strip_typedef(), when constructing new pointers, references and other composite types was building new types that weakly referred to their sub-types; for instance, a pointer type has a weak reference on its pointed-type. That means the referred-to type must be 'own' by something else. That means that strip_typedef() needs to create types which lifetime is "long enough". This patch ensures that strip_typedef() returns a canonical type; and we are sure that a canonical type is live during the entire life time of the libabigail library itself. So that means strip_typedef can only be used after types have been canonicalized. To that end, this patch changes is_class_type() to make it not strip typedefs. That way, is_class_type() can be used even when canonicalized types are not yet available. The patch then introduces a new is_compatible_with_class_type() function that strips typedef. The code of type_size_changed() that wanted to strip typedefs is then adjusted to use this new is_compatible_with_class_type() instead. * include/abg-fwd.h (is_compatible_with_class_type): Declare new function. (canonicalize): Move the declaration here, from ... * include/abg-ir.h (canonicalize): ... here. * src/abg-ir.cc (strip_typedef): Assert that the input type is canonicalized. Make sure that weak references are on canonicalized types. Make sure that the returned type is a canonical one. (canonicalize): Make this return the canonical type that it has computed. * src/abg-comp-filter.cc (type_size_changed): Use the new is_compatible_with_class_type() function, instead of is_class_type().

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.
