* include/abg-comp-filter.h (has_harmless_name_change): New function declaration. * include/abg-comparison.h (diff_category::DECL_NAME_CHANGE_CATEGORY): Renamed this into HARMLESS_DECL_NAME_CHANGE_CATEGORY. (diff_category::EVERYTHING_CATEGORY): Update. * include/abg-fwd.h (is_enum): New function declaration. (is_var_decl): Return the shared_ptr<var_decl> rather than a bool. (is_data_member): New overload that takes a shared_ptr<decl_base>. * src/abg-comp-filter.cc (decl_name_changed): Consider the qualified name here. (has_harmless_name_change): Define new function declaration. (harmless_filter::visit): Use the new has_harmless_name_change function. * src/abg-comparison.cc (represent) (report_name_size_and_alignment_changes, enum_diff::report) (typedef_diff::report, is_data_member): Use the new filtering::has_harmless_name_change function to simplify logic of emitting the name change related diff * tools/bidiff.cc (set_diff_context_from_opts): Adjust DECL_NAME_CHANGE_CATEGORY -> HARMLESS_DECL_NAME_CHANGE_CATEGORY. * src/abg-ir.cc (is_data_member, is_enum): New function definitions. (is_var_decl): Return the var_decl_sptr rather than just a bool. * tests/data/test-diff-filter/test13-report.txt: Adjust. * tests/data/test-diff-filter/test6-report.txt: Adjust.
