Introduce the concept of environment
There are resources needed by the type system and other artifacts of
libabigail. Today, when the life time of those resources need to be
greater than all of artifacts of Abigail, then said resources are made
global.
But then global resources are not great, if anything because they
complicate the future use of the library in concurrent computing
setups.
As I was in the need to add one resource to be used by the type
system, I decided to sit down and first overhaul how these long lived
resources needed to be handled.
And here comes the concept of "environment". An environment is a
place where one can put resources that need to live longer than all
the other artifacts of the Abigail system. And so, the code that
creates Abigail artifacts needs and environment of for said artifacts
to use. In other words, artifacts now use an environment.
This has interesting and strong implications. We can only compare two
artifacts if they use the same environment. This is quite a strong
requirement.
But then when this requirement is fulfilled, comparing two types
amounts to just comparing two pointer values; hash values for types
can also be cached. Now *that* is great for speed of comparison, is
it not?
This patch introduce the concept environment (which is basically a new
abigail::ir::environment type), removes the global variables and uses
the environment instead. Each ABI artifact (either type or decl) now
has a ::get_environment() member function to get its environment.
This patch also disables the caching of hash values because the
caching must happen only *after* all types have been canonicalized.
We were not respecting that requirement until now, and that introduces
wrong hash values. A subsequent patch is going to re-introduce hash
value caching again, once the infrastructure is in place to set a flag
in the environment (hah!) once type canonicalization is done, and then
later read that flag when some client code requests a hash value, to
know if we should look in the hash value cache or not.
The patch obviously changes the output of numerous regression tests
(if anything b/c it disables hash value caching) so 'make check'
yields regressions. But then, it's only the subsequent patch that
updates the tests.

Use the ODR to speed up type canonicalization
This is the last patch of the series of 11 patches that started at the
patch with the subject:
constify is_class_type()
And below starts the cover letter of this patch.
While analyzing some libraries like libmozjs.so[1] it appeared that
type canonicalization takes a significant time to comparing composite
types that are re-defined in each translation units again and again.
The One Definition Rule[2] says that two types with the same name
shall designate the same thing; so when a type T being canonicalized
has the same name of a canonical type C in the same ABI corpus, then
this patch considers C as being the canonical type of T, without
comparing T and C structurally. This saves us from comparing T and C.
Before this patch, `abidw --noout libmozjs.so` was taking
approximatively 5 minutes; with the patch, it takes 1 minutes and 30
seconds.
To do this, the patch changes ABI artifacts to carry a pointer to the
corpus it belongs to. Whenever an ABI artifact is added to a given
context, the corpus of that context is propagated to the artifact;
that is now possible as the artifact now carries the property of the
corpus it belongs to.
During type canonicalization the ODR-based optimization outlined above
is performed as we can now compare the corpus of a given type again
the one of another type; it's now possible to know if two types come
from the same corpus.
There are a few cases though were the optimization is not performed:
- anonymous struct; when a struct is anonymous (it has no name, as
described in the DWARF), the DWARF reader gives it a name
nonetheless, so that diagnostics can refer to that anonymous type.
But then all anonymous types in the system have the same name. So
when faced with two anonymous types (with the same name) from the
same corpus, it's wrong to consider that they name the same thing.
The patch added an "is_anonymous" property to types created by the
DWARF reader so that such anonymous types can be detected by the
type canonicalizer; they are thus not involved in this
optimization. Note that the abixml writer and reader have been
updated to emit and read this property.
- typedefs. I have seen in some boost code two typedefs of the same
name refer to different underlying types. I believe this is a
violation of ODR. I'll need to investigate on this later. And I
think we really need to detect these ODR violations as part of
this enhancement request:
https://sourceware.org/bugzilla/show_bug.cgi?id=18941.
- pointers, references, arrays and function types, as they can refer
to the two exceptions above.
This is the last patch of the series which aimed at speeding up type
canonicalization in the context of types being re-defined a lot in
translation units.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.

Initial support for function suppressions
* include/abg-comparison.h (enum visiting_kind): Change the
meaning of this. It was to determine if traversal was to be done
in a pre or post manner. But with the recent addition of
diff_node_visitor::visit_{begin,end}() notifiers, the pre/post
handling is taken care of in a different way. So now the meaning
of this enum is changed to handle whether diff node children
should be visited or not. So the enumerators are now
DEFAULT_VISITING_KIND, and SKIP_CHILDREN_VISITING_KIND. And it's
a bit-field.
(operator{&,~}): Declare more bit manipulation operators for the
enum visiting_kind.
(function_suppression_sptr, function_suppressions_type): New
typedefs.
(function_suppression, function_suppression::parameter_spec):
Declare new types.
(read_function_suppressions): Declare new function.
(diff_node_visitor::diff_node_visitor): Adjust for the enum
visiting_kind change. Value-initialize the visiting_kind_ data
member.
* src/abg-comparison.cc (operator{&,~}): Define these operators
for enum visiting_kind.
(read_type_suppressions): Forward declare this static function.
(read_function_suppression, read_parameter_spec_from_string):
Define new static functions.
(read_suppressions): Update to read function suppressions too,
using the new read_function_suppression function above.
(class function_suppression::parameter_spec::priv): Define new

(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.

Do not compare access specs for member types & functions
It turns that in some DWARF (e.g, from the r300_dri.so binary in bug
libabigail/19024) the same class Foo can be declared as a struct, and
later defined as a class. Or the other way around.
In some cases, Foo can be declared as a struct, have a member type
Foo::Type with no access specifier, and later that member type is
still present with no access specifier when Foo is defined as a class.
So when comparing Foo::Type (from struct Foo) against Foo::Type (from
class Foo) we must not consider the access specification of Type,
otherwise, as in the first case it's 'public' and in the second case
it's 'private', the two member types would be considered different.
And something similar happens for member function declarations too.
This patch thus avoids comparing access specifiers for member types
and functions. Though it can be considered as a regression compared
to what was being done before, access specifiers don't have an impact
on ABI per se. And they can cause noise in the result, as we are
seeing here.
* include/abg-fwd.h (is_function_decl): Declare a new overload.
* src/abg-ir.cc (is_function_decl): Define a new overload.
(equals): In the overload for decl_base, do not compare access
specifiers when comparing member functions and types.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.

Use the ODR to speed up type canonicalization
This is the last patch of the series of 11 patches that started at the
patch with the subject:
constify is_class_type()
And below starts the cover letter of this patch.
While analyzing some libraries like libmozjs.so[1] it appeared that
type canonicalization takes a significant time to comparing composite
types that are re-defined in each translation units again and again.
The One Definition Rule[2] says that two types with the same name
shall designate the same thing; so when a type T being canonicalized
has the same name of a canonical type C in the same ABI corpus, then
this patch considers C as being the canonical type of T, without
comparing T and C structurally. This saves us from comparing T and C.
Before this patch, `abidw --noout libmozjs.so` was taking
approximatively 5 minutes; with the patch, it takes 1 minutes and 30
seconds.
To do this, the patch changes ABI artifacts to carry a pointer to the
corpus it belongs to. Whenever an ABI artifact is added to a given
context, the corpus of that context is propagated to the artifact;
that is now possible as the artifact now carries the property of the
corpus it belongs to.
During type canonicalization the ODR-based optimization outlined above
is performed as we can now compare the corpus of a given type again
the one of another type; it's now possible to know if two types come
from the same corpus.
There are a few cases though were the optimization is not performed:
- anonymous struct; when a struct is anonymous (it has no name, as
described in the DWARF), the DWARF reader gives it a name
nonetheless, so that diagnostics can refer to that anonymous type.
But then all anonymous types in the system have the same name. So
when faced with two anonymous types (with the same name) from the
same corpus, it's wrong to consider that they name the same thing.
The patch added an "is_anonymous" property to types created by the
DWARF reader so that such anonymous types can be detected by the
type canonicalizer; they are thus not involved in this
optimization. Note that the abixml writer and reader have been
updated to emit and read this property.
- typedefs. I have seen in some boost code two typedefs of the same
name refer to different underlying types. I believe this is a
violation of ODR. I'll need to investigate on this later. And I
think we really need to detect these ODR violations as part of
this enhancement request:
https://sourceware.org/bugzilla/show_bug.cgi?id=18941.
- pointers, references, arrays and function types, as they can refer
to the two exceptions above.
This is the last patch of the series which aimed at speeding up type
canonicalization in the context of types being re-defined a lot in
translation units.

Make type_has_non_canonicalized_subtype() tighter
type_has_non_canonicalized_subtype() gives up too quickly.
For instance, suppose it's looking a type 'foo'. If foo has no
canonicalized type yet and has a data member which type is foo* (for
instance), then type_has_non_canonicalized_subtype() just sees that
type 'foo*' has no canonicalized type, and so it returns, saying that
he found a non-canonicalized subtype for foo.
In that case though, what type_has_non_canonicalized_subtype() should
do is detect that foo* is a pointer to foo itself, so it shouldn't
count as a non-canonicalized sub-type. It should keep going and look
for other meaningful non-canonicalized sub-types.
And this what this patch does. It changes the sub-type walker that
type_has_non_canonicalized_subtype() uses, so that
- it doesn't flag sub-types that refer to the type we are looking
at as non-canonicalized sub-types. This is for sub-types that
are combinations of pointers, references and typedefs.
- it doesn't consider sub-types of member functions of the type we
are looking at, unless that member function is virtual.
The result is that more types are canonicalized early during DWARF
reading, and so there are less types to store on the side for late
canonicalization. This can have a big impact on, e.g, C++ libraries
with tens of thousands of types.

When reading DWARF set member type access where the type is built
The DWARF reader assumes that the DIEs for all member types are seen
by build_class_type_and_add_to_ir(), as member type DIEs of the DIE of
the class. Well that assumption is not correct because there can be
errors in the DWARF we are looking at. One of these errors I stumbled
accross is that a DIE for a typedef that should be a member typedef is
actually a child of a *function* DIE. And that function DIE is a
child of the class. Go figure. In any case, get_scope_for_die()
already fixes that up and behaves as if the DIE of the typedef is a
child of the DIE of the class. A side effect of this is that when
build_class_type_and_add_to_ir() reads the DIE of the class, it never
sees the DIE for that typedef.
The takeaway of this state of affairs is that we cannot rely on
build_class_type_and_add_to_ir() to update the member access specifier
for member types because it does not see all member types. Rather
build_ir_node_from_die() detects (reliably) that the type is a member
type and updates the access specifier there.
I also realize that the "is_member_type" flag of
build_ir_node_from_die() and friends is useless now because inside
build_ir_node_from_die() to know that that the type we are building is
a member type, we just need to look at the scope and see if it's a
class type.
So by doing all this, this patch fixes the fact that some types were
not being canonicalized because build_class_type_and_add_to_ir() was
not seeing them. Ahhhh, DWARF.
* include/abg-fwd.h (is_class(decl_base*)): Return a class_decl*
rather than just a bool.
* abg-ir.cc (is_class(decl_base*)): Return a class_decl* rather
than just a bool. Simplify the implementation.
* src/abg-dwarf-reader.cc
(maybe_set_member_type_access_specifier): Define new static
function.
(build_ir_node_from_die): Remove the is_member_type flag. When
building member types set their access specifier. Simplify the
logic of detecting that a type is a member type; basically
delegate taht to the new maybe_set_member_type_access_specifier().
(build_class_type_and_add_to_ir): Do not try to set the member
type access specifiers anymore.
(build_qualified_type, build_pointer_type, build_reference_type)
(build_typedef_type, build_var_decl, build_function_decl): Adjust.

Canonicalize types either early or late after TU reading
While trying to diff two identical files (abidiff foo.so foo.so) it
appeared that canonicalizing types during e.g, the DWARF reading
process was leading to subtle errors because it's extremely hard to
know when a type is complete. That is, during the building of a class
type C, a pointer to C can be built before C is complete. Worse, even
after reading the DIE (from DWARF) of class C, there can be DIE seen
later in the translation unit that modifies type C. In these late
cases, one needs to wait -- not only until C is fully built, but also
sometimes, after the translation unit is fully built -- to
canonicalize C and then the pointer to C. This kind of things.
So now there are two possible points in time when canonicalization of
a type can happen. It can happen early, when the type is built. This
is the case for basic types and composite types for which all
sub-types are canonicalized already. It can happen late, right after
we've finished reading the debug info for the current translation
unit.
So this patch fixes the IR traversal and uses that to walk the
translation unit (or even types) after it's built. It does away with
the first attempt to perform early canonicalizing only.
The patch also handles type canonicalizing while reading xml-abi
format.
* include/abg-fwd.h (is_class_type)
(type_has_non_canonicalized_subtype): Declare new functions.
(is_member_type): Remove the overload that takes a decl_base_sptr.
It's superfluous. We just need the one that takes a
type_base_sptr.
* include/abg-ir.h (translation_unit::{is_constructed,
set_is_constructed}): Add new methods.
(class_decl::has_virtual_member_functions): Likewise.
(class decl_base): Makes it virtually inherit ir_traversable_base.
(class type_base): Make this virtually inherit traversable_base
too.
(type_base::canonicalize): Renamed enable_canonical_equality
into this.
(type_base::traverse): Declare new virtual method.
(canonicalize): Renamed enable_canonical_equality into this.
(scope_type_decl::traverse): Declare new virtual method.
(namespace_decl::get_pretty_representation): Declare new virtual
method.
(function_type::traverse): Likewise.
(class_decl::base_spec::traverse): Likewise.
(ir_node_visitor::visit): Remove the overloads and replace each of
them with a pair of ...
(ir_node_visitor::{visit_begin, visit_end}): ... of these.
* include/abg-traverse.h (traversable_base::visiting): New
method.
(traversable_base::visiting_): New data member.
(traversable_base::traversable_base): New constructor.
* src/abg-ir.cc ({scope_decl, type_decl, namespace_decl,
qualified_type_def, pointer_type_def, reference_type_def,
array_type_def, enum_type_decl, typedef_decl, var_decl,
function_decl, function_decl::parameter, class_decl,
class_decl::member_function_template,
class_decl::member_class_template, function_tdecl,
class_tdecl}::traverse): Fix this to properly set the
traversable_base::visiting_ flag and to reflect the new signatures
of the ir_node_visitor methods.
({type_base, scope_type_decl, function_type,
class_decl::base_spec}::traverse): New method.
(type_base::get_canonical_type_for): Handle the case of the type
already having a canonical type. Properly hash the type using the
dynamic type hasher. Look through declaration-only classes to
consider the definition of the class instead. Fix logic to have a
single pointer of return, to ease debugging.
(canonicalize): Renamed enable_canonical_equality into this.
(namespace_decl::get_pretty_representation): Define new method.
(ir_node_visitor::visit): Replace each of these overloads with a
pair of visit_begin/visit_end ones.
(translation_unit::priv::is_constructed_): New data member.
(translation_unit::priv::priv): Initialize it.

(is_class_type(decl_base *d)): Define new function.
(class_decl::has_virtual_member_functions): Define new method.
(equals(const class_decl&, const class_decl&, change_kind*)): If
the containing translation unit is not constructed yet, do not
take virtual member functions in account when comparing the
classes. This is because when reading from DWARF, there can be
DIEs that change the number of virtual member functions after the
DIE of the class. So one needs to start taking virtual members
into account only after the translation unit has been constructed.
(class non_canonicalized_subtype_detector): Define new type.
(type_has_non_canonicalized_subtype): Define new function.
* src/abg-corpus.cc (symtab_build_visitor_type::visit): Renamed

Canonicalize composite types that have only canonicalized
sub-types. Schedule the other types for late canonicalizing. For
class types, early canonicalize those that are non-member types,

(build_translation_unit_and_add_to_ir): Likewise. Perform the

that.
(build_class_type_and_add_to_ir): Return a class_decl_sptr, not a
decl_base_sptr. Adjust for the new signature of
build_ir_node_from_die. Early canonicalize member types that are

canonicalizing.
* src/abg-reader.cc (class read_context::{m_wip_classes_map,
m_types_to_canonicalize}): New data members.
(read_context::{clear_types_to_canonicalize,
clear_wip_classes_map, mark_class_as_wip, unmark_class_as_wip,

read_context::clear_types_to_canonicalize().
(read_translation_unit_from_input): Call
read_context::perform_late_type_canonicalizing() at the end of the
function.
(build_function_decl): Fix the function type canonicalizing (per
translation) that was already in place. Do the canonicalizing of
these only when the type is fully built. Oops. This was really
brokend. Also, when the function type is constructed, consider it
for type canonicalizing.
(build_type_decl): Early canonicalize basic types.
(build_qualified_type_decl, build_pointer_type_def)
(build_pointer_type_def, build_reference_type_def)
(build_array_type_def, build_enum_type_decl, build_typedef_decl):
Handle the canonicalizing for these composite types: either early
or late.
(build_class_decl): Likewise. Also, mark this class a 'being
built' until it's fully built. This helps the canonicalizing code
to know that it should leave a class alone until it's fully built.
* tests/test-ir-walker.cc (struct name_printing_visitor): Adjust
to the visitor methods naming change.
* configure.ac: Generate the tests/runtestcanonicalizetypes.sh
testing script from tests/runtestcanonicalizetypes.sh.in.
* tests/runtestcanonicalizetypes.sh.in: Add the template for the
new runtestcanonicalizetypes.sh script that test for type
canonicalizing.
* tests/Makefile.am: Add the new runtestcanonicalizetypes.sh
regression testing script to the build system.

Make type_has_non_canonicalized_subtype() tighter
type_has_non_canonicalized_subtype() gives up too quickly.
For instance, suppose it's looking a type 'foo'. If foo has no
canonicalized type yet and has a data member which type is foo* (for
instance), then type_has_non_canonicalized_subtype() just sees that
type 'foo*' has no canonicalized type, and so it returns, saying that
he found a non-canonicalized subtype for foo.
In that case though, what type_has_non_canonicalized_subtype() should
do is detect that foo* is a pointer to foo itself, so it shouldn't
count as a non-canonicalized sub-type. It should keep going and look
for other meaningful non-canonicalized sub-types.
And this what this patch does. It changes the sub-type walker that
type_has_non_canonicalized_subtype() uses, so that
- it doesn't flag sub-types that refer to the type we are looking
at as non-canonicalized sub-types. This is for sub-types that
are combinations of pointers, references and typedefs.
- it doesn't consider sub-types of member functions of the type we
are looking at, unless that member function is virtual.
The result is that more types are canonicalized early during DWARF
reading, and so there are less types to store on the side for late
canonicalization. This can have a big impact on, e.g, C++ libraries
with tens of thousands of types.

Make determining of compatible types complete
Until now, two types that are different were considered compatible if
one type is a typedef of the other. This is useful because two
different types, if compatible, are not ABI-incompatible. This patch
extends the concept of compatible types to types which might have
sub-types that are typedefs of each others, including function types.
Note implementing this required that I fixed various other things left
and right. Like style fixes, crash avoiding fixes, etc.
* include/abg-fwd.h (is_reference_type, is_function_type)
(is_method_type): Declare new predicates.
* include/abg-ir.h (class qualified_type_def): Pimpl this class.
(qualified_type_def::qualified_type_def): Use the convenience

qualified_type_def::CV type rather than char.
(qualified_type_def::get_underlying_type): Use the convenience
type_base_sptr typedef.
(pointer_type_def::pointer_type_def): Likewise.
(function_decl::parameter::parameter): Add a new constructor.
* src/abg-ir.cc (is_reference_type, is_function_type)
(is_method_type): Define new predicates.
(class qualified_type_def::priv): Define this new private type,
for the purpose of Pimpl-ifying the qualified_type_def class.
(qualified_type_def::{qualified_type_def, build_name,
get_cv_quals_string_prefix, get_underlying_type}): Adjust for the
purpose of Pimpl-ifying the qualified_type_def class.
(equals): In the qualified_type_def, reference_type_def overloads,
trust the fact that we have operator== overload for the
type_base_sptr. This avoids crashes for when the (possible)
underlying type is null.
(pointer_type_def::operator==): Likewise.
(strip_typedef): Make this recursively strip
typedefs from sub-types.
(types_are_compatible): Handle null types.
(qualified_type_def::{get_cv_quals, set_cv_quals}): Handle
qualified_type_def::CV rather than char.
(pointer_type_def::pointer_type_def): Use the convenience
type_base_sptr typedef.
* include/abg-comparison.h (distinct_diff::compatible_child_diff):
Declare new member function.
* src/abg-comparison.cc (distinct_diff::compatible_child_diff):
Define new member function.
(distinct_diff::chain_into_hierarchy):
Chain the compatible child diff node that might be present.
(distinct_diff::report): Now when a distinct diff carries a
compatible change, mention it in the report.
* src/abg-comp-filter.cc (is_compatible_change): A compatible
change can now involve types that are not typedefs. Only their
sub-types need to be involved with typedef-ness.
* tests/data/test-diff-dwarf/test{2,4,5}-report.txt: Adjust.

Make determining of compatible types complete
Until now, two types that are different were considered compatible if
one type is a typedef of the other. This is useful because two
different types, if compatible, are not ABI-incompatible. This patch
extends the concept of compatible types to types which might have
sub-types that are typedefs of each others, including function types.
Note implementing this required that I fixed various other things left
and right. Like style fixes, crash avoiding fixes, etc.

(is_method_type): Declare new predicates.
* include/abg-ir.h (class qualified_type_def): Pimpl this class.

type_base_sptr typedef.

purpose of Pimpl-ifying the qualified_type_def class.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.

Bug 19025 - abixml writer forgets to emit some member types
When a member type (a type that is a member of a class) M is
referenced by some types emitted by abixml, but the context of M (the
class type which M is a member of) is not itself referenced by any ABI
artifact, then abixml forgets to emit the context of M and thus M
itself.
With this patch, when the abixml writer has emitted almost all ABI
artifacts for the current translation unit, it looks for types that
have been referenced by the emitted ABI artifacts, but that haven't
been emitted themselves.
It then emits those referenced-but-not-emitted types, and makes sure
their contexts are emitted as well.

the one of the reader_context. Also, the die offset uniquely
designates a physical DIE even if several different instances of
logical DIE might point to it.

used by any public decls.

such. Adjust for the parm changes of build_qualified_type
build_pointer_type_def, build_reference_type, and

called_from_public_decl flag set to true to flag the types
referenced by this variable as being used.
(build_function_decl): Take a called_from_public_decl flag as
well, as this function can now call build_function_decl itself to
build a function decl out of the value of the DW_AT_specification
attribute, for DIEs representing function definitions. Also, flag
the types referenced by public functions are being used.

Make decl_base::get_context_rel() return a naked pointer
Accessing the context relationship of declarations and setting some
member properties appear to be high in performance profiles due to
shared pointer handling. This patch makes the context relationship

the case of a DIE that has both DW_AT_specification and
DW_AT_abstract_origin set. That is, DW_AT_abstract_origin is set,
and the origin has DW_AT_specification set. This is basically a
clone of a function that implements an interface (this happens for
destructors, for instance). In this case, really do the cloning

Make decl_base::get_context_rel() return a naked pointer
Accessing the context relationship of declarations and setting some
member properties appear to be high in performance profiles due to
shared pointer handling. This patch makes the context relationship
accessors return a naked pointer and also passes a bunch of shared
pointer as references around.

takes the member as a reference to a smart pointer.
(set_member_function_{is_dtor, is_ctor, is_const, vtable_offset,
is_virtual}): Pass the member function as a reference.
(set_member_function_is_const, set_member_function_is_virtual):
Pass the member function as a non-const reference.
* include/abg-ir.h (decl_base::get_context_rel): Return a naked
pointer.
(set_member_is_static, set_member_function_is_virtual): Adjust
this friend declaration.
(set_member_access_specifier): Add an overload that takes a
reference to the member. Pass a reference to smart pointer to the
other overload.
(set_member_function_is_{is_ctor,is_dtor,is_const,is_virtual,vtable_offset}):
Take a non-const reference to function_decl.
* src/abg-ir.cc (decl_base::get_context_rel): Likewise.
(equals(const decl_base&, const decl_base&, change_kind*)):
Adjust.

Make decl_base::get_context_rel() return a naked pointer
Accessing the context relationship of declarations and setting some
member properties appear to be high in performance profiles due to
shared pointer handling. This patch makes the context relationship
accessors return a naked pointer and also passes a bunch of shared
pointer as references around.
* include/abg-fwd.h (set_member_is_static): Add an overload that
takes the member as a reference to a smart pointer.
(set_member_function_{is_dtor, is_ctor, is_const, vtable_offset,
is_virtual}): Pass the member function as a reference.
(set_member_function_is_const, set_member_function_is_virtual):
Pass the member function as a non-const reference.
* include/abg-ir.h (decl_base::get_context_rel): Return a naked
pointer.
(set_member_is_static, set_member_function_is_virtual): Adjust
this friend declaration.
(set_member_access_specifier): Add an overload that takes a
reference to the member. Pass a reference to smart pointer to the
other overload.
(set_member_function_is_{is_ctor,is_dtor,is_const,is_virtual,vtable_offset}):
Take a non-const reference to function_decl.
* src/abg-ir.cc (decl_base::get_context_rel): Likewise.
(equals(const decl_base&, const decl_base&, change_kind*)):
Adjust.
(equals(const var_decl&, const var_decl&, change_kind*)):
Likewise.
(get_member_access_specifier, get_member_is_static)

(set_member_access_specifier): Add an overload that takes a
reference to decl_base.
(set_member_is_static, set_member_function_{is_dtor, is_ctor,
is_const, vtable_offset, is_virtual}): Pass the member function as
a reference.): Add an overload that takes the member as a
reference, and write the older overload in terms of the new one.

Make decl_base::get_context_rel() return a naked pointer
Accessing the context relationship of declarations and setting some
member properties appear to be high in performance profiles due to
shared pointer handling. This patch makes the context relationship
accessors return a naked pointer and also passes a bunch of shared
pointer as references around.
* include/abg-fwd.h (set_member_is_static): Add an overload that
takes the member as a reference to a smart pointer.
(set_member_function_{is_dtor, is_ctor, is_const, vtable_offset,
is_virtual}): Pass the member function as a reference.
(set_member_function_is_const, set_member_function_is_virtual):
Pass the member function as a non-const reference.
* include/abg-ir.h (decl_base::get_context_rel): Return a naked
pointer.
(set_member_is_static, set_member_function_is_virtual): Adjust
this friend declaration.
(set_member_access_specifier): Add an overload that takes a
reference to the member. Pass a reference to smart pointer to the
other overload.
(set_member_function_is_{is_ctor,is_dtor,is_const,is_virtual,vtable_offset}):
Take a non-const reference to function_decl.
* src/abg-ir.cc (decl_base::get_context_rel): Likewise.
(equals(const decl_base&, const decl_base&, change_kind*)):
Adjust.

Likewise.

(set_member_is_static, set_member_function_{is_dtor, is_ctor,

a reference.): Add an overload that takes the member as a
reference, and write the older overload in terms of the new one.

Make applying supp specs through pointer access look through typedefs
Consider the declaration of the exported function bar() below:
struct _OpaqueType {int member;};
typedef struct _OpaqueType Type;
void bar(Type*);
Once the *definition of struct _OpaqueType and bar() are compiled into
a shared library, if a layout change happens to struct _OpaqueType,
then abidiff rightfully reports that bar() is impacted by the layout
change to struct _OpaqueType.
But then, the following suppression specification won't silence the
ABI change report:
[suppress_type]
name = _OpaqueType
type_kind = struct
accessed_through = pointer
This is because strictly speaking, it's not struct _OpaqueType that is
accessed through a pointer, from function bar(); it's the type 'Type',
(which is a typedef of struct _OpaqueType) that is accessed though a
pointer.
But then, as 'Type' and 'struct _OpaqueType' are the same type (modulo
the typedef), this behaviour is not super useful. It would be more
interesting if the suppression specification could silence the ABI
change report.
And this is what this patch does.

to the subjects of the diff, look through typedefs and try to
apply the suppression again.

Make type_has_non_canonicalized_subtype() tighter
type_has_non_canonicalized_subtype() gives up too quickly.
For instance, suppose it's looking a type 'foo'. If foo has no
canonicalized type yet and has a data member which type is foo* (for
instance), then type_has_non_canonicalized_subtype() just sees that
type 'foo*' has no canonicalized type, and so it returns, saying that
he found a non-canonicalized subtype for foo.
In that case though, what type_has_non_canonicalized_subtype() should
do is detect that foo* is a pointer to foo itself, so it shouldn't
count as a non-canonicalized sub-type. It should keep going and look
for other meaningful non-canonicalized sub-types.
And this what this patch does. It changes the sub-type walker that
type_has_non_canonicalized_subtype() uses, so that
- it doesn't flag sub-types that refer to the type we are looking
at as non-canonicalized sub-types. This is for sub-types that
are combinations of pointers, references and typedefs.
- it doesn't consider sub-types of member functions of the type we
are looking at, unless that member function is virtual.
The result is that more types are canonicalized early during DWARF
reading, and so there are less types to store on the side for late
canonicalization. This can have a big impact on, e.g, C++ libraries
with tens of thousands of types.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.

Make canonicalization non sensitive to struct-ness of subtypes
In a previous patch, we made canonicalization independant from
struct-ness of class types. This was in this commit:
0e3416e Bug 19023 - Type canonicalization is sensitive to struct-ness
But then, that didn't handle the case of composite types which have a
subtype of class type T, where the same T was declared as "struct" and
as "class" in the same binary.
This patch handles that case by passing a flag to the functions that
build the pretty representation of types. Note that the pretty
representation is used as a key in the hash map that contains
canonical types. That flag is passed all the way down to the function
that builds the pretty representation for class types, which decides
to use either "struct" or "class" as a previx for the representation.
The type canonicalization code then passes that flag (properly set) to
the pretty representation function.

Add support for abicompat weak mode

the application are compared to the types of the functions and

The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the

To do this a number of changes were necessary.

Make canonicalization non sensitive to struct-ness of subtypes
In a previous patch, we made canonicalization independant from
struct-ness of class types. This was in this commit:
0e3416e Bug 19023 - Type canonicalization is sensitive to struct-ness
But then, that didn't handle the case of composite types which have a
subtype of class type T, where the same T was declared as "struct" and
as "class" in the same binary.
This patch handles that case by passing a flag to the functions that
build the pretty representation of types. Note that the pretty
representation is used as a key in the hash map that contains
canonical types. That flag is passed all the way down to the function
that builds the pretty representation for class types, which decides
to use either "struct" or "class" as a previx for the representation.
The type canonicalization code then passes that flag (properly set) to
the pretty representation function.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.

Make canonicalization non sensitive to struct-ness of subtypes
In a previous patch, we made canonicalization independant from
struct-ness of class types. This was in this commit:
0e3416e Bug 19023 - Type canonicalization is sensitive to struct-ness
But then, that didn't handle the case of composite types which have a
subtype of class type T, where the same T was declared as "struct" and
as "class" in the same binary.
This patch handles that case by passing a flag to the functions that
build the pretty representation of types. Note that the pretty
representation is used as a key in the hash map that contains
canonical types. That flag is passed all the way down to the function
that builds the pretty representation for class types, which decides
to use either "struct" or "class" as a previx for the representation.
The type canonicalization code then passes that flag (properly set) to
the pretty representation function.

(get_method_type_name, get_pretty_representation): Add an
"internal" flag to all overoads.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.

Make canonicalization non sensitive to struct-ness of subtypes
In a previous patch, we made canonicalization independant from
struct-ness of class types. This was in this commit:
0e3416e Bug 19023 - Type canonicalization is sensitive to struct-ness
But then, that didn't handle the case of composite types which have a
subtype of class type T, where the same T was declared as "struct" and
as "class" in the same binary.
This patch handles that case by passing a flag to the functions that
build the pretty representation of types. Note that the pretty
representation is used as a key in the hash map that contains
canonical types. That flag is passed all the way down to the function
that builds the pretty representation for class types, which decides
to use either "struct" or "class" as a previx for the representation.
The type canonicalization code then passes that flag (properly set) to
the pretty representation function.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..

Make canonicalization non sensitive to struct-ness of subtypes
In a previous patch, we made canonicalization independant from
struct-ness of class types. This was in this commit:
0e3416e Bug 19023 - Type canonicalization is sensitive to struct-ness
But then, that didn't handle the case of composite types which have a
subtype of class type T, where the same T was declared as "struct" and
as "class" in the same binary.
This patch handles that case by passing a flag to the functions that
build the pretty representation of types. Note that the pretty
representation is used as a key in the hash map that contains
canonical types. That flag is passed all the way down to the function
that builds the pretty representation for class types, which decides
to use either "struct" or "class" as a previx for the representation.
The type canonicalization code then passes that flag (properly set) to
the pretty representation function.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.

Make canonicalization non sensitive to struct-ness of subtypes
In a previous patch, we made canonicalization independant from
struct-ness of class types. This was in this commit:
0e3416e Bug 19023 - Type canonicalization is sensitive to struct-ness
But then, that didn't handle the case of composite types which have a
subtype of class type T, where the same T was declared as "struct" and
as "class" in the same binary.
This patch handles that case by passing a flag to the functions that
build the pretty representation of types. Note that the pretty
representation is used as a key in the hash map that contains
canonical types. That flag is passed all the way down to the function
that builds the pretty representation for class types, which decides
to use either "struct" or "class" as a previx for the representation.
The type canonicalization code then passes that flag (properly set) to
the pretty representation function.

Make canonicalization non sensitive to struct-ness of subtypes
In a previous patch, we made canonicalization independant from
struct-ness of class types. This was in this commit:
0e3416e Bug 19023 - Type canonicalization is sensitive to struct-ness
But then, that didn't handle the case of composite types which have a
subtype of class type T, where the same T was declared as "struct" and
as "class" in the same binary.
This patch handles that case by passing a flag to the functions that
build the pretty representation of types. Note that the pretty
representation is used as a key in the hash map that contains
canonical types. That flag is passed all the way down to the function
that builds the pretty representation for class types, which decides
to use either "struct" or "class" as a previx for the representation.
The type canonicalization code then passes that flag (properly set) to
the pretty representation function.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.

Make canonicalization non sensitive to struct-ness of subtypes
In a previous patch, we made canonicalization independant from
struct-ness of class types. This was in this commit:
0e3416e Bug 19023 - Type canonicalization is sensitive to struct-ness
But then, that didn't handle the case of composite types which have a
subtype of class type T, where the same T was declared as "struct" and
as "class" in the same binary.
This patch handles that case by passing a flag to the functions that
build the pretty representation of types. Note that the pretty
representation is used as a key in the hash map that contains
canonical types. That flag is passed all the way down to the function
that builds the pretty representation for class types, which decides
to use either "struct" or "class" as a previx for the representation.
The type canonicalization code then passes that flag (properly set) to
the pretty representation function.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.

Make canonicalization non sensitive to struct-ness of subtypes
In a previous patch, we made canonicalization independant from
struct-ness of class types. This was in this commit:
0e3416e Bug 19023 - Type canonicalization is sensitive to struct-ness
But then, that didn't handle the case of composite types which have a
subtype of class type T, where the same T was declared as "struct" and
as "class" in the same binary.
This patch handles that case by passing a flag to the functions that
build the pretty representation of types. Note that the pretty
representation is used as a key in the hash map that contains
canonical types. That flag is passed all the way down to the function
that builds the pretty representation for class types, which decides
to use either "struct" or "class" as a previx for the representation.
The type canonicalization code then passes that flag (properly set) to
the pretty representation function.

Make canonicalization non sensitive to struct-ness of subtypes
In a previous patch, we made canonicalization independant from
struct-ness of class types. This was in this commit:
0e3416e Bug 19023 - Type canonicalization is sensitive to struct-ness
But then, that didn't handle the case of composite types which have a
subtype of class type T, where the same T was declared as "struct" and
as "class" in the same binary.
This patch handles that case by passing a flag to the functions that
build the pretty representation of types. Note that the pretty
representation is used as a key in the hash map that contains
canonical types. That flag is passed all the way down to the function
that builds the pretty representation for class types, which decides
to use either "struct" or "class" as a previx for the representation.
The type canonicalization code then passes that flag (properly set) to
the pretty representation function.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.

Make canonicalization non sensitive to struct-ness of subtypes
In a previous patch, we made canonicalization independant from
struct-ness of class types. This was in this commit:
0e3416e Bug 19023 - Type canonicalization is sensitive to struct-ness
But then, that didn't handle the case of composite types which have a
subtype of class type T, where the same T was declared as "struct" and
as "class" in the same binary.
This patch handles that case by passing a flag to the functions that
build the pretty representation of types. Note that the pretty
representation is used as a key in the hash map that contains
canonical types. That flag is passed all the way down to the function
that builds the pretty representation for class types, which decides
to use either "struct" or "class" as a previx for the representation.
The type canonicalization code then passes that flag (properly set) to
the pretty representation function.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.

Make canonicalization non sensitive to struct-ness of subtypes
In a previous patch, we made canonicalization independant from
struct-ness of class types. This was in this commit:
0e3416e Bug 19023 - Type canonicalization is sensitive to struct-ness
But then, that didn't handle the case of composite types which have a
subtype of class type T, where the same T was declared as "struct" and
as "class" in the same binary.
This patch handles that case by passing a flag to the functions that
build the pretty representation of types. Note that the pretty
representation is used as a key in the hash map that contains
canonical types. That flag is passed all the way down to the function
that builds the pretty representation for class types, which decides
to use either "struct" or "class" as a previx for the representation.
The type canonicalization code then passes that flag (properly set) to
the pretty representation function.
* include/abg-fwd.h (get_type_name, get_function_type_name)

"internal" flag to all overoads.

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.

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.

Delay non-complete class type resolution up to end of corpus reading
From the DWARF emitted by GCC 4.4.7 for libstdc++ we encountered an
interesting construct.
A non-complete version of std::runtime_error is declared in
libstdc++-v3/src/functexcept.cc and is represented in DWARF as:
[ 37344] class_type
name (strp) "runtime_error"
declaration (flag)
Then a bit later, that *non-complete* class is used as a base class
for a class, *without* being fully defined! This shouldn't happen
but, well, it does:
[ 3b3a1] class_type
specification (ref4) [ 3733e]
byte_size (data1) 16
decl_file (data1) 5
decl_line (data1) 141
containing_type (ref4) [ 3734a]
sibling (ref4) [3b405]
[ 3b3b1] inheritance
type (ref4) [ 37344] <---- here.
The thing is that, later, in another translation unit
(libstdc++-v3/src/stdexcept.cc), that same class is defined fully:
[ 7e9f9] class_type
name (strp) "runtime_error"
declaration (flag)
[...]
[ 80c95] class_type
specification (ref4) [ 7e9f9]
byte_size (data1) 16
decl_file (data1) 4
decl_line (data1) 108
containing_type (ref4) [ 7e9ff]
sibling (ref4) [ 80d2b]
[...] <---------- and the definition goes here.
But then you see that the DIE offset of the "version" of the
runtime_error class that is "defined" libstdc++-v3/src/stdexcept.cc in
is different from the version that is only declared in
libstdc++-v3/src/functexcept.cc. But virtue of the "One Definition
Rule", we can assume that they designate the same type. But still,
runtime_error should have been defined in
libstdc++-v3/src/stdexcept.cc. Anyhow, libabigail needs to be able to
handle this. That is, it needs to wait until the entire ABI corpus is
loaded from DWARF, then lookup the definition of all the non-complete
types we have encountered.
And then only after that non-complete type resolution has taken place,
we can proceed with type canonicalizing, rather than doing it after
the loading of each translation unit like what we were doing
previously.
This is what this patch does.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.

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)

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just

the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the

The abicompat first gets the set of symbols undefined in the

declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the

To do this a number of changes were necessary.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.

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.

Introduce the concept of environment
There are resources needed by the type system and other artifacts of
libabigail. Today, when the life time of those resources need to be
greater than all of artifacts of Abigail, then said resources are made
global.
But then global resources are not great, if anything because they
complicate the future use of the library in concurrent computing
setups.
As I was in the need to add one resource to be used by the type
system, I decided to sit down and first overhaul how these long lived
resources needed to be handled.
And here comes the concept of "environment". An environment is a
place where one can put resources that need to live longer than all
the other artifacts of the Abigail system. And so, the code that
creates Abigail artifacts needs and environment of for said artifacts
to use. In other words, artifacts now use an environment.
This has interesting and strong implications. We can only compare two
artifacts if they use the same environment. This is quite a strong
requirement.
But then when this requirement is fulfilled, comparing two types
amounts to just comparing two pointer values; hash values for types
can also be cached. Now *that* is great for speed of comparison, is
it not?
This patch introduce the concept environment (which is basically a new
abigail::ir::environment type), removes the global variables and uses
the environment instead. Each ABI artifact (either type or decl) now
has a ::get_environment() member function to get its environment.
This patch also disables the caching of hash values because the
caching must happen only *after* all types have been canonicalized.
We were not respecting that requirement until now, and that introduces
wrong hash values. A subsequent patch is going to re-introduce hash
value caching again, once the infrastructure is in place to set a flag
in the environment (hah!) once type canonicalization is done, and then
later read that flag when some client code requests a hash value, to
know if we should look in the hash value cache or not.
The patch obviously changes the output of numerous regression tests
(if anything b/c it disables hash value caching) so 'make check'
yields regressions. But then, it's only the subsequent patch that
updates the tests.

Canonicalize types either early or late after TU reading
While trying to diff two identical files (abidiff foo.so foo.so) it
appeared that canonicalizing types during e.g, the DWARF reading
process was leading to subtle errors because it's extremely hard to
know when a type is complete. That is, during the building of a class
type C, a pointer to C can be built before C is complete. Worse, even
after reading the DIE (from DWARF) of class C, there can be DIE seen
later in the translation unit that modifies type C. In these late
cases, one needs to wait -- not only until C is fully built, but also
sometimes, after the translation unit is fully built -- to
canonicalize C and then the pointer to C. This kind of things.
So now there are two possible points in time when canonicalization of
a type can happen. It can happen early, when the type is built. This
is the case for basic types and composite types for which all
sub-types are canonicalized already. It can happen late, right after
we've finished reading the debug info for the current translation
unit.
So this patch fixes the IR traversal and uses that to walk the
translation unit (or even types) after it's built. It does away with
the first attempt to perform early canonicalizing only.
The patch also handles type canonicalizing while reading xml-abi
format.
* include/abg-fwd.h (is_class_type)

take virtual member functions in account when comparing the

DIEs that change the number of virtual member functions after the
DIE of the class. So one needs to start taking virtual members
into account only after the translation unit has been constructed.

(build_function_decl): Fix the function type canonicalizing (per

Handle the canonicalizing for these composite types: either early
or late.

to know that it should leave a class alone until it's fully built.

Make type_has_non_canonicalized_subtype() tighter
type_has_non_canonicalized_subtype() gives up too quickly.
For instance, suppose it's looking a type 'foo'. If foo has no
canonicalized type yet and has a data member which type is foo* (for
instance), then type_has_non_canonicalized_subtype() just sees that
type 'foo*' has no canonicalized type, and so it returns, saying that
he found a non-canonicalized subtype for foo.
In that case though, what type_has_non_canonicalized_subtype() should
do is detect that foo* is a pointer to foo itself, so it shouldn't
count as a non-canonicalized sub-type. It should keep going and look
for other meaningful non-canonicalized sub-types.
And this what this patch does. It changes the sub-type walker that
type_has_non_canonicalized_subtype() uses, so that
- it doesn't flag sub-types that refer to the type we are looking
at as non-canonicalized sub-types. This is for sub-types that
are combinations of pointers, references and typedefs.
- it doesn't consider sub-types of member functions of the type we
are looking at, unless that member function is virtual.
The result is that more types are canonicalized early during DWARF
reading, and so there are less types to store on the side for late
canonicalization. This can have a big impact on, e.g, C++ libraries
with tens of thousands of types.

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

(build_function_decl): Fix the function type canonicalizing (per
translation) that was already in place. Do the canonicalizing of
these only when the type is fully built. Oops. This was really
brokend. Also, when the function type is constructed, consider it
for type canonicalizing.

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

regression testing script to the build system.

Declaration-only classes shouldn't have canonical types
I am seeing issues related to the fact that a declaration-only class A
would compare different to the full version of class A. This is due
to the fact that that the declaration-only A and the full A have
different hashes, even though they structurally compare equal. So
they have different canonical types, with the current code. This
patch arranges for declaration-only classes to have no canonical type,
forcing it to compare structurally to other types. Then the patch
adjusts strip_typedef() that used to expect that all types it sees
have canonical types. Then the patch changes the type hashing code to
avoid making it cache their hash, because otherwise, in some cases
when we hash a type (too) early, a temporary hash of it gets stored ad
infinitum, even after the type has been later updated. Last but not
least, the patch returns a zero hash for declaration-only classes.
* include/abg-fwd.h (keep_type_alive): Declare new function.
* src/abg-ir.cc (strip_typedef): Simplify logic. Support types
that are not canonicalized.
(type_base::get_canonical_type_for): For declaration-only classes,
return an empty canonical class, forcing the class to be compared
structurally.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.
