Simplify handling of auto-loaded objfile scripts.
.debug_gdb_scripts was always intended to handle more than just python,
thus the rightful home for the code that processes it is not in py-foo.c.
This is just a cleanup to move the code to a better place.
This also simplifies the handling of the ${objfile}-${suffix} auto-loaded
scripts. There's no need for each of the the handlers to do is-safe-to-load
checking, or call maybe_add_script. Doing it in the caller removes the
duplication.
* auto-load.h (script_language): New members name, auto_load_enabled.
Add missing comments on struct members.
(auto_load_objfile_script): Delete.
* auto-load.c: #include "cli/cli-cmds.h".
(auto_load_gdb_scripts_enabled): New function.
(script_language_gdb): Update, add new members.
(source_gdb_script_for_objfile): Simplify, auto-load safe-checking
and call to maybe_add_script moved to caller.
(auto_load_objfile_script_1): Auto-load safe-checking and
call to maybe_add_script moved here.
(auto_load_objfile_script): Make static. Early exit if support for
scripting language hasn't been compiled in, or auto-loading has been
disabled.
(source_section_scripts): Argument "source_name" renamed to
"section_name". All uses updated. Replace uses of AUTO_SECTION_NAME
with section_name. Skip loading script if support for scripting
language hasn't been compiled in, or auto-loading has been disabled.
Call language->source_script_for_objfile instead of calling
source_python_script_for_objfile directly.
(load_auto_scripts_for_objfile): Update.
* python/py-auto-load.c: Delete #include "cli/cli-cmds.h".
(gdbpy_load_auto_script_for_objfile): Delete.
(auto_load_python_scripts_enabled): New function.
(script_language_python): Update, add new members.
(gdbpy_script_language_defn): New function.
* python/python.h (gdbpy_load_auto_scripts_for_objfile): Delete.
(gdbpy_script_language_defn): Declare.
* auto-load.c (AUTO_SECTION_NAME): Moved here and renamed from
py-auto-load.c, GDBPY_AUTO_SECTION_NAME.
(source_section_scripts): Moved here from py-auto-load.c.
(auto_load_section_scripts): Ditto.
* python/py-auto-load.c (GDBPY_AUTO_SECTION_NAME): Moved to
auto-load.c, renamed AUTO_SECTION_NAME.
(source_section_scripts, auto_load_section_scripts): Moved to
auto-load.c.
