        PR23641 - Type definition DIE matched by a supprspec but not its decl
        *definition* of T, they will be dropped too.
        We'll end up with those two libraries that are identical (modulo the
        order in which libabigail sees type declarations and their
        definitions) and are considered different when a suppression
        specification makes us drop T: the second library appears to
        libabigail as if T was removed from it.
        This is the problem addressed by this patch.
        When the definition of a type T is suppressed because it's considered
        private then we look if there was a forward declaration for it
        elsewhere, that is not matched by the private type suppression
        specification.  If we encountered such a type declaration then it
        means that declaration is in effect an "opaque" version of T.  So
        rather than just dropping T altogether, we keep (and build an IR) for
        its opaque version only.  And we drop the definition of T.
        This seems to fix the issue.
        I can't seem to reproduce the slight re-ordering of DIEs descriptions that
        uncover the issue so I'll rely on integration tests to catch future
        regressions on this issue, rather than on unit tests.  Sigh.

        type or a function parameter changed, then that's a local change
        for the current instance of function_type.  Likewise, in the
        overload for  function_decl, consider that a change in the textual
        representation of the function_decl is a local change.  Likewise,
        in the overload of function_decl::parameter, consider that a
        change in the textual representation of the parameter type is a
        local change.
        * src/abg-leaf-reporter.cc (leaf_reporter::report): Report leaf
        changes to functions.

        REDUNDANT_CATEGORY category to pointer diff nodes.
        * src/abg-ir.cc (equals): In the pointer_type_def overload,

        (translation_unit::bind_function_type_life_time): Adjust.
        (environment::priv::decl_only_class_equals_definition_): New data

        here, we can now consider that an unresolved class declaration
        compares different to an incompatible class definition of the same
        name.  So no need to look through decl-only classes in that case.
        (equals): In the overload for class_or_union, if
        environment::decl_only_class_equals_definition() is false, then an
        unresolved class declaration of name "N" compares different to a
        class definition named "N".

        Several fixes and enhancements to abigail::workers
        * Don't try to schedule a task if the pointer to the task is nil
        * Fix a data race when bringing workers (of a queue) down
        * Always try to wake up all waiting threads when bringing down queue
        workers.
        * Fix a data race when accessing the queue condition variable
        * Fix a data race when notifying listeners about the end of the job
        performed by the task.
        Enhancements
        ============
        * Pass the "task done" notifier by reference, to the worker queue.
        Without this, the worker queue needs to copy the "task done" notifier
        by value.  This implies that user code needs to provide task done
        notifier instances that come with potentially complicated copy
        constructors.  By passing it by reference and by just re-using the
        notifier from the user code, we do away with the need for copying
        altogether.  This also fixes some latent copying bugs.
        * Add a workers::queue::schedule_tasks() method
        This allows user code to schedule a vector of tasks at once.
        * make workers::queue::get_completed_tasks() return a non-const vector
        This enables user code to sort the completed tasks as they wish.
        * include/abg-workers.h (queue::tasks_type): New typedef.
        (queue::queue): Pass task_done_notify by reference.
        (queue::schedule_tasks): Declare new member function.
        (queue::get_completed_tasks): Return non-const vector.
        * src/abg-workers.cc (queue::priv::default_notify): New data
        member.
        (queue::priv::notify): Make this data member be a reference.
        (queue::priv::priv): Initialize the notify data member to either
        the new default_notify (if no notifier is provided by the
        constructor) or to the notifier provided by the constructor.
        (queue::priv::schedule_task): Do not schedule a nil task.  Update
        comment.
        (queue::priv::schedule_tasks): Add a new member function.
        (queue::priv::do_bring_workers_down): Update comment.  Protect
        access to "bring_workers_down" with tasks_todo_mutex to prevent a
        data race.  Call pthread_cond_broadcast on the queue_cond
        unconditionaly to prevent some worker threads to keep waiting for
        ever. Also, protect the access to the queue_cond by the
        queue_cond_mutex to precent a data race.
        (queue::queue): Pass the notifier by reference. Update comment.
        (queue::schedule_task): Update comment.
        (queue::schedule_tasks): Define new member function.
        (queue::wait_for_workers_to_complete): Update comment.
        (queue::get_completed_tasks): Return a non-const vector. Update
        comment.
        (worker::wait_to_execute_a_task): Update several comments. Make
        the execution of the notification code to be synchronized (on the
        tasks_done_mutex).

        (--drop-private-types): Document this new option.
        * src/abg-tools-utils.cc: Update copyright notice
        (handle_fts_entry): On the generated suppression specification, do
        not set the flag to drop matched types.  Also, don't match types
        defined in files which patch start with "/usr/include/".
        * tools/abidiff.cc (options::options): Initialize the
        drop_private_types data member to false.
        (display_usage): Remove usage string for

        --drop-private-types.
        (parse_command_line): Don't part --dont-drop-private-types,
        rather, parse --drop-private-types.

        generated, if --drop-private-types was provided, then instruct the
        suppression to drop matched types.

        package, but a package_descriptor because the latter carries the
        options.  So when the user used the --drop-private-types option,
        make the generated private types suppression to drop matched
        types.

        (write_function_type): Likewise.  Emit a new "method-class-id"

        A suppressed diff node implies suppressing all equivalent nodes too
        *class of equivalence* is visited once.  This is not only a way to
        prevent infinite loops while visiting the graph, but also an
        optimization as it avoids walking two equivalent diff nodes.
        But then it can happen that we forget to categorize some diff nodes
        inside a given class of equivalence, even though we categorized some
        others.
        This patch makes it so that when a diff node inside a class of
        equivalence is categorized as SUPPRESSED, the canonical diff node of
        that class of equivalence is categorized as SUPPRESSED too.  That way,
        to know if a diff node is suppressed, we just need to look at its
        canonical diff node.
        While doing this, I noticed that abidiff and abipkgdiff are not
        dropping private types from libabigail's internal representation, even
        though the Library now has that capability.  The patch fixes that.
        But then the patch adds a --dont-drop-private-types option to abidiff
        to avoid dropping those private types from the IR, so that regression
        tests can make sure that a suppressed diff node implies suppression
        all equivalent nodes too.

        (diff::priv::get_context): Convert the weak pointer to the context
        into a shared_ptr and return it.

        diff::priv::get_context() to access the context.
        (diff::context): Likewise.
        (corpus_diff::priv::ctxt_): Make this a weak_ptr.

        elf binaries take a diff context output parameter.  After the

        that it's life time is bound to the scope this function was
        called from.
        (pthread_routine_compare): Create a shared pointer to hold a
        reference on a diff context.  Pass that shared pointer by
        reference to the compare function that compares elf binaries.
        Rather than storing corpora in the reports_map, (as those corpora
        would then out-live the diff context and thus create memory
        corruption issues), emit the report directly into an ostringstream
        and store that stream in reports_map.
        (compare): In the overoad that compares packages, rather than
        trying to get corpora from the report_map, just emit the content
        of the ostringstream that is now there.

        Bug 19885 - Cannot associates a function DIE to a symbol on powerpc64
        *from* the address of its entry point.
        More precisely, on ppc64, the address of a function is the address of
        a function descriptor.  The function descriptor is a set of three 64
        bits addresses.  The first element of the triplet is the function
        entry pointer address.  So to get the symbol a given function entry
        point address belongs to, one must get to the function descriptor
        which contains said function entry point address.  And function
        descriptors are in the ".opd" special section.
        Unfortunately, Libabigail's  ELF/DWARF reader has no knowledge of all
        this.  So it cannot get the symbol of a given function DWARF
        description.  So it considers all functions as having no ELF symbols.
        So it shows no ABI change pertaining to function sub-types on ppc64.
        This patch makes Libabigail support function descriptors on ppc64 so
        it can detect changes on function sub-types there.

        Bug 19619 - failing to suppress added aliased function reports for C++
        * src/abg-comparison.cc
        (function_suppression::suppresses_function): Make the evaluation
        of the "name" and "name_regexp" consider the cases of languages in

        symbol alias names must be matched.  In the latter case, if "name"
        and "name_regexp" match the function name, the suppression
        specification is considered to match the report about the function
        change.  Also, use the elf_symbol::is_main_symbol() predicate to
        test for the symbol being a main symbol, rather than using

        Bug 19204 - libabigail aborts on DWARF referencing non-existing DIE
        * src/abg-dwarf-reader.cc (get_parent_die): If we couldn't find
        the parent of a given DIE, return false, do not abort.  Also,
        assert that if we don't find the parent of a DIE in the main debug
        info, we don't find it in the alternate debug info either (and
        vice versa).  This is because I'd like to abort on cases where we
        look for a DIE in the wrong debug info; those cases are likely to
        be hint that the DWARF reader is doing something wrong which ought
        to be investigated and fixed.

        vectors and identify pairs to be diffed. Put them in a vector and sort
        it by the summed ELF pair size. Spawn comparison threads and safely
        check for results in the proper order of the ELF pairs. Report any
        differences ASAP and collect the threads after all the reporting is
        done, checking their return status.

2015-10-17  Dodji Seketeli <dodji@redhat.com>

        Fix emitting of referenced type in abixml writer
        * Use of canonical pointers in the hash map of referenced types
        The abixml writer was using canonical types pointer values to hash
        referenced types in a map.  It was doing so "by hand"; and it was thus
        messing things up for types without canonical types (like some class
        declarations) etc.
        This patch changes that by using the generic solution of
        abigail::ir::hash_type_or_decl(), which also uses the same canonical
        pointer type values.  For types with no canonical types, that
        functions knows has to gracefully fallback.  At worst, it will just
        make things slower, not wrong.
        * Sorting of referenced types
        The patch also changes the sorting function used for the hash map of
        referenced types.  The previous solution was sorting the pretty
        representation of types; but then when two types have the same pretty
        representation (think, typedefs, for instance) then their relative
        position in the sorted result was random.  This causes some stability
        issues, in that emitting the abixml for the same binary several times
        can lead to the some types being sorted differently -- they have the
        same name, but not necessarily the same type *IDs*, as they are
        different types.
        The new sorting code handles this better; it also uses the pretty
        representations of types, when they are equal, it uses the type IDs to
        tell the types apart.  At least this brings stability in the abixml
        output, for a given binary.
        * Avoiding duplicating declaration-only types when emitting the
        context of referenced member types.
        We don't keep track of declaration-only classes that are emitted.
        This is because we allow a given class declaration (that carries no
        definition) to appear several times in a given ABI corpus.  So when a
        referenced type is a class declaration, it always appears as if that
        referenced type has not been emitted.  So when we specifically emit
        the not-emitted referenced types, it can happen that declaration-only
        classes can appear a lot of times.  This is unnecessary duplication,
        aka bloat.
        This patch thus introduces a new hash map that tracks emitted
        declaration-only classes, so that we can allow duplication of class
        declarations when they follow what's done in the IR read from DWARF,
        and disallow that duplication when it's totally artificial and
        useless.
        * Better tracking of referenced types
        We were blatantly forgetting to mark some referenced types as such.
        So those were missing in some abixml output.
        This patch fixes the spots where we were forgetting that important
        information.
        * Better representation of the scopes of the referenced types that
        were specifically emitted.
        The previous code was failing at properly representing the class scope
        of some referenced types that were specifically emitted, or sometimes,
        for member types, representing the scope would be so screwed that the
        (referenced) member type itself wouldn't be emitted at all.
        This is because I thought that to emit a given member type, just
        emitting its parent scope would be enough. I thought that would
        automatically trigger emitting the member type itself.  First, that
        would emit too much information at times; the other members of the
        scope are not necessarily needed.  And second the "duplication
        detection code" would sometime refuse to emit the scope class, because
        it has already been emitted earlier!  But the incarnation that got
        emitted didn't have this member type as member, then.  Yes, in DWARF,
        the same class A can be declared several times with different member
        types in it.  The complete representation of A would be a union of all
        those declarations of A that are seen.
        This patch addresses this issue by carefully emitting just the
        information that is needed from the scope of the referenced type.
        Basically the scope is declared just to declare/define the type we are
        interested in; period.  The abixml reader is now properly geared to
        re-construct the scope by merging its different parts that are now
        scattered around, in the ABI corpus.  That support is part of this
        patch set.
        instance, a member typedef would be emitted with the information of
        its parent class badly formatted.
        * src/abg-writer.cc (struct type_ptr_comp_functor): Remove this.
        (sort_type_ptr_map): Likewise.

        canonical type of the type to record as referenced directly.

        declaration-only classes that are emitted.
        (write_decl_in_scope): Use the new write_member_type_opening_tag
        and write_class_decl_opening_tag.  Now write class scopes
        ourselves; they only contain the type declarations that we are
        emitting.
        (write_translation_unit): Use the new sorting code to sort the
        referenced types to emit.  Do not emit referenced types that are
        declaration-only classes that have already been emitted.  Handle
        the fact that emitting the referenced types might make those
        emitted type *reference* other types too! So handle those new
        referenced types as such, and emit them too.
        (write_qualified_type_def, write_typedef_decl, write_var_decl): Do
        not forget to mark referenced types as such.

        Don't canonicalize types not added to their context in abixml reader
        * src/abg-reader.cc (read_context::maybe_canonicalize_type):
        Assert that a class type that is scheduled for canonicalization
        must be in a scope.  We do this only for classes, for now.  The
        assert here helped to spot (and fix)  a lot of places where we
        were canonicalizing types without scope.
        (read_context::build_or_get_type_decl):  Canonicalize types here,
        when they are built and (hopefully) added to their scope.  There
        might be cases here where we try to canonicalize types that are
        not added to their scope.  That should bomb in the assert above,
        at least for class types, for now.  We'll then fix the places where
        the types are created, to make them properly scoped.
        (build_type_decl, build_qualified_type_decl)
        (build_pointer_type_def, build_reference_type_def)
        (build_array_type_def, build_enum_type_decl, build_typedef_decl):
        Do not try to canonicalize the types early, right when they are
        created.  Canonicalization should happen at the point where (or
        after) they are added to their scope.
        (build_class_decl): Likewise.  Also, schedule member types for
        canonicalization once they've been added to their scope.
        (build_class_tdecl): Schedule the pattern of the class template
        for canonicalization once it has been added to its scope.  I am
        not sure I should do this, as the pattern is not yet a real type,
        but I am taking my bet.
        (build_type_composition): Schedule the composed type for
        canonicalization once it's been added to its scope.
        (handle_type_decl, handle_qualified_type_decl)
        (handle_pointer_type_def, handle_reference_type_def)
        (handle_function_type, handle_array_type_def)
        (handle_enum_type_decl, handle_typedef_decl, handle_class_decl):
        At this point, we should know if the type is to be added to a
        scope or not.  If it's in a scope, then schedule for
        canonicalization.

        of the parameters being set to the function: they start at 1,
        unless the first parameter is artificial, in which case its index

        type is constructed directly with the parameters passed as an
        argument to the constructor.

        Bug 18535 - abidiff reports false positive ABI difference for libstdc++
        *non-static* data member; a static data member only is not enough to
        make the class declaration become a definition.
        * src/abg-dwarf-reader.cc (build_class_type_and_add_to_ir): The
        presence of a data member shouldn't make a declaration-only class
        loose its declaration-only-ness; the presence of a enon-static*
        data member should.

        (type_base::get_canonical_type_for): For declaration-only classes,
        look at their definition for the canonical_type.  Do not use
        recursive type hashing anymore.  Rather, use the pretty
        representation string, and hash that.
        (class_decl::base_spec::get_hash): Do away with hash value caching
        here.
        (class_decl::operator==): For decl-only classes, look at their
        definitions for canonical types.
        (hash_type_or_decl): Adjust comment.  Use the canonical type
        pointer value for type hash.  That's the fast path.  Otherwise, if

        * src/abg-writer.cc (struct type_hasher): New hasher type.
        (type_ptr_map): Use a deep pointer comparison equal operator
        functor, and canonical types as type hash values.
        (write_class_decl): Do not write size and alignment on decl-only
        classes.  Do not record decl-only classes as being emitted.  Their
        definition must be emitted before.
        * tests/test-read-write.cc (main): Do not do abi testing on
        translation units (as opposed to doing it on abi corpora) as that

        context relation afterwards.  In add_data_member, when a data
        member changes its static-ness, move the data member into the
        class_decl::priv::non_static_data_members_ or out of it, as
        necessary.

        considered static.
        (set_member_is_static): Move this definition after the definitions

        automatically add the created decl to their context, and then
        update the properties of the resulting member decl later, just

        Use cache type hash values only after type canonicalization is done
        *when* we request that hash value.  If we are computing the hash value
        of struct list itself, then the temporary value of "struct list" is
        zero.  But then once we are done computing the hash value of "struct
        list", that value becomes non-zero.
        Hence, the hash value of a type depends on when that value is
        computed.
        But then if we want to cache that hash value and re-use it later,
        which value should we cache?  Definitely not the zero value!
        So in other words, we can use (and thus cache) the hash value of a
        given type T only after the hash values of all types which use T have
        been computed.
        To satisfy that condition, we decide to use the (cached) hash value of
        each type only after we've computed all the hash values of all types
        of the system.
        So, during type canonicalization, when a type T is canonicalized, this
        patch stores the hash value of T.  But then it's only when all types
        are canonicalized that the hashing code is allowed to re-use the
        cached value of types.
        This fixes the issues of spurious type differences introduced when the
        same type was read either from DWARF or from abixml.  Those
        differences where introduced by differences in the order of hashing
        types which sub-types refer to themselves. The patch also updates
        regression tests accordingly.
        * src/abg-dwarf-reader.cc (read_debug_info_into_corpus): Before we
        read debug info and build the IR, set a flag in the environment
        saying that type canonicalization isn't finished yet.  But then,
        after type canonicalization is done, flip that flag to say that
        type canonicalization is done.

        canonicalization has been done and if the type has a cached value,

        More type degradation fixes (from DWARF to abixml)
        * include/abg-fwd.h (get_type_scope): Declare new function.
        * src/abg-hash.cc (var_decl::hash::operator()): Do not cache the
        hash because that can alter the hash computing of a larger type
        which embeds a var decl as a member declaration.  This is
        especially true if the var decl indirectly references the larger
        type.  The only way to cache the value of a var decl would be to
        wait after all canonical types have been computed.  We'd then seal
        all types.  After that sealing happens, we can cache var decls
        starting from the top-level ones.
        (function_decl::hash::operator()): Likewise.
        * src/abg-ir.cc (get_type_scope): Define new functions.
        * src/abg-reader.cc (read_is_declaration_only): Declare this
        function earlier.
        (typedef const_types_map_it): Adjust this to make it point to a
        map of string and vector of types, as opposed to a map to string
        and type as it was before.
        (typedef types_map_it): New typedef.
        (read_context::map_id_and_node): Map a type id to the last
        xmlNodePtr that represent a *declaration*.  That gives more leeway
        to the declaration resolution code to choose the right definition
        later.  Otherwise, there are cases where the wrong definition.  By
        wrong definition, I mean a definition that is different from the
        one chosen by the DWARF reading code, for a given declaration.
        Basically for a given ABI corpus, a type declaration resolve to
        the first definition seen in the corpus.
        (read_context::get_all_type_decls): Define new member function.
        (read_context::types_equal): Use qualified names only if both
        types have a scope.
        (read_context::key_type_decl): Now a given ID is associated to
        *all* the declarations and definition that have that ID.
        (read_translation_unit_from_input): Make sure the current corpus
        node points to the right node.
        (build_class_decl): Resolve class declarations to the first
        definition seen in the corpus.  Key a type decl before reading its
        members as a reading a member can request the current decl.  No
        need to try and canonicalize a member type, as build_class_decl()
        does that already.

        Make test-read-dwarf.cc and test-read-write.cc abidiff the ABIs
        * tests/test-read-dwarf.cc (main): Use abidiff to compare the
        input elf file with the XML emitted.  That should yield the empty
        set.
        * tests/test-read-write.cc (main): Likewise, use abidiff to
        compare the input abixml file with the one that is emitted.

2015-08-29  Dodji Seketeli <dodji@redhat.com>

        Read abixml as a whole file and fix lots discrepancies with dwarf
        * src/abg-reader.cc (class read_context): Move data member at
        the top of the class like what is done elsewhere in the code
        base.
        (read_context::m_corp_node): New data member.
        (read_context::read_context): Initialize it.
        (read_context::{get,set}_corpus_node): New accessors.
        (read_context::map_id_and_node): Accept that a node id previously
        defined is defined again.  In that case we just remember the first
        mapping id -> xml-node.  That seems to work for now.
        (read_context::get_translation_unit): Fix the logic.
        (read_context::m_wip_types_map): Rename
        read_context::m_wip_classes_map into this.
        (read_context::clear_wip_types_map): Rename
        read_context::clear_wip_classes into this.

        into this.
        (read_context::types_equal): New member function.
        (read_context::clear_per_translation_unit_data): Do not clear
        anything anymore as the previous data that were per-tu are now
        per-corpus.
        (read_context::clear_per_corpus_data): Clear here the previous
        data that were per-tu.
        (read_context::maybe_canonicalize_type): Add a new force_delay
        flag that forces the type to be late-canonicalized.  Also force
        late-canonicalize references, pointers, qualified-type and typedef
        because they must be canonicalized once they've been added to
        their context; but then this function might be called too early,
        before they are added to their context.
        (read_context::type_id_new_in_translation_unit): Remove this
        member function.
        (read_translation_unit_from_input): Be able to either use the
        xmlTextReader interface, or get the current 'abi-instr' xml
        element node.  If using the xmlTextReader interface, use it to
        move to the 'abi-instr' node, expand it and then use that.  In
        either case, call read_translation_unit() with the 'abi-instr' xml
        element node.
        (read_translation_unit): Take an 'abi-instr' XML element in
        argument now, use that to read the translation unit, as opposed to
        using the xmlTextReader interface we where using before to walk
        the sub-tree of the abi-instr xml node.
        (read_context::get_scope_for_node): If the scope is a new
        translation unit, then build the new translation unit.
        (read_symbol_db_from_input): Take the function and variable symbol
        data bases, and read the current xml element node (do not use the
        xmlTextReader interface anymore) to populate the function and
        variable symbols.
        (read_elf_needed_from_input): Do not use the xmlTextReader
        interface anymore.  Rather, use the current xml element node, look
        for the 'elf-needed' xml element node and use it to populate the
        set of elf dependencies.
        (read_corpus_from_input): Rework to expand the contents of the
        corpus node and use the result, rather than just exclusively
        relying on the xmlTextReader interface.
        (build_function_parameter): Build a proper IR node for variadic
        parameters.  Build function type node *after* having built all the
        parameters IR, so that parameter indexing is the same as what is
        done in the DWARF reader.  Also, if the function is not being
        added to its context yet, then delay the canonicalizing of its
        type, just like what is done by the DWARF reader.
        (build_qualified_type_decl, build_pointer_type_def)
        (build_reference_type_def, build_enum_type_decl, build_type_decl):
        Adjust.  Do not enforce anymore that the ID of this type be new in
        the current TU.  Delay canonicalizing if the type is not being
        added to its context.  For typedefs, use an adapted way of
        checking the consistency of the underlying type.
        (build_array_type_def): Do not enforce anymore that the ID of this
        type be new in the current TU.  Support the fact that the array
        might not have any DW_AT_byte_size attribute.  Force late
        canonicalizing if the array is not being added to its context.
        (build_class_decl): Adjust.  Reuse the
        read_context::maybe_canonicalize_type() function rather than
        trying to determine locally when to canonicalize.
        (build_template_tparameter): Adjust

2015-08-29  Dodji Seketeli <dodji@redhat.com>

        Fix handling of class declaration during DWARF reading
        *virtual* member functions, data members, base classes or a
        DW_AT_byte_size as being conditions for being defined.
        * src/abg-dwarf-reader.cc (read_context::decl_only_classes_map_):
        Remove this data member.
        (read_context::{declaration_only_classes_to_force_defined,
        schedule_declaration_only_class_for_forced_resolution}): Remove
        these member functions.
        (read_context::resolve_declaration_only_classes): Do not force
        resolution of class declaration.
        (build_class_type_and_add_to_ir): Do not schedule classes for
        forced-resolution when they are used as base classes.  The
        presence of a member function is not enough to make the class be
        defined.  It needs to be a virtual member function.

2015-08-28  Dodji Seketeli <dodji@redhat.com>

        Fix important hashing issues
        * src/abg-hash.cc (class_decl::hash::operator()): Do not force
        base classes to have definitions anymore.  GCC and Clang (at
        least) some time emits debug info in which the definition of some
        base classes are missing, especially when those base classes have
        vtables.  In that case, the definition of the class might it's in
        the binary where the vtable is emitted, which might not be the
        binary we are looking at.  So let's relax the assertion we had
        here for base classes.  For hashing virtual member functions,
        directly walk the virtual member functions by looking at
        class_decl::get_virtual_mem_fns() rather than walking all
        member functions and looking for the virtual ones.  This is a
        speed optimization but it also helps during debugging.

        (class_decl::member_function_template::operator==): Avoid the
        static cast in the overload for member_base.  In the overload for
        member_class_template, avoid infinite recursion.
        (function_tdecl::operator==): In the overload for decl_base, do
        not do the real work here in the overload for decl_base Rather,
        the real work is done in the new overload for function_tdecl, and
        all other overloads call that one.

        * src/abg-ir.cc (class_decl::{set_size_in_bits, get_size_in_bits,
        get_alignment_in_bits, set_alignment_in_bits}): Define these
        virtual functions.

        Fix type lookup algorithm
        * src/abg-ir.cc (find_next_delim_in_cplus_type): Define new static
        function.
        (fqn_to_components): Use the new function above to break up a
        fully qualified name into components, rather than the too simple
        string::find_first_of() we were using previously.
        (lookup_node_in_scope): If the found type (class) is a
        declaration-only and if it has a definition, then return it.

        Make decl hashing always take qualified name into account

        overload.
        * src/abg-dwarf-reader.cc (build_class_type_and_add_to_ir): Rather
        than requiring that base classes be of class type, just require
        that they be compatible with class types.
        * src/abg-ir.cc (is_compatible_with_class_type): Define a new
        overload.

        get_member_function_is_{virtual,ctor,dtor,const}.

2015-08-25  Dodji Seketeli <dodji@redhat.com>

        Don't cache type qualified name before canonicalization
        * src/abg-ir.cc (decl_base::{get_qualified_parent_name,
        get_qualified_name}): Use the qualified name cache only if the
        type is fully built, i.e, when its canonical type is present.
        (qualified_type_def::get_qualified_name): Likewise.
        (pointer_type_def::get_qualified_name): Likewise.

        (corpus_diff::diff_stats_sptr): New typedefs.
        (corpus_diff::diff_stats::diff_stats): Make this constructor take

        * src/abg-comparison.cc (corpus_diff::diff_stats::priv::ctxt_):
        New data member.  This is a weak pointer to a diff_context.
        (corpus_diff::diff_stats::priv::priv): Take a diff_context_sptr
        and initialize the weak pointer ctxt_ to it.
        (corpus_diff::diff_stats::priv::ctxt): New accessor to the
        diff_context hold by the diff_stats.
        (corpus_diff::diff_stats::{num_removed_func_filtered_out,

        num_added_func_syms_filtered_out,
        num_removed_var_syms_filtered_out,
        num_added_var_syms_filtered_out}): If the user asked for the added
        [or removed] variables/functions/symbols to be ignored, the
        accessors for the number of filtered added/removed variables/functions/symbols
        return the total number of added/removed
        variables/functions/symbols; that is, say that *all* added/removed
        variables/functions/symbols got filtered out.
        (corpus_diff::priv::diff_stats_): Turn this data member into a
        [shared] pointer to diff_stats.
        (corpus_diff::priv::filters_and_suppr_applied_): Remove this data
        member.  Now that diff_stats_ is a pointer, we don't need this
        boolean anymore.
        (corpus_diff::apply_filters_and_suppressions_before_reporting):
        Adjust to the fact that filters_and_suppr_applied_ is gone, and
        that diff_stats_ is now a pointer.

        reporting with

        (get_typedef_diff_underlying_type_diff): Define new function.
        (type_suppression::suppresses_diff): After looking through the
        different kind of access methods, use the new
        type_suppression::suppresses_type(), rather than doing lots of
        stuff ourselves here.  But then, if the suppression doesn't apply
        to the subjects of the diff, look through typedefs and try to
        apply the suppression again.
        * src/abg-ir.cc (get_typedef_underlying_type): Define new
        function.
        * tests/data/test-diff-suppr/libtest25-typedef-v{0,1}.so: New

        (erase_created_temporary_directories_parent): New static function.
        (compare): After comparison, erase the temporary parent directory
        as well.

2015-07-24  Dodji Seketeli <dodji@redhat.com>

        Make the name of the removed variable section be consistent
        * src/abg-comparison.cc (corpus_diff::report): Introduce the
        section of removed variables with the string "Removed variable",
        rather than with the string "Deleted variable".
        * tests/data/test-abicompat/test2-var-removed-report-0.txt: Adjust.

2015-07-24  Dodji Seketeli <dodji@redhat.com>

        Consider default symbol versions when computing added/removed fns/vars
        * include/abg-corpus.h (corpus::{lookup_function_symbol,
        lookup_variable_symbol}): Take a elf_symbol::version object,
        rather than a string representing the version.  Add an overload
        that takes an elf_symbol.
        * src/abg-corpus.cc (find_symbol_by_version): New static function.
        (corpus::{lookup_function_symbol, lookup_variable_symbol}): Take a
        elf_symbol::version object, rather than a string representing the
        version.  Add an overload that takes an elf_symbol.  If the looked
        up symbol has no version and if the corpus contains a symbol with
        the same name and with a default version, then return that latter
        symbol if the corpus doesn't contain a symbol with the same name
        and empty version.
        * src/abg-comparison.cc
        (class_diff::ensure_lookup_tables_populated): Adjust.
        (corpus_diff::priv::ensure_lookup_tables_populated): Before
        deciding that a symbol has been added, if the symbol has a default
        version, make sure no symbol with the same name and without
        version was present in the former corpus.  Similarly, before
        deciding that a symbol has been removed, if the symbol has no
        version, make sure the latter corpus has no symbol with the same
        name and with a default version.
        * tests/data/test-diff-dwarf/test12-report.txt: Adjust.  The
        function should not be considered as added, because its symbol
        (and version) was already present in the former DSO.

2015-07-24  Dodji Seketeli <dodji@redhat.com>

        Fix a thinko in removed variables detection
        * src/abg-comparison.cc
        (corpus_diff::priv::ensure_lookup_tables_populated): Once we have
        computed a set of potentially deleted variables that turned out to
        contain variables that were actually *NOT* deleted, really take
        these into account by removing these false positives from the set
        of deleted *variables*.  We were trying to delete these from the
        set deleted *functions*; woops, I guess this was a copy & paste
        error.

2015-07-24  Dodji Seketeli <dodji@redhat.com>

        Fix logic of type_has_non_canonicalized_subtype()
        * src/abg-ir.cc (type_has_non_canonicalized_subtype): Once the

        the 'has_non_canonical_type' property.

2015-07-24  Dodji Seketeli <dodji@redhat.com>

        Fix style issues

        the comment of this type.
        * src/abg-dwarf-reader.cc (build_ir_node_from_die): Fix the
        filling of the text of the comment of the code that chooses to
        perform early canonicalizing.

2015-07-24  Dodji Seketeli <dodji@redhat.com>

        Adding member type doesn't reset declaration-only-ness of a class
        * src/abg-dwarf-reader.cc (build_class_type_and_add_to_ir):
        Adding a new member type shouldn't remove the
        declaration-only-ness of the class.

2015-07-22  Dodji Seketeli <dodji@redhat.com>

        Extract all packages for a given run of abipkgdiff under the same temp dir

        function, accessor.
        (package::package): Adjust to the new names of the data members.
        Call the new package::extracted_package_parent_dir() static member
        function to initial the package::extracted_dir_path_ data member.
        (package::{path, extracted_dir_path, type, is_debug,

        the data members.

        erase_extraction_directories}): Adjust.
        (erase_created_temporary_directories)

        (extract_package_and_map_its_content, prepare_packages, compare)
        (main): Adjust.

2015-07-22  Dodji Seketeli <dodji@redhat.com>

        Fix type synthesis to fix abicompat weak mode
        * include/abg-fwd.h
        (synthesize_type_from_translation_unit): Declare new function.
        (synthesize_function_type_from_translation_unit): Make the
        translation_unit parameter non-const because the function needs to
        bind the life time of the synthesized function to the life time of
        the translation unit.  Make this function be a friend of
        abigail::ir::translation_unit.
        (synthesize_function_type_from_translation_unit):
        * src/abg-ir.cc (translation_unit::priv::synthesized_types_): New
        data member.
        (synthesize_type_from_translation_unit): Define new function.
        (synthesize_function_type_from_translation_unit): Make the
        translation_unit parameter non-const.  If the return is void, then
        take that in account carefuly.  Rather than just looking up the
        type of parameters and return value, synthesize them too,
        especially when they are qualified types.  Bind the life time of
        the synthesized function type to the lifetime of the translation
        unit.
        * tests/data/test-abicompat/test7-fn-changed-report-1.txt: New
        test reference output.

        but in weak mode this time.

2015-07-20  Dodji Seketeli <dodji@redhat.com>

        Clean up the output of abicompat weak mode

2015-07-20  Dodji Seketeli <dodji@redhat.com>

        Fix computing the set of exported functions and varible symbols
        * src/abg-ir.cc (elf_symbol::get_name_and_version_from_id): Always
        set the version and name of the symbol.

        (corpus::exported_decls_builder::{keep_wrt_id_of_fns_to_keep,
        keep_wrt_id_of_vars_to_keep}): Reset the symbol name *and* version
        before passing it.  This is redundant with the fix in
        elf_symbol::get_name_and_version_from_id() that always set the
        symbol name and version now, but I felt it makes it easier to
        understand the fix overall.
        * tests/data/test-abicompat/libtest7-fn-changed-libapp-v{0,1}.so:

        * tools/abipkgdiff.cc (elf_file_paths): Make this global variable
        static.
        (extract_rpm): Rename parameter pkg_path name into package_path.

2015-07-15  Dodji Seketeli <dodji@redhat.com>

        Remove the last direct fiddling with ELF from abipkgdiff.cc
        * abg-dwarf-reader.h (enum elf_type): Move this declaration here
        from abipkgdiff.cc to here.
        (get_type_of_elf_file): Declare this new function.
        (get_soname_from_elf): Change this to take a path to the elf file
        rather than a Elf* handler.  So now to use this, the user doesn't
        have to get her hand dirty with elfutils.
        * src/abg-dwarf-reader.cc (get_soname_from_elf): Change this to
        take a path to the elf file rather than a Elf* handler.
        (elf_file_type): Move this static function here, from
        abipkgdiff.cc.
        (get_type_of_elf_file): New function.  This has been factorized
        out of create_maps_of_package_content() in abipkgdiff.cc.
        * tools/abipkgdiff.cc (class elf_file): Changed struct elf_file
        into this.  Make the default constructor private.
        (elf_file::elf_file): Change the constructor to just take the path
        to the elf_file.  The base name, soname and elf file type are now
        computed from the path file, in the constructor.  This makes
        instantiation much much easier from the point of view of the user
        of the type.
        (struct abi_diff): Renamed struct abi_changes into this.
        (abi_diff::has_changes): Define new member function.
        (abi_diffs): Remove this global variable.
        (package::package): Remove the elf file type from the set of
        parameters of this constructor.  Rather, compute that elf file
        type from the path to the elf file, in the constructor.  Again,
        this eases the use of the type.
        (elf_file_type): Remove this from here, as it got moved to
        abg-dwarf-reader.cc.
        (compare): In the elf_file overload, return true if the comparison
        yields ABI changes.
        (create_maps_of_package_content): Do not fiddle with elfutils
        stuff here.  Rather, just instantiate elf_file and the analyzing
        of the file magically happens.
        (compare): Make the package overload take an abi_diff as output
        parameter, rather than populating a global variable in return.
        (compare): Add an other overload for package that doesn't take the
        abi_diff as output parameter and write it in terms of the previous
        one.
        (main): Adjust as the instantiation of package is now simpler.

2015-07-08  Dodji Seketeli <dodji@redhat.com>

        Add a --verbose option to abipkgdiff
        * tools/abipkgdiff.cc (verbose): Add a new global variable.
        (package::erase_extraction_directory, extract_rpm, compare)
        (create_maps_of_package_content): Emit verbose information.
        (parse_command_line): Parse the --verbose option.

2015-07-08  Dodji Seketeli <dodji@redhat.com>

        Use the library to implement ABI comparison in abipkgdiff
        * tools/abipkgdiff.cc (compare): In the overload for elf_file, use
        abigail::comparison::compute_diff() to compare the ABI of two
        corpora.  The corpora themselves is read using
        abigail::dwarf_reader::read_corpus_from_elf().  This cleans up the
        output of the tool because nothing is emitted to standard output
        if the two ABI corpora compares equal.

2015-07-08  Dodji Seketeli <dodji@redhat.com>

        Fix several string passing issues in abipkgdiff.cc
        * tools/abipkgdiff.cc (elf_file::elf_file): Pass the strings by
        reference.  Also, change the order of the parameters; all the
        strings are passed first, then the elf_type is passed last.
        (package::package): Likewise, pass the strings by reference, not
        by value.
        (create_maps_of_package_content): Adjust for the change in
        parameters order of elf_file::elf_file.

2015-07-08  Dodji Seketeli <dodji@redhat.com>

        Only try to compare DSOs or executable binaries in abipkgdiff
        * tools/abipkgdiff.cc (compare): In the overload for packages,
        only compare binaries that are DSO or executable.

2015-07-08  Dodji Seketeli <dodji@redhat.com>

        Avoid flushing the output stream in abipkgdiff.cc
        * tools/abipkgdiff.cc (extract_package)
        (create_maps_of_package_content, compare, main): Avoid flushing
        the output stream arbitrarily.

2015-07-08  Sinny Kumari <sinny@redhat.com>

        Move get_soname() function to abg-dwarf-reader.h/cc
        * include/abg-dwarf-reader.h (get_soname_from_elf): Declare
        new function
        * src/abg-dwarf-reader.cc (get_soname_from_elf): Define new
        function
        * tools/abipkgdiff.cc (get_soname): Remove function
        (pkg_diff): Call get_soname_from_elf() instead of get_soname()

2015-07-07  Dodji Seketeli <dodji@redhat.com>

        Important organizational changes in abipkgdiff.cc
        * Avoid using shortened names when the line is not too long.
        * Use shared_ptr when possible.
        * When a function parameter is not meant to be nil, do not pass it
        as a pointer; rather, pass it as a reference.
        * Avoid doing things that can "fail" in a destructor; e.g, spawning
        a process.  Also, it's not common practise to cleanup a resource in a
        type destructor, when that resource has not been created in one of the
        member functions of the type.  It eases maintenance when resource
        creation and cleanup is performed at the same logical level.
        * tools/abipkgdiff.cc (option::package{1,2}): Rename
        option::pkg{1,2} into this, to increase legibility.
        (option::debug_package{1,2}): Likewise, rename
        option::debug_pkg{1,2} into this.
        (elf_file::~elf_file): Do not "delete this" in a destructor.  This
        leads to double free.  It's when someone invokes the "delete"
        operator on a pointer to the object that the destructor of the
        object is executed automatically; so if in the destructor the
        delete operator is called again, bad things are going to happen.
        As the destructor is now empty, remove it altogether.
        (elf_file_sptr): New typedef for shared_ptr<elf_file>.
        (package::path): Rename package::pkg_path into this, for better
        legibility.
        (package::extracted_package_dir_path): Rename
        package::extracted_pkg_dir_path into this.
        (package::type): Rename package::pkg_type into this.
        (package::is_debug_info): Rename package::is_debuginfo_pkg into
        this.
        (package::path_elf_file_sptr_map): Rename
        package::dir_elf_files_map into this because this is a map of
        path -> elf_file_sptr.  Also, now the value of the map element is
        a elf_file_sptr, no more an elf_file*.
        (package::debug_info_package): Rename package::debuginfo_pkg into
        this.
        (package::package): Adjust for the changes above.
        (package::{erase_extraction_directory,
        erase_extraction_directories}): New member functions.
        (elf_file_paths): Renamed dir_elf_files_path into this.
        (erase_created_temporary_directories)
        (create_maps_of_package_content)
        (extract_package_and_map_its_content, prepare_packages): New
        static functions.
        (get_soname, elf_file_type, extract_rpm): Make this static.
        (extract_package): Take a const package& rather than a
        package_sptr to express that the function really expects a non-nil
        object by reference (not by copy) and that the object won't be
        modified.  Using a reference removes the possibility that the
        pointer could be nil, causing crashes in the code where
        parameter->something was used.  Now only parameter.something can
        be used, so no crash possible there.  This is more solid code.
        (file_tree_walker_callback_fn): Rename callback() into this.  It
        makes the code more legible and kind of 'self-documented'.  At
        least you get the hint that this is a callback function for some
        file tree walking (ftw) function. Adjust for the relevant names
        renaming above.
        (compare): Rename compute_abidiff into this; again, this increases
        legibility; at least at the point of use of this function.  Rename
        compare_package() into a an overload of compare() as well.
        compare_package() used to take a vector of packages.  It was hard
        to guess by reading the signature of the function, which element
        of the vector is expected to be the first vector of the
        comparison, which one is to be the second, etc.  Now, this
        function takes two packages, named first_package and
        second_package.  That is more "typed"; that is, the signature is
        more meaningful.  Greater legibility, hopefully.  And in the body
        of the function, the debug information packages are now accessed
        using the package::debug_info_package data member.  Again, this is
        less surprising, I believe.  Also, explicitly erase the temporary
        files that were created during this comparison.  All this
        simplifies the logic of this function, hopefully.
        (parse_command_line): Make this static.  Add new --d1 and --d2
        command line switches that are shortcuts of --debug-info-pkg1 and
        --debug-info-pkg2.  Adjust this function for the relevant name
        changes above.  Make lines be shorter than 80 characters.
        (main): Do not create any vector of parameters anymore as the
        compare_packages() function don't take any vector of parameter
        anymore.  Just instantiate first_package and second_package now.
        Adjust for the relevant name changes above.  This hopefully
        simplifies the logic of this function.

        Wording fixes in abipkgdiff.cc
        * tools/abipkgdiff.cc (extract_package): Renamed extract_pkg into
        this because shortening 'package' into 'pkg' provides no
        legibility improvement.
        (compare_packages): Renamed pkg_diff() into this, so that the name
        of the function starts with a verb, and the shortened 'pkg' word
        is renamed back to the 'package' word.  This way, the code almost
        reads like normal English sentences with verbs and complement,
        thus enhancing legibility and easing latter maintenance.
        (main): Adjust for the changes above.

        Fix redundancy marking for change of types used directly
        * include/abg-comparison.h (pointer_map): Make this be a map of
        {size_t, size_t} pairs, rather than {size_t, bool}, so that each
        pointer in the map can be associated to another one.
        (diff_context::diff_has_been_visited): Return the pointer to the
        first diff node of the equivalence class that has been visited.
        * src/abg-comparison.cc (is_pointer_diff, is_reference_diff)

        (diff_context::mark_diff_as_visited): Save the pointer to the
        first diff node of a given class of equivalence that has been
        visited.
        (redundancy_marking_visitor::visit_begin): If a diff node is a
        child node of a function parameter diff or base diff node and if
        it's not a pointer or reference diff node, then do not mark it as
        redundant.  Also, make sure to not mark the first diff node of a
        given class of equivalence that has been visited, as redundant;
        only the other subsequent nodes should be marked redundant; we
        were hitting this case because of an optimization that makes
        equivalent class diff nodes to share their private (pimpl) data.

        Fix canonicalizing of member types ... *AGAIN*
        * src/abg-dwarf-reader.cc (build_ir_node_from_die): For typedefs,
        we don't need to test that the current scope is a class to know
        that we are looking at a member type.  Just looking at the
        is_member flag is enough.
        So the issue arises when for instance, we are reading a class that
        defines a member typedef (or enum) and uses that enum as the type of a
        data member.  When reading that data member (before reading the
        definition of the typedef), we read the type of the data member; so we
        hit the typedef.  But build_ir_node_from_die() cannot fully construct
        the scope of the typedef before handing off the typedef because we are
        currently building it!  So it hands out a non-complete version of the
        class that is being built;  'is_member' is not set to 'true' because
        we are getting the type of the data member; it's not *necessarily* a
        member type.  So we need to check !is_class_type(scope) to know if we
        are given a member type.  I am now thinking that the "is_member" flag
        is actually useless.  I think I'll remove it in a later patch.
        Anyway, this fixes 'abidiff libabigail.so libabigail.so' again.  I
        have some stashed patches that brings it's time down to ~ 45 seconds.
        So we are getting close to being able to include that *ultimate* test in
        regression test suite.  Oh well.
        * src/abg-dwarf-reader.cc (build_ir_node_from_die): When building
        typedefs, enum and memeber classes, check that the scope is a
        member class to detect if we are building a member type.  In which
        case the caller is going to handle the canonicalizing of the
        member type *after* it's access specification has been adjusted.
        Otherwise, that adjustments happens after the type has been
        canonicalized and bad things happen at comparison type.

        class_decl::member_function_template,

        of the ir_node_visitor methods.
        ({type_base, scope_type_decl, function_type,
        class_decl::base_spec}::traverse): New method.
        (type_base::get_canonical_type_for): Handle the case of the type
        already having a canonical type.  Properly hash the type using the
        dynamic type hasher.  Look through declaration-only classes to
        consider the definition of the class instead.  Fix logic to have a
        single pointer of return, to ease debugging.
        (canonicalize): Renamed enable_canonical_equality into this.
        (namespace_decl::get_pretty_representation): Define new method.

        the containing translation unit is not constructed yet, do not
        take virtual member functions in account when comparing the
        classes.  This is because when reading from DWARF, there can be
        DIEs that change the number of virtual member functions after the
        DIE of the class.  So one needs to start taking virtual members
        into account only after the translation unit has been constructed.

        (build_ir_node_from_die): Take a new flag that says if the ir node
        is a member type/function or not. Early-canonicalize base types.
        Canonicalize composite types that have only canonicalized
        sub-types.  Schedule the other types for late canonicalizing.  For
        class types, early canonicalize those that are non-member types,
        that are fully constructed and that have only canonicalized
        sub-types.  Adjust to the new signature of build_ir_node_from_die.

        signature of build_ir_node_from_die.
        (build_translation_unit_and_add_to_ir): Likewise.  Perform the
        late canonicalizing of the types that have been scheduled for
        that.
        (build_class_type_and_add_to_ir): Return a class_decl_sptr, not a
        decl_base_sptr.  Adjust for the new signature of
        build_ir_node_from_die.  Early canonicalize member types that are
        created and added to a given class, or schedule them for late
        canonicalizing.
        * src/abg-reader.cc (class read_context::{m_wip_classes_map,

        read_context::clear_types_to_canonicalize().
        (read_translation_unit_from_input): Call
        read_context::perform_late_type_canonicalizing() at the end of the
        function.
        (build_function_decl): Fix the function type canonicalizing (per
        translation) that was already in place.  Do the canonicalizing of
        these only when the type is fully built.  Oops.  This was really
        brokend.  Also, when the function type is constructed, consider it
        for type canonicalizing.
        (build_type_decl): Early canonicalize basic types.

        Handle the canonicalizing for these composite types: either early
        or late.
        (build_class_decl): Likewise.  Also, mark this class a 'being
        built' until it's fully built.  This helps the canonicalizing code
        to know that it should leave a class alone until it's fully built.
        * tests/test-ir-walker.cc (struct name_printing_visitor): Adjust
        to the visitor methods naming change.

        (finish_member_function_reading): Fix the comments of these
        functions.
        * src/abg-reader.cc (build_function_decl): Return a
        function_decl_sptr rather than a shared_ptr<function_decl>.
        (build_qualified_type_decl)
        (build_pointer_type_def, build_reference_type_def)
        (build_array_type_def, build_typedef_decl, build_class_decl): Use
        the is_<someking_of_type> functions here, rather than using the
        dynamic cast.  This increases maintainability.

        Share private data of class_diff nodes
        * src/abg-comparison.cc (class_diff::class_diff): Do not

        (compute_diff): In the overload for class_diff, initialize the
        private data of the new instance of class_diff to the private data
        of its canonical instance.
        (redundancy_marking_visitor::visit_begin): If a node is marked
        redundant, do not dare visit its children.  In cases of classes
        that have members that reference themselves, this prevents us from
        wrongly marking some of the data member changes as being
        redundant.

        declarations.
        * src/abg-ir.cc (equal): Do the same for the definitions of the
        overloads and adapt them to report about the kind of changes makes
        the two ABI artifact different -- only if the change_kind pointer
        is non-null.  That way, callers have a way to choose if they want

        the fact that priv_->subtype_changed_parms_ and

2014-10-28  Dodji Seketeli <dodji@redhat.com>

        Initial support for function suppressions
        * include/abg-comparison.h (enum visiting_kind): Change the
        meaning of this.  It was to determine if traversal was to be done
        in a pre or post manner.  But with the recent addition of
        diff_node_visitor::visit_{begin,end}() notifiers, the pre/post
        handling is taken care of in a different way.  So now the meaning
        of this enum is changed to handle whether diff node children
        should be visited or not.  So the enumerators are now
        DEFAULT_VISITING_KIND, and SKIP_CHILDREN_VISITING_KIND.  And it's
        a bit-field.
        (operator{&,~}): Declare more bit manipulation operators for the
        enum visiting_kind.
        (function_suppression_sptr, function_suppressions_type): New
        typedefs.
        (function_suppression, function_suppression::parameter_spec):
        Declare new types.
        (read_function_suppressions): Declare new function.
        (diff_node_visitor::diff_node_visitor): Adjust for the enum
        visiting_kind change.  Value-initialize the visiting_kind_ data
        member.
        * src/abg-comparison.cc (operator{&,~}): Define these operators
        for enum visiting_kind.
        (read_type_suppressions): Forward declare this static function.
        (read_function_suppression, read_parameter_spec_from_string):
        Define new static functions.
        (read_suppressions): Update to read function suppressions too,
        using the new read_function_suppression function above.
        (class function_suppression::parameter_spec::priv): Define new
        type.
        (function_suppression::parameter_spec::*): Define the member
        functions of the new function_suppression::parameter_spec type.
        (class function_suppression::priv): Define new type.
        (function_suppression::*): Define the member functions of the new
        function_suppression type.
        (diff::traverse): There is no more {PRE,POST}_VISITING_KIND
        enumerator.  So nuke the code that was dealing with it.
        (redundancy_marking_visitor::skip_children_nodes_): New data
        member flag.
        (redundancy_marking_visitor::visit_begin): If the current diff
        node is not be reported (is filtered out), do not bother visit its
        children nodes for the purpose of marking redundant nodes.  So use
        the new skip_children_nodes_ flag above to know we are in that case.
        (redundancy_marking_visitor::visit_end): Unset the new
        skip_children_nodes_ flag above when appropriate.
        * include/abg-fwd.h (is_function_decl): Declare new function.
        * include/abg-ir.h
        (function_type::get_parm_at_index_from_first_non_implicit_parm):
        Declare new member function.
        * src/abg-ir.cc (is_function_decl): Define new function.
        (function_type::get_parm_at_index_from_first_non_implicit_parm):
        Define new member function.
        * src/abg-comp-filter.cc (apply_filter): Adjust for the enum
        visiting_kind change.  No need to set it for filters anymore
        * doc/suppr-doc.txt: Update examples of function suppression.

        account when trying to detect that the first parameter of a member

        Avoid infinite loops in the comparison code for classes
        * src/abg-ir.cc (equals): In the overload for classes, make sure

        involved in the comparison.  Also, break at the first lhs virtual
        member function that is different from the rhs counter part.

        function type to registered with the translation unit.

        take a type.  This is because now, function types need to be

        * configure.ac: Support a new --enable-zip-archive option.  By
        default its value is set to the 'auto', meaning that if libzip is
        installed, that turns the option on -- just like if
        --enable-zip-archive was called with the value 'yes'; if libzip is
        not installed, that turns the option off -- just like if
        --enable-zip-archive was called with the value 'no'.  If libzip is
        detected, the pre-processor macro HAVE_LIBZIP is set to 1.  If
        --enable-zip-archive is turned on, the pre-processor macro
        WITH_ZIP_ARCHIVE is set to 1.
        * config.h.in (HAVE_LIBZIP, WITH_ZIP): New define.
        * src/abg-corpus.cc: Include config.h.  Guard the inclusion of
        abg-libzip-utils.h with the WITH_ZIP_ARCHIVE macro.  Likewise for
        the use of declarations coming from abg-libzip-utils.h.
        * src/abg-libzip-utils.cc: Include config.h.  Guard the file's
        content with the WITH_ZIP_ARCHIVE macro.
        * src/abg-reader.cc: Include config.h.  Guard the inclusion of
        abg-libzip-utils.h with the WITH_ZIP_ARCHIVE.  Likewise for the
        use of declarations coming from abg-libzip-utils.h.
        * src/abg-writer.cc: Likewise.
        * tests/Makefile.am: Build runtestwritereadarchive and runtestdot
        only if zip archives are supported.
        * tools/Makefile.am: The biar program is built only if
        zip archives are supported.
        * tools/bidiff.cc: Handle zip archives only if the
        WITH_ZIP_ARCHIVE macros is defined.
        * tools/bilint.cc: Likewise.

        to display help.
        (main): Tell --help, wrong options and missing argument apart and
        give an appropriate message on stderr.  The help string goes to
        stdout though.  Just like what GNU diff does.

2014-08-28  Dodji Seketeli <dodji@redhat.com>

        In bidiff, don't emit a report when the binaries have the same ABI
        * tools/bidiff.cc (main): For differences of zero length, do not
        emit any report.

        diff node is being traversed for the first time, mark it as being
        in the NOT_REDUNDANT_CATEGORY.  I don't know why I was doing this

        * src/abg-comparison.cc (class_diff::report): Put virtual member

        add/removal, then the rest (including data members changes).

        Consider symbol versions' public-ness during comparison
        * src/abg-ir.cc (elf_symbol::operator==): Rather than comparing
        bindings, compare public-ness here.  That is, if two symbol
        versions' differ because one is GLOBAL and the other one is WEAK,
        they should still be considered equal, from an ABI standpoint.

2014-08-27  Dodji Seketeli <dodji@redhat.com>

        Lookup proper names of symbol during determination of deleted/added decls
        * src/abg-comparison.cc
        ({class,corpus}_diff::ensure_lookup_tables_populated):  Now that in the

        (typedef read_context_sptr, create_read_context)
        (has_alt_debug_info): Declare these.
        (read_corpus_from_elf): Declare new overload.
        * src/abg-dwarf-reader.cc (find_alt_debug_info)
        (is_die_attribute_resolved_through_gnu_ref_alt)
        (build_primary_die_parent_relations_under)
        (build_alternate_die_parent_relations_under):
        Define new static functions.

        member functions.
        (read_context::load_debug_info): Painfully Get a handle on the
        alternate debug info section too.  We shouldn't have to do all
        this work; we could use the new dwarf_getalt() function from
        libdw, but we cannot as we want to support supports that predate
        that api.  When a version of elfutils gets released with that api
        though, we should conditionally use that instead.

        resolved DIE is from alternate debug info.  Also take a new
        parameter that tells if the input DIE is from alternate debug info
        sections.
        (build_die_parent_relations_under): Take the DIE -> parent map to
        act upon.  Also, add a new overload that takes a flag saying if
        the DIE is from alternate debug info or not, and act upon that.
        (build_die_parent_maps): Renamed build_die_parent_map into this
        and make it build DIE -> parent DIE relationship for the alternate
        debug info file as well.
        (find_last_import_unit_point_before_die, ): Adjust to use the
        information about if the relevant DIEs are in alternate debug info
        or not.

        decl map, that is per TU just as the primary DIE -> decl map.
        Adjust to use the information about if the relevant DIEs are in
        alternate debug info or not.
        (read_debug_info_into_corpus): Build the two DIE -> DIE parent
        maps (one for the primary debug info and one for the alternate
        debug info).

        points.
        (read_corpus_from_elf): New entry point overload that takes a
        read_context.

        show_base_name_alt_debug_info_path}): New data members.
        (display_usage): Update for the two new options
        --check-alternate-debug-info and
        check-alternate-debug-info-base-name.
        (parse_command_line): Parse the two options above.
        (main) Handle the two new options above.
        * tests/Makefile.am: Build the new runtestaltdwarf test.  Add the
        new data/test-alt-dwarf-file/* files to the build system.
        * tests/test-alt-dwarf-file.cc: New test driver.
        * tests/data/test-alt-dwarf-file/test0-common.cc: New test input
        files.

        Likewise.
        * tests/data/test-read-dwarf/test1.abi: Adjust. bidw doesn't emit
        an abstract constructor/destructor anymore. It emits just the
        functions matching the cdtor symbols found in the binary.
        * tests/data/test-read-dwarf/test2.so.abi: Likewise.

        (compute_diff): In the overload for corpus_sptr stick the corpora
        being compared, into the diff context.
        (class_diff::ensure_lookup_tables_populated): If a member function
        is allegedly removed, check that its underlying symbol is removed
        from the corpus as well.  Otherwise, consider that the member
        function hasn't been removed.  Likewise, if a member function is
        allegedly added, check that its underlying symbol has been added
        to the corpus as well.  Otherwise, consider that the member

        DW_AT_{specification,abstract_origin} attribute, do not add the

        scope.  It's in a scope because that built variable is for the DIE
        that is referred-to by the DW_AT_{specification,abstract_origin}
        attribute.  Likewise for member functions.  Also, now,
        get_scope_for_die can return a class for a function DIE because
        get_scope_for_die now returns the *logical* scope of the DIE; that
        is, it follows DW_AT_{specification,abstract_origin} attributes.

        Urgh.  So with this change, that function parameter is not dropped
        anymore.  I have seen that happening in a DWARF generated by GCC
        4.7.1 on libstdc++.so.  Hard to come up with a regression test
        case for this one.

        Really detect static-ness of data members.  Oops.
        * src/abg-dwarf-reader.cc (build_class_type_and_add_to_ir): Let's
        consider that a data member being not laid out (i.e, not having a
        data_member_location) is is a static data member.  Otherwise, we
        were not detecting static data members at all.  Well we were only
        inferring their presence from seeing the static variable
        definition later on.  That means we were missing most of the
        static variables.  Woops.
        * src/abg-comparison.cc
        (corpus_diff::priv::ensure_lookup_tables_populated): Now that we
        are really seeing static data members, let's be prepare to the
        fact that we can the same static data member being declared
        several times in a corpus.

        A virt mem fn deleted and added to the same offset is not harmful
        * src/abg-comp-filter.cc (has_virtual_mem_fn_change): A virtual
        member that gets deleted and added back again to the same vtable
        offset is not considered as being a virtual member function change
        suitable for VIRTUAL_MEMBER_CHANGE_CATEGORY.  Likewise for a
        function sub-type change not involving a change in the vtable
        offset.

2014-04-16  Dodji Seketeli <dodji@redhat.com>

        Work around "mangled name vanishing from one version of mem fn decl" bug
        * src/abg-comparison.cc
        (class_diff::ensure_lookup_tables_populated): If the first version
        of the member function decl doesn't have a mangled name while the
        second has it, try the lookups using the pretty representation of
        the function.

2014-04-16  Dodji Seketeli <dodji@redhat.com>

        Do not try to represent the offset for a static data member
        * src/abg-comparison.cc (represent_data_member(var_decl_sptr,
        ostream&)): If the data member is static, do not try to represent
        its offset.

2014-04-16  Dodji Seketeli <dodji@redhat.com>

        A static data member shouldn't be checked for having been laid out
        * src/abg-comparison.cc (represent_data_member(var_decl_sptr,
        ostream&)): If the data member is static do not check for it
        having been laid out.

2014-04-16  Dodji Seketeli <dodji@redhat.com>

        Provide a robust way of getting the size of a qualified type
        * include/abg-ir.h (qualified_type_def::get_size_in_bits): Declare
        new member function ...
        * src/abg-ir.cc (qualified_type_def::get_size_in_bits): ... and
        define it.  Keep in mind that some times the size of the
        underlying type can change between the moment the qualified type
        is created and the end of its life time.  That is because a
        subsequent DIE (from DWARF) can alter the size of the underlying
        type.  This overload allows the user to always query the size of
        the underlying type and keep the size of the qualified type in
        sync with it.

2014-04-16  Dodji Seketeli <dodji@redhat.com>

        Add an assert to the pointer diff reporting code

        should be reported as well.

        Little style adjustment in diff node categorization code
        * src/abg-comp-filter.cc (harmful_filter::visit): Factorize the
        categorization into SIZE_OR_OFFSET_CHANGE_CATEGORY for data member
        adding or removal and for data member type size change.

2014-04-15  Dodji Seketeli <dodji@redhat.com>

        If a diff node is in NO_CHANGE_CATEGORY do not report it anymore
        * src/abg-comparison.cc (diff::is_filtered_out): Now that we seem
        to be flagging every changes to a class into a category, we do not
        need to dive into reporting a diff not that is categorized as
        NO_CHANGE_CATEGORY anymore.  So let's have the implementation that
        one would expect for this function.

        When trying to recognize the global var_decl as being definition
        variables for static data members, lookup the declaration for the
        data member in the relevant class.  If found, then just flag the
        var_decl for the data member as being static; no need to add a
        var_decl as data member in that case, that would duplicate the
        data member.

        Make type_base::get_{size,alignment}_in_bits virtual

        this virtual.
        (typedef_decl::get_{size,alignment}_in_bits): Add new member
        functions.  Get the size,alignment from the underlying type and
        update the current size/alignment if they differ.  Keep in mind
        that the size of an underlying class_decl can change over its
        lifetime, given how the dwarf reader reads the type information,
        i.e, there can be a DIE for a class type with no size information
        that will lead to the creation of a class_decl with size zero.
        Later during the DWARF reading process, another DIE will
        supplement the type information, adding size information to that
        class_decl.  In between, a typedef_decl might have been created
        with the first version of the class_decl that has a zero size.  I
        guess this should be extended to the other type constructs that
        have an underlying type (qualified types, references and pointers).

        Report about functions of different names
        * src/abg-comparison.cc (function_decl_diff::report): Consider the
        case of functions with different names.  This doesn't happen in
        the current pipeline b/c they just show up as deleted/added
        functions so the function reporter doesn't see them as they have
        been already reported by now.

        (distinct_diff::entities_are_of_distinct_kinds): Consider two NULL
        decls are distinct types for the purpose of diffing.  This is just
        a shortcut to avoid creating a null_diff type for now.  But then,
        stop considering same pointers as different.  This was a bug.

        Insert reference, pointers and qual types at their declaration point
        * src/abg-dwarf-reader.cc (build_ir_node_from_die): Insert
        reference, pointers and qualified types at the point where we see
        them, in their scope, rather than under the scope of their
        underlying type.  This is because their might be first declared as
        member types and we don't want to loose that information.

2014-02-21  Dodji Seketeli <dodji@redhat.com>

        Avoid comparing member types and class templates
        * src/abg-comparison.h (compute_diff): For class_decl_sptr, do not
        compare member types and member class templates.  This adds a lots
        of noise that is not necessarily useful for now.
        * tests/data/test-bidiff/test-qual-type0-report.txt: Update tests.

        First approach to avoid duplication of IR nodes for forward-declared classes
        * src/abg-dwarf-reader.cc (is_declaration_only): Put this back (I
        removed it earlier).
        (build_class_type_and_add_to_ir): If the class is a
        declaration-only (a forward declaration), do not add a new
        declaration only IR node.

        Misc diff reporting output cleanup
        * src/abg-comparison.cc (function_decl_diff::report): Do not talk
        about changed function anymore.  Rather, say that some indirect
        sub-types changed in the function.

2014-02-19  Dodji Seketeli <dodji@redhat.com>

        Do not forget some member types/functions we built IR nodes for
        * src/abg-dwarf-reader.cc (build_class_type_and_add_to_ir):
        Associate the member type IR node to the offset of the die of the
        member type.
        (build_ir_node_from_die): For a DW_TAG_subprogram DIE that has a
        DW_AT_specification pointing to another subprogram DIE, associate

2014-02-19  Dodji Seketeli <dodji@redhat.com>

        Better support of static member variables
        * include/abg-fwd.h (fqn_to_components)
        (lookup_type_in_translation_unit, demangle_cplus_mangled_name):
        Declare new public entry points
        * src/abg-comparison.cc (corpus_diff::report): Report stuff about
        global variables using their mangled name, and demangle them.  If
        there is no mangled name for the variable, then use its pretty
        representation.
        (compute_diff): For the corpus overload, compare global variables
        using their mangled name, if its available; otherwise, fall back
        to using their pretty representation.
        * src/abg-corpus.cc (var_comp::operator()(const var_decl*,
        const_var_decl*)): Compare variables using their mangled name in
        priority.  If it's not available then use their pretty
        representation.
        * src/abg-dwarf-reader.cc
        (read_context::var_decls_to_re_add_to_tree): New accessor.
        (build_translation_unit_and_add_to_ir): If there is what appears
        to be a definition of a static member variable variable -- this is
        in case this definition lacks the DW_AT_specification attribute
        that links it to the DW_TAG_member or DW_TAG_variable DIE that is
        a child of the right class/structure DIE -- that is not at the
        right place in the DIE tree, remove it from the its current place
        in the tree and try to hang it off of the right DIE.  To do this,
        de-mangle its mangled name, look at what is supposed to be the
        parent class name, look it up in the translation unit IR, and if
        found, stick the variable IR node in there, as a static member
        variable.  If not found, then bad luck.
        (build_class_type_and_add_to_ir): Do not try to see if a member
        variable is static here as the way I was doing it was unreliable.
        Build the data member node directly w/o going through building a
        variable node first.  Register the data member in the die offset
        -> IR node map.
        (build_ir_node_from_die): When seeing DW_TAG_variable, look for a
        DW_AT_specification attribute.  If there is one, then it points to
        a the DIE of a data member and means that data member is static.
        Flag the IR node of that data member as static thus.  Update the
        die offset -> IR node map.  If there is no DW_AT_specification
        attribute or if it doesn't point to a data member DIE, schedule
        this variable tag for a stage when after the whole IR is built for
        the translation unit, the variable's mangled named is inspected,
        its hypothetical parent struct/class is looked up and the variable
        IR node is put into the node of the right struct/class IR node.
        * src/abg-ir.cc (enum lookup_entity_kind): New.
        (fqn_to_components, iterator, lookup_type_in_translation_unit)

        * src/abg-comparison.cc
        (class_diff::ensure_lookup_tables_populated): Support several
        instances of the same member function being deleted.  That can
        happen when the same member function was present in the initial
        class several times.  Yeah, I've seen that in dwarf.
        * src/abg-corpus.cc (corpus::priv::build_symbol_table): Do not add
        the same variable (identified by its mangled name) twice in the
        variable symbol table.

        * src/abg-reader.cc (read_context::m_decls_stack): Make this is a

        functions.
        (read_context::{get_cur_decl, push_decl, pop_decl}): Update this
        now that the decl stack uses a std::deque.
        (read_context::clear_decls_stack): New.
        (read_context::get_translation_unit):  Use the first decl of the
        decl stack, that is most certainly the global scope of the current

        sub-tree once, just to build an id->xml node map.  That way, when a

        its XML node, build the type from it and use it.  Do not forget to
        advance the xml reader cursor when the reading of the 'abi-instr'
        sub-tree is read.  Clear all the new maps we have used for the
        current translation unit.

        built is a member class, do not loose that information after it
        has been added to its scope.  Also, base types and types of member
        variables can be member types and should retain that information.
        (build_qualified_type): Likewise, the underlying type of a
        qualified type shouldn't loose the information about its
        potentially being a member type.

        Its ir_traversable_base::traversable() method takes an
        ir_node_visitor&.
        (ir_node_visitor::visit): Change these virtual overloads to take
        pointers to IR nodes, rather than references.  This will be useful
        to e.g, store these IR nodes in containers on the side for some
        algorithms to work.  That is going to be useful later to,
        e.g. build symbol tables on the side, using the visitor interface.

        * src/abg-ir.cc (*::traverse): Adjust comments and the call the

        Support reading member functions and member types from DWARF
        * include/abg-ir.h (method_type_sptr): New convenience typedef.
        * src/abg-dwarf-reader.cc (read_context::{dwarf_version,
        die_wip_classes_map}): New accessors.
        (die_is_virtual): Rename is_virtual into this.
        (is_type_tag, is_type_die, die_virtual_function_index): Define new

        During the creation of the class, arrange for
        build_ir_node_from_die on the current DIE to return a
        declaration-only class, representing the declaration for the class
        that is being constructed.  This breaks circular dependencies
        induced by decls/types that refer to the class being built, before
        the class is fully built and has a (logical) type ID.  Once the
        class is created, make it refer to the class declaration that was
        previously handed for the requests to the class DIE.  Now requests
        to the class DIE will just yield the newly built class.  Add
        support for member functions and member types.
        (build_corpus): Support reading the dwarf version and stick it
        into the context.
        (build_ir_node_from_die): Adjust for change in

        returning NULL type.

        (eval_last_constant_dwarf_sub_expr, die_member_offset)
        (build_class_type): New static functions.
        (build_ir_node_from_die<DW_TAG_{class, structure}_type>): Support
        creating IR node for class and struct by calling the new
        build_class_type.

        (decl_base::remove_member_decl): Likewise.
        (class_decl::{remove_member_decl, remove_member_type): Likewise.
        * src/abg-dwarf-reader.cc (die_decl_map_type): Change this map
        type so that the value is now a DIE offset, rather than a DIE.
        This is because many times the lifetime of DIEs is shorter than
        the one of the reader_context.  Also, the die offset uniquely
        designates a physical DIE even if several different instances of
        logical DIE might point to it.
        (struct die_hash): Remove this as it's useless now that we store
        DIE offsets in the map.
        (build_translation_unit): Call build_ir_node_from_die w/o setting
        the called_from_public_decl flag.  Prune the types that are not
        used by any public decls.
        (build_namespace_decl_and_add_to_ir): all build_ir_node_from_die
        w/o setting the called_from_public_decl flag.
        (build_ir_node_from_die): Change the only_public_decl flag into a
        called_from_public_decl flag.  Mark types used by public decls as
        such.  Adjust for the parm changes of build_qualified_type
        build_pointer_type_def, build_reference_type, and
        build_typedef_type.
        (build_qualified_type, build_pointer_type_def)
        (build_reference_type, build_typedef_type): Take a new
        called_from_public_decl.  Pass it to build_ir_node_from_die.
        (build_var_decl): Call build_ir_node_from_die with the
        called_from_public_decl flag set to true to flag the types
        referenced by this variable as being used.
        (build_function_decl): Take a called_from_public_decl flag as
        well, as this function can now call build_function_decl itself to
        build a function decl out of the value of the DW_AT_specification
        attribute, for DIEs representing function definitions.  Also, flag
        the types referenced by public functions are being used.
        * src/abg-ir.cc (translation_unit::priv::used_types_): New map for
        the used types.
        (translation_unit::{mark_type_as_used, prune_unused_types}):
        Define new methods.
        (scope_decl::remove_member_decl): Likewise.
        (remove_decl_from_scope): Define new function.
        (class_decl::{remove_member_decl, remove_member_type}): Define new
        methods.

        Support reading namespaces
        * include/abg-fwd.h (get_global_scope): Return a const
        global_scope.  Add a new overload that takes a naked pointer as
        parm.
        (insert_decl_into_scope, get_top_most_scope_under): Declare new
        entry points.
        * include/abg-ir.h (class decl_base, class scope_decl): Add
        insert_decl_into_scope as a friend of these classes.
        (scope_decl::{insert_decl_into_scope, find_iterator_for_member}):
        Declare new member.
        (scope_decl::get_member_decls): New non-const overload.
        * src/abg-dwarf-reader.cc (build_translation_unit): Remove the
        "recurse" parameter.  Adjust the call to build_ir_node_from_die to
        read just public decls that are at namespace scope.  Anything else
        should be dropped unless it's needed to emitting the public
        namespace-level decls.
        (build_namespace_decl_and_add_to_ir)
        (canonicalize_and_insert_type_into_ir): Define new static

        comments.
        (build_ir_node_from_die): Take a new "only_public_decl"
        parameter. For DW_TAG_base_type case, use the new
        canonicalize_and_insert_type_into_ir to insert the type at the
        right place in the global scope making sure it is seen before the
        current scope.  For pointer, references and qualified types, use
        canonicalize_and_insert_type_into_ir to add the type at the same
        scope as its underlying type.  Handle DW_TAG_{namespace,module}
        using the new build_namespace_decl_and_add_to_ir function.  Add
        some vertical spaces and some assertions.
        * src/abg-ir.cc (scope_decl::add_member_decl): Use scope_decl_sptr
        typedef.
        (scope_decl::{insert_member_decl,find_iterator_for_member}):
        Define new methods.
        (insert_decl_into_scope, get_top_most_scope_under): Define new
        functions.
        (get_global_scope): Constify the return type.
        (get_translation_unit): Adjust as get_global_scope now returns a
        const.
        * src/abg-reader.cc (get_translation_unit): Likewise.

2013-12-12  Dodji Seketeli <dodji@redhat.com>

        (scope_decl::add_member_decl): Use decl_base_sptr convenience
        typedef.
        (global_scope_sptr, namespace_decl_sptr): New convenience typedef.

        function.
        (canonicalize_and_add_type_to_ir): Do not crash on NULL input
        type.  Also, add a new overload for smart pointer on scope.
        (build_ir_node_from_die): For DW_TAG_base_type case, adjust as
        canonicalize_and_add_type_to_ir now takes smart pointers on
        scopes.  Support the DW_TAG_typedef case by calling the new
        build_typedef_type.

        (canonicalize_and_add_type_to_ir): Take a naked pointer to
        scope_decl rather than a smart pointer.
        (build_ir_node_from_die): For DW_TAG_base_type, adjust.  Support
        DW_TAG_pointer_type case.  For DW_TAG_{const,volatile}_type case,
        make sure the qualified type is in the same scope as its
        underlying type.
        * src/abg-ir.cc (get_global_scope, get_translation_unit): Define
        new overloads that acts on a naked decl_base.

        new canonicalize_and_add_type_to_ir which is a factorization of
        this code.  In the DW_TAG_{const,volatile}_type, use the new
        build_qualified_type and canonicalize_and_add_type_to_ir
        functions.

        location has empty file or empty line number.
        (build_translation_unit): Take a new address_size parameter.

        die_loc_and_name() here.
        (build_var_decl): Skip non-public vars.
        (build_corpus): Use dwarf_nextcu instead of dwfl_nextcu, so that
        we can get the address_size used in the current CU.  Note that for
        this we are getting the Dwarf* pointer from the context thanks to
        the new read_context::dwarf() getter.  Adjust the call to
        build_translation_unit to pass it the new address_size.
        (build_ir_node_from_die): Shorten lines a little bit.  Call the
        new build_function_decl to support reading DW_TAG_subprogram DIEs.

        and use its read_context::load_debug_info method to load the debug
        info.

        as representing base classes and member types changes is
        concerned.
        (type_decl_diff::report): Remove useless white space.

        member type has changed, as opposed to just saying that it has

        emitting useless vertical space and avoid saying that the class
        has "zero" insertion/deletion of a given kind of member.
        (scope_diff::report): avoid saying that the scope has "zero"
        insertion/deletion of a given kind of member.  Avoid useless

        (get_type_declaration): Define new function.
        (class_decl::add_member_decl): New method.
        (class_decl::add_member_type): Avoid silently added a new member
        type when that member type has already been (perhaps
        inadvertently) added to a scope already.  Rather, put a strict
        assert in place there.  Also add a new overload that constructs
        the member type out of a classic type and adds it to the class.
        (class_decl::{add_data_member, add_member_function}): Likewise.
        (class_decl::{add_member_function_template,
        add_member_class_template}): Avoid silently added a new member

        and functions, make sure /not/ to add the data, type of function to
        the current scope before adding it to the class_decl.  This was
        making the member not being added to the class because it already
        had a scope.
        (build_type_tparameter, build_type_composition)
        (build_non_type_tparameter, build_template_tparameter)

        class_decl::member_function::get_vtable_offset_in_bits into this.
        The offset is an index into a table; it's not a value in bits.
        * src/abg-hash.cc (class_decl::member_function::hash): Update wrt
        function name change above.
        * src/abg-ir.cc (class_decl::member_function::operator==):

        (method_type::set_class_type): I wonder what I was thinking when
        setting the first parameter's type to being the type of the
        class.  Remove this.
        (function_decl::get_pretty_representation): Use the "method "
        prefix for methods.  Avoid printing the first parameter of
        methods.  Use the qualified name of the parameter type, rather

        Fix erratic reporting of changed types & decls in scopes
        * src/abg-comparison.cc
        (scope_diff::ensure_lookup_tables_populated): A changed type/decl
        is not only one that has been both deleted and inserted (as is a
        type/decl with a given name N has been deleted and a type/decl
        with that same name N has been inserted), but we must also ensure
        that both inserted and deleted type/decl are not the same.
        Otherwise, it might has been a type/decl that has been shuffled
        around.

        Re-write middle snakes management in core diff algorithms
        * include/abg-diff-utils.h (point::set): New overload..
        (point::{add, operator<, operator>, operator<=, operator>=}): New
        methods.
        (point::operator!=): Constify.
        (point::operator==): Constify. Cleanup.
        (point::operator=): Keep emptiness.
        (class snake): New class definition
        (d_path_vec::{over_bounds, offset}): New methods.
        (d_path_vec::check_index_against_bound): Don't take a bound
        parameter anymore.  Use the new over_bound method above.  Fix up
        error reporting.
        (d_path_vec::d_path_vec): Fix d_path_vec size allocation.
        (d_path_vec::operator[]): Use the d_path_vec::at method to check
        all accesses against the bounds.  This is slower, but at least we
        can expect to have something that is more robust.  We can remove
        the bound checking later when we are sure the code has been tested
        enough.  Also use the new offset() method.
        (d_path_vec::at): Take long long.
        (ends_of_furthest_d_paths_overlap): Constify input parameters.
        (end_of_fr_d_path_in_k, end_of_frr_d_path_in_k_plus_delta): Take
        an instance of the new snake in parameter, rather than a bare end
        point that wasn't carrying enough information about the snake.
        Record the snake which consists of up to four points: a begin
        point, an intermediate point, a diagonal start point and an end
        point.  Return that snake upon successful completion.
        (compute_middle_snake): Take an instance of snake, rather than the
        two points that were supposed to represent a snake and with which
        we were loosing information before.  Revisit/simplify the logic of
        this function; this literally goes forward or in reverse, gets the
        resulting snake returned by the end_of_fr_d_path_in_k and
        end_of_frr_d_path_in_k_plus_delta functions, detect if these snakes
        overlap and just return the current snake.  Much simpler.  The
        caller now gets a snake, which has much more information than the
        previous snake approximation made of just two points.  Bonus
        point, this follows almost to the word, what the paper says.
        (maybe_record_match_point, find_snake_start_point): Remove these
        as there are not used by compute_middle_snake anymore.
        (print_snake, ses_len): Update these to take/handle a snake.
        (snake_end_points): New declaration.
        (compute_diff): When we are getting an empty first sequence, this
        means that we are inserting the second sequence *before* the
        beginning of the first sequence; keep this information by setting
        the insertion point index to -1, rather than zero.  Update this to
        get/handle snakes, rather than free points vaguely representing
        snakes.  Now that compute_middle_snake returns real snakes, handle
        the information we are getting.  Basically for edit scripts of
        length equal to 1, as the snake carries all the necessary
        information about the non-diagonal edge (as well as the diagonal
        edges), we (can) now precisely update the current edit script (as
        well as the longest common sub-sequence).  For edit scripts of
        length greater than 1, better at which points to divide the
        problem and consequently, at which points to conquer it back --
        better following The Paper to the letter.
        (display_edit_script): Update this for the use of instances of
        snake.
        * src/abg-diff-utils.cc (ends_of_furthest_d_paths_overlap): Update
        for constification of inputs.
        (snake_end_points): Define new function.
        (compute_middle_snake): Adapt for the taking an instance of snake.
        * tests/test-diff2.cc (main): Update for using instances of snake.
        * tests/test-core-diff.cc: Add new tests.
        * tests/data/test-core-diff/report0.txt: Update for output
        adaptation.

        compare_function_types function.
        (class_decl::operator==(const decl_base&)): Fix a thinko in the

        section comparison; that way, there won't be any chance to misuse
        the variables pertaining to a different section.  Fix the member

        Fix middle snake determination & ses len computation for d == 1
        * include/abg-diff-utils.h (compute_middle_snake): After the
        overlap determination happened, finding the middle snake can
        require keep on building the current path until the "end".  The
        end meaning reaching the max of D.  And that max is (M + N)/2 + 1.
        In the extreme cases were middle snake was on the very last step
        (M + N) + 1, we were not finding the middle snake.  Fix this.
        (compute_diff): When d == 1 and the first edge on the edit graph
        is a non-diagonal edge and when a_base != a_begin, we were failing
        to properly initialize x,y to find that non-diagonal edge.  Also
        we were failing to correctly compute the size of the sequence.
        Fix these.

        member_functions, member_function_templates,
        member_class_templates}): Make all these containers be vectors,
        rather than list.  This makes these containers (like
        class_decl::base_specs, class_decl::member_types, etc) be suitable
        to be used by the core diffing algorithms to diff their content.

2013-10-04  Dodji Seketeli <dodji@redhat.com>

        (class_decl_diff::data_members_changes): Rename
        class_decl_diff::data_member_changes into this.

        Fix middle snake determination
        * include/abg-diff-utils.h (point::{operator!=,operator==}): New
        operators.
        (end_of_fr_d_path_in_k, end_of_frr_d_path_in_k_plus_delta): Allow
        the initial point (-1,-1) that is not a point addressing elements
        of the input sequences, but that is the starting point of the
        forward paths and the ending point of reverse paths in the "Linear
        Refinement" of the algorithm.
        (is_match_point, maybe_record_match_point)
        (find_snake_start_point): New functions.
        (find_last_snake_in_path): Remove this.  It's not used anymore.
        (compute_middle_snake): Allow checking for overlapping paths even
        on points that are outside of the edit graph boundaries.  Once the
        overlap is detected, if a non-empty snake has been seen already,
        report it as the middle snake.  Otherwise, keep building the path
        until the end and report the last snake encountered as the middle
        snake.  Add comments.
        (compute_diff): For the d == 1 case, fix the logic of the finding
        the non-diagonal edge.  Fix typos.  Add comments.

        * tests/Makefile.am: Add this to the build system.

2013-10-02  Dodji Seketeli <dodji@redhat.com>

        Fix core diff algorithms for negative deltas
        * diff2.h (point::point): New copy constructor.
        (point::{operator+=, operator=}):  Use point::set.
        (point::{operator--, operator++,}): New operators.
        (d_path_vec::{a_size_, b_size_}): New members.
        (d_path_vec::max_d_): Remove this member.
        (d_path_vec::max_d): Compute this, now that max_d_ was removed.
        (point_is_valid_in_graph): Declare this new function.
        (end_of_fr_d_path_in_k, ): Return
        a bool when the end of furthest reaching past found is within the
        bounds of the edit graph.  Add comments.
        (end_of_frr_d_path_in_k_plus_delta): Likewise.  Also, delta can be
        negative; support that.  Do not cross the boundaries of the edit
        graph when following a diagonal edge.
        (find_last_snake_in_path): New function.
        (compute_middle_snake): Make forward/reverse d_path_vec be big
        enough to hold paths for M+N differences.  Normally M+N/2 should
        be enough, but we were getting weird out of bound errors.  Let's
        handle it this way for now.  Do not require that we check for
        overlap only when we are on a diagonal edge.  Once we detected an
        overlap, use the new find_last_snake_in_path to find the
        boundaries of the snake.
        (ses_len): Delta can be negative.
        (display_edit): Small minor English nit.

        (ensure_parent_dir_created): ... here in this new file.
        (dir_name, base_name): Define these.
        * tools/Makefile.am: New file.  Create a new libtoolsutils.la
        static library with stuff from tools/abg-tools-utils.cc in it.
        Also create a new 'biar' program with the stuff from the new
        tools/biar.cc in it.
        * tools/biar.cc: New file.  Contains the code for the new "biar"
        archive manipulation command line utility.
        * tests/test-read-write.cc (main): Adjust for the change about
        ensure_parent_dir_created above.
        * tests/test-write-read-archive.cc (main): Likewise.
        * Makefile.am (SUBDIRS): Add the new tools/ sub-directory to the
        build system.
        * configure.ac (AC_CONFIG_FILES): Generate tools/Makefile.
        * tests/Makefile.am: Make libtestutils.la link with the new
        libtoolsutils.la.  Make sure to express the dependencies between
        libtestutils.la and the binaries that depend on it.  Otherwise
        parallel builds can go awry.

        (define them ...
        * include/abg-ir.h
        (abigail::{translation_units,translation_unit_sptr): ... here.
        This is because a translation unit can be manipulated
        independently from an abi corpus.
        * src/abg-corpus.cc (corpus::get_translation_units): Adjust return
        type to comply with the change above.

2013-08-29  Dodji Seketeli <dodji@redhat.com>

        Fix header inclusion in abg-corpus.h
        * include/abg-corpus.h: Drop incomplete abg-traverse.h and
        abg-fwd.h.  Use abg-ir.h proper and be done with it.  Users of the
        library will just have to use abg-corpus.h to manipulate and the
        archives and the IR they contain.

2013-08-29  Dodji Seketeli <dodji@redhat.com>

        Add error message to translation_unit::write

        Rename abigail::corpus::{get_file_path --> get_path}
        * include/abg-corpus.h (corpus::{get_path, set_path): Renamed
        corpus::get_file_path and corpus::set_file_path into these as
        get_path/set_path is what is used elsewhere as well.
        * src/abg-corpus.cc (corpus::{get_path, set_path}): Likewise.
        * tests/test-write-read-archive.cc (main): Adjust for the change
        above.

2013-08-29  Dodji Seketeli <dodji@redhat.com>

        Initial writing/reading of an ABI corpus to an archive

        * src/abg-writer.cc: Inject the names from the std namespace into
        the abigail namespace, rather than into abigail::writer.
        (abigail::translation_unit::write): New overload.  This can now
        use ofstream and the other stuff from std that are injected in the
        abigail:: namespace.
        * tests/Makefile.am: Add tests/test-write-read-archive.cc to the
        build system; use that to build runtestwritereadarchive.  Also add
        the input test data from
        tests/data/test-write-read-archive/test[0-4].xml.

2013-08-27  Dodji Seketeli <dodji@redhat.com>

        Pass absolute paths to the compiler during the build
        * src/Makefile.am: Pass absolute file paths to the compiler during
        the build.  This helps in e.g in emacs' compilation mode, when the
        output shows an error reported by GCC's diagnostics, setting point
        to the error line and hitting 'enter' transports the user to the
        file location where the error happened; as the file path is nows
        absolute, emacs can always find it.  Otherwise, finding it depends
        on $PWD and whatnot.
        * tests/Makefile.am: Likewise.

2013-08-27  Dodji Seketeli <dodji@redhat.com>

        Misc cleanups in abg-fwd.h
        * include/abg-fwd.h: Move location, location_manager and
        translation_unit in the ir section.  Remove stuff that was
        commented out anyway.

2013-08-27  Dodji Seketeli <dodji@redhat.com>

        Move location, location_manager & translation_unit back into abg-ir.h
        * include/abg-corpus.h: Move location location_manager,
        translation_unit from here ...
        * include/abg-ir.h: ... to here.  The reason being that these are
        really constructs of the Internal Representation of the ABI/API of
        a translation unit.  What is left in abg-corpus is really
        exclusively related to an ABI Corpus, which I see more as a
        "packaging" construct that abstracts the bundling of several
        translation units together.  Also, I fixed some comments about the
        location/location_manger types; now a location is made specific to
        a translation unit; to an abi corpus.  A location of a given
        translation unit has to be decoded by the location manager of that
        same translation unit.

2013-08-22  Dodji Seketeli <dodji@redhat.com>

        Make libxml2 a private dependency wrt pkconfig

2013-08-19  Dodji Seketeli <dodji@redhat.com>

        Remove autotools-generated files
        * Makefile.in: Remove this autotools-generated file.  I know that
        people in the GCC-realm like storing these autotools-generated
        files into the source control system, but I believe in this day
        and age, this is annoying (to say the least) for the project
        developers for no good reason.  Requiring (the ubiquitous)
        autoconf for building from source is no big deal today, and typing
        "autoreconf" is not hard to do, really.  And it saves the
        developers for having to update a bunch of boilerplate
        automatically generated files into the source control system; this
        is really unnecessary noise and it is a commonly accepted good
        practice to avoid doing it these days.  To help people who do not
        know how to handle this, there is a COMPILING file in the source
        tree that explains how to build the project from sources.
        * aclocal.m4: Likewise.

        * test-read-write.cc (struct InOutSpec): New
        (main): Reorganize to give a list of input files to read and to
        write to an output file, have the test read the input files, write
        them, and diff the two.

        the corpus too.
