Support source_location_not_in and source_location_not_regexp suppressions
This patch adds support for properties source_location_not_in and
source_location_not_regexp in the [suppress_type] section of
suppression specifications. So the suppression specification:
[suppress_type]
source_location_not_in = foo1.h, foo2.h bar1.h bar2.h
suppresses ABI change reports about types that are *NOT* defined in
files foo{1,2}.h and bar{1,2}.h. The intended use of this construct is to
constrain abi change reports to types that are part of the API of a
given shared library. The API of the library is supposed to be
defined in foo.h and bar.h only.
Similarly, the suppression specification:
[suppress_type]
source_location_not_regexp = (foo|bar){1,2}\\.h
suppresses ABI change reports about types that are not defined in the
same set of files foo1.h, foo2.h, bar1.h and bar2.h.

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

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

Support filtering out just one alias of a function
Suppose a function private_foo() has a symbol private_foo and also a
another one (an alias) named public_foo. Then suppose we want to
filter out sub-type changes to private_foo(). But then we still want
to see changes to public_foo.
This patch does add this feature. The [suppress_function] directive
now has a new (hidden) boolean 'allow_other_aliases' property. When
set to 'yes' or 'true', if the function being looked at has an alias
symbol that does *NOT* match the other properties of the directive,
then the directive doesn't suppress reports for the function. This
new property is set to yes by default.
This means that when a function has got multiple aliases, to suppress
the function, one needs to write a regular expression that matches the
names of aliases. Otherwise the function will not be suppressed.

set}_allow_other_aliases): Declare new member functions.

(corpus_diff::report): Fix the printing of function aliases when
printing sub-type changes to properly emit the plural of the word
'symbol' when the function has several aliases.

new member function.

Apply suppression specifications to added and removed functions and variables
Until now, specifications for suppressing change reports were applied
only to functions and variables that have sub-type changes. Change
reports about function and variables that were added or removed could
not be suppressed.
This patch makes suppression specifications to apply to added and
removed functions and variables too. They can also apply to function
and variable symbols that are not referenced by any debug info.
The patch also fixes some typo and formatting glitches and updates
some existing tests accordingly.

Support new 'accessed_through' suppression property
It turned out it's important to be able to suppress changes about
types that are reachable from a function parameter only through e.g, a
pointer or a reference, so that only changes types that are reachable
directly from a function parameter are emitted.
This patch adds that feature.
While doing this, I noticed this: Suppose a diff node D2 is marked as
being redundant with a diff node D1 seen previously. So only D1 is
reported; D2 is not, because it's been filtered out, because it's
redundant with D1. But then suppose D1 is filtered out, due to a
suppression specification. At that point, D2 should not be marked
redundant anymore, and should be reported.
Of course, the code before this patch was wrongly filtering D2 *and*
D1 out. So this patch fixes that.

Define new enum.

Support specifying data member insertion in suppressions
This patch is for supporting this kind of things:
[suppress_type]
name = S
has_data_member_inserted_between = {8, end}
or:
[suppress_type]
name = S
has_data_members_inserted_between = {{8, 31}, {64, end}}
or:
[suppress_type]
name = S
has_data_members_inserted_at = offset_after(member0)
How cool is that, heh?
Anyway, to do this, the patch adds support for tuple values (i.e,
lists of values) in INI files.
Then on top of that the patch adds support for the specific

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.

Do not mark sibling structurally identical nodes as redundant
Consider the C code below:
int
foo(int a, int b)
{
}
that is changed as:
float
foo(float a, float b)
{
}
In this case, we want the 'abidiff' tool to report the three
occurrences of the 'int' -> 'float' change (in the return type and in
the two parameter changes of the function foo).
In the current code, the comparison engine only reports the first
occurrence of the change and consider the two other occurrences as
being redundant. So, by default, it only reports the first occurrence
of the change.
This patch modifies the comparison engine to make it *NOT* mark the
two later occurrences of change as redundant because the three
occurrences of changes happen at the same logical level: they are all
children of the function diff node in the diff tree.

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'.

Temporarily disable redundant diff report elimination
So, this is all about problem report https://sourceware.org/bugzilla/show_bug.cgi?id=17693. When redundant diff node reporting is enabled and when a diff node appears twice in a diff tree, we detect that and the second occurrence of the diff node is flagged as being redundant. Later at diff tree node reporting time, the redundant diff node is not reported. The problem is that diff nodes are canonicalized. That is, when the same change is present twice in a diff, the same diff node is going to be present twice. So flagging the second occurrence as being redundant amounts as flagging the first occurrence as being redundant too! So at reporting time, the diff tree visitor that walks the diff tree nodes will avoid reporting the two occurrences of diff tree nodes altogether. This is what happens in the example of the bug above. I am reproducing the example here for convenience: So suppose we have a first version of a library named lib-v0.so which is made of this C code: int add(int a, int b) { } Then suppose that code was changed in a subsequent version of the library named lib-v1.so, leading to the following code: int add(float a, float b) { } So, the diff tree node for the 'add' function is going to have several child diff tree nodes, among which, one that carries the change for the first parameter (int a becoming float a) and the one carrying the change for the second parameter (int b becoming float b). The diff tree node for the second parameter is going to be same diff tree node as the one for the first parameter because what counts is the change in the *type* of the parameter. Thus, the diff tree node for the second parameter is going to be marked as being redundant; and so is the first parameter. So abidiff lib-v0.so lib-v1.so yields: Functions changes summary: 0 Removed, 0 Changed (1 filtered out), 0 Added function Variables changes summary: 0 Removed, 0 Changed, 0 Added variable You can see that even the function 'add' is not mentioned in the report. This is because it has also been considered as being redundant because of a phenomenon named 'propagation'. The redundant-ness of the children nodes of the diff tree node of the 'add' function is propagated to the diff tree node of the add function itself because that add function diff tree node has no child but redundant diff children nodes. This categorization behaviour is correct. What is not correct is that only the second child node of the add function diff tree node should have been marked redundant. I am going to tackle this issue a bit later. For now, I am temporarily disabling redundancy categorization for diff tree nodes by default. Hence this patch. With this patch, abidiff lib-v0.so lib-v1.so yields: Functions changes summary: 0 Removed, 1 Changed, 0 Added function Variables changes summary: 0 Removed, 0 Changed, 0 Added variable 1 function with some indirect sub-type change: [C]'function int add(int, int)' has some indirect sub-type changes: parameter 0 of type 'int' changed: name changed from 'int' to 'float' parameter 1 of type 'int' changed: name changed from 'int' to 'float' Note how the change on the second parameter appears equal to the change on the first. * src/abg-comparison.cc (diff_context::priv::priv): Show redundant changes by default.

of this enum is changed to handle whether diff node children
should be visited or not. So the enumerators are now

Properly propagate {REDUNDANT, SUPPRESSED}_CATEGORY wrt local changes
* src/abg-comparison.cc
(suppression_categorization_visitor::visit_end): If a diff node
carries local changes, then, even if all of its children node have
been suppressed, this diff node shall not be categorized as
suppressed by way of propagation.
(redundancy_marking_visitor::visit_end): If a diff node carries
local changes, then, even if all of its children nodes are
redundant, this diff node shall not be categorized as being
redundant by way of propagation.
