In this problem report, the issue is that when comparing two corpus
groups, especially when looking up function/variable symbols, the
get_fun_symbol_map() and get_var_symbol_map() member functions used
are corpus::get_{fun,var}_symbol_map, rather than
corpus_group::get_{fun, var}_symbol_map. Note that the type
corpus_group inherits from the type corpus. That leads to unexpected
comparison results, especially for symbols.
This patch fixes this by making the corpus::get_{fun, var}_symbol_map
member function be virtual and by using it during the lookup of
function/variable symbols. That way, the right symbol map gets used.
* include/abg-corpus.h (corpus{_group}::get_{fun,
var}_symbol_map): Make these member functions virtual.
* src/abg-corpus.cc (corpus::lookup_{function, variable}_symbol):
Use the virtual corpus::get_{fun, var}_symbol_map() member
function to get the symbols of the current corpus or corpus_group.
* tests/data/Makefile.am: Add the new test input material below to
source distribution.
* tests/data/test-abidiff/test-PR24552-report0.txt: New test input.
* tests/data/test-abidiff/test-PR24552-v0.abi: Likewise.
* tests/data/test-abidiff/test-PR24552-v1.abi: Likewise.
* tests/test-abidiff.cc (main): Support comparing corpus groups.
(specs): Add the new test inputs to the 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, 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.
