@Urgau have you started cargo part of this? I can help do that if you haven't.

@Urgau have you started cargo part of this? I can help do that if you haven't.

No, I haven't and to be honest I'm not sure when or if I would have done it any time soon.

It is now in the queue for this repository.

MacOS (and all apple targets) have -Csplit-debuginfo=packed as default instead of "off" like all other targets (well there is Windows, but we don't test it in those tests), also -Csplit-debuginfo is not stable on all targets so we only set in on Darwin where is matters.
