Hello,

> So struct foo has changed and the second half of struct boo has changed.
>
> abidiff treats 2 of the 6 changes as harmless. Is this intentional?

The two changes that are flagged harmless are these:

        type of 'foo& lref1' changed:
          referenced type 'struct foo' changed, as reported earlier
        type of 'foo&& rref1' changed:
          referenced type 'struct foo' changed, as reported earlier

They are actually "redundant" changes, meaning, the changes to struct
foo have already been reported earlier.  So these changes are just being
left out of the report for "compactness", thus, hopefully, better
legibility.

So yes, that is intentional.

Cheers,
