The leaf-changes-only reporting path does not report on all the same
kinds of differences as the default reporting path does, such as
reporting about changes to variables, even though they can be
considered leaf changs.
- The addition or removal of any symbol affects the ABI and is
clearly a leaf change.
- A change to a variable's declaration may be local rather than
caused by a type change elsewhere.
This patch adds these missing pieces and reorders some of the existing
leaf reporting, bringing the default and leaf corpus_diff functions
closer to the point where they can be trivially merged or refactored.
This patch also corrects an error in reporting the total number of
leaf changes.
* doc/manuals/abidiff.rst: Update the documentation for
--leaf-changes-only.
* doc/manuals/abipkgdiff.rst: Likewise.
* src/abg-comparison.cc (emit_diff_stats): Exclude non-leaf
changes to variables from the reported total of leaf changes.
* src/abg-default-reporter.cc (report): In the corpus_diff
override, move some code and comments for clarity.
* src/abg-leaf-reporter.cc (report): In the corpus_diff
override, additionally report removed/added/changed variables
and removed/added symbols absent from debug info.
* tests/data/Makefile.am: Add new test case files.
* tests/data/test-abidiff-exit/test-leaf0-report.txt: Update
to include reporting of variable diff (change of type).
* tests/data/test-abidiff-exit/test-leaf1-report.txt: New test
case with added/removed variables/functions and changed
variables (both local and non-local type changes).
* tests/data/test-abidiff-exit/test-leaf1-v0.cc: Ditto.
* tests/data/test-abidiff-exit/test-leaf1-v0.o: Ditto.
* tests/data/test-abidiff-exit/test-leaf1-v1.cc: Ditto.
* tests/data/test-abidiff-exit/test-leaf1-v1.o: Ditto.
* tests/test-abidiff-exit.cc: Run new test case. Supply
--redundant otherwise the test isn't meaningful.

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.
