Following the changes to represent changed anonymous unreachable enums,
this patch does the same for anonymous unreachable unions, classes and
structs.
Basically, without this patch, this change:
union
{
int a;
int b;
};
------
union
{
int a;
int b;
int c;
};
yields:
1 removed type unreachable from any public interface:
[D] 'union {int a; int b;}' at test_1.c:1:1
1 added type unreachable from any public interface:
[A] 'union {int a; int b; int c;}' at test_2.c:1:1
But with the patch, it does yield:
1 changed type unreachable from any public interface:
[C] 'union {int a; int b;}' changed:
type size hasn't changed
1 data member insertion:
'int c' at test-anon-union-v1.c:5:1
type changed from:
union {int a; int b;}
to:
union {int a; int b; int c;}
* include/abg-fwd.h (class_or_union_types_of_same_kind)
(is_data_member_of_anonymous_class_or_union): Declare new
functions.
* include/abg-ir.h (lookup_data_member): Likewise, declare a new overload.
* src/abg-ir.cc (class_or_union_types_of_same_kind)
(lookup_data_member, is_data_member_of_anonymous_class_or_union):
Define news functions & overloads.
* src/abg-reporter-priv.cc (represent): When representing a change
in the name of a data member, if the context is an anonymous type,
use the non-qualified name of the data member, not its qualified
name.
* src/abg-comparison.cc
(corpus_diff::priv::ensure_lookup_tables_populated): Handle
deleted/added anonymous enums, unions, classes and structs
similarly. That is, if an anonymous type was removed and another
one got added, if they both have data members (or enumerators) in
common, then we are probably looking at an anonymous type that was
changed. This is because these anonymous types are named using
their flat representation.
* tests/data/test-abidiff-exit/test-anon-types-report-1.txt: New
reference test comparison output.
* tests/data/test-abidiff-exit/test-anon-types-v{0,1}.o: New
binary tests input files.
* tests/data/test-abidiff-exit/test-anon-types-v{0,1}.c: Source
code of new binary test input.
* tests/data/Makefile.am: Add the new test material above to
source distribution.
* tests/test-abidiff-exit.cc (in_out_specs): Add the test inputs
above to this test harness.

This is the Application Binary Interface Generic Analysis and Instrumentation Library. It aims at constructing, manipulating, serializing and de-serializing ABI-relevant artifacts. The set of artifacts that we are intersted is made of quantities like types, variable, functions and declarations of a given library or program. For a given library or program this set of quantities is called an ABI corpus. This library aims at (among other things) providing a way to compare two ABI Corpora (apparently the plural of corpus is copora, heh, that's cool), provide detailed information about their differences, and help build tools to infer interesting conclusions about these differences. You are welcome to contribute to this project after reading the files CONTRIBUTING and COMMIT-LOG-GUIDELINES files in the source tree. Communicating with the maintainers of this project -- including sending patches to be include to the source code -- happens via email at libabigail@sourceware.org.
