricator via llvm-commits]

dblaikie added a comment.

Yeah, that looks like it breaks the unattached-global.ll because this causes a DW_AT_location to be added (probably with some kind of broken/empty expression) for a variable without a location/that's been optimized away.

How's the index behavior compare to GCC's debug_names behavior under similar circumstances? Or llvm's behavior with a static (file-local) variable that's similarly optimized away?
