@section Interacting with the GCC Garbage Collector
Some plugins may want to be informed when GGC (the GCC Garbage
Collector) is running. They can register callbacks for the
@code{PLUGIN_GGC_START} and @code{PLUGIN_GGC_END} events (for which
the callback is called with a null @code{gcc_data}) to be notified of
the start or end of the GCC garbage collection.
Some plugins may need to have GGC mark additional data. This can be
done by registering a callback (called with a null @code{gcc_data})
for the @code{PLUGIN_GGC_MARKING} event. Such callbacks can call the
@code{ggc_set_mark} routine, preferably thru the @code{ggc_mark} macro
(and conversly, these routines should usually not be used in plugins
outside of the @code{PLUGIN_GGC_MARKING} event).
Some plugins may need to add extra GGC root tables, e.g. to handle
their own @code{GTY}-ed data. This can be done with the
@code{PLUGIN_REGISTER_GGC_ROOTS} pseudo-event with a null callback and the
extra root table as @code{user_data}.
You should understand the details of memory management inside GCC
before using @code{PLUGIN_GGC_MARKING} or
@code{PLUGIN_REGISTER_GGC_ROOTS}.
@section Giving information about a plugin
A plugin should give some information to the user about itself. This
uses the following structure:
@smallexample
struct plugin_info
@{
const char *version;
const char *help;
@};
@end smallexample
Such a structure is passed as the @code{user_data} by the plugin's
init routine using @code{register_callback} with the
@code{PLUGIN_INFO} pseudo-event and a null callback.
@section Registering custom attributes
For analysis purposes it is useful to be able to add custom attributes.
