Fix symlinks paths handling in abipkgdiff
When elements of an RPMs are referred to using a path that contains symlinks, we need to resolve the symlinks in order to be able to compare those paths. We are not doing this fully and so we are hitting corner cases where things break down in subtle ways. This patch fixes that. * include/abg-tools-utils.h (real_path): Declare new function. * src/abg-tools-utils.cc (real_path): Define it. * tools/abipkgdiff.cc (package::convert_path_to_relative): Use the new real_path function to consider real path (where symlinks are resolved) of the extraction directory of the package. (get_interesting_files_under_dir): Similarly, use the new real_path function to consider the real path of the directory we are exploring. Signed-off-by: Dodji Seketeli <dodji@redhat.com> |

Bug 22692 - Consider Java as a language that supports the ODR
While comparing libgcj.so, it turned out that we are trying to canonicalize a DW_TAG_class_type DIE expressing a Java type. Right now, we don't canonicalize DW_TAG_class_type yet because languages that emit those DIEs (like C++) do respect the One Definition Rule. So in theory, we do not need to canonicalize the DW_TAG_class_type by using structural comparison. We only perform DIE canonicalization of DIEs originating from the C language as that language does not respect the ODR. We were assuming that only C++ actually respects the ODR. In practise, Java does also, so this patch now assumes that C++ and Java respect the ODR. So when facing DIEs originating from those languages, we don't try (yet) to canonicalize their DIEs. In the future though, we need to canonicalize all DIEs, irrespective of the language they originated from. And for that, we need to support structural comparison of DW_TAG_class_type DIEs, among others. * include/abg-ir.h (is_java_language): Declare new function. * src/abg-dwarf-reader.cc (odr_is_relevant): Adjust to consider that Java also respects the ODR. * src/abg-ir.cc (is_java_language): Define new function.

Fix version revision number printing in tools --help option

Bug 22438 - Emit a clear message when debug info is not found
The alternate debug info file referred to a binary can be missing, even though the rest of the debug info is not. In that case, libabigail starts loading the debug info and then it crashes when trying to get DIEs that are part of the missing alternate debug info. This patch detects when the alternate debug info is missing, so that abidiff and abipkgdiff can gracefully bail out, yielding a meaningful error message. * include/abg-dwarf-reader.h (enum abigail::dwarf_reader::status): Add a new STATUS_ALT_DEBUG_INFO_NOT_FOUND enumerator there. (refers_to_alt_debug_info): Declare new function. * src/abg-dwarf-reader.cc (read_corpus_from_elf): Detect when the referred-to alternate debug info file is not found and flip the STATUS_ALT_DEBUG_INFO_NOT_FOUND bit of the status accordingly. If the debug info was found but not the alternate debug info, then do not try to read the debug info at all. (refers_to_alt_debug_info): Define new function. * tools/abidiff.cc (handle_error): Define new static function. (main): Use it, rather than handling errors preventing libabigail from reading the corpus on a case by case basis. tools/abipkgdiff.cc (compare): Handle the case where no alternate debug info was found. * tests/data/test-diff-pkg/libxfce4ui-devel-4.12.1-8.fc27.ppc64-self-report-0.txt: New test output reference. * tests/data/test-diff-pkg/libxfce4ui-devel-4.12.1-8.fc27.ppc64.rpm: New test input RPM. * tests/data/test-diff-pkg/libxfce4ui-devel-debuginfo-4.12.1-8.fc27.ppc64.rpm: Likewise. * tests/data/Makefile.am: Add the new test files above to source distribution. * tests/test-diff-pkg.cc (in_out_specs): Add a new test case from the new input files above.

Allow setting options to instances of xml_writer::write_context
Up to know, it wasn't possible to set options to instances of
xml_writer::write_context. So it wasn't possible to, say, make abidw
stop emitting source locations in the abixml.
This patch does the work necessary to set two options: annotate and
show locations. Note that the patch doesn't yet enable abidw to stop
emitting source locations. That will be done in a subsequent patch.
* include/abg-writer.h (create_write_context, set_show_locs)

the annotate parameters as these can be retrieved from the

(write_context::write_context): Initialize it.
(write_context::{get_show_locs, set_show_locs}): Add new member

(write_location): Take a write_context, rather than an output
stream. From the context, we detect if the user did set the "show
loc" option and act accordingly. Write the second overload in
terms of the first one.

(write_function_tdecl, write_class_tdecl): Adjust the invocation
of write_location.
(write_corpus, write_corpus_group): Remove the output stream and
the annotate parameters as these can be retrieved from the
context. Adjust.
* tools/abidw.c: (load_corpus_and_write_abixml): Create a
write_context object, set the 'annotate' option to it and use that
object to actually write out the corpus.

Initial implementation of a --leaf-changes-only option to abidiff
This patch allows abidiff to take the --leaf-changes-only option and
then to display only the changes that are local to any given type.
That means the reporting agent won't follow pointers when displaying
changes. That gives less context to the ABI change reports but then
they are less cluttered.
To do this, the patch introduces a new reporting agent to libabigail:
abigail::comparison::leaf_reporter. When given a graph of diff nodes,
this agent only reports about the leaf (local) changes. That is, it
will *NOT* follow pointers, references, underlying types of qualified
and typedef types and things like that. It will just report about
changes that are local to a given type.
This reporting agent is then used (in lieu of the default
abigail::comparison::default_reporter agent) when the
--leaf-changes-only option is provided by the user on the command line
of abidiff.
Note that abidiff also takes the --impacted-interfaces option to so
that the leaf reporter shows the set of interfaces impacted
by each leaf change.

--leaf-changes-only and --impacted-interfaces options.

Allow several kinds of reports to be emitted
Right now, the reporting functionnality is implemented directly in the
comparison engine. Being able to emit several kinds of reports is
really not practical with the current design.
This patch improves that situation by introducing an indirection
between the comparison engine and the code that emits the report.
A new abigail::comparison::reporter_base type is introduced. That
type several contains virtual methods that knows how to implement
reporting. Each virtual method reports about changes carried by a
kind of diff node. In other words, abigail::comparison::reporter_base
is the interface of reporter objects.
The current reporting using the current format is thus implemented by
the new abigail::comparison::default_reporter type, which implements
the abigail::comparison::reporter_base interface.
The diff::report methods now "just" get the reporter object from the
context of the diff and invoke its right reporting interface.
So whenever someone needs to implement a new reporting format, she
needs to provide a new implementation of the
abigail::comparison::reporter_base interface and set it to the
diff_context prior to invoking the
abigail::comparison::corpus_diff::report() method.

Bug 21730 - Make abipkgdiff compare Linux Kernel packages as expected
This is the initial patch that makes abipkgdiff recognize Linux kernel packages passed in argument and do the right thing. abipkgdiff gets the vmlinux binary from the debug info package, considers the union of that vmlinux binary and the thousands of kernel modules that we shall name "the Kernel".

Bug 21627 - Libabigail doesn't consider translation unit compile dir
The path of a translation unit is relative to the directory where that translation unit was compiled. So there can be several different translation units (in the same binary) that have the same (relative) paths. To tell them apart, one needs to consider the compile directory of those translation units. But then Libabigail ignores the compilation directory of translation units. It just considers their (relative) path. That leads to different translation units having the same path. Furthermore, there can be a translation unit with full path (one that takes into account the file name and its compile directory) named "P" that contains function definitions f1 and f2, as described by the debug info. Further down the road, there can be *another* translation unit which also has "P" as its full path, and that cotnains function definitions f3 and f4. A way to understand is to consider that the translation unit of full path "P" contains f1, f2, f3 and f4. This patch introduces the concept of the compile dir of a given translation unit, and the concept of the absolute path of the translation unit which would then be a concatenation of the compile dir and relative paths of the translation unit. The patch also tries to reuse a translation unit with a given path, *if* that translation unit has already been seen in the current binary, instead of creating a new one altogether. This patch doesn't carry a regression test as the problem was found while running the https://pagure.io/libabigail-selfcheck/blob/master/f/selfcheck.py script over the Fedora 25 critpath packages. The patch does however update existing reference outputs of existings tests where appropriate. * include/abg-ir.h (translation_unit::{get_compilation_dir_path, set_compilation_dir_path, get_absolute_path}): * src/abg-corpus.cc (corpus::add): Use the new translation_unit::get_absolute_path() as the key for the tu path -> tu map. * src/abg-dwarf-reader.cc (read_context::resolve_declaration_only_classes): Use the new translation_unit::get_absolute_path().

Allow re-using the ELF/DWARF read_context when loading a corpus group
Right now, when loading each corpus of a group, a new read_context is created and destroyed. That makes thousands of corpora that are created and destroyed.

Add --vmlinux{1,2} option to abidw and kmidiff
When using abidw to generate an abixml for a Linux Kernel build tree,
usually, people have to copy the vmlinux binary into the directory
where modules are, so that the tool can find it. This --vmlinux
option helps to avoid doing that copy.
Simarly, when comparing two Linux Kernel build trees, --vmlinux1 and
--vmlinux2 are there to make the tool find the vmlinux binaries to
compare, independantly from the directories under which the modules
are to be found.

Do not report about voffset when it's not set in debug info
Sometimes some virtual member functions don't have any virtual offset set in the debug info. This happens for virtual destructors sometimes.

Allow selective resolution of class declaration
When a class is forward-declared, resolving it to a definition that
appears later in the same translation unit or in another translation
is an interesting problem.
Until now, the declaration would be resolved to the definition of that
class found in the binary. The problem is that there can be different
such definitions, especially in C where there is no "One Definition
Rule". In that case, the definition chosen is random.
This patch resolves that randomness.
For a given class declaration, if there is just one possible
definition in the binary, then the declaration is resolved to that
definition. If there is one definition for that declaration in the
same translation unit, then the declaration is resolved to that
definition. If there are more than one definitions in translation
units that are not the one of the declaration, then the declaration is
left unresolved. This is what I call "selective class declaration resolution".
Note that an unresolved class declaration now compares different to a
definition of a class of the same name. This is so that we can have
an unresolved class be present in the resulting .abi file, alongside
an (incompatible) definition of the same class. The change from a class
declaration to its definition is filtered out by default, though.

Initial support of de-serializing the KMI of a Linux Kernel Tree
With this patch, kmidiff knows how to compare a serialized
corpus_group that represents a Kernel Module Interface (a .kmi file)
against either another serialized .kmi file, or against a kernel tree.
The patch extends the abixml reader to make it parse an
'abi-corpus-group' element. To do that, the patch modifies
read_corpus_from_input to make it be capable of parsing several
'abi-corpus' in a row. That modified function is then used by a new
read_corpus_group_from_input, which is itself used by the new public
entry points read_corpus_group_from_native_xml_file and
read_corpus_group_from_native_xml.
With that read_corpus_group_from_native_xml_file building block
function, the kmidiff program is modified so that it can take either
two directory trees, two .kmi files or one directory tree and one .kmi
file.

Declare new function.
* src/abg-libxml-utils.cc (go_to_next_sibling_element_or_stay)

(read_translation_unit_from_input): Cleanup logic.
(read_corpus_from_input): Don't assume that the document is
starting with an 'abi-corpus' element. Support the mode where a
caller called the xmlTextReaderExpand function (and so we are
given an expanded xmlNodePtr) and the mode where we need to use
the xmlTextReader API to walk through the 'abi-corpus' element.
Also, if we are building a corpus group, do not clear what used to
be 'per-corpus' data. That data must be shared by all the corpora
of a given abi-corpus-group.

Initial support of the serialization of the KMI of a Linux Kernel Tree
We have the kmidiff program that takes two Linux Kernel trees containing the vmlinux binary and its modules and compare their Kernel Module Interface, aka KMI. We need to be able to serialize (save in a file) a representation of that KMI. We need to load that KMI back, and compare two serialized KMIs. This patch implements the serialization of the KMI of a Linux Kernel tree. It actually serializes an instance of abigail::ir::corpus_group that is a collection of instances of abigail::ir::corpus. The KMI of each individual binary (vmlinux or kernel module) is represented by one abigail::ir::corpus. All the corpora share the same definitions of types and decls, whenever that makes sense. The patch thus factorizes the routines used to walk a Linux kernel out of the kmidiff program. These routines are then re-used in the abidw program to make it walk a Linux kernel tree (when the --linux-tree option is provided), load the vmlinux and module binaries as an instance of abigail::corpus_group and serialize it out into an output stream. * include/abg-tools-utils.h (check_dir) (get_binary_paths_from_kernel_dist) (build_corpus_group_from_kernel_dist_under): Declare new functions. The last two functions are being moved from tools/kmidiff.cc so that they can be re-used. * include/abg-writer.h (write_corpus): Declare one overload that takes a write_context parameter.

Avoid building DIE -> parent DIE map when analyzing a C binary
The C language doesn't support namespaces. So, in that language, the
context of a type is always the global scope. Hence, the context of a
type DIE is always the global context associated to the current
translation unit.
Thus, when we are analyzing a C binary, we can do away with building
the DIE -> DIE parent map that we later use to get the parent of a
type DIE when we need to determine the context of a given type DIE.
This can save significant time and space.
This patch implements this optimization.

Speed up access to the definition of a class declaration-only type
While emitting an abixml output for a corpus_group representing the
KMI of a Linux kernel tree, profiling shows that during comparison of
class types, calling class_decl::get_definition_of_declaration is a
hotspot. Especially, the fact the function returns a shared pointer
that has to be "handled" shows up in the profile.
This patch introduces a
class_decl::get_naked_definition_of_declaration that returns a
pointer. Not a shared pointer.
The patch then uses that get_naked_definition_of_declaration function
in the comparison code for class_decl.
The patch also uses get_naked_canonical_type instead of
get_canonical_type when comparing a bunch of other types.
This makes things a little bit faster when compiled without
optimization between 2% and 5%.
* include/abg-ir.h
(class_or_union::get_naked_definition_of_declaration): Declare a
new member function.

Don't consider changes to basic types as being redundant
Suppose we have two types struct A and struct B. Suppose the two types have members of integer type. Suppose there are members of integer type in struct A that are modified to become members of char type. Suppose, at last, that we also have members of integer type in struct B that are modified to become members of char type. In that case, we want to see all the changes of members which types got changed from integer type to char type. None of these changes should be considered redundant.

Bug 21296 - Reporting diff of const ref against non-const ref aborts
References are always const. But then GCC sometimes emits DWARF that represents a const reference. This leads, for instance, to a given reference to be considered as different from that same reference wraps into a const qualifier. Which is wrong. Libabigail then represents those const references as a particular case of a "no-op qualifier". That is, a qualifier that should be ignored by the comparison code. In the case of this issue, the comparison engine considers the two references (const and non-const) to be equal, but the reporting code forgets to ignore the ignore no-op qualifier and thus (wrongly) considers the two references as being different. That inconsistency leads to an abort of the process. This patch moves the code that ignores no-op qualifiers at a lower level of the comparison engine so that whenever function parameters are compared, no-op qualifiers are ignored as they should. * include/abg-fwd.h (look_through_no_op_qualified_type): Declare new function. * src/abg-ir.cc (look_through_no_op_qualified_type): Define it.

Bug 21228 - Handle cloning union member functions
It turns out we allow member function cloning only for functions that are members of classes, not for functions that are member of unions. This patch fixes that by turning the method class_decl::add_member_function into the class_or_union::add_member_function. Note that there was already an overload of class_or_union::add_member_function; now, all the member functions add_member_function are members of the class_or_union type. The patch then modifies function_decl::clone to make that code avoid assuming that only member functions of classes can be cloned. * include/abg-ir.h (class_or_union::add_member_function): Move the class_decl::add_member_function overload declaration into the class class_or_union class.

Make sure that when setting the virtual-ness attributes of the member function, we are effectively looking at the a function that is a member of a class.

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

Bug 20476 - Compare virtual member functions when comparing classes
There are cases where a virtual member function doesn't have an implementation that is defined and publicly exported. This is the cases for virtual pure classes. Even in those cases, users might want to detect vtable changes on virtual member pure classes (interfaces). Now that, for C++ binaries, all the partial representations of a class are merged into one class (in a given binary), we can envision to compare virtual member functions of classes as part of comparing two classes. This is what this patch does. While comparing two classes, the virtual member functions are compared too. Note that as there can be several virtual member functions that have the same vtable offset (think about a virtual destructor that might have several generated functions that 'conceptually' share the same vtable offset), comparing the virtual functions can be a little bit non-trivial. The approach taken is to check that in the first set of virtual functions, each virtual function actually matches at least one virtual function in the second set. And the match is a "loose" one. That is, it doesn't take into account the symbol name or the mangled name. The patch also fixes the "less than" operator used to sort virtual member functions. There is also a buglet in the way we compute the highest vtable offset number today. This patch provides a new function named class_decl::get_biggest_vtable_offset that is used in the change reports. The patch also fixes a related bug in where we were forgetting to report about added and removed virtual member functions without an associated elf symbol. This patch fixes that. * include/abg-ir.h (class_decl::get_biggest_vtable_offset): Declare new member function. * src/abg-ir.cc (virtual_member_function_less_than::operator()): Either compare the symbol id strings if the functions have symbols or just compare their pretty representations.

Fix suppression category propagation in diff node graph
Under certain circumstances, a diff node (which we shall name N) that
belongs to the SUPPRESSED_CATEGORY category sees its belonging to that
category been propagated to its parent diff node, effectively
suppressing that parent diff node as well. This is how some function
diff nodes ends up being suppressed just because some of their
children diff nodes were suppressed.
This suppression category propagation is performed by a pass that
walks the diff nodes graph. To avoid infinite cycles, the pass avoids
visiting a diff node that is equivalent to a node that has already
been visited.
As a result, diff nodes equivalent to N (the class of equivalence of
N) are not traversed by the propagation pass. So their parent diff
nodes are not suppressed.
This leads to some functions not being suppressed as they should.
This phenomenon can be observed by comparing the two packages that are
provided in the regression test accompanying this patch using
abipkgdiff with the --redundant option.
Here is how the patch addresses the issue.
When the suppression category propagation pass considers a parent diff
node (named P) of a node N' (with N' being equivalent to N), it now
looks at the category of the *class of equivalence of N'* to determine
if that category should be propagated to P.
Previously, that pass would just look at the at the category of N'
(not the category of the class of equivalence of N') for the
propagation. But as N' has not been visited (because N has already
been visited and nodes equivalent to N are thus not visited) the
belonging of N' to the SUPPRESSED_CATEGORY hasn't been updated. So N'
isn't marked as being in SUPPRESSED_CATEGORY. So the
SUPPRESSED_CATEGORY wouldn't be propagated to P as it should.
So, with this patch abipkgdiff invoked with the --redundant option now
correctly yields:
$ abipkgdiff --redundant --d1 spice-debuginfo-0.12.4-19.el7.x86_64.rpm --d2 spice-debuginfo-0.12.8-1.el7.x86_64.rpm --devel1 spice-server-devel-0.12.4-19.el7.x86_64.rpm --devel2 spice-server-devel-0.12.8-1.el7.x86_64.rpm spice-server-0.12.4-19.el7.x86_64.rpm spice-server-0.12.8-1.el7.x86_64.rpm

Support virtual member functions with vtable offset not yet set
When reading C++ class informatin DWARF, it can happen that a given virtual member function does not yet have a vtable offset. Right now, that offset is set to zero. Just like a virtual member function which actual vtable offset is zero. So we don't make a difference between a virtual function with no vtable offset and a virtual function with a vtable offset set to zero. This can lead to confusions during class comparison. This patch fixes that problem by setting the default vtable offset to -1. So whenever a vtable offset is -1 it means that the virtual member function doesn't yet have a vtable offset. * include/abg-fwd.h (member_function_has_vtable_offset): Declare new function. (get_member_function_vtable_offset): Return a ssize_t, not a size_t. (set_member_function_vtable_offset): Take a ssize_t, not a size_t. * include/abg-ir.h (class_decl::virtual_mem_fn_map_type): Adjust the map typedef to make it take ssize_t as the type of the key.

Handle several virtual member functions having the same vtable offset
In the DWARF for C++, it can happens that a virtual constructor leads to several (up to 3) destructor functions that all have the same vtable offset. That vtable offset is the same as the offset of the virtual destructor that the user actually defined in her source code. This patch adds a map data structure to the private data of class_decl. That map associates a vtable offset X to a vector of virtual member functions that have the same vtable offset X. That new map is populated whenever a virtual member function is added to the class. * include/abg-ir.h (class_or_union::virtual_mem_fn_map_type): Define new typedef. (class_decl::get_virtual_mem_fns_map): Declare new accessor. * src/abg-ir.cc (class_decl::priv::virtual_mem_fns_map_): New data member. (class_decl::get_virtual_mem_fns_map): Define new accessor.

Speed up pretty representing (function) types
During structural (function) type comparison, computing the pretty
representation of the type at hand appears high on performance profiles,
especially when type canonicalization wasn't really effective.
This patch adds a type_base::get_cached_pretty_representation() and a
function_type::get_cached_name() to cache the pretty representation of
a type, as well as the function type name. This is way, the type
representation is computed just once and stored into a cache.
subsequent invocations of the function just look into the cache
instead of computing the representation again.
Note that we do this only for non-canonicalized types because these
types can still be modified, and so caching the representation of a
type that might be changed (and thus see its representation change)
leads to issue. So the representation of non-canonicalized types is
not cached.
* include/abg-ir.h (type_base::get_cached_pretty_representation):
Declare new function.
(function_type::get_cached_name): Likewise.
* src/abg-ir.cc (get_method_type_name): Use the new

function.
(function_type::get_cached_name): Likewise.
(type_base::get_canonical_type_for): Call
type_base::get_cached_pretty_representation here, so the internal
representation is cached right before canonicalization.
(function_type::{mark_as_being_compared, unmark_as_being_compared,
comparison_started}): Uset he new type_base::get_cached_name to
speed up function type name retrieval.

Fix performance regression while analyzing libjvm.so
abidiff libjvm.so libjvm.so is taking forever in the master branch
these days. At some point it was taking ~ 15 minutes and 15GB of RAM
on a non-optimized build.
Profiling of CPU usage showed that sorting virtual member
functions of a class whenever a new virtual member function is added
was the hot spot.
This patch now sorts virtual member functions once right after the
type was canonicalized. The patch adds a virtual function
type_base::on_canonical_type_set() that is invoked right after the
canonical type is set for a given type. class_decl gets its own
version of that virtual function: class_decl::on_canonical_type_set.
In that function, the patch does sort the virtual member functions of
the current class_decl.
Now with this patch, abidiff is still taking around 15 minutes but it
consumes less than 12GB of ram. This means the memory consumption was
reduced by 20%. abipkgdiff performs on 16:30 minutes and in less than
12GB of RAM as well. All these times are measured on a non-optimized
build.

Support Linux Kernel ABI whitelist files
Enterprise Linux (at least) kernels come with ABI whitelist files that list the names of the set of functions to be considered when looking at the ABI exposed by the kernel to its modules. This patch adds a new --linux-kernel-abi-whitelist option to abidiff so that it drops changes that relate to functions that are *NOT* defined in the whitelist.

Support Linux Kernel binaries
This patch teaches the ELF/DWARF reader of libabigail to load special
ELF sections that are specific to Linux Kernel binaries (either
vmlinux or linux kernel modules).
The patch creates a new flag that tells the ELF reader that it needs
to consider the input binary as a Linux Kernel binary. This is the
new 'Linux Kernel mode'.
In this linux kernel mode, the reader expects sections that are named
__ksymtab and/or __ksymtab_gpl sections. Those sections contain
indexes (of ELF symbols described in the normal ELF symbol table) of
exported ELF symbols that are specifically marked by developers using
EXPORT_SYMBOL or EXPORT_SYMBOL_GPL macros. These are symbols of
global variables and functions defined and meant to be used by kernel
modules. They constitute the interface exported by the Linux Kernel
to its modules. So the patch only exports the publicly defined and
exported ELF symbols that are also listed in __ksymtab and
__ksymtab_gpl sections.
The patch also fixes and re-organizes things left and right so that
this new mode works in a well integrated manner with the other parts
of the reader:
- The load address of the binary is no more assumed to be the load
address specified by the program header that is at offset zero.
This is usually the case for user-space programs. To handle Linux
Kernel binaries, the load address is now the one specified by the
program header that is at the smallest offset.
- The patch now tries to populate the various symbol maps only when
necessary. That way, the new symbol maps defined for the ksymtab
and ksymtab_gpl section are also loaded only when necessary; that
is, when in Linux Kernel mode.
- The patch (more) agressively suppresses non-member functions or
variables that are not declarations and that have no associated
ELF symbol.
The patch knows how to recognize and read relevant ELF symbol
information from __ksymtab and __ksymtab_gpl sections.
The patch makes abidiff and abidw detect that a binary is a
Linux Kernel binary (either a vmlinux or a module). It does this by
detecting the presence of the speciall __ksymtab_strings section.
If it detects that a binary is a Linux Kernel binary then it only
considers functions and variables which are defined and exported in
the sense of ELF *AND* which ELF symbols are listed in the __ksymtab
and __ksymtab_gpl sections.
If users want abidiff and abidw to consider their input binaries as
normal ELF binaries then they can use the option --no-linux-kernel-mode.

Handle per translation unit and per corpus types maps
Today, whenever a type is added to its scope, a map that associates the qualified type name to the type is updated. There is only one such map in a given ABI corpus. So whenever a type is looked up from its name, it's that per-corpus type map that is used. This setup makes libabigail type lookup be tailored only for binaries that respect the One Definition Rule of C++[1] (aka ODR) which basically says that there should be only one type of a given name in an ABI corpus. It turns out that many binaries, especically C binaries, don't respect the ODR. So a type "struct foo" can be defined in a file a.c and another *different* type "struct foo" can also be defined in b.c. What a useful and safe feature! Not. For those binaries, just having one type map doesn't work. We need to have one type map per translation unit, and one map per-corpus map. This is the strategy implemented by this patch. With this patch, whenever a type is added to its scope, a per translation unit type map is updated. The per corpus map is updated as well. If there are more than one type of a given name, the entry in the per corpus type map for that type is left empty. Type lookup now potentially becomes a two phases lookup. Whenever a type is looked up from its name, the per corpus type map is looked at first. If the type is not in that per corpus type map, then the per translation unit type maps are lookup up, in sequence. The patch thus re-visits the type maps updating and lookup routines to adapt them to the new scheme. The patch also updates the clients of the type map updating and lookup code. Note that this patch is part of a series of patches which aims to move libabigails away from its ODR-centric organization to make it work well also on binary where the ODR is not relevant. As such, the patch doesn't assure that "make check" passes. To have "make check" pass, you need to have all the patches of the series applied.

Make abg-fwd.h use *_sptr typedefs
Until now, the abg-fwd.h where the necessary forward generic declarations where put didn't contain the convenience typedefs of the form foo_sptr that designate a shared pointer to type foo.

Bug 20887 - Show relative change of offsets
Until now, an offset change is reported by showing the old and new
offsets of the data member that changed.
This patch adds the string "(by +N bits)" with 'N' being the number of
bits by which the offset of the data member was increased, or "(by -N
bits) if the offset of the data member was decreased of N bits.
The patch also emits a string that says "size hasn't changed" if the
size of the structure did not change.
This can be disabled by a new --no-show-relative-offset-changes
option.

Very light speed improvements
When comparing of two kernel trees showed that for huge changesets
involving highly recursive types, leaf functions used by the
categorization code dominate the performance profile.

different types) in the general case where types are
canonicalized.

Introduce on-the-fly type canonicalization
During canonicalization of a type T, when T is structurally compared
to an already canonicalized type C, it can happen that
non-canonicalized sub-types of T are structurally compared again and
again to canonicalized sub-types of C.
This patch introduces a new optimization or those cases: on-the-fly
type canonicalized.
That means, if a not-yet-canonicalized sub-type S of the type T being
canonicalized structurally compares equal to a canonicalized sub-type,
then the canonical type of S is said to be the canonical type of the
canonicalized sub-type. So sub-type S is canonicalized, on-the-fly,
during canonicalization of type T.
This considerably speeds up the canonicalization process while doing
"abidiff vmlinux vmlinux". It goes from taking forever to taking 45
seconds on a non-optimized build.

Fix pretty representation of array types
It turned out we were wrongly emitting the pretty representation of array types in two cases: 1/ in case of qualified array types: a const array of string type was being pretty-represented as: "const string[]" instead of "string[] const". 2/ in case of array with an empty sub-range DIE; that is a sub-range DIE with no attribute at all. For instance an array of char with an empty sub-range DIE was being represented as: "char", instead of "char[]". This patch fixes 1 and 2. It also updates numerous test reference output files. * include/abg-ir.h (array_type_def::is_infinite): Fix indentation. * src/abg-ir.cc (qualified_type_def::build_name): An empty set of sub-ranges for a vector is represented by "[]".

Support naming typedef and use them to speed up type canonicalization
There is a common C idiom in which an anonymous struct is named using
a typedef:
typedef struct {int member;} anonymous_struct_type;
The typedef name "anonymous_struct_type" becomes the name of the
otherwise anonymous struct. That is what a naming typedef is.
So, the nice thing about naming typedefs is that an anonymous class
type suddenly becomes non anymous. So that type becomes eligible to
the ODR-based optimization during type canonicalization. That speeds
up type canonicalization, at least for 'abidw'.
This patch represents naming typedefs for class_decl types in the
internal representation. The patch also changes the meaning of an
anonymous class. Whenever such a class becomes named by a typedef,
the class is not considered anonymous anymore, at least for the
purpose of type canonicalization.

Implement de-duplication for types and decls at DWARF loading time
Many types and decls are redefined in every translation unit that make
up an ELF binary. This patch detects that a DIE represents a type or
decl that has already been defined in the current corpus and so will
not create a new internal representation for it.
The patch defines facilities to build the pretty representation of a
type or decl. It's by looking at the pretty representation of a DIE
that the patch detects that a different DIE has already defined the
same type or decl.
The patch also fixes detection of the const-ness of member functions
as there were many cases where const member functions were not
recognized as const. This fix makes it so that the pretty
representation of the DIE of said member functions match the pretty
representation of their internal representation, as far as the
const-ness is concerned.
One bit of infrastructure change that is used by the const-ness fix is
that method_type now carries const-ness. So a method_decl that has a
const method_type is going to be const itself.

pointer here.

Setup per-corpus type maps indexed by type names
This patch creates per-corpus maps that associate, for a certain kind
of type, the fully qualified name of the type to the type.
So there is a map for class_decl, one for enum_type_decl, one for
type_decl, etc.
These maps are populated when a new type is added to its scope.
The patch defines overloads of the function
maybe_update_types_lookup_map() that update the right map, depending
on the kind of type we are looking at.
Note that there also is a map in each class that associates a
signature string to a member functions. This is so that member
functions of a given class can be looked up by signature.
This is so that looking up a type becomes now much faster than having
to walk all the translation units of a corpus to find one.
Note that this patch is specifically part of the series of patches
that implements types and declarations de-duplication while reading
DWARF information.
The patch might slightly change the output of abi serialization or
comparison so it needs some adjustments of some test reference files.
That adjustment is not done here. Rather, it's done at once in
another patch of the set.
* include/abg-corpus.h (corpus::priv_): Make this public so that
functions from outside of the class can access it. These
functions are meant to be used only by code that is *inside*
libabigail.so, though.

Allow pretty printing function decls for internal purposes
It appears that function_decl::get_pretty_representation doesn't make the difference between internal and non-internal purposes. This patch fixes that by making the helper get_pretty_representation_of_declarator() take an "internal" flag and calls that. * include/abg-ir.h (function_decl::get_pretty_representation_of_declarator): Take an "internal" flag. * src/abg-ir.cc (function_decl::get_pretty_representation_of_declarator): Take an "internal" flag.

Support union types
This patch makes Libabigail understand C and C++ union types. It
defines a new class abigail::ir::union_decl to represent the
declaration of a union type. It also defines a new type
abigail::comparison::union_diff to represent the changes between two
union types. The patch then adds facilities to read union types from
DWARF and abixml and also to write union types into the abixml format.
As union types and class types have a lot in common, the patch tries
very hard to share code between the abigail::ir::class_decl and
abigail::ir::union_decl. To do so, a new class
abigail::ir::class_or_union is created. It's the base class for both
abigai::ir::class_decl and abigail::ir::union_decl. Its data members
and methods represent the set of data and behaviour that are common to
classes and unions. A lot of code and data that were initially in
abigail::ir::class_decl got moved into the new
abigail::ir::class_or_union class.
Similary, the patch creates a new class
abigail::comparison::class_or_union_diff that is a base class for both
the existing class abigail::comparison::class_diff and the newly
created class abigail::comparison::union_diff. The new class
abigail::comparison::class_or_union_diff contains data and behaviour
that are common to both union_diff and class_diff and that were
previously in class_diff.
The rest of the patch is mostly adjustment so that code that was
supposed to work with class class_decl only can now work with class
class_or_union when it makes sense. Similarly for class_diff and
class_or_union_diff.
The patch adds regression tests into the test suite and adjust many
existing tests involving binaries that contain union types; the
reference output of those tests now take union types into account.

Prevent infinite loops while comparing two function_type
While comparing two function types a given sub-type can itself have a

Drop suppressed ABI artifacts from the IR
This patch allows dropping suppressed ABI artifacts from the in-memory
internal representation right during the DWARF or abixml reading.
In practise, this means that abidw and abilint now have a
--suppressions options to give them suppression specifications. If a
suppression specification that has the "drop" property matches an ABI
artifact (type, function or variable) then that artifact is dropped
from the internal representation. This also applies to abidiff.
Note that now, by default, ABI artifacts (types) that are suppressed
due to the --headers-dir{1,2} option of abidiff are now also dropped
from the IR as well. Incidentally, abidw and abilint tools now have a
--header-dir option too.
* doc/manuals/abidw.rst: Document the new --suppressions and
--headers-dir options off the abidw tool.

Cleanup is_class and is_compatible_with_class_type
There was two overloads of is_class, one for types and one for decls. Now that we have type_or_decl_base which is a common base type for both, having just one is_class function that takes a type_or_decl_base is more compact and easier to maintain. This patch does that. It also cleans up the declaration of the is_compatible_with_class_type function. * include/abg-fwd.h (is_class): Remove the overloads that take a decl_base or a type_base.

Better recognize qualified void type
This fixes Bug 20329 - DW_TAG_const_type with no DW_AT_type not recognized as "const void". It appears that GCC sometimes emits "const void" types by emitting a const type DIE with no type attribute. The DWARF reader didn't recognize that construct as a qualified void type. This patch teaches the DWARF reader to recognize that construct. It also appears that "const void" and "void" are equivalent and can be emitted interchangeably by compilers (Intel and GCC) in their debug info. That can lead to spurious ABI change reports saying that a type "const void" was changed into a "void" type. This patch transforms an occurrence of "const void" type into a "void" type in the internal representation when reading DWARF. This does away with the spurious change that appears when comparing selected binaries emitted with the intel against binaries emitted with GCC. * include/abg-ir.h (environment::is_void_type): Declare new member function. * src/abg-ir.cc (environment::is_void_type): Define new member function. * src/abg-dwarf-reader.cc (maybe_strip_qualification): Strip const qualifier from const void. * tests/data/test-diff-filter/test34-libjemalloc.so.2-gcc-6.1.0: New test input. * tests/data/test-diff-filter/test34-libjemalloc.so.2-intel-16.0.3: Likewise. * tests/data/test-diff-filter/test34-report-0.txt: New reference output. * tests/data/Makefile.am: Add the new files above to the source distribution. * tests/test-diff-filter.cc (in_out_specs): Compare the two new binaries above. * tests/data/test-diff-filter/test30-pr18904-rvalueref-report0.txt: Adjust. * tests/data/test-diff-filter/test30-pr18904-rvalueref-report1.txt: Adjust. * tests/data/test-diff-pkg/tbb-4.1-9.20130314.fc22.x86_64--tbb-4.3-3.20141204.fc23.x86_64-report-0.txt: Adjust. * tests/data/test-diff-pkg/tbb-4.1-9.20130314.fc22.x86_64--tbb-4.3-3.20141204.fc23.x86_64-report-1.txt: Adjust. * tests/data/test-read-dwarf/test1.abi: Adjust. * tests/data/test-read-dwarf/test10-pr18818-gcc.so.abi: Adjust. * tests/data/test-read-dwarf/test11-pr18828.so.abi: Adjust. * tests/data/test-read-dwarf/test12-pr18844.so.abi: Adjust. * tests/data/test-read-dwarf/test13-pr18894.so.abi: Adjust. * tests/data/test-read-dwarf/test14-pr18893.so.abi: Adjust. * tests/data/test-read-dwarf/test15-pr18892.so.abi: Adjust. * tests/data/test-read-dwarf/test16-pr18904.so.abi: Adjust. * tests/data/test-read-dwarf/test17-pr19027.so.abi: Adjust. * tests/data/test-read-dwarf/test18-pr19037-libvtkRenderingLIC-6.1.so.abi: Adjust. * tests/data/test-read-dwarf/test19-pr19023-libtcmalloc_and_profiler.so.abi: Adjust. * tests/data/test-read-dwarf/test20-pr19025-libvtkParallelCore-6.1.so.abi: Adjust. * tests/data/test-read-dwarf/test21-pr19092.so.abi: Adjust. * tests/data/test-read-dwarf/test22-pr19097-libstdc++.so.6.0.17.so.abi: Adjust. * tests/data/test-read-dwarf/test9-pr18818-clang.so.abi: Adjust.

Bug 20180 - Support system-wide suppression specifications
This patch adds support for loading system and user level suppression specifications for libabigail tools. At launch time, relevant libabigail tools (abidiff, abipkgdiff fedabipkgdiff for now) read the default system suppression specification file, if it's present, from a file which path is the value of the environment variable LIBABIGAIL_DEFAULT_SYSTEM_SUPPRESSION_FILE, if set, or from the file $libdir/libabigail/default.abignore. Then it reads the user system suppression specification file, if it's present, from a file which path is the value of the environment variable LIBABIGAIL_DEFAULT_USER_SUPPRESSION_FILE, if set, or from the file $HOME/.abignore. The content of the user system suppression file is merged with the content of default system suppression file. That content is also merged with the content of the suppression specification files that might be provided by the --suppressions command line option of the invoked tools. The resulting set of all these suppression specifications is thus used to filter the ABI change reports that are emitted. abidiff, abipkgdiff and abipkgdiff gain a --no-default-suppression option to avoid loading any of these default suppression specification files. The patch also installs a default.abignore file into $(pkglibdir). Note that on x86_64, that directory is /usr/lib64/libabigail. Now we just need to think about the content of that default.abignore file. * doc/manuals/abidiff.rst: Document the default suppression scheme, its interaction with the --supprs option and the new --no-default option. * doc/manuals/abipkgdiff.rst: Likewise. * doc/manuals/fedabipkgdiff.rst: Likewise. * configure.ac: Generate the tests/runtestdefaultsupprs.py file from the new tests/runtestdefaultsupprs.py.in template. * default.abignore: New file. * Makefile.am: Add it to source distribution. * src/Makefile.am: Define the ABIGAIL_ROOT_SYSTEM_LIBDIR preprocessor macro that is set the value of the $libdir autotools macro. * include/abg-tools-utils.h: Update copyright years.

Make abi{pkg}diff filter out changes about private types
This is to address the following enhancement requests:
#19588 - Add a --headers-dir1 and --headers-dir2 option to abidiff
#19948 - Add --devel-pkg1 and --devel-pkg2 options to abipkgdiff
When the user specifies where to find header files for two binaries
(or packages) being compared, this patch generates a type suppression
specification that filters out change reports about types that are
defined in files that are not in the set of header files specified.
The type suppression specification also suppresses change reports
about changed/added/removed virtual member functions which enclosing
class type matches the type suppression specification.
There is a corner case that the patch handles too, and that is
exhibited by the accompanying test case for abidiff. There can be a
class defined by DWARF as having no source location and as being a
pure declaration. This can be a class declaration that has inline
virtual members only, and one or several non-defined virtual methods
too. When that declaration is included in a source file, GCC
generates debug info that describes that class as being a
declaration-only class with no source declaration. This patch
considers such a class as being non defined; you know, like a true
opaque type. So it's considered being not defined in any public
header file. Changes to this kind of class are thus filtered out.

Optimize out some shared_ptr use
Profiling showed that getting the pointed-to type of a pointer type is on the hot spot when comparing corpora with a lot of entry points with a lot of pointer types reachable from the entry points of the corpora. So avoid handling the shared_ptr to the pointed-to type for that case can save us a few CPU cycles in a noticeable way. This patch does this by creating a new pointer_type_def::get_naked_pointed_to_type() (that returns a naked pointer) to supplement the classic pointer_type_def::get_pointer_to_type() function, and uses that in a code spot that profiling revealed to be a critical path. * include/abg-ir.h (pointer_type_def::get_naked_pointed_to_type): Declare new member function. * src/abg-ir.cc (pointer_type_def::priv::naked_pointed_to_type_): New data member.

Plug leak of diffs of member variables of class type
On certain work loads, cycles in the tree of diffs of member variables
can appear. This because:
1/ each diff tree nodes holds a reference on each of its children
nodes
2/ each var_diff tree node holds a reference on the diff tree node
representing its type changes.
There can thus be reference cycles in involving diff the tree --> child
node relationship and the var_diff tree --> type diff tree
relationship.
This patch fixes the issue be make sure that a diff tree node does not
hold a reference on its children nodes. That is, rather than having a
vector of shared pointers to its children diff nodes, it has a vector
of naked pointers to those. The patch goes further by making sure
that a var_diff node does not hold a reference to its type diff node
either. It holds a weak pointer to the type diff node, rather than a
shared pointer.
The patch should be followed by a patch make sure that all kinds of
diff nodes follow this pattern; that is, if a diff node needs to carry
a sub-type diff node, it should do so by either using a naked pointer
to the sub-type diff node, or a weak pointer.
For now, the patch fixes the leaks reported by running all the tests
of the suite under Valgrind.

Plug leak of shared private data of class_diff type
Some time ago, a memory optimization was put in place to reduce the
memory usage of the IR used to represent the result of a comparison
between two corpora.
The principle of that optimization was to share the data of the
class_diff::priv member among instances of class_diff that are in the
same class of equivalence.
In practice, the class_diff::priv member of an instance that has a non
empty class of equivalence was set to the class_diff::priv of its
canonical type.
Because clas_diff::priv is a shared pointer, setting it to the
class_diff::priv of another instance was creating cycles in the graph
of class_diff, sometimes. And those cycles lead to memory leaks as
the reference count of shared pointers to class_diff would not go down
to zero anymore.
This patch fixes the problem of those cycles by not setting the
class_diff::priv data member. Rather, when a class_diff is part of a
non-empty class of equivalence, its class_diff::priv is left nil. A
new class_diff::get_priv() accessor is provided; it returns the shared
class_diff::priv of the canonical type when the current
class_diff::priv is nil; otherwise it just returns the current
class_diff::priv.
* include/abg-comparison.h (class_diff::get_priv): Declare new
member function.
(class_diff::get_priv): Define new member function.
(class_diff::{chain_into_hierarchy, base_changes, deleted_bases,

member_fn_tmpls_changes, member_class_tmpls_changes,

class_diff::priv directly, use the new class_diff::get_priv.

Remove circular ref from class_decl::priv::definition_of_declaration
It appears that there are cases where the data member class_decl::priv::definition_of_declaration_ can point to the current instance of class_decl, leading to a circular reference and thus a leak because the reference count of the current instance of class_decl will never reach zero. This patch fixes that by making class_decl::priv::definition_of_declaration_ be a weak pointer, rather than a smart pointer. * include/abg-ir.cc (class_decl::get_definition_of_declaration): Return a shared pointer, rather than a reference to a shared pointer. * src/abg-ir.cc (class_decl::priv::definition_of_declaration_): Make this be a weak pointer.

Implement a [suppress_file] suppression directive
abidiff, abipkgdiff and abicompat now recognize a [suppress_file]
directive in suppression specifications. That directive instructs the
tool to avoid loading some binaries altogether.
This is the first directive that won't act on the result of the
comparison of two binaries. It actually acts earlier and prevents the
tool from loading some binaries altogether.
The directive looks like:
[suppress_file]
# Don't load any library named lib_private*.so
file_name_regexp = lib_private.*\\.so
This prevents the tool from loading (and thus comparing) any library
which name matches the pattern "lib_private*.so".
[suppress_file]
# Only load libraries name lib_public*.so
file_name_not_regexp = lib_public.*\\.so
This instructs the tool to only load (and compare) files which name
match the pattern "lib_public*.so".

'suppress_file' directive.

Bug 20015 - support file_name_not_regexp and soname_not_regexp in suppr specs
The supression directives suppress_type, suppress_function and
suppress_variable support the two properties below, among others:
file_name_regexp = <some-regexp>
soname_regexp = <some-regexp>
When the regular expression matches either the file name or the
soname, then the suppression directive is activated.
This patch adds the support for these two additional properties for
these suppression directives:
file_name_not_regexp = <some-regexp>
soname_not_regexp = <some-regexp>
These activate the current suppression directive if the regular
expression does *NOT* match the file name or soname.
This is very helpful to express change report suppressions like:
"suppress all ABI change reports for all libraries but those with
file names (or sonames) with the pattern libfoobar.*"

Bug 19961 - Distinguish between PI executable and shared library
In the ELF format, Position Independent Executables (aka PIE) and shared libraries are marked as being of type ET_DYN. So just looking at the type of the ELF file is not enough to discriminate a position independent executable from a shared library. And this is the problem. Libabigail just looks at the type of the ELF file to discriminate PIE binaries from shared libraries binaries. So it treats both kinds of binaries as being shared libraries. When we run abipkgdiff with the --dso-only option, the tool considers both PIEs and shared libraries, even though the intent of the --dso-only option is have the tool consider shared libraries only. With this patch, we introduce a new enumerator ELF_TYPE_PI_EXEC (to the elf_type enum) for PIE binaries. From now on, a file will be properly recognized as being of the ELF_TYPE_DSO kind only if it is a shared library. * include/abg-dwarf-reader.h (elf_type): Add new enumerator ELF_TYPE_PI_EXEC. * src/abg-dwarf-reader.cc (lookup_data_tag_from_dynamic_segment): New function for data tag lookup in dynamic segment of an elf (elf_file_type): Return ELF_TYPE_PI_EXEC file type for a PI executable.

Implement string interning for Libabigail
This patch implements string interning optimization. One can read about the principles of this optimization at https://en.wikipedia.org/wiki/String_interning. The patch introduces an abigail::interned_string type, as well as an abigail::interned_string_pool type. Each environment type owns a string pool and strings are interned in that pool for all types and decls of that environments. The interned_string has methods to interact seemingly with std::string including a hashing function. Of course hashing and comparing interned_string is faster than for std::string. To enable ABI artifacts to intern strings, each constructor of ABI artifacts now takes the environment it's constructed in as parameter. From the environment, it can thus use the interned string pool. The patch then changes declaration names to be of type interned_string, and performs the necessary adjustments.

Add missing inequality operators for ABI artifacts
Some ABI artifact declared in the internal representation don't have
inequality operator (!=) declared. I thought relying on the !=
operator provided by std::rel_ops would be enough, but it's not.
Sometimes, especially for smart pointers to ABI artifacts we do not
want the != operator of shared_ptr to be picked by argument dependent
lookup. Rather, we want the deep operator!= to be picked up. In certain
cases, this was causing subtle spurious change comparison reports.
This patch thus systematically declares (and defines) operator!=
whenever operator== is declared.

Bug 19658 - Type canonicalization slow for the 2nd binary loaded
When loading two binaries (e.g, when the library is used by abidiff),
and when the second one does have deep types (e.g, classes with
recursively deep hierarchies) with lots of duplicated types in lots of
translation units, canonicalizing the types of the second binaries can
take a *lot* of time, given the quadratic nature of the structural
type comparisons that take place and the cheer number of those type
comparisons (because of the duplication).
There is already an optimization based on the One Definition Rule in
the canonicalization code. That optimization avoids structural
comparison of types of the same corpus which have the same name. But
then, this optimization only works on types of the first corpus.
As soon as we are loading a second corpus, all types being
canonicalized are coming from a corpus that is different from the
first corpus, by definition. So a structural comparison is taking
place for *all* those types.
The patch extends the existing optimization to make it work on the
second corpus being loaded. Once a type from the second corpus is
canonicalized, the canonical type is cached inside the corpus. Then,
later, when a type with the same name has to be canonicalized, the
system looks inside the cache of that corpus to see if there is a
canonicalized type the same name.
I tested the patch on this command:
abipkgdiff --d1 nss-debuginfo-3.19.1-8.el6_7.i686.rpm \
--d2 nss-debuginfo-3.21.0-0.1.el6_7.i686.rpm \
nss-3.19.1-8.el6_7.i686.rpm \
nss-3.21.0-0.1.el6_7.i686.rpm
I whitnessed a x10 speedup, at least.
On binaries that don't have a lot of duplicated deep types, the patch
doesn't have any noticeable effect. At lesat It doesn't slow things
down in that case.

Bug 19638 - DWARF reader fails to link clone function to its declaration
There are three mains issues that cause the reported problem. Let's look at them closely. Suppose there is a DIE of a member function Klass::clone_of_foo, which is a clone of the DIE of the function Klass_foo, which is the concrete instance of the DIE of the declaration of Klass::foo. When libabigail's DWARF reader sees the DIE for Klass::clone_of_foo, it fails to get the context of the declaration of Klass::clone_of_foo -- which is Klass::foo. So, in the model built by libabigail, the symbol of Klass::clone_of_foo never gets associated to Klass::foo. It thus looks like Klass::clone is never defined. It also looks like that symbol is unreferenced. From there, a number of bad things happen. This is the first root cause of the reported problem. I call it issue 1/. 2/ While looking at this, I noticed that libabigail uses the underlying symbol name of a given function as the linkage name of that function, rather than using the value of the DW_AT_linkage_name DWARF property. This usually works, until the the function has a symbol which has several aliases. In that case, depending on the symbol alias that is used, a given function can have different linkage names. This causes problems later at comparison time. This is issue 2/. 3/ I also noticed that in the libabigail model, even if type Klass does have all its member functions (including Klass::foo) defined in in a particular translation unit TU1 , the same Klass in another translation unit TU2 might not have that Klass::foo defined, just because that function is not used in TU2. So after type canonicalization, if the version of Klass that is kept is the one from TU2, we end up with a type Klass *NOT* having Klass::foo defined. Sometimes, it's just that one member function in the canonical type doesn't have any underlying symbol, whereas the same member function in another type of the same class of equivalence as the canonical type does have that an underlying symbol. This is issue 3/. To address issue 1/ the patch fixes build_ir_node_from_die, in the case where a DW_TAG_subprogram DIE is being handled. It fixes the case of finding the root interface of the clone of a function definition. The patch also fixes a bug in build_function_decl that prevents it to update the linkage name of a function, *if* that function already had one. This was preventing build_function_decl to adjust the linkage name of a function which is a clone of an original function which already had a non-empty linkage name. To address 2/ the patch makes function_decl::get_id return the linkage name of the function, *if* it exists (rather than primarily returning the ID of the underlying symbol). To address 3/ the patch implements the copying of member functions or underlying function symbols missing from the canonical type -- but otherwise present in the type that has just been canonicalized. * include/abg-ir.h (decl_base::set_linkage_name): Make this member function virtual.

Fix synthesizing of pointer type
Libabigail fails to to synthesize a non-existing pointer type to an existing type. This makes abicompat fail in weak mode when trying to detect changes to a function type where the parameter is a pointer to a structure which changed. In the application, the function is invoked and a pointer to the structure is passed to it. It appears that the type of structure is defined in the debug info of the application, but not the pointer to that structure. So abicompat needs to synthesize that pointer to struct in order to synthesize the type of the function, and so, compare it to the type of the function coming from the library.

Bug 19141 - Libabigail doesn't support common ELF symbols
Libabigail's internal representation of elf symbols fails to account
for common symbols in relocatable files. There can be several common
symbols of the same name (defined in a section of SHN_COMMON kind).
In that case, Libabigail wrongly considers these multiple instances of
the same common symbol as being alias, and that breaks some
basic assumptions about aliases. Oops.
This patch adds support for the common symbols (and the fact that
relocatable files can have several instances of the same common
symbol) and amends the ELF reader to make it properly represent those.

[PERF] Turn some pimpl pointers into naked pointers
The private data pointers of libabigail IR types are usually managed
using shared_ptr. But performance profiling has shown that
de-referencing some of these private data shared_ptr can have a
noticeable performance impact. This is because de-referencing
shared_ptr involves some locking that show up on some performance
profile.
So, for decl_base, type_base, and function_decl, this patch replaces
the private data shared pointers by naked pointers. This speeds up
the access to private data members, especially during comparison of
class pointer, reference and function types. And that has a
noticeable impact when libabigail handles huge binaries with lots of
functions an type, like r300_dri.so.

Bug 19126 - abidw segv on a dwz compressed version of r300_dri.so
Suppose a declaration D (which locus is in a file F) is imported at an
offset offset of O1 into a compilation unit C1 and at an offset O2
(using DW_TAG_imported_unit) into a compilation unit C2.
When the DWARF reader creates the ABI artifact for D in O1, its
location is encoded by a location manager that is handled by C1.
At O2 (in C2) the ABI artifact for D (created at O1, in C1) is
re-used. But then, to decode the location of D, the DWARF reader
wrongly uses the location manager that is handled by C2. It should
use the location manager of C1, because that is the one used to encode
the location of D.
It picks the wrong location manager because it picks the wrong
translation unit for D. Right now, the translation unit for a given
declaration is the "current" translation unit at the moment the DIE
was being inspected. And that is wrong when imported type units kick
in.
1/ More generally, each ABI artifact should be associated with its
translation unit, which is the current translation unit when the
artifact was created. As there is just one copy of D, its translation
unit should always be the same.
2/ Also, the location should ensure that about the location manager used
to encode it is the same one used to decode it, so that this kind of
bug cannot arise.
This patch fixes the issue by doing 1/ and 2/. The r300_dri.so test
case on which is was failing is not added to the test suite because
it's too big. It was taking more than 55 minutes to have complete
abidw --abidiff complete on that binary, on my machine. So I am going

Bug 19336 - Better handle redundantly qualified reference types
Sometimes we can see const references in DWARF. But then, a reference
is always const, so that qualified reference is redundant.
Furthermore, having that construct make its way into the internal
representation can cause awkward diagnostics.
The DWARF reader was thus eliding such redundant qualifiers in the
function "maybe_strip_qualification". It was doing so by stripping
the qualifier from the qualified type. So const reference, for
instance, becomes a (non-qualified) reference. In that case, we are
turning a qualified type into a non-qualified one.
But as the accompanying problem report suggests, this can cause issues
during the DWARF parsing. This is because a given Debug Information
Entry (DIE) of qualified type kind can be referenced elsewhere, by
another type. That other type expects that DIE to be a qualified
type. And libabigail's DWARF reader code enforces that. So the
internal representation of a type resulting from a qualified type DIE
must be a qualified type itself.
So the way the function "maybe_strip_qualification" was doing the
redundancy elision was wrong. This patch fixes that by keeping the
type qualified, but introducing a "no-op" qualifier. Actually, the IR
already has that "no-op" qualifier: abigail::ir::qualified_type_def::CV_NONE.
So now "maybe_strip_qualification" just turns the CV_CONST qualifier
into a CV_NONE one when the former is redundant.
Now that the libabigail type system actually *has* types qualified
with this no-op qualifier, we need to handle things like printing the
name of such qualified types. When we are printing the name of the
type for internal reasons (i.e, for type canonicalization purposes) we
need to make a difference between the name of a no-op qualified type
and the name of the underlying type of the qualified type, otherwise,
the canonicalizer wrongly considers the two types as being equal. But
then when we are printing the name of the no-op qualified type for
diagnostics reasons, then the name is the same as the name of its
underlying unqualified type.

the qualified type. Rather, just turn the redundant const
qualifier into a no-op one.

Do not forget to peel qualified type off when peeling types
When peeling off typedefs, references and pointers to see if a type is made of a class type, we forget to peel qualified types off.

Bug 19173 - Abidiff doesn't detect symbol size change in library
It appears that libabigail does not represent the size of ELF symbols,
so it doesn't detect when a symbol size changes without impacting the
size of the type of said symbol, as described by debug info.
It appears that Address Sanitizer as implemented by Clang does change
the size of variable symbols when it instruments those variables. And
of course, the size of type of said symbols (as described by debug
information) remains unchanged.
This patch makes Libabigail become aware of symbol sizes, especially
for variables. Symbol sizes for functions are ignored for now,
because a change in a function symbol size is not an ABI change.
The patch makes libabigail detect and report symbol size changes for
variables, but looking at the ELF information, independently from the
debug information.
The patch adjusts the existing tests and adds a new test using the
binaries that were filed in the bug report.

Bug 19139 - DWARF reader doesn't handle garbage in function names
In this bug, the DWARF debug info of the binary (generated by Intel's
ICC compiler) has interesting constructs like:
[ 6b5a0] subprogram
decl_line (data2) 787
decl_column (data1) 15
decl_file (data1) 46
declaration (flag)
accessibility (data1) public (1)
type (ref4) [ 6b56a]
prototyped (flag)
name (string) "ldiv"
MIPS_linkage_name (string) "ldiv"
[ 6b5b6] formal_parameter
type (ref4) [ 5f2aa]
name (string) "$Ë2"
[ 6b5bf] formal_parameter
type (ref4) [ 5f2aa]
name (string) "$Ë3"
Note the strings that make up the name of the formal parameters of the
function, near the end:
[ 6b5b6] formal_parameter
type (ref4) [ 5f2aa]
name (string) "$Ë2"
[ 6b5bf] formal_parameter
type (ref4) [ 5f2aa]
name (string) "$Ë3"
The strings "$Ë2" and $Ë3" (which are the names of the
parameters of the function) are garbage.
Libabigail's DWARF reader naively uses those strings as names for the
function parameters, in the type of the function.
Then, the abixml writer emits an XML document, with these strings as
property values, representing the name of the type of the function.
And of course, the XML later chokes when it tries to read that XML
document, saying that the property is not valid UTF-8.
This patch addresses the issue by dropping those garbage names on the
floor, for function type names. In that context, any string that is
not made of ASCII characters is considered as being garbage, for now.
The patch, in the abixml writer, also escapes function parameters
names so that they don't contain characters that are not allowed in
XML. The abixml reader already handles the un-escaping of the names
it reads, so I think there is nothing to do there.
Ultimately, I guess I should get the unicode value of the characters
of that string, encode the string into UTF-8 and use the result as the
name for the parameter. That would mean using UTF-8 strings for
function parameter names, and, for all declarations names. But that
is too much for worfk too little gain for now. The great majority of
the binaries we are dealing with are still using ASCII for declaration
names.
The patch also introduces a new test harness that runs "abidw
--abidiff" on a bunch of input binaries. This harness runs over the
binaries that were submitted in this bug report.
* include/abg-tools-utils.h (string_is_ascii): Declare new
function ...
* src/abg-tools-utils.cc (string_is_ascii): ... and define it.
* src/abg-writer.cc (write_function_type): Escape forbidden XML

Support updating a class in the abixml reader
In DWARF, the same class declaration can be present several times but
with different "views", that is, it can be present in a first
translation unit, but without any member type; then in a subsequent
translation unit, its member types are defined. In another, it'll be
completely defined, with all its data members and base classes. The
DWARF reader knows how to amend the class to add new members to it, as
they show up in the debug information.
This patch adds the same functionality to the abixml reader. The
writer has already started to write class declarations with different
"views" too, since it's started to avoid duplicating full class
definitions in every translation unit that uses them.
Without this patch, abixml misses some class members, and that is a
bug.

find_member_type, find_data_member}): Declare new member functions ..

Accelerate a slow path in hash_type_or_decl()
Profiling shows that hash_type_or_decl() is very slow when hashing function parameters and base class specifications. This is because in those two cases we use the slow recursive hashing algorithm to hash types, rather than using the faster one based on using the pointer values of canonical types when possible.

Implement fast type lookup in a corpus
Profiling has shown that on libraries with a lot of class types
declarations (more than 10K types), the phase of resolving those
declarations to their definition was a hot spot. The lookup of the
type definition inside the entire corpus was the bottleneck.
This patch removes (or loosen) that bottleneck by doing away with the
graph-walking-based type lookup algorithm that was used. Rather, maps
of name -> types are maintained by each scope, in each translation
unit. Those maps are updated each time a type is added to a scope.
And looking up a type amounts to a lookup in a map. Way faster.

becomes a definition, update the name -> type map maintained in
the scope of the class.

name -> types that is now maintained in the translation unit.
This is way faster than the previous walking algorithm.
* src/abg-dwarf-reader.cc (build_translation_unit_and_add_to_ir):

Handle aliased function decls when comparing decls in general
When comparing two declarations, we look at their linkage name. When the linkage names are different, then we infer that the two decls are different. But then, for *function* decls, it can happen that two different linkage names are actually for different symbols that do alias; the (ELF) symbols are different but they have the same address; so they point to the same "thing". The two functions are not different, then. And we were not supporting this last case of diffent linkage names that are aliases of each other. This patch adds support for that. * include/abg-ir.h (is_function_decl): Add a const to the reference parameter, making it comply with the definition. * src/abg-ir.cc (equals): In the overload for decl_base, when the two linkage names are different, consider the case of the decls being aliased functions.

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.

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.

Bug 19023 - Type canonicalization is sensitive to struct-ness
In some debug info of some shared library, the same type can be present as a struct in some translation units, and as a class in others.

Bug 19037 - Make ABI corpus support several functions with same symbol
It turns out that, in DWARF, there can be function template
instantiations foo<int>(int) and foo<TypedefOfInt>(TypedefOfInt) which
have the same symbol name, if TypedefOfInt is a typedef of int.
An ABI corpus retains only one function declaration per symbol
name. So in the example of the bug the input DWARF has the two
instantiations, but libabigail is just keeping one of the two; so the
abixml only has one of the two template instantiations.
This patch changes the ABI corpus model so that it represents the fact
that there can be several function declarations for a given symbol.
The patch then adjust the comparison engine to make it know about this
new model.
* include/abg-corpus.h
(corpus::exported_decls_builder::str_{fn,var}_ptr_map_type):
Remove these typedefs from here as they only used internally in
abg-corpus.cc. So we move them there instead.
* src/abg-corpus.cc (str_fn_ptrs_map_type): New typedef.
(str_var_ptr_map_type): Moved the typedef that was in
corpus::exported_decls_builder here.
(corpus::exported_decls_builder::id_fns_map_): Rename the fns_
data member into this. Make it have a str_fn_ptrs_map_type as a
type.
(corpus::exported_decls_builder::id_fns_map): Renamed the
fns_map() accessor into this one.
(corpus::exported_decls_builder::{fn_id_is_in_id_fns_map,
fn_is_in_fns}): New member functions.
(corpus::exported_decls_builder::fn_is_in_id_fns_map): Rename
fn_is_in_map into this.
(corpus::exported_decls_builder::add_fn_to_id_fns_map): Rename
add_fn_to_map into this.
(corpus::exported_decls_builder::add_fn_to_exported): Adjust.
(corpus::exported_decls_builder::maybe_add_fn_to_exported_fns):
Adjust.
* src/abg-comparison.cc (function_decl_diff::report): Emit reports
about function name changes (for a given function ID) only if
there are sub-type changes to be reported for the function. In
that case, do not forget to emit the sub-type changes after the
name changes have been reported.
(corpus_diff::priv::ensure_lookup_tables_populated): Several
functions of the same ID can be removed or added from/to the
corpus.
* tests/data/test-read-dwarf/test18-pr19037-libvtkRenderingLIC-6.1.so:
New test input binary.
* tests/data/test-read-dwarf/test18-pr19037-libvtkRenderingLIC-6.1.so.abi:
New test output reference.
* tests/data/Makefile.am: Add the new test materials to the source
distribution.
* tests/test-read-dwarf.cc (in_out_specs): Adjust to add the new
test inputs above.

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.

Late canonicalize all types that reference classes when reading DWARF
Until now, the DWARF reader would late canonicalize typedefs to classes, as well as classes. That is not enough. Let's also late-canonicalize pointers, references and array of classes too. This is because classes that might not be finished yet might be referenced by those types, and so we want to wait until they are finished before we canonicalize them. * include/abg-fwd.h (peel_array_type): Declare new function. * src/abg-ir.cc (peel_array_type): Define it. (peel_typedef_pointer_or_reference_type): Peel arrays too, to get the type of its element. * src/abg-dwarf-reader.cc (maybe_canonicalize_type): If a pointer, reference, array or typedef references a class, then do late-canonicalize this type.
