* include/abg-comp-filter.h: New file.
* include/Makefile.am: Add the new include/abg-comp-filter.h to
the source distribution.
* include/abg-comparison.h (enum visiting_kind, diff_category): New enums.
(operator|): Declare new operator declaration for the new
visiting_kind enum.
(operator{|,^,&,~}): Declare new operator decl for the new
diff_category enum.
(diff_context::{get_allowed_category, set_allowed_category,
switch_categories_on, switch_categories_off, diff_filters,
add_diff_filter, maybe_apply_filters}): Declare new member functions.
(diff::{parent_, category_}): New members.
(diff::diff): Adjust.
(diff::{get_parent, set_parent, get_category, add_to_category,
is_filtered_out, to_be_reported}): New members.
(diff_node_visitor::{get_visiting_kind, set_visiting_kind}): New
members.
(diff_node_visitor::visit): Add a new flag to saying if the
visitor is being called in post or pre children traversing mode.
* src/abg-comparison.cc (operator|): Declare new operator
declaration for the new visiting_kind enum.
(operator{|,^,&,~}): Declare new operator decl for the new
diff_category enum.
(diff_context::priv::{allowed_category_, filters_}): New members.
(diff_context::diff_context): Add all known filters.
(diff_context::{get_allowed_category, set_allowed_category,
switch_categories_on, switch_categories_off, diff_filters,
add_diff_filter, maybe_apply_filters}): Define new member
functions.
(diff::{is_filtered_out, to_be_reported}): Define new members.
(*::report): Use the new diff::to_be_reported function.
(*::traverse): Adjust for pre/post visiting.
(var_diff::var_diff): Chain the type diff node to its parent.
({pointer_diff, reference_diff, qualified_type_diff,
typedef_diff}::underlying_type_diff): Chain the underlying type
diff node to its parent.
(enum_diff::enum_diff): Likewise.
(base_diff::underlying_class_diff): Likewise.
({class_diff, corpus_diff}::report): Do not report changed
(member) functions that have been filtered out. Rather report
that they have been filtered out.
({function_decl_diff, class_diff}::traverse): Chain underlying
type diff nodes to their parent.
(diff_node_visitor::visit): Add a new flag to saying if the
visitor is being called in post or pre children traversing mode.
Make sure to call the default diff::visit overload.
* src/abg-comp-filter.cc: New file.
* src/Makefile.am: Add the new abg-comp-filter.cc to the source
distribution.
* tools/bidiff.cc (options::show_harm{ful,less}_changes): New
