During canonicalization of a type T, when T is structurally compared
to an already canonicalized type C, it can happen that
non-canonicalized sub-types of T are structurally compared again and
again to canonicalized sub-types of C.
This patch introduces a new optimization or those cases: on-the-fly
type canonicalized.
That means, if a not-yet-canonicalized sub-type S of the type T being
canonicalized structurally compares equal to a canonicalized sub-type,
then the canonical type of S is said to be the canonical type of the
canonicalized sub-type. So sub-type S is canonicalized, on-the-fly,
during canonicalization of type T.
This considerably speeds up the canonicalization process while doing
"abidiff vmlinux vmlinux". It goes from taking forever to taking 45
seconds on a non-optimized build.
* include/abg-ir.h (environment::do_on_the_fly_canonicalization):
Declare new member functions.
({type_base, function_type}::priv_): Make this public so that
static non-member functions defined in abg-ir.cc can access it.
* src/abg-ir.cc
(environment::priv::do_on_the_fly_canonicalization_): New data
member.
(environment::priv::priv): Initialize it.
(environment::do_on_the_fly_canonicalization): Define new member
functions.
(type_base::get_canonical_type_for): Trigger on-the-fly
canonicalization during comparison of the type being canonicalized
and an already canonicalized type.
(types_are_being_compared, maybe_propagate_canonical_type): Define
new static functions.
(equals): In overloads for class_decl and function_type, call
maybe_propagate_canonical_type when the two types compare equal.
* tests/data/test-diff-pkg/tbb-4.1-9.20130314.fc22.x86_64--tbb-4.3-3.20141204.fc23.x86_64-report-0.txt:
Adjust.
* tests/data/test-read-dwarf/test9-pr18818-clang.so.abi: Likewise.

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.
