Introduce compiled_regex, eliminate make_regfree_cleanup This patch replaces compile_rx_or_error and make_regfree_cleanup with a class that wraps a regex_t. gdb/ChangeLog: 2017-06-07 Pedro Alves <palves@redhat.com> * Makefile.in (SFILES): Add gdb_regex.c. (COMMON_OBS): Add gdb_regex.o. * ada-lang.c (ada_add_standard_exceptions) (ada_add_exceptions_from_frame, name_matches_regex) (ada_add_global_exceptions, ada_exceptions_list_1): Change regex parameter type to compiled_regex. Adjust. (ada_exceptions_list): Use compiled_regex. * break-catch-throw.c (exception_catchpoint::pattern): Now a std::unique_ptr<compiled_regex>. (exception_catchpoint::~exception_catchpoint): Remove regfree call. (check_status_exception_catchpoint): Adjust to use compiled_regex. (handle_gnu_v3_exceptions): Adjust to use compiled_regex. * breakpoint.c (solib_catchpoint::compiled): Now a std::unique_ptr<compiled_regex>. (solib_catchpoint::~solib_catchpoint): Remove regfree call. (check_status_catch_solib): Adjust to use compiled_regex. (add_solib_catchpoint): Adjust to use compiled_regex. * cli/cli-cmds.c (apropos_command): Use compiled_regex. * cli/cli-decode.c (apropos_cmd): Change regex parameter to compiled_regex reference. Adjust to use it. * cli/cli-decode.h: Remove struct re_pattern_buffer forward declaration. Include "gdb_regex.h". (apropos_cmd): Change regex parameter to compiled_regex reference. * gdb_regex.c: New file. * gdb_regex.h (make_regfree_cleanup, get_regcomp_error): Delete declarations. (class compiled_regex): New. * linux-tdep.c: Include "common/gdb_optional.h". (struct mapping_regexes): New, factored out from mapping_is_anonymous_p, and adjusted to use compiled_regex. (mapping_is_anonymous_p): Use mapping_regexes wrapped in a gdb::optional and remove cleanups. Adjust to compiled_regex. * probe.c: Include "common/gdb_optional.h". (collect_probes): Use compiled_regex and gdb::optional and remove cleanups. * skip.c: Include "common/gdb_optional.h". (skiplist_entry::compiled_function_regexp): Now a gdb::optional<compiled_regex>. (skiplist_entry::compiled_function_regexp_is_valid): Delete field. (free_skiplist_entry): Remove regfree call. (compile_skip_regexp, skip_rfunction_p): Adjust to use compiled_regex and gdb::optional. * symtab.c: Include "common/gdb_optional.h". (search_symbols): Use compiled_regex and gdb::optional. * utils.c (do_regfree_cleanup, make_regfree_cleanup) (get_regcomp_error, compile_rx_or_error): Delete. Some bits moved to gdb_regex.c.
