During structural (function) type comparison, computing the pretty
representation of the type at hand appears high on performance profiles,
especially when type canonicalization wasn't really effective.
This patch adds a type_base::get_cached_pretty_representation() and a
function_type::get_cached_name() to cache the pretty representation of
a type, as well as the function type name. This is way, the type
representation is computed just once and stored into a cache.
subsequent invocations of the function just look into the cache
instead of computing the representation again.
Note that we do this only for non-canonicalized types because these
types can still be modified, and so caching the representation of a
type that might be changed (and thus see its representation change)
leads to issue. So the representation of non-canonicalized types is
not cached.
* include/abg-ir.h (type_base::get_cached_pretty_representation):
Declare new function.
(function_type::get_cached_name): Likewise.
* src/abg-ir.cc (get_method_type_name): Use the new
type_base::get_cached_pretty_representation function.
(type_base::priv::{internal_cached_repr_, cached_repr_}): Add new
data members.
(function_type::priv::{internal_cached_name_, cached_name_}):
Likewise.
(type_base::get_cached_pretty_representation): Define new
function.
(function_type::get_cached_name): Likewise.
(type_base::get_canonical_type_for): Call
type_base::get_cached_pretty_representation here, so the internal
representation is cached right before canonicalization.
(function_type::{mark_as_being_compared, unmark_as_being_compared,
comparison_started}): Uset he new type_base::get_cached_name to
speed up function type name retrieval.
