2016-03-30  Dodji Seketeli <dodji@redhat.com>

	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 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.
	(get_scope_for_die): If we couldn't get the parent of the DIE,
	then return a nil scope.

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.
	(write_context::record_type_as_referenced): Do not add the

	(write_context::sort_types): New sorting function.

	(write_member_type_opening_tag): Factorize out of ...
	(write_member_type): ... here.
	(write_class_decl_opening_tag): Factorize out of ...
	(write_class_decl): ... here.  Now, keep track also of
	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.

2015-09-07  Dodji Seketeli <dodji@redhat.com>

	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.
	* src/abg-reader.cc (read_corpus_from_input): Likewise.
	* src/abg-ir.cc (type_base::get_canonical_type_for): Once a type
	has been canonicalized, cache its hash value.
	* src/abg-hash.cc (type_base::dynamic_hash::operator()): If type
	canonicalization has been done and if the type has a cached value,
	use that one.

	(reference_diff::report): Describe lvalue/rvalue changes for
	references.
	* src/abg-ir.cc (reference_type_def::reference_type_def): Properly

	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

	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.

	(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.

	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.

	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

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.

	not do the real work here in the overload for decl_base Rather,

2015-08-14  Dodji Seketeli <dodji@redhat.com>

	Update comment about the supported formats in abipkgdiff
	* tools/abipkgdiff.cc: Now that .deb packages are supported, say
	it.

2015-08-14  Dodji Seketeli <dodji@redhat.com>

	Make the support of RPM and DEB package formats conditional
	* config.h.in: Define WITH_DEB and WITH_RPM pre-processor macros.
	* configure.ac: Add --enable-{rpm,deb} switches.  Check for
	rpm2cpio and cpio programs, unless --disable-rpm was provided.  If
	they are found and if --enable-rpm=auto was provided, then
	consider that --enable-rpm=yes was provided.  In that case, set
	the WITH_RPM macro to 1.  Otherwise, undefine that macro.
	Similarly, check for dpkg unless --disable-deb was provided.  If
	it's found and if --enable-deb=auto was provided, consider that
	--enable-deb=yes was provided.  In that case, set the WITH_DEB
	macro to 1.  Otherwise, undefine that macro.  Define the
	ENABLE_RPM and ENABLE_DEB conditional automake variables, if the
	rpm resp. deb support is enabled.  Emit a notice about the rpm and
	deb features being enabled or not, at the end of the configure
	process.
	* tests/test-diff-pkg.cc: Include the config.h header.
	(in_out_spec): Guard rpm tests by the WITH_RPM macro.  Similarly,
	guard deb tests by the WITH_DEB macro.
	* tools/abipkgdiff.cc: Include the config.h header.
	(extract_rpm): Guard this function definition with the WITH_RPM
	macro.
	(extract_deb): Guard this function definition with the WITH_DEB
	macro.
	(extract_package): Guard the handling of rpm packages with the
	WITH_RPM macro and the handling of deb package with the WITH_DEB
	macro.  If a package not-support package format is encountered,
	emit an appropriate error message and error 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

	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

	(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

	* tests/data/test-diff-suppr/test18-suppr-removed-var-report-5.txt: Likewise.

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,

	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.

	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

	package::extracted_dir_path_.
	(package::extracted_packages_parent_dir): New static member

	* include/abg-fwd.h
	(synthesize_type_from_translation_unit): Declare new function.
	(synthesize_function_type_from_translation_unit): Make the

	abigail::ir::translation_unit.
	(synthesize_function_type_from_translation_unit):

	data member.
	(synthesize_type_from_translation_unit): Define new function.
	(synthesize_function_type_from_translation_unit): Make the

	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.
	* tests/test-abicompat.cc (in_out_spec): Run the harness on the

	*  src/abg-corpus.cc
	(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:
	New test input binaries.
	* tests/data/test-abicompat/test7-fn-changed-app: Likewise.

	* 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.

2015-07-06  Dodji Seketeli <dodji@redhat.com>

	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.

2015-07-06  Dodji Seketeli <dodji@redhat.com>

	Fix missing newlines in diff report
	* src/abg-comparison.cc (class_diff::report): The overload of

	Fix redundancy marking for change of types used directly
	* include/abg-comparison.h (pointer_map): Make this be a map of

	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.
	* tests/data/test-diff-filter/test29-finer-redundancy-marking-v{0,1}.o:
	New test input binaries.

	Misc reporting fixes/improvements
	* src/abg-comparison.cc (distinct_diff::report): Remove spurious
	vertical space before reporting size and alignment changes here.
	(represent): In the variables/data member overload, report type
	changes first.  Then the other changes.

	changes too.  Also, make some small adjustments about how type
	size/alignment changes are introduced.

	supports size change reporting, just use that function rather than
	doing it here.

	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.

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):

	(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.

	Yet another fix to the DWARF method "static-ness" detection heuristic
	* include/abg-fwd.h (is_pointer, is_qualified_type): Declare new
	functions.
	* src/abg-ir.cc (is_pointer, is_qualified_type): Implement these
	new functions.
	* src/abg-dwarf-reader.cc (finish_member_function_reading):
	Sometimes, the this pointer of a non-static method can point to a
	*qualified* version of its containing type.  I am seeing that when
	comparing libstdc++.so from RHEL 6.5 and RHEL 7.  Take that in
	account when trying to detect that the first parameter of a member
	function is the this pointer, and thus detect that the function is
	a non static member function.

	Avoid infinite loops in the comparison code for classes

	comparison underway, do *not* unmark the current class as not being
	involved in the comparison.  Also, break at the first lhs virtual
	member function that is different from the rhs counter part.

	clone of a function that implements an interface (this happens for
	destructors, for instance).  In this case, really do the cloning

	to be member function, use finish_member_function_reading to read
	the properties relevant to its method-ness.

	Fix mangled name setting for static data members from DWARF

	properties to an existing var_decl.  For now just add mangled
	name.

2014-04-17  Dodji Seketeli <dodji@redhat.com>

	Fix class diff reporting issues for base classes
	* src/abg-comparison.cc (class_diff::report): For base classes,
	report their pretty representation.  Do not try to report a the
	diff of a changed base class that got filtered out.  Avoid
	emitting too many vertical white spaces.

2014-04-17  Dodji Seketeli <dodji@redhat.com>

	Simplify SIZE_OR_OFFSET_CHANGE_CATEGORY categorizing
	* src/abg-comp-filter.cc (harmful_filter::visit): Now that
	type_size_changed is correctly geared to not be fulled by
	decl-only classes, there is no need for its caller to handle that
	case.  And data_member_offset_changed ain't affected by decl-only
	classes anyway.  So the code is now much simpler.

2014-04-17  Dodji Seketeli <dodji@redhat.com>

2014-04-17  Dodji Seketeli <dodji@redhat.com>

	Don't blindly drop DIEs defined in the scope of a function
	* src/abg-dwarf-reader.cc (get_scope_for_die): Do not drop a DIE
	on the floor just because it is in the scope of a function.  We
	were dropping a function parameter because its type is a typedef
	defined right before the parameter, in the scope of the function.
	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.

2014-04-17  Dodji Seketeli <dodji@redhat.com>

	Useless code killing
	* src/abg-comparison.cc (decls_equal::operator()(const decls_type,

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

	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

	Fix dumping function to make them use generic ostream
	* src/abg-writer.cc (dump(const decl_base_sptr, std::ostream&)):
	Do not dump the content to cerr here.  Rather dump to the output

	(dump(const translation_unit&, std::ostream&)): Likewise.

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

	Misc style fixes
	* src/abg-ir.cc (get_translation_unit): Remove useless vertical

	(is_global_scope): Add missing API doc.

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

	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>

	Do not categorize size/offset changes when a decl-only class is involved
	* src/abg-comp-filter.cc (there_is_a_decl_only_class)

	(type_size_changed, data_member_added_or_removed)
	(has_virtual_mem_fn_change, has_non_virtual_mem_fn_change): Bail
	out if one of the types involved is a decl-only class.

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>

	Prefix pretty representation of static data members with 'static'
	* src/abg-ir.cc (var_decl::get_pretty_representation): Prefix
	pretty representation of static data members with 'static'.

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
	* src/abg-comparison.cc (pointer_diff::report): If the pointer
	diff node is deemed to be reported then the underlying diff node
	should be reported as well.

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

	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.

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

	Categorize changes to virt mem fncts as VIRTUAL_MEMBER_CHANGE_CATEGORY
	* src/abg-comp-filter.cc (has_virtual_mem_fn_change): New static

	* include/abg-ir.h (type_base::get_{size,alignment}_in_bits): Make
	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).

	* 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.

2014-02-28  Dodji Seketeli <dodji@redhat.com>

	Fix detection of entities of different kinds for diff purposes
	* src/abg-comparison.cc
	(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.

2014-02-28  Dodji Seketeli <dodji@redhat.com>

	* 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.

	Avoid comparing member types and class templates
	* src/abg-comparison.h (compute_diff): For class_decl_sptr, do not

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

	Do not forget some member types/functions we built IR nodes for

	Associate the member type IR node to the offset of the die of the
	member type.

	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)
	(lookup_node_in_translation_unit, lookup_type_in_translation_unit)

	(class_diff::ensure_lookup_tables_populated): Support several
	instances of the same member function being deleted.  That can

	has been added to its scope.  Also, base types and types of member

	(build_qualified_type): Likewise, the underlying type of a

	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.

	overloads over the top of the file.
	(build_namespace_decl_and_add_to_ir): Fix this by adding the
	namespace to the IR scope of the DIE (using the new

	* 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

	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

	w/o setting the called_from_public_decl flag.

	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.

	* 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
	functions.
	(build_corpus): Adjust ad build_translation_unit doesn't have the
	"recurse" parameter anymore.
	(canonicalize_and_add_type_to_ir): Make this static.  Fix
	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

	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

	* src/abg-reader.cc (get_translation_unit): Likewise.

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

	type.  Also, add a new overload for smart pointer on scope.
	(build_ir_node_from_die): For DW_TAG_base_type case, adjust as

	scopes.  Support the DW_TAG_typedef case by calling the new
	build_typedef_type.

	we can get the address_size used in the current CU.  Note that for

	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.

	as representing base classes and member types changes is
	concerned.

	Avoid missing member types while reading bi files
	* include/abg-fwd.h (get_type_declaration): Declare function.
	* include/abg-ir.h (class decl_base): Add class_decl as a friend.
	This to be able to call decl_base::set_scope from class_decl.
	(scope_decl::add_member_decl): Make this virtual protected, so
	that it can be called (virtually) from e.g, class_decl.
	(type_decl_sptr, typedef_decl_sptr): New convenience typedefs.

	(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

	* src/abg-reader.cc (push_decl_to_current_scope): Take a an extra
	flag saying if the current decl should be added to the current
	scope as well (in addition to being pushed onto the stack of

	(build_reference_type_def, build_enum_type_decl, build_typedef_decl)
	(build_function_tdecl, build_class_tdecl): Likewise.
	(build_class_decl): Likewise.  When building member data, types,
	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)
	(build_type): Adjust to add the template parm to the current scope

	const-ness.
	* src/abg-reader.cc (read_cdtor_const): Read the "const" xml

	Serialize vtable offset for virtual functions
	* include/abg-ir.h
	(class_decl::member_function::get_vtable_offset): Renamed
	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==):

2013-10-24  Dodji Seketeli <dodji@redhat.com>

2013-10-24  Dodji Seketeli <dodji@redhat.com>

	Fix string representation for variables and methods
	* src/abg-ir.cc (var_decl::get_pretty_representation): Don't use
	the pretty representation for the type of the variable; just use
	its qualified name.
	(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
	than its pretty representation.
	* src/abg-writer.cc (write_class_decl): Do not skip the first
	function parameter when serializing the method.

2013-10-24  Dodji Seketeli <dodji@redhat.com>

2013-10-24  Dodji Seketeli <dodji@redhat.com>

	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.

2013-10-24  Dodji Seketeli <dodji@redhat.com>

	Fix some class & scope diff reports formatting glitchs
	* src/abg-comparison.cc (class_diff::report): Quote data members.

2013-10-24  Dodji Seketeli <dodji@redhat.com>

	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.
	* tests/data/test-core-diff/report6.txt: Likewise.

	* include/abg-ir.h (type_shared_ptr_equal::operator()): Fix thinko
	in checking for the boolean value of the pointers to types.
	* src/abg-ir.cc (type_decl::operator==(const decl_base&)): Do not
	forget to compare the decl_base part of the type too.
	(type_decl::operator==(const type_base&)): To ease maintenance,
	re-use the equality operator that takes a decl_base.
	(scope_type_decl::operator==(const type_base&)): Likewise.
	(qualified_type_def::operator==(const type_base&)): Likewise.
	(compare_function_types): New sub-routine to compare function
	types.  It fixes an infinite recursion when comparing two methods
	of the same class.
	(function_type::operator==(const type_base&)): Use the new
	compare_function_types function.
	(class_decl::operator==(const decl_base&)): Fix a thinko in the
	first test of the function.  Use a dedicated scope for each class
	section comparison; that way, there won't be any chance to misuse
	the variables pertaining to a different section.  Fix the member
	function sections; we were mistakenly using the variables for the
	*data* section there.
	(class_decl::operator==(const type_base&)): Re-use the operator
	that takes a decl_base.
	(class_decl::operator==(const class_decl&)): Don't remove

	test now correctly considers two type template parameters at the
	same index as being equivalent.
	* tests/data/test-read-write/test13.xml: Likewise.

	decl_base&), type_base::operator==(const type_base),
	template_decl::operator==(const template_decl&) or

	* 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

	(class_decl::{base_specs, member_types, data_members,
	member_functions, member_function_templates,
	member_class_templates}): Make all these containers be vectors,

	(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

	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.

	$(top_builddir)/config.h file.

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
	* libabigail.pc.in: Libxml2 is not exposed to clients so make it

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.
	* configure: Likewise.
	* include/Makefile.in: Likewise.
