Fix interaction of --redundant and --leaf-changes-only options.
The --redundant (meaning show-redundant-changes) option is supposed to be implied by --leaf-changes-only and this is currently implemented by making diff_context's --leaf-changes-only setter also duplicate the behaviour of its --redundant setter. In both abidiff and abipkgdiff, the diff_context setters are called unconditionally, but the relative order of the calls for these two options is different in each case, resulting in two different issues. In abidiff, the --redundant setter is called second, undoing the intended side-effect of any --leaf-changes-only flag. So --redundant is not actually turned on in --leaf-changes-only mode unless requested explicitly. In abipkgdiff, the leaf-changes-only setter is called second, undoing (in non-leaf mode) the effect of any --redundant flag. So --redundant has no effect in default reporting mode. The fix is move to move the "--leaf-changes-only implies --redundant" logic from the setter to the set_diff_context_from_opts functions. This patch also documents the implied behaviour in the usage strings. * src/abg-comparison.cc (diff_context::show_leaf_changes_only): Remove "--leaf-changes-only implies --redundant" logic. * tools/abidiff.cc (display_usage): Mention that --leaf-changes-only implies --redundant. (set_diff_context_from_opts): Make --leaf-changes-only imply --redundant; document this behaviour in a comment. * tools/abipkgdiff.cc: Ditto. * tests/data/Makefile.am: Add new test case files. * tests/data/test-abidiff-exit/test-leaf3-report.txt: Add new test case, to show --leaf-changes-only implies --redundant. * tests/data/test-abidiff-exit/test-leaf3-v0.c: Ditto. * tests/data/test-abidiff-exit/test-leaf3-v0.o: Ditto. * tests/data/test-abidiff-exit/test-leaf3-v1.c: Ditto. * tests/data/test-abidiff-exit/test-leaf3-v1.o: Ditto. * tests/test-abidiff-exit.cc: Run new test case. * tests/data/test-diff-pkg/libcdio-0.94-1.fc26.x86_64--libcdio-0.94-2.fc26.x86_64-report.1.txt: Update abipkgdiff report with --redundant output. * tests/data/test-diff-pkg/spice-server-0.12.4-19.el7.x86_64-0.12.8-1.el7.x86_64-report-1.txt: Ditto. * tests/data/test-diff-pkg/spice-server-0.12.4-19.el7.x86_64-0.12.8-1.el7.x86_64-report-2.txt: Ditto.

abidiff/kmidiff: do not default-suppress added symbols
kmidiff and abidiff do filter out added symbols (vars, functions and symbols without debug info) by default when dealing with kernel binaries. The reason for this is that the ABI could be considered compatible and not broken when adding symbols. In practice, this is confusing as there is no possibility for a symmetric comparison (i.e. a deleted function when comparing left to right is an added function when comparing right to left). Furthermore, there is no option available to actually report these added symbols. I thought of adding an option to report added symbols, but in the end came to the conclusion that we should behave consistent across the various ways you can diff an ABI with abidiff and kmidiff and should not change default behaviour for a particular type of binary. Hence, remove the default behaviour of filtering out added symbols when comparing kernel binaries. To restore the current behaviour, the user needs to parametrize with the tools with --no-added-syms --no-unreferenced-symbols. Adjusted test cases accordingly and add a new test that covers the old behaviour new available with additional flags to abidiff. * tools/abidiff.cc (adjust_diff_context_for_kmidiff): Drop default suppression of added symbols. * tools/kmidiff.cc (set_diff_context): Likewise. * tests/data/test-diff-suppr/test46-PR25128-report-1.txt: Adjust test expectation. * tests/data/test-diff-suppr/test46-PR25128-report-2.txt: Add test case for abidiff with flag --no-added-syms. * tests/data/Makefile.am: add new testcase.

Bug 24690 - Support comparing non-reachable types of a binary
This patch adds the ability to compare all types of a binary,
including those types that are not reachable from global functions and
variables.
This implies that for types that are not reachable from public
interfaces, we want compare them against each others directly, without
first comparing global functions/variables and walking the graph of
reachable types from there.
The patch adds the --non-reachable-types option to abidiff and
abipkgdiff, instructing them to also compare types that are
non-reachable from global variables and functions.
Using that option, for instance, here is what the summary of
abipkgdiff now looks like, in the test case attached added by this
patch:
================ changes of 'libflatpak.so.0.10204.0'===============
Functions changes summary: 0 Removed, 0 Changed (16 filtered out), 16 Added functions
Variables changes summary: 0 Removed, 0 Changed, 0 Added variable
Unreachable types summary: 3 removed (2 filtered out), 1 changed (15 filtered out), 3 added (1 filtered out) types
You can see that there is a new summary line which starts with the
string: "Unreachable types summary:"
Then in the body of the report, those unreachable types are reported
separately.
In practise, we want to limit the unreachable types to compare
somehow, otherwise we'll end up comparing all the types of the types
of the binary and that can be huge. So we want to limit the
unreachable type analysis to types that are defined in public headers.
So, for abipkgdiff, one can limit the analysis of non-reachable types
to those defined in public headers by supplying the --devel{1,2}
options that specifies the development packages that contain said
public headers. For abidiff however, you'll want to use the
--headers-dir{1,2} options for that.
The patch comes with appropriate regression tests.

Add compatibility layer for C++11 mode
Introduce a compatibility layer for C++11 code by adding include/abg-cxx-compat.h. abg-cxx-compat defines a new namespace abg_compat and defines abg_compat::hash abg_compat::shared_ptr abg_compat::weak_ptr abg_compat::dynamic_pointer_cast abg_compat::static_pointer_cast abg_compat::unordered_map abg_compat::unordered_set based on definitions from std::tr1 (std=gnu++98) or std:: (std=gnu++11). I decided for introducing abg_compat:: rather than polluting abigail:: to allow an easier transition to C++11 at a later time and to not subtly break existing code. As the shared_ptr in C++11 defines shared_ptr::operator bool() explicit, some locations where a shared_ptr is assigned to boolean, needed to be adjusted to explicitly cast to bool. * include/abg-cxx-compat.h: new file introducing the abg_compat namespace to provide C++11 functionality from either std::tr1 or std:: * include/Makefile.am: Add the new abg-cxx-compat.h to source distribution. * include/abg-comparison.h: replace std::tr1 usage by abg_compat and adjust includes accordingly: likewise * include/abg-diff-utils.h: likewise * include/abg-fwd.h: likewise * include/abg-ini.h: likewise * include/abg-interned-str.h: likewise * include/abg-ir.h: likewise * include/abg-libxml-utils.h: likewise * include/abg-libzip-utils.h: likewise * include/abg-reporter.h: likewise * include/abg-sptr-utils.h: likewise * include/abg-suppression.h: likewise * include/abg-tools-utils.h: likewise * include/abg-workers.h: likewise * src/abg-comp-filter.cc: likewise * src/abg-comparison-priv.h: likewise * src/abg-corpus.cc: likewise * src/abg-dwarf-reader.cc: likewise * src/abg-hash.cc: likewise * src/abg-ir.cc: likewise * src/abg-reader.cc: likewise * src/abg-suppression.cc: likewise * src/abg-tools-utils.cc: likewise * src/abg-writer.cc: likewise * tests/test-diff-filter.cc: likewise * tests/test-diff-pkg.cc: likewise * tests/test-read-dwarf.cc: likewise * tests/test-read-write.cc: likewise * tests/test-types-stability.cc: likewise * tests/test-write-read-archive.cc: likewise * tools/abicompat.cc: likewise * tools/abidiff.cc: likewise * tools/abidw.cc: likewise * tools/abilint.cc: likewise * tools/abipkgdiff.cc: likewise Signed-off-by: Matthias Maennich <maennich@google.com> Signed-off-by: Dodji Seketeli <dodji@redhat.com> |

Separate public types of first binary from those of the second
In abidiff when the user uses --headers-dir{1,2}, she implicitly
indicates the public types of the first and the second binary. That
means that any type that is defined in a file that is not located
under the directory tree designated by --headers-dir{1,2} is
considered private and any change involving those private types will
be suppressed.
In practice, what happens is that libabigail constructs a suppression
specification which suppress all types that are defined in files that
are not under the directories located by --headers-dir{1,2}.
abidiff has a problem, though. It uses the same private type
suppressions (derived from --headers-dir1 and --headers-dir2) when
looking at the first binary *and* the second binary. It should rather
only use the private type suppression specifications derived from
--headers-dir1 when looking at the first binary, and use the private
type suppression specifications derived from --headers-dir2 when
looking at the second binary.
This problem leads to some false positives like the one reported at
https://gitlab.gnome.org/GNOME/pango/issues/343#note_397761.
This patch fixes this issue by using the private type suppression
specifications derived from --headers-dir1 only when looking at the
first binary, and using the private type suppression specifications
derived from --headers-dir2 only when looking at the second binary.

second binary.

Support having several debuginfo search dirs for a binary
There are use cases where the split debuginfo file of a given binary
is under a given root directory and that the split debuginfo file
itself depends on an alternate debuginfo file that is under another
unrelated root directory.
In that case, the dwarf reader must be able to look for the debuginfo
files under several unrelated root directories. The tools abidiff and
abidw must thus support having several occurences of the option
--debug-info-dir1 (or --debug-info-dir2) meaning that the debuginfo
files for the binary must be looked for under several root
directories.

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.

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.

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.

(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.

is, compare two FILE_TYPE_XML_CORPUS_GROUP if they are present.

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.

(equals): In the overload for classes, compare the virtual member functions while comparing classes. * src/abg-comparison.cc (represent): In the overload for method_decl_sptr, fix the way we compute the highest vtable offset number for a give class_decl.

Bug 21058 - abipkgdiff wrongly drops non-public types
When using abipkgdiff types that are defined in files not present in
the devel packages provided by the --devel1 and --devel2 option are
dropped from the internal representation by default.
This has been designed as such, not only to avoid showing changes on
types that are not part of the public headers of a shared library, but
also to help lower the memory consumption of libabigail.
In this particular bug report, we see a library that uses types (in
its public interface) that are defined in headers of a *different*
package. For instance, suppose a particular package foo that uses
types defined in headers of the glib package. And some of those Glib
types can be present in its public interface.
So in this case, libabigail is dropping a type that is actually part
of the public interface of the library that is being analyzed, even if
the type was not defined in the devel package of the current package.
This patch addresses the issue by doing a number of things:
1/ If a type is defined in a file which path starts with
"/usr/include/", then consider it as a public type. This is so
that type coming from the public interface of other packages, and
that are defined in system headers are considered as part of the
public types of the package being analyzed.
2/ by default, don't drop types not defined in the associated
devel package. This will hinder our ability to decrease the
memory usage, but there have been a number of recent optimization
that help in that regard independently. So I am hoping this
shouldn't have a big impact now.
Incidentally, the option --dont-drop-private-types (from abidiff)
is changed into --drop-private-types, so that interested users can
still drop non-private types from the model, if they wish. That
--drop-private-types option is added to abipkgdiff too.
As the offended types are not dropped from the model anymore, the
usual filtering mechanisms of libabigail can take place.
* doc/manuals/abidiff.rst (--dont-drop-private-types): Remove documentation.
(--drop-private-types): Document this new option.
* src/abg-tools-utils.cc: Update copyright notice
(handle_fts_entry): On the generated suppression specification, do
not set the flag to drop matched types. Also, don't match types
defined in files which patch start with "/usr/include/".
* tools/abidiff.cc (options::options): Initialize the
drop_private_types data member to false.
(display_usage): Remove usage string for
--dont-drop-private-types. Add a new one for
--drop-private-types.
(parse_command_line): Don't part --dont-drop-private-types,
rather, parse --drop-private-types.
(set_suppressions): When the suppression for private types is
generated, if --drop-private-types was provided, then instruct the
suppression to drop matched types.
* tools/abipkgdiff.cc (options::drop_private_types): New option.
(options::options): Initialize the new drop_private_types data
member to false.
(display_usage): Add a usage string for --drop-private-types.

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.

Bug 18754 - Add the "--no-added-syms" option to abidiff
With this option, abidiff is now able to filter out added

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.

A suppressed diff node implies suppressing all equivalent nodes too
When a diff node N is suppressed (for instance, using the
--headers-dir{1,2} option of abidiff}, it's only that diff node that
is suppressed. We forget to suppress diff nodes that are equivalent
to N.
Here is why we forget to suppress diff ndoes that are equivalent.
apply_suppressions walks the diff node graph to mark diff nodes as
suppressed. But it does the walking by making sure each diff node's
*class of equivalence* is visited once. This is not only a way to
prevent infinite loops while visiting the graph, but also an
optimization as it avoids walking two equivalent diff nodes.
But then it can happen that we forget to categorize some diff nodes
inside a given class of equivalence, even though we categorized some
others.
This patch makes it so that when a diff node inside a class of
equivalence is categorized as SUPPRESSED, the canonical diff node of
that class of equivalence is categorized as SUPPRESSED too. That way,
to know if a diff node is suppressed, we just need to look at its
canonical diff node.
While doing this, I noticed that abidiff and abipkgdiff are not
dropping private types from libabigail's internal representation, even
though the Library now has that capability. The patch fixes that.
But then the patch adds a --dont-drop-private-types option to abidiff
to avoid dropping those private types from the IR, so that regression
tests can make sure that a suppressed diff node implies suppression
all equivalent nodes too.
* doc/manuals/abidiff.rst b/doc/manuals/abidiff.rst: Document the
new --dont-drop-private-types option.
* src/abg-comparison.cc (diff::is_filtered_out): If the canonical
type was suppressed then the current diff node is filtered out.

is suppressed.

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.

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.

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".
* doc/manuals/libabigail-concepts.rst: Document the new
'suppress_file' directive.

(read_file_suppression, is_file_suppression, file_is_suppressed):
Define new functions.
(file_suppression::{file_suppression, suppresses_file,
~file_suppression}): Define new member functions.
* tools/abidiff.cc (main): If a suppression specification
suppresses one of the input files, then do not perform the
comparison.
* tools/abipkgdiff.cc (compare): If a suppression specification
suppresses a file that is to be compared, then do not perform the
comparison.
* tools/abicompat.cc (create_diff_context): New static function.
(perform_compat_check_in_normal_mode)
(perform_compat_check_in_weak_mode): Adjust to take a context in
parameter. Do not create a diff context here anymore, do not load
suppression files here either.
(main): Use the new create_diff_context to create a diff context
and initialize it, including loading suppression specifications.
If any suppression specification suppresses a file to load, then
do not load perform any compatibility checking. Adjust
invocations of perform_compat_check_in_weak_mode and
perform_compat_check_in_normal_mode to pass the diff context.

Split suppression engine off of abg-comparison.{cc,h}
Until now, the suppression engine was part of the comparison engine.
The code of both was in the abg-comparison.{cc,h} files.
For the sake of greater modularity, this patch separates the suppression
engine from the comparison engine. The suppression engine now lives
in include/abg-suppression.h and src/abg-suppression.cc. The patch
also updates logical consumers of the suppression engine to adapt them
to the change.
* include/Makefile.am: Add abg-suppression.h to source
distribution.

Add --version option to several libabigail tools
This patch changed the revision number of the libabigail library to
make it reflect the fact that we are not in "release candidate" mode,
before the first 1.0 release. So the revision number is now "rc0".
The configuration manager has been updated to support version numbers
that are strings, so that it can supports things like "rc0".
Then, several libabigail tools have been modified to support the
--version option to display their version number.
* configure.ac: Set the version revision to "rc0".
* doc/manuals/abicompat.rst: Adjust manual for new --version
option.
* doc/manuals/abidiff.rst: Likewise.
* doc/manuals/abidw.rst: Likewise.
* doc/manuals/abilint.rst: Likewise.
* doc/manuals/abipkgdiff.rst: Likewise.
* include/abg-config.h (config::{m_format_minor, m_format_major}):
Make these be strings.
(config::{get,set}_format_minor_version_number): Make these return
strings.
(config::{get,set}_format_major_version_number): Make these return
or take strings.
(abigail_get_library_version): Make this take strings.
* src/abg-config.cc (config::config): Adjust.
(config::{get,set}_format_major_version_number): Make these return
or take strings.
(config::{get,set}_format_minor_version_number): Make these return
strings.
(abigail_get_library_version): Make this take strings.
* include/abg-version.h.in: Make the version variables be strings.
* src/abg-writer.cc (write_translation_unit): The version numbers
are now strings so adjust.
* tools/{abicompat,abidiff,abidw,abilint,abipkgdiff,abisym}.cc
(options::display_version): New data member.
(options::options): Initialize it.
(display_usage): Add documentation for new --version option.
(parse_command_line): Parse new --version option.
(main): Support --version.
