+        Introduce an "internal" parameter.  In the flat representation of
+        a class for internal purposes, always use the prefix "class" even
+        if this is a struct.
+        (get_type_name): To build an internal name for a
+        reference or pointer to an anonymous type, consider the namespace
+        name of said type.
+        (equals): In the overload for decl_base, take the namespace name
+        of anonymous decls into account when comparing them.

+        Bug 26780 - Fix array subrange bounds (de)serialization
+        * src/abg-reader.cc (build_subrange_type): Read lower-bound
+        attribute if present.  Then try to read upper-bound attribute as
+        well.  If this is not an infinite subrange assert that the length
+        must be equal to the difference between the bounds.
+        * src/abg-writer.cc (write_array_subrange_type): Write the
+        lower-bound if it's present and not zero.  In that case, write the
+        upper-bound as well.
+        * tests/data/test-diff-pkg/hdf5-1.10.6-2.fc33.x86_64.rpm: Add new
+        binary test input.

+        source distribution.
+        * tests/test-diff-pkg.cc (in_out_specs): Add the binary test input
+        to the set of --self-check tests.

+2020-11-25  Dodji Seketeli <dodji@redhat.com>
+
+        abipkgdiff: Avoid uncertainty when sorting worker tasks
+        * elf_size_is_greater: Take the name of the binaries into account
+        when their size is equal.  Also, assert that all comparison tasks
+        have compared binaries.
+
+2020-11-25  Dodji Seketeli <dodji@redhat.com>
+
+        tests/data/test-fedabipkgdiff: Update reference output
+        * tests/data/test-fedabipkgdiff/test7-self-compare-from-fc23-dbus-glib-report-0.txt:

+
+2020-11-24  Matthias Maennich <maennich@google.com>
+
+        abipkgdiff: minor cleanups
+        * tools/abipkgdiff.cc: remove unused using statements
+        (self_compare_task): remove shadowing members and delegate
+        construction to base class.

+2020-11-23  Dodji Seketeli <dodji@redhat.com>
+
+        dwarf-reader: support artificially generated translation units
+        * configure.ac: Detect if we are running on RPM >= 4.15.  If yes,
+        then define the preprocessor macro RPM_4_15.  If that macro is
+        defined then test-diff-pkg.cc can support RPMs from Fedora >= 31
+        as those are compressed with zstd.  Earlier RPM versions don't
+        support that compression scheme.
+        * src/abg-dwarf-reader.cc (build_translation_unit_and_add_to_ir):
+        Suffix the offset of the translation unit to its name when that
+        name is "<artificial>".
+        * tests/data/test-diff-pkg/mesa-libGLU-9.0.1-3.fc33.x86_64.rpm:
+        New binary test input.
+        * tests/data/test-diff-pkg/mesa-libGLU-debuginfo-9.0.1-3.fc33.x86_64.rpm: Likewise.
+        * tests/data/test-diff-pkg/mesa-libGLU-9.0.1-3.fc33.x86_64.self-check-report-0.txt:
+        New reference output for the binary test input above.
+        * tests/data/Makefile.am: Add the new test inputs above to source
+        distribution.
+        * tests/test-diff-pkg.cc (in_out_specs): Add the binary test
+        inputs above to source distribution if we are running on an RPM
+        version >= 4.15.

+
+        fedabipkgdiff: make --self-compare use abipkgdiff --self-check
+        * tools/fedabipkgdiff (abipkgdiff): If the user provides the
+        --self-compare options, generate the abipkgdiff command by using
+        the --self-check option.
+        (run_abipkgdiff): Each return value of the abipkgidiff runs can be
+        negative because they are unsigned values in essence, but as
+        python doesn't seem to have a unsigned integer type.  So we need
+        to consider the max of the absolute value of the return codes
+        here.
+        * tests/data/test-fedabipkgdiff/test7-self-compare-from-fc23-dbus-glib-report-0.txt:
+        Adjust.
+
+2020-11-19  Dodji Seketeli <dodji@redhat.com>
+
+        abipkgdiff: Add a new --self-check option
+        * tools/abipkgdiff.cc (options::self_check): Define new data
+        member.
+        (options::options): Initialize it.
+        (display_usage): Add help string for the --self-check option.
+        (parse_command): Parse the new --self-check option.
+        (extract_deb): Add missing newline.
+        (compare): Remove useless white space.
+        (compare_to_self, self_compare_prepared_userspace_package)
+        (self_compare_prepared_package, compare_to_self): Add new static
+        functions.
+        (class self_compare_task): Add new class.
+        (prepare_package): Add a new overload that takes just one
+        parameter.
+        (elf_size_is_greater): Don't crash if the args are empty.
+        (main): If the --self-check option is given, make sure we have
+        just one package in argument.  Use the new compare_to_self
+        function to handle the --self-check option.
+        * doc/manuals/abipkgdiff.rst: Add documentation for the new
+        --self-check option.

+
+        Bug 26769 - Fix missing types in abixml output

+        lookup_canonical_type}): Remove functions.
+        * src/abg-ir.cc (type_eligible_for_odr_based_comparison): Remove
+        static function.
+        (type_base::get_canonical_type_for): Don't perform the ODR-based
+        optimization for C++ anymore.
+        * src/abg-reader.cc
+        (read_context&::maybe_add_var_to_exported_decls): Don't add a
+        variable that hasn't been added to its scope.  Otherwise, it means
+        we added a variable that wasn't yet properly constructed.  Also
+        add a new overload for var_decl_sptr&.
+        (build_var_decl): Do not add the var to its the set of exported
+        declaration before we are sure it has been fully constructed and
+        added to the scope it belongs.
+        (build_class_decl): Only add *static* data members to the list of
+        exported declarations.
+        (handle_var_decl): A var decl seen here is a global variable
+        declaration.  Add it to the list of exported declarations.
+        * src/abg-writer.cc (write_context::decl_only_type_is_emitted):
+        Constify parameter.
+        (write_translation_unit): Do not forget to emit referenced types
+        that were maybe not canonicalized.  Also, avoid using noop_deleter
+        when it's not necessary.
+        (write_namespace_decl): Do not forget to emit canonicalized types
+        that are present in namespaces other than the global namespace.
+        * tests/runtestslowselfcompare.sh.in: New test that compares
+        libabigail.so against its own ABIXML representation.
+        * tests/Makefile.am: Add the new test runtestslowselfcompare.sh to
+        source distribution.  This test is too slow to be run during the
+        course of 'make check'.  It takes more than 5 minutes on my slow
+        box here.  Rather, it can be run using 'make check-self-compare'.
+        I plan to run this before releases now.

+
+        Make sure to canonicalize all types but decl-only classes

+        (build_function_type): Use the new
+        build_ir_node_for_variadic_parameter_type.  It takes care of
+        canonicalizing variadic parameter types.
+        (build_function_decl): Canonicalize the function type that is
+        created here.
+        (build_ir_node_from_die): Use the overload of
+        maybe_canonicalize_type which canonicalizes class_or_union nodes
+        directly, rather than the one which handles DIE offsets.  The
+        latter was used as an optimization to reduce the size of the array
+        of types scheduled for canonicalization, as DIE offsets take less
+        space than pointers to IR types.  Now that we have DIE
+        de-duplication, my bet is that we can do away with the former.
+        And that also ensures that we miss no type for canonicalization
+        purposes.
+        * src/abg-reader.cc (build_array_type_def): Canonicalize the

+        Fix spurious new lines after diff sections.
+        * src/abg-default-reporter.cc (report): In the corpus_diff

+
+        Correct various inconsequential typos.
+        * src/abg-leaf-reporter.cc (report): In the class_or_union_diff
+        overoad, swap calls to report_mem_header to match the rest of the
+        code.
+        * src/abg-reporter-priv.cc (represent): In the var_diff_sptr
+        overload, add some missing whitespace; remember we've emitted the
+        pretty representation in 2 cases where this was omitted (though 1
+        of these is the last case where it makes no difference).
+        maybe_report_diff_for_symbol Add some missing whitespace; remember

+        where this was omitted, also affecting the return value of the
+        function (but no caller cares).
