[1/3] Improve and stabilise sort of member functions
Commit Message
From: Giuliano Procida <gprocida@google.com>
The functor virtual_member_function_less_than did not take into
account linkage name which can be the only difference when multiple
destructors with differing mangled names are present.
This change adds a check for linkage names and also flattens the
control flow in the comparison method to make the logic clearer.
Lastly, this change also uses std::stable_sort, in case all that
remains is insertion order.
* src/abg-ir.cc
(virtual_member_function_less_than::operator()): Name
temporaries like offsets and symbols to reduce repetition;
test each pair of elements (including symbol presence) and
return immediately if there's a difference; add a comparison
of linkage name just after comparing symbol names.
(sort_virtual_member_functions): Use stable_sort instead of
sort.
* tests/data/test-read-dwarf/PR22015-libboost_iostreams.so.abi:
Update with new ordering of member functions.
* tests/data/test-read-dwarf/test22-pr19097-libstdc++.so.6.0.17.so.abi:
Likewise.

I don't think it is "odd", it is simply an empty location expression,
which is defined as no location known.

The actual code change looks correct, but I would like the comment to
not say they are invalid (if they were dwarf_getlocation would have
returned an error), but that an empty location expression represents an
unknown location (and so it is indeed not very useful).
See also DWARFv5 2.6.1.1.1 Empty Location Descriptions
An empty location description consists of a DWARF expression
containing no operations. It represents a piece or all of an object
that is present in the source but not in the object code (perhaps
due to optimization).
Cheers,
Mark

You are right. I will use the 'empty location expression' terminology
instead.

I dropped the "invalid" wording everywhere after your last comment, but
forgot to change this very line :-/

Oops ,I didn't notice the email notification telling me about the list

Thanks. In the future, I think you can just keep sending the patches to
the list. I should be able to make them move through the pipe once I
receive the notification from mailman.
Applied to master!
