While comparing two function types a given sub-type can itself have a
sub-type that *is* the same function_type as the one we are looking
at. In that case, an infinite loop appears.
This patch detects those cases, similarly to what we do for class_decl
and avoids the eventual infinite loop.
* include/abg-ir.h (class environment): Make class function_type
be a friend of this class.
(class function_type): Make the equality function for
function_types be a friend of this class.
* src/abg-ir.cc (environment::priv::fn_types_being_compared_): New
data member.
(function_type::priv::{mark_as_being_compared,
unmark_as_being_compared, comparison_started}): Define new member
functions.
(equals): In the overload for function_types, if any of the the
function_type being compared is already being compared, return
early saying that the two function_types are equal. This avoids

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.
