I wanted to pass a lambda to iterate_over_symtabs (see following patch), so I converted it to function_view, and then the rest is cascaded from that. This gets rid of a bunch of single-use callback functions and corresponding manually managed callback capture types (add_partial_datum, search_symbols_data, etc.) in favor of letting the compiler generate them for us by using lambdas with a capture. In a couple cases, it was more natural to convert the existing function callbacks to function objects (i.e., operator(), e.g., decode_compound_collector). gdb/ChangeLog: 2017-02-23 Pedro Alves <palves@redhat.com> * ada-lang.c: Include "common/function-view.h". (ada_iterate_over_symbols): Adjust to use function_view as callback type. (struct add_partial_datum, ada_complete_symbol_matcher): Delete. (ada_make_symbol_completion_list): Use a lambda. (ada_exc_search_name_matches): Delete. (name_matches_regex): New. (ada_add_global_exceptions): Use a lambda and name_matches_regex. * compile/compile-c-support.c: Include "common/function-view.h". (print_one_macro): Change prototype to accept a ui_file pointer. (write_macro_definitions): Use a lambda. * dwarf2read.c: Include "common/function-view.h". (dw2_map_expand_apply, dw2_map_symtabs_matching_filename) (dw2_expand_symtabs_matching): Adjust to use function_view as callback type. * language.h: Include "common/function-view.h". (struct language_defn) <la_iterate_over_symbols>: Adjust to use function_view as callback type. (LA_ITERATE_OVER_SYMBOLS): Remove DATA parameter. * linespec.c: Include "common/function-view.h".
