This is an initial implementation of the support for incomplete, also
known as forward-declared, enum types. I've not made any attempt to
refactor or share logic with the struct/union code.
* include/abg-comp-filter.h (has_decl_only_def_change) : Declare
New function.
* src/abg-comp-filter.cc (there_is_a_decl_only_enum): Define new
static function and ...
(type_size_changed): ... use it here.
(has_decl_only_def_change): Define new function and ...
(categorize_harm{less, ful}_diff_node): ... use it here.
* include/abg-fwd.h (enums_type, decl_base_wptr): Declare new
typedefs.
(look_through_decl_only_class): Declare new overload for
class_or_union*.
(is_compatible_with_enum_type, is_compatible_with_enum_type)
(look_through_decl_only, lookup_enum_types, lookup_enum_types):
Declare new functions.
* include/abg-ir.h (decl_base::{get_is_declaration_only,
set_is_declaration_only, set_definition_of_declaration,
get_definition_of_declaration,
get_naked_definition_of_declaration}): Declare new member
functions. They were moved here from the class_or_union class.
(class_or_union::{get_earlier_declaration,
set_earlier_declaration, get_definition_of_declaration,
set_definition_of_declaration,
get_naked_definition_of_declaration, get_is_declaration_only,
set_is_declaration_only}): Remove these member functions.
* src/abg-ir.cc (decl_base::priv::{declaration_,
definition_of_declaration_, naked_definition_of_declaration_,
is_declaration_only_}): Define data members. Moved here from
class_or_union.
(decl_base::priv::priv): Adjust to initialize the new data
members.
(decl_base::{get_earlier_declaration, set_earlier_declaration,
get_definition_of_declaration,
get_naked_definition_of_declaration, get_is_declaration_only,
set_is_declaration_only, set_definition_of_declaration}): Define
member functions.
(operator|): In the overload for (change_kind, change_kind),
adjust the return type of the call to
decl_base::get_definition_of_declaration.
(look_through_decl_only): Define new function.
(look_through_decl_only_class): Adjust.
(look_through_decl_only_enum): Likewise.
(maybe_update_types_lookup_map<class_decl>): Adjust return type of
call to decl_base::get_definition_of_declaration.
(types_defined_same_linux_kernel_corpus_public): Use
look_through_decl_only_class rather than open coding it.
(class_or_union::priv::{declaration_, definition_of_declaration_,
naked_definition_of_declaration_, is_declaration_only_}): Remove
these data members. They are now carried by decl_base::priv.
(class_or_union::{g,s}et_alignment_in_bits): Adjust.
(class_or_union::{g,s}et_size_in_bits): Likewise.
(class_or_union::operator==): Likewise.
(equals): Adjust the overload for class_or_union.
(is_compatible_with_enum_type)
* src/abg-comparison.cc (try_to_diff<class_decl>): Adjust the
return type of decl_base::get_definition_of_declaration.
(leaf_diff_node_marker_visitor::visit_begin): Use
filtering::has_decl_only_def_change rather than
filtering::has_class_decl_only_def_change. Decl-only changes to
enums (or any other type really) will thus not be recorded as leaf
changes.
* src/abg-dwarf-reader.cc (get_scope_for_die): Adjust return type
of decl_base::get_definition_of_declaration.
* src/abg-default-reporter.cc (default_reporter::report): Report
enum decl-only <-> definition changes.
* src/abg-hash.cc (class_or_union:#️⃣:operator()): In the
overload for class_or_union& adjust the return type for
decl_base::get_definition_of_declaration.
