While emitting an abixml output for a corpus_group representing the
KMI of a Linux kernel tree, profiling shows that during comparison of
class types, calling class_decl::get_definition_of_declaration is a
hotspot. Especially, the fact the function returns a shared pointer
that has to be "handled" shows up in the profile.
This patch introduces a
class_decl::get_naked_definition_of_declaration that returns a
pointer. Not a shared pointer.
The patch then uses that get_naked_definition_of_declaration function
in the comparison code for class_decl.
The patch also uses get_naked_canonical_type instead of
get_canonical_type when comparing a bunch of other types.
This makes things a little bit faster when compiled without
optimization between 2% and 5%.
* include/abg-ir.h
(class_or_union::get_naked_definition_of_declaration): Declare a
new member function.
(class_decl::get_naked_definition_of_declaration): Likewise.
* src/abg-ir.cc ({type_decl, qualified_type_def,
array_type_def, enum_type_decl}::operator==): Use the
get_naked_canonical_type and get_naked.
(class_or_union::priv::naked_definition_of_declaration_): Define
new data member.
(class_or_union::priv::priv): Adjust to initialize the new data
member.
(class_or_union::get_naked_definition_of_declaration): Define new
member function.
({class_or_union, class_decl}::operator==): Use the new
get_naked_definition_of_declaration instead of
get_definition_of_declaration.
(equals): In the overload for class_or_union, do the same.
(class_decl::get_naked_definition_of_declaration): Define new
member function.
(hash_type_or_decl): Likewise.
