--- Comment #9 from Paul Robinson <paul_robinson at playstation.sony.com> ---
The -gdwarf-N option implies -g, which appears to match gcc behavior,
as of Clang 6.0.

I used -gdwarf-3 because it isn't anyone's default, and -g1 because
gcc does not recognize the -gmlt or gline-tables-only spellings.
I tested back to clang 4.0 (don't have anything older handy).

-gdwarf-3 -g1
    clang <= 5.0: line tables v2, stub info v3
    clang >= 6.0: line tables v3, stub info v3
    gcc 7.4.0   : line tables v2, stub info v3

-g1 -gdwarf-3
    clang <= 5.0: line tables v2, full info v3
    clang >= 6.0: line tables v3, full info v3
    gcc 7.4.0   : line tables v2, full info v3

Marking as fixed.
