When the the of 'equals' overloaded functions was introduced, it was
to get the possibility to have a hint about the kind of difference
(local or sub-type difference) there was between two different ABI
artifacts. To do that, it was quite common to keep on comparing the
two artifacts even when we knew there were different, because we need
to know all the kinds of the differences there are.
Now, profiling shows that doing this generally is too costly. So,
this patch adds a way to doing it only when necessary.
* include/abg-ir.h (equal): Turn the last parameter of type
change_kind& into a change_kind*. Do this on all the overloads'
declarations.
* src/abg-ir.cc (equal): Do the same for the definitions of the
overloads and adapt them to report about the kind of changes makes
the two ABI artifact different -- only if the change_kind pointer
is non-null. That way, callers have a way to choose if they want
to go the expensive route of knowing what kind of changes there
are.

signature of equals; call it with the change_kind* parameter set
to NULL.

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 comparing two ABI Corpuses, 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.
