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.

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, fonctions 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.
