There are two kinds of data member changes:
1/ changes to the type or offset of a given data member
basically, in this kind of change, the name of the data member
remained the same.
2/ changes where the data member (at a given offset) was replaced by
something else completely.
Today, the comparison engine recognizes these two kinds of changes and
records them in two different data structures. This is useful because
it allows for a finer grain analysis.
But when we report these changes, today, we report them separately and
sometimes that doesn't make sense. For instance, because there is no
change of the 1/ kind, the reporter would say "no data member
changes", and yet go ahead and emit data member changes of the 2/ kind.
This patch groups the reporting of the two kinds of changes so that
when it says "no data member changes", it means there was no data
member changes at all.

* src/abg-default-reporter.cc (default_reporter::report): In the
class_or_union_diff& overload, group the reporting of the changes
to data member sub-types with the replacement of data members.
These are just data member changes after all. Use the newly
declared accessors for better measure.
* src/abg-leaf-reporter.cc (leaf_reporter::report): Likewise.
* tests/data/test-diff-dwarf/test45-anon-dm-change-report-0.txt: Adjust.
* src/abg-leaf-reporter.cc (leaf_reporter::report): Likewise.
* tests/data/test-diff-pkg/spice-server-0.12.4-19.el7.x86_64-0.12.8-1.el7.x86_64-report-2.txt:
Likewise.

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.
