Bug 18342 - Segmentation fault while comparing functions with variadic parameters
In the IR built from DWARF, a variadic variadic parameter has an empty
type. Later during type comparison, comparing an empty (NULL) type
with other types proves to be troublesome.
This patch handles the issue by creating a new kind of
abigail::type_decl type specifically for variadic parameters. This is
like what is done for void types.
After that it appears that the categorizing sub-system flags a change
of variadic type to non-variadic type as redundant if that change
appears several times on different functions. We don't want that
because it can hide important changes we want to see. The patch fixes
that too.

pointer.

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

Expose a new libabigail::tools_utils namespace
The utilities present in this namespace were previously living in
tools/abg-tools-utils.h and tools/abg-tools-utils.cc. They were not
exported and were meant to be useful to the tools writting in the
tools/ directory. I realized that these utilities might be useful to
clients of the libabigail library in general so I am making them
available generally. Note that the initial name of the namespace was
libabigail::tools; so renaming it to libabigail::tools_utils required
that I adjust some client code. I have also cleaned up the code,
interfaces and their apidoc a little bit.
* include/abg-tools-utils.h: Moved tools/abg-tools-utils.h in
here. Renamed the namespace tools into tools_utils. Inject
std::ostream, std::istream, std::ifstream, and std::string types
into the tools_utils namespace. Adjust the function declarations
accordingly. Remove the useless dirname() function declaration.
* include/Makefile.am: Add abg-tools-utils.h to the list of
exported headers.
* src/abg-tools-utils.cc: Moved tools/abg-tools-utils.cc in here.
Renamed the namespace tools into tools_utils.
(get_stat): Add apidoc.
(is_dir): Cleanup apidoc.
(dir_name); Cleanup parameter name.
(guess_file_type): Cleanup parameter type.
* src/Makefile.am: Add abg-tools-utils.cc to the list of exported
headers.
* tools/Makefile.am: Do not build the temporary library
libtoolsutils.la anymore as abg-tools-utils.{h,cc} have moved out
of this directory.
* tools/abicompat.cc (parse_command_line, main): Adjust for tools

Un-share diff nodes in the comparison IR
Until now, the diff nodes of the comparison IR were shared. That is,
two diffs about the same subjects were represented by the same diff
node that would appear twice in the tree.
This was preventing us from spotting e.g, the first occurrence of a
diff node that would later (in the tree) turn to be redundant because
all redundant diff nodes are represented by the same diff node
pointer.
This patch now makes each diff node be different, as far of pointer
comparison is concerned. But it introduces the concept of canonical
diff node to ease the comparison between two diff nodes. Two diff
nodes that are equal have the same canonical diff node.
With this facility, it's now possible to tell the difference between
diff nodes that are (structurally) equal. It's not possible to say
things like "this is the first or second occurrence of the redundant
diff node foo'.

Support reading and comparing soname from ELF files
Libabigail's DWARF reader doesn't read the DT_SONAME tag from the
.dynamic section. The abigail::corpus type doesn't have a property
for that tag either. And the comparison engine doesn't take that tag
in when comparing corpora.
This patch modifies the DWARF reader to read the DT_SONAME and
DT_NEEDED tags from the .dynamic section. The value of DT_SONAME tag
is then saved in the new corpus property accessed by the new
abigail::corpus::get_soname() accessor. The comparison engine has
also been modified to compare the sonames of two corpora being
compared. Note that the value of the DT_NEEDED elf tag is saved in a
new corpus property that is accessed via the new
abigail::corpus::get_needed() getter. This property is not used yet.
This patch also adds a unit test for this new feature.
