fixes that by making the helper

calls that.

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.

There are times where the DW_AT_data_member_location attribute is set
to zero and where the actual offset of the data member is the value of
the DW_AT_bit_offset. This seems to be happening when a union type is
involved.
To get the offset of a data member, this patch makes us read the
DW_AT_bit_offset when it's present. Otherwise, it gets the offset
from the DW_AT_data_member_location as we used to do.
In the passing the patch fixes the offset of base classes; the
nubmer of bytes value was what was being used, rather than the number
bits value.
* src/abg-dwarf-reader.cc (die_member_offset): Better comments.
Support reading the bit offset also from the DW_AT_bit_offset
attribute when it's present. Make sure this always returns a
value in bits.

value returned by die_member_offset anymore because it's now in

Until now, when reporting about struct or union changes, data members
were sorted by using their offset; the data member with the smallest
offset coming first.
But then in unions, all data member have the same offset. In that
case, the patch sort them lexicographically, by taking their name into
account.

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.

strip_typedef re-constructs entire type trees and canonicalize them.
Calling it a lot on very deep and recursive trees can be costly.
Unfortunately, categorization of changes uses strip_typedef quite a
bit to determine if the two types that are different are still
compatible. When used on changesets generating from comparing two
Linux Kernels, it makes changes categorization dominate CPU usage
profiles.
This patch avoids using strip_typedef to determine if two types are
compatible and thus speeds up type categorization of changes involving
lots of deep and recursive type trees.

Until now, integral_type has been just a "private" helper type used in
the building of a type_decl.
Now it's going to be helpful in determining the name of an integral
type, directly from DIEs -- without having to build a type_decl.
This patch factorizes out the parsing and building of an integral_type
by introducing a src/abg-ir-priv.h file that is meant to declare
interfaces that are going to be private to libabigail.so but usable by
all of its modules.
* src/abg-ir-priv.h: New file.

The is_member_decl() function considers that a decl is a member decl
only if it's at class scope.
In preparation for the support of incremental building of method
decls, a method decl, even before being added to its final class, must
always be considered as a member decl. This allows for instance, the
proper pretty printing of the method decl even before it's added to
its class.
This patch prepares the upcoming support of incremental building of
method decls by making is_member_decl() work on a method_decl that
hasn't yet been added to a class, so that is not, strictly-speaking,
at class scope yet.

Inside a given ABI corpus, during type canonicalization, function
types are compared structurally (member-wise). Note that on the other
hand, class, enums and basic types are compared using an ODR-based

with a lot of function types.

optimization for function types too, during type canonicalization.

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

During type canonicalizing, qualified types are being compared using
the ODR-based optimization. This is wrong because, for instance, it's
not because two types from the same ABI corpus are both const
anonymous structs that they are meant to be equivalent.
This patch fixes the issue by applying the ODR-based comparison
optimization only to built-in types and non-anonymous struct and
enums.
The reproducer is a glibc package that takes a while to compare so
it's not suitable for inclusion in the test suite.

When applying suppressions to diff graphs, if the same diff node
appears twice in the graph in a way that creates a cycle, we can get
trapped in the cycle when walking the graph. That results in a an
infinite loop. Note that the infinite loop appears in the
diff::traverse member function, in the for-loop that walks the
children nodes of a given node.
This patch avoids walking the same node twice when applying
suppressions.
The test binaries that exhibit the issue come from the two following
packages:
rh-mariadb101-mariadb-10.1.14-2.el6 and rh-mariadb101-mariadb-10.1.16-1.el6.
The sub-packages compared are
rh-mariadb101-mariadb-server-10.1.14-2.el6.x86_64.rpm and
rh-mariadb101-mariadb-server-10.1.16-1.el6.x86_64.rpm.
The debug info packages are
rh-mariadb101-mariadb-debuginfo-10.1.16-1.el6.x86_64.rpm and
rh-mariadb101-mariadb-debuginfo-10.1.14-2.el6.x86_64.rpm.
Once the packages are properly extracted the command line that
exhibits the infinite loop is:
abidiff --d1 rh-mariadb101-mariadb-10.1.14-2.el6.x86_64/usr/lib/debug --d2 rh-mariadb101-mariadb-10.1.16-1.el6.x86_64/usr/lib/debug rh-mariadb101-mariadb-10.1.14-2.el6.x86_64/opt/rh/rh-mariadb101/root/usr/lib64/mysql/plugin/ha_connect.so rh-mariadb101-mariadb-10.1.16-1.el6.x86_64/opt/rh/rh-mariadb101/root/usr/lib64/mysql/plugin/ha_connect.so
This patch has no test because of the cheer size of these packages;
the debug info packages alone take more than 100MB :-( I really hope
we set up a separate repository with big test packages to overcome
this. Maybe something using fedabipkgdiff ...

Symbols of pretty much all member functions of types that are meant to
be "private" to translation units that contribute to libabigail.so
were exported because we didn't do much to prevent that.
This patch starts controlling the set of symbols that are exported.
By default, symbols of any entity declared in a translation unit that
contributes to libabigail.so are hidden by default. Only symbols of
entities declared in public headers (headers in include/*.h) are
exported.
There are many ways to achieve that. This patch chooses to avoid
cluttering declarations of entities in the public header by adding
__attribute__((visibility="default")) to every declared type of
function in there.
Rather, the patch uses "#pragma GCC visibility push(default)" before
entities declared on those headers. By doing so, all those entities
have their symbol marked as "visible" by the compiler. Once the
header are #included, the #pragma GCC visibility pop" is used, so that
anything else has its symbol be hidden from that point on.
Note that for ease of maintenance the patch uses the macros
ABG_BEGIN_EXPORT_DECLARATIONS and ABG_END_EXPORT_DECLARATIONS rather
than using the pragma directive directly.
I believe this is a more elegant way of handling visibility, compared
to cluttering every single declaration in public headers with a
"__attribute__((visibility=("default")))" or with a macro which
expands to it.
This reduces the the set of symbols exported by libabigail.so from
20000+ to less than 5000.
* VISIBILITY: New documentation about this visiblity business.
* CONTRIBUTING: Update the "contributing guide" to refer to symbol
visibility issues.
