Use worker threads pattern to speed up some tests
We are going to need to speed up more and more tests, and coding directly with libpthread for that can be tedious and bug-prone. So I devised an implementation for the worker threads design pattern instead, and used it to speed up some tests. * include/Makefile.am: Add the new abg-workers.h to source distribution. * include/abg-workers.h: New file. * src/Makefile.am: Add the new abg-worker.cc to source distribution. * src/abg-workers.cc: New file. * tests/test-utils.cc: Update copyright. Make get_src_dir() and get_build_dir() return a const char*, as opposed to returning a string. Make that const char reside in thread local storage, so that two concurrent threads can safely call these functions in parallel, without any race. * tests/test-utils.h: Make get_src_dir() and get_build_dir() return a const char*, as opposed to returning a string. * tests/test-abicompat.cc: Update copyright.

Bug 18535 - abidiff reports false positive ABI difference for libstdc++
When the DWARF reader of libabigail sees a data member for a given class flagged as being a declaration, it considers the declaration as being a definition. The reason why it doesn't strictly trust the "is_declaration" flag of DWARF is that some DWARF producers sometimes wrongly emit that flag. But then, it turns out that a class declaration can have a *static* data member without loosing its declaration-only property. This patch thus changes the behaviour of the DWARF reader to make it consider the class declaration as being a definition when the class has a *non-static* data member; a static data member only is not enough to make the class declaration become a definition. * src/abg-dwarf-reader.cc (build_class_type_and_add_to_ir): The presence of a data member shouldn't make a declaration-only class loose its declaration-only-ness; the presence of a enon-static* data member should. * tests/data/test-read-dwarf/test15-pr18892.so.abi: Adjust. * tests/data/test-read-dwarf/test16-pr18904.so.abi: Likewise. * tests/data/test-diff-filter/test31-pr18535-libstdc++-4.8.3.so: New binary test input. * tests/data/test-diff-filter/test31-pr18535-libstdc++-4.9.2.so: Likewise. * tests/data/test-diff-filter/test31-pr18535-libstdc++-report-0.txt: New test reference output. * tests/data/Makefile.am: Add the new test material to the build system. * tests/test-diff-filter.cc (in_out_specs): Add the new test inputs to the set of inputs to consider.

Fix redundancy marking for change of types used directly
If a type T is used directly (i.e, not through a pointer or reference)
as a function parameter or as a base class, a change in T should never
be marked as redundant in that context. Otherwise, the change in that
context might be filtered out, possibly hiding real ABI incompatible
changes.
This patch implements this policy.
Also, it turned out in some circumstances, we where marking the first
visited diff node of a given class of equivalence of nodes as being
redundant, while we should only mark the *subsequently* visited nodes
of that class of equivalence as visited. The patch also fixes that.
* include/abg-comparison.h (pointer_map): Make this be a map of
{size_t, size_t} pairs, rather than {size_t, bool}, so that each
pointer in the map can be associated to another one.
(diff_context::diff_has_been_visited): Return the pointer to the
first diff node of the equivalence class that has been visited.
* src/abg-comparison.cc (is_pointer_diff, is_reference_diff)
(is_reference_or_pointer_diff, is_fn_parm_diff, is_base_diff)
(is_child_node_of_function_parm_diff, is_child_node_of_base_diff):
Define new static functions.
(diff_context::diff_has_been_visited): Return the pointer to the
first diff node of the equivalence class that has been visited.
(diff_context::mark_diff_as_visited): Save the pointer to the
first diff node of a given class of equivalence that has been
visited.
(redundancy_marking_visitor::visit_begin): If a diff node is a
child node of a function parameter diff or base diff node and if
it's not a pointer or reference diff node, then do not mark it as
redundant. Also, make sure to not mark the first diff node of a
given class of equivalence that has been visited, as redundant;
only the other subsequent nodes should be marked redundant; we
were hitting this case because of an optimization that makes
equivalent class diff nodes to share their private (pimpl) data.

Fix redundancy propagation on node with filtered local changes
Until now, if a diff node N has a local change, even if all of its
children nodes are redundant, N is not considered as being redundant.
This is an issue if the local changes of N are filtered out; in that
case, N should be considered redundant.
This patch fixes that. It introduces a second category bitmap on the
diff node that stores the categorization of the diff node that does
*NOT* take in account the categories inherited from its children
nodes. That way, it's possible to know if the *local changes* of a
given node have been filtered out.

Fix redundancy categorization propagation
Propagating redundancy categorization is broken for cases where there
is a diff node that has children nodes carrying changes that are all
filtered out. In that case, if among those children changes there is
a redundant change, normally the parent diff node we are look at
should be marked redundant too. The bug is that it's not marked as
redundant at the moment. This patch fixes that.

Fix chaining of descendant node of qualified type diff node
While looking at the abidiff report emitted for two versions of the
TBB library, I noticed that some diff nodes were not marked as
redundant as they should be. As a result, they were being reported as
having "been reported earlier", which seems to be an acceptable cruft
to me especially now that the comparison IR can do proper redundancy
detection and marking.
I tracked that down and it's because the child node of a
qualified_type_diff is just the underlying type diff node, whereas
during reporting, we report about the leaf underlying type diff node,
which can be different from the just the underlying type diff node
because the later is always non-qualified.
The fix is to make the child node of qualified_type_diff be the leaf
underlying type diff node, so that diff tree walking (for the purpose
of redundancy detection) and reporting are all looking at the same
tree.
* include/abg-comparison.h
(qualified_type_diff::leaf_underlying_type_diff): Declare new
accessor.
* src/abg-comparison.cc (get_leaf_type): Forward declare this

Recognize cyclic diff tree nodes as being redundant
Okay I need to introduce some vocabulary here. Suppose we have the
version 1 of a library named library-v1.so which source code is:
struct S
{
int m0;
struct S* m2;
};
int
foo(struct S* ptr)
{
return ptr;
}
And now suppose we have a version 2 of that library named
library-v2.so which source code is modified so that a new data member
is inserted into struct S:
struct S
{
int m0;
char m1; /* <--- a new data member is inserted here. */
struct S* m2;
};
int
foo(struct S* ptr)
{
return ptr;
}
struct S is said to be a cyclic type because it contains a (data)
member which type refers to struct S itself, namely, the type of the
data member S::m2 is struct S*, which refers to struct S.
So, by analogy, the diff node tree that represents the changes of
struct S is also said to be cyclic, for similar reasons: the diff
node of the change of S::m2 refers to the diff node of the change of
the type of S::m2, namely the diff node of struct S*, which refers to
the diff node for the change of struct S itself.
Now let's talk about redundancy. When walking the diff node tree of
struct S in a depth-first manner, at some point, we look at the diff
node for the data member S::m2, and we end up looking at the diff node
of its type which is the diff node for struct S*; we keep walking and
eventually we look the diff node of the change of the underlying type
of struct S, which is the diff node of struct S, and hah! that is a
redundant node because it's the first node that we visited when
visiting the diff node of ... struct S! So the diff tree node for
the change of struct S is not only a cyclic node, it's a redundant
diff node as well, and its second occurrence is located at the point
of appearance of data member S::m2. Hence the wording "cyclic
redundant diff tree node". There! We have our vocabulary all set now.
This patch enhances the code of the comparison engine so that a cyclic
diff tree node is marked as redundant from the point of its second
occurrence, onward.
First the patch separates the notion of visiting a diff node from the
notion of traversing it. Now traversing a diff node means visiting it
and visiting its children nodes. So one can visit a node without
traversing it, but one can not traverse a node without visiting it.
So, when walking diff node trees, we need to avoid ending up in
infinite loop in presence of cyclic nodes. This is why re-traversing
a node that is already being traversed is forbidden by this patch, but
visiting a node that is being visited is allowed. Before this patch,
the notions of visiting and traversing were conflated in one and were
not very clear; and one couldn't visit a node that was currently being
visited. As a result, in presence of a cyclic node, its redundant
nature wasn't being recognized, and so the diff tree node was not
being flagged as being redundant. Diff reports were then cluttered by
redundant references to changes involving cyclic types.

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

clients of the libabigail library in general so I am making them

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.

Make determining of compatible types complete
Until now, two types that are different were considered compatible if
one type is a typedef of the other. This is useful because two
different types, if compatible, are not ABI-incompatible. This patch
extends the concept of compatible types to types which might have
sub-types that are typedefs of each others, including function types.
Note implementing this required that I fixed various other things left
and right. Like style fixes, crash avoiding fixes, etc.
* include/abg-fwd.h (is_reference_type, is_function_type)
(is_method_type): Declare new predicates.
* include/abg-ir.h (class qualified_type_def): Pimpl this class.
(qualified_type_def::qualified_type_def): Use the convenience
type_base_sptr typedef.
(qualified_type_def::{get_cv_quals, set_cv_quals}): Use the
qualified_type_def::CV type rather than char.
(qualified_type_def::get_underlying_type): Use the convenience
type_base_sptr typedef.
(pointer_type_def::pointer_type_def): Likewise.
(function_decl::parameter::parameter): Add a new constructor.
* src/abg-ir.cc (is_reference_type, is_function_type)
(is_method_type): Define new predicates.
(class qualified_type_def::priv): Define this new private type,
for the purpose of Pimpl-ifying the qualified_type_def class.
(qualified_type_def::{qualified_type_def, build_name,
get_cv_quals_string_prefix, get_underlying_type}): Adjust for the
purpose of Pimpl-ifying the qualified_type_def class.
(equals): In the qualified_type_def, reference_type_def overloads,
trust the fact that we have operator== overload for the
type_base_sptr. This avoids crashes for when the (possible)
underlying type is null.
(pointer_type_def::operator==): Likewise.
(strip_typedef): Make this recursively strip
typedefs from sub-types.
(types_are_compatible): Handle null types.
(qualified_type_def::{get_cv_quals, set_cv_quals}): Handle
qualified_type_def::CV rather than char.
(pointer_type_def::pointer_type_def): Use the convenience
type_base_sptr typedef.
* include/abg-comparison.h (distinct_diff::compatible_child_diff):
Declare new member function.
* src/abg-comparison.cc (distinct_diff::compatible_child_diff):
Define new member function.
(distinct_diff::chain_into_hierarchy):
Chain the compatible child diff node that might be present.
(distinct_diff::report): Now when a distinct diff carries a
compatible change, mention it in the report.
* src/abg-comp-filter.cc (is_compatible_change): A compatible
change can now involve types that are not typedefs. Only their
sub-types need to be involved with typedef-ness.
* tests/data/test-diff-dwarf/test{2,4,5}-report.txt: Adjust.

over.

Do not hook type diff nodes to a parent
A given diff node for a type can be hung off of several contexts: a
function parameter type node, another type diff node, etc. For that
reason, a type diff node should not have a parent node. Thus, it's
should be the job of the context containing the type diff node to
propagate its categories to the context nodes. This actually fixes a bug
about category propagation.
* abg/comparison.cc (var_diff::var_diff): Do not set parent node
for the type diff of the var_diff.

type diff node to the var_diff node.
