(get_class_context): ... here; speed up handling obviously useless speculations. (odr_type_warn_count, decl_warn_count): New structures. (final_warning_record): New structure. (final_warning_records): New static variable. (possible_polymorphic_call_targets): Cleanup handling of speculative info; do not build speculation when user do not care; record info about warnings when asked for. (add_decl_warning): New function. (type_warning_cmp): New function. (decl_warning_cmp): New function. (ipa_devirt): Handle -Wsuggest-final-methods and -Wsuggest-final-types. (gate): Enable pass when warnings are requested. * common.opt (Wsuggest-final-types, Wsuggest-final-methods): New options. * g++.dg/warn/Wsuggest-final.C: New testcase. * g++.dg/ipa/devirt-34.C: Fix. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@213518 138bc75d-0d04-0410-961f-82ee72b054a4
