Subject: [PATCH v2 08/31] Convert auto-load.c to type-safe registry API
Date: Fri, 03 May 2019 23:12:00 -0000 [thread overview]
Message-ID: <20190503231231.8954-9-tom@tromey.com> (raw)
In-Reply-To: <20190503231231.8954-1-tom@tromey.com>
This changes auto-load.c to use the type-safe registry API. It also
changes a couple of types to "bool", removing uses of "FALSE".
2019-04-22 Tom Tromey <tom@tromey.com>
* auto-load.c (struct auto_load_pspace_info): Add destructor and
initializers.
<unsupported_script_warning_printed,
script_not_found_warning_printed>: Now bool.
(auto_load_pspace_data): Change type.
(~auto_load_pspace_info): Rename from
auto_load_pspace_data_cleanup.
(get_auto_load_pspace_data, init_loaded_scripts_info)
(clear_section_scripts, maybe_print_unsupported_script_warning)
(maybe_print_script_not_found_warning, _initialize_auto_load):
Update.
