Maybe?
- I am wondering how other debuggers (gdb mainly) will react to the new attribute. It would be great if "tuning" for lldb didn't completely break other debuggers as well
- speaking of tuning, I believe we currently don't "tune" Google binaries for lldb, so if this is conditioned on -glldb and we still emit the long attribute for gdb, then this will not change the size difference you were seeing. We probably should start tuning for lldb, but I don't know what will all of that cause (in particular it could cause a size *increase* due to some extra attributes emitted this way, but I don't think the difference should be big). I don't think this is Michael's problem, I'm just saying...
