	Allow introductory text in commit log and ignore it when generating ChangeLog
	* gen-changelog.py (process_commit): Everything that comes between
	the subject line of the commit and the first \t* sequence is
	considered to be introductory text.  Ignore it when generating the
	ChangeLog entry.
	* COMMIT-LOG-GUIDELINES: Update the commit log guidelines to
	reflect the fact that we can now have introductory text in the
	commit log.

2014-11-18  Dodji Seketeli <dodji@redhat.com>

	Initial import of gen-changelog.py
	* gen-changelog.py: Copy from

	Sort functions by the their qualified name
	* src/abg-comparison.cc (function_comp::operator()): Sort the
	functions by only looking at their qualified name, as opposed to
	their return type name.

2014-11-08  Dodji Seketeli <dodji@redhat.com>

	Remove too tight assert from de-mangling code
	* src/abg-ir.cc (demangle_cplus_mangled_name):  The return length
	can be zero.  That means, no de-mangling was done.

2014-11-08  Dodji Seketeli <dodji@redhat.com>

	(corpus::{get_sorted_fun_symbols, get_sorted_var_symbols}): Define
	new member functions.
	* src/abg-writer.cc (write_elf_symbols_table): Take a sorted
	vector of symbols in parameters, rather than an unsorted map.
	(write_corpus_to_native_xml): Write a sorted vector of symbols,
	rather than an unsorted map of symbols.
	* tests/data/test-read-dwarf/test0.abi: Adjust.
	* tests/data/test-read-dwarf/test1.abi: Likewise.

2014-11-07  Dodji Seketeli <dodji@redhat.com>

	Fix template parameter hashing: make it know about enclosing template
	* include/abg-ir.h (template_parameter_sptr, template_decl_sptr)
	(template_decl_wptr): Declare new typedefs.
	(class template_decl): Make this virtually inherit decl_base and
	pimpl-ify it.
	(class template_parameter): Pimpl-ify this.  Make the constructor
	take the enclosing template parameter.
	(struct template_decl::hash): Declare this here, rather than in
	src/abg-hash.cc
	(class type_tparameter, non_type_tparameter, template_tparameter)
	(class type_composition, function_tdecl, class_tdecl): Pimpl-ify
	this.
	* src/abg-hash.cc (template_parameter::hash::operator()): Hash the
	enclosing template parameter.  Avoid infinite recursion due to the
	loop hash parameter -> hash template -> hash parameter.
	(template_decl::hash::operator()) Define this here, now that it's
	declared in abg-ir.h.  Also, avoid infinite recursion here; this
	is complementary to what is done in the hashing for
	template_parameter.
	({type_tparameter, template_tparameter, }::hash::operator()):
	Cache the calculated hash just as what is done for other types
	hashed.
	(template_decl::priv): Define this new type.
	(template_decl::{add_template_parameter, get_template_parameters,
	~template_decl}): Define these here to pimpl-ify template_decl.
	(template_parameter::priv): Define this new type.
	(template_parameter::template_parameter): Define this here to
	pimpl-ify template_parameter.  Note also that this now takes the
	enclosing template decl.
	(template_parameter::{get_index, get_enclosing_template_decl,
	get_hashing_has_started, set_hashing_has_started, operator::==}):
	Define these here to pimpl-ify template_parameter.
	(type_tparameter::priv): Define this new type.
	(type_tparameter::type_tparameter): Define this here to pimpl-ify
	type_tparameter.   Also, not that this constructor now takes the
	enclosing template decl.
	(class non_type_tparameter::priv): Define new type.
	(non_type_tparameter::{non_type_tparameter, get_type}): Define
	these here to pimpl-ify non_type_tparameter.  The constructor now
	takes the enclosing template.
	(template_tparameter::priv): Define new type.
	(template_tparameter::template_tparameter): Define this here to
	pimpl-ify template_tparameter.  This constructor now takes the
	enclosing template.
	(class type_composition::priv): New type.
	(type_composition::{type_composition, get_composed_type,
	set_composed_type}): Define these here to pimpl-ify
	type_composition.  The constructor now takes the enclosing
	template decl.
	(class function_tdecl::priv): Define new type.
	(function_tdecl::{function_tdecl, set_pattern, get_pattern,
	get_binding}): Define this here to pimpl-ify function_tdecl.
	(class class_tdecl::priv): Define this new type.
	(class_tdecl::class_tdecl): Define this here to pimpl-ify
	class_tdecl.
	(class_tdecl::set_pattern): Adjust to pimpl-ify.
	(class_tdecl::get_pattern): Define new pimpl-ified getter.
	* src/abg-reader.cc (build_function_tdecl, build_class_tdecl):
	Cleanup.  Pass the enclosing template to the template parameters
	that are built.
	(build_type_tparameter, build_type_composition)
	(build_non_type_tparameter, build_template_tparameter)
	(build_template_parameter): Take the enclosing template
	declaration and pass it to the template parameter being created.
	* tests/data/test-read-write/test12.xml: Fix and Adjust.
	* tests/data/test-read-write/test13.xml: Likewise.

2014-11-06  Dodji Seketeli <dodji@redhat.com>

	Style fix
	* include/abg-ir.h (class location): Remove useless white space.
	* src/abg-writer.cc (type_has_existing_id): Use type_base_sptr
	rather than shared_ptr<type_base>.
	(write_template_tparameter): Use template_tparameter_sptr rather
	than shared_ptr<template_tparameter>.

2014-11-05  Dodji Seketeli <dodji@redhat.com>

	Pass -std=gnu++11 to the compiler when --enable-cxx11 for tests
	* tests/Makefile.am: Pass -std=gnu++11 to the compiler when
	--enable-cxx11 has been used.

2014-11-05  Dodji Seketeli <dodji@redhat.com>

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.

	(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.

	Drop hardcoded substitutions
	* doc/Makefile.am: Do not use @docdir@.  It's indeed replaced at
	configure time. But there is no need for this limitation with
	automake, as $(docdir) is available and replaceable anytime.
	* src/Makefile.am: Likewise for @DEPS_LIBS@ and @DEPS_CFLAGS@.

	before the first release.
	* configure.ac (AM_INIT_AUTOMAKE): As the mandatory but empty
	files above are being removed for now, let's put in the 'foreign'
	mode of automake for the moment.  We'll likely remove it at
	release time.

2014-09-09  Jan Engelhardt <jengelh@inai.de>

	Set automake options globally

	a shared pointer initialized with the content of the weak pointer.
	(function_decl::function_decl, method_decl::method_decl): Remove

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

	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>

	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

	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.

	Work around "mangled name vanishing from one version of mem fn decl" bug

	Do not try to represent the offset for a static data member

	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.

	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

	one would expect for this function.

	* 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).

	* abg-comp-filter.cc (decl_name_changed): New static function.

	* src/abg-comparison.cc
	(function_decl_diff::ensure_lookup_tables_populated): Use the new
	function_decl::parameter::get_name_id() for the unique name of the
	parameter.  Also, fix a little logic error: if a parm is deleted

	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.

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

	Fix length calculation for type diffs.
	* src/abg-comparison.cc (diff_length_of_type_bases): Fix stupid

	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>

	Constify function_decl::parameter::get_type_pretty_representation()

	* 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.

2014-02-24  Dodji Seketeli <dodji@redhat.com>

	Fix documentation for the diff_utils namespace
	* include/abg-diff-utils.h (namespace diff_utils): Add comment.

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

	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).

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
	the offset of this DIE to the IR node of that other DIE.

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)
	(lookup_node_in_translation_unit, lookup_type_in_translation_unit)
	(demangle_cplus_mangled_name): New function definitions.

	Fixes needed to diff libstdc++ v4_4 against master
	* 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

	duplicated types, compare them by value.
	(build_class_decl): There can be duplicated class decls.
	* src/abg-writer.cc (write_enum_type_decl): The name of the enum
	needs to be xml-escaped.

	that is being constructed.  This breaks circular dependencies

	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.

	canonicalize_and_add_type_to_ir and build_class_type signature

	(canonicalize_and_insert_type_into_ir_under_scope): Move these
	overloads over the top of the file.
	(build_namespace_decl_and_add_to_ir): Fix this by adding the

	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

	well, as this function can now call build_function_decl itself to

	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.

	"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

	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}

	functions.
	(get_global_scope): Constify the return type.
	(get_translation_unit): Adjust as get_global_scope now returns a

	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.

	This was comparing just the decl_base and type_base part of the
	enum.  Now re-use the enum_type_decl::operator==(const decl_base)
	that compares the entirety of the types.

	Make it support introducing changed members as well as
	deletions/insertions.
	(class_diff::report): Adjust for the report_num_dels_or_ins ->
	report_mem_header change.  Use the new represent() overload to
	report about changed data members.  Adjust logic now that
	represent() emits a newline at its end.  Also adjust logic as far
	as representing base classes and member types changes is
	concerned.
	(type_decl_diff::report): Remove useless white space.

2013-11-20  Dodji Seketeli <dodji@redhat.com>

	ensure_lookup_tables_populated}): Define new methods.
	(class_diff::report): Detect and report when a base class or a
	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
	vertical spaces.

2013-11-19  Dodji Seketeli <dodji@redhat.com>

	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.
	(class_decl::add_member_decl): New virtual overload for
	scope_decl::add_member_decl.
	(class_decl::{add_member_type, add_data_member,
	add_member_function}): New overloads.
	* src/abg-ir.cc (add_decl_to_scope): Benign style cleanup.
	(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
	template when that template has already been (perhaps
	inadvertently) added to a scope already.  Rather, put a strict
	assert in place there.
	* 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
	scopes maintained in the reader context).
	(push_and_key_type_decl): Likewise, take that extra flag and pass
	it to push_decl_to_current_scope.
	(build_function_decl, build_var_decl, build_type_decl)
	(build_qualified_type_decl, build_pointer_type_def)
	(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
	explicitly, like previously.
	(handle_type_decl): Use build_type_decl function. Add the
	type_decl to the current scope, like previously.
	(handle_namespace_decl, handle_qualified_type_decl)

	* src/abg-ir.cc (class_decl::get_num_virtual_functions): New
	definition.
	(function_decl::get_pretty_representation): Represent
	destructors and const member functions.
	* src/abg-writer.cc (write_cdtor_const_static): Take a new bool
	parm for constness and serialize it.
	(write_class_decl): Serialize member functions & function template
	const-ness.
	* src/abg-reader.cc (read_cdtor_const): Read the "const" xml
	attribute, rather than "is_const".

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

	Fix num insertions reporting in member functions
	* src/abg-comparison.cc (class_diff::report): Fix num insertions
	reporting.

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

	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==):
	Likewise.
	* src/abg-reader.cc (build_class_decl): Rename the attribute
	vtable-offset-in-bits into vtable-offset.
	* src/abg-writer.cc (write_voffset): New function.
	(write_class_decl): Use the new write_voffset.  Cleanup.

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

	White space and style fixes
	* include/abg-ir.h (class_decl::member_function::member_function):
	Align function parameters.
	* src/abg-ir.cc (type_decl::operator==): Remove useless white spaces

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

	Do not report added/removed type_decls
	* src/abg-comparison.cc (scope_diff::report): Do not report
	added/removed type_decls.

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.
	(scope_diff::report): Simplify how we report changed types. Avoid
	unnecessary vertical spaces.

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

	Pretty representation for variables and types by default
	* include/abg-ir.h (var_decl::get_pretty_representation): New
	method declaration.
	* src/abg-ir.cc (decl_base::get_pretty_representation): Prefix
	types with the "type " string.
	(var_decl::get_pretty_representation): New method definition.

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.
	* tests/data/test-core-diff/report7.txt: Likewise.

	(find_snake_start_point): New functions.
	(find_last_snake_in_path): Remove this.  It's not used anymore.

	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

	parallel builds can go awry.

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

	Define translation_unit{_sptr,s} types in abigail::
	* include/abg-corpus.h (abigail::corpus::{translation_unit_sptr,
	translation_units):  Do not define these typedefs here.  Rather)
	(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.

	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.

	$(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>

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.
