During structural comparison of types there is the possibilitiy of infinite recursion as types can have self-references and there can be more elaborate mutual references between them. The current comparison algorithm keeps track of currently seen (struct and function) types by name. This causes earlier caching of names than is needed and, more significantly, may result in types comparing equal unexpectedly. This commit switches to storing their addresses instead. This change affects some tests which show more diffs than previously. src/abg-ir.cc: (environment::priv): Change types of classes_being_compared_ and fn_types_being_compared_ to be simple sets of pointers. (function_type::priv::mark_as_being_compared): Just add address to set. (function_type::priv::unmark_as_being_compared): Just remove address from set. (function_type::priv::comparison_started): Just look up address in set. (class_or_union::priv::mark_as_being_compared): Just add address to set. (class_or_union::priv::unmark_as_being_compared): Just remove address from set. (class_or_union::priv::comparison_started): Just look up address in set. * tests/data/test-diff-dwarf/PR25058-liblttng-ctl-report-1.txt: Update. * tests/data/test-diff-pkg/elfutils-libs-0.170-4.el7.x86_64-multiple-sym-vers-report-0.txt: Update. * tests/data/test-diff-pkg/spice-server-0.12.4-19.el7.x86_64-0.12.8-1.el7.x86_64-report-2.txt: Update. * tests/data/test-diff-pkg/spice-server-0.12.4-19.el7.x86_64-0.12.8-1.el7.x86_64-report-3.txt: Update.

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.
