Thanks for the suggestion, that looks reasonable. I've updated the patch to also print the name and version of the first valid  (whose debug_info is non-empty) input DWO.

And about 'the most recently parsed' version, since its version might happen to match the current DWO version, which could be confusing to the user(since the internal logic uses the first DWO as the baseline)? It also seems to complicate the logic slightly.
