> A little background: I am very interested in this patch and I have been trying to get statistics with the resulting binary from this patch so I can evaluate if we want to use it in production on linked binaries produced by our build system. I'd like to see how long it takes to run and also how much smaller debug info becomes. If I run this currently I have no way to know if we are producing anything valid and wether or not I can log the results since we always produce something and have no exit status. I also can't trust the resulting debug info sizes at all since we might be removing all sorts of extra DWARF sections that the existing DWARF linker doesn't handle, or worse yet we just don't clone an attribute and we are missing inline debug info. So it is hard to evaluate this right now as it is. I do think we should try to return errors for files we can't handle though as it would be great if people trying this out could evaluate it and know if it is working for them or if there are things that aren't handled.

Ok, I will prepare followup patch implementing such a behavior.
