@chapter Plugins
|

@cindex Plugins
|
||||
|
||||
@section Loading Plugins
|
||||
|
||||
Plugins are supported on platforms that support @option{-ld
|
||||
-rdynamic}. They are loaded by the compiler using @code{dlopen}
|
||||
and invoked at pre-determined locations in the compilation
|
||||
process.
|
||||
|
||||
Plugins are loaded with
|
||||
|
||||
@option{-fplugin=/path/to/NAME.so} @option{-fplugin-arg-NAME-<key1>[=<value1>]}
|
||||
|
||||
The plugin arguments are parsed by GCC and passed to respective
|
||||
plugins as key-value pairs. Multiple plugins can be invoked by
|
||||
specifying multiple @option{-fplugin} arguments.
|
||||
|
||||
|
||||
@section Plugin API
|
||||
|
||||
Plugins are activated by the compiler at specific events as defined in
|
||||
@file{gcc-plugin.h}. For each event of interest, the plugin should
|
||||
call @code{register_callback} specifying the name of the event and
|
||||
address of the callback function that will handle that event.
|
||||
|
||||
@subsection Plugin initialization
|
||||
|
||||
Every plugin should export a function called @code{plugin_init} that
|
||||
is called right after the plugin is loaded. This function is
|
||||
responsible for registering all the callbacks required by the plugin
|
||||
and do any other required initialization.
|
||||
|
||||
This function is called from @code{compile_file} right before invoking
|
||||
the parser. The arguments to @code{plugin_init} are:
|
||||
|
||||
@itemize @bullet
|
||||
@item @code{plugin_name}: Name of the plugin.
|
||||
@item @code{argc}: Number of arguments specified with @option{-fplugin-arg-...}.
|
||||
@item @code{argv}: Array of @code{argc} key-value pairs.
|
||||
@end itemize
|
||||
|
||||
If initialization fails, @code{plugin_init} must return a non-zero
|
||||
value. Otherwise, it should return 0.
|
||||
|
||||
@subsection Plugin callbacks
|
||||
|
||||
Callback functions have the following prototype:
|
||||
|
||||
@smallexample
|
||||
/* The prototype for a plugin callback function.
|
||||
gcc_data - event-specific data provided by GCC
|
||||
user_data - plugin-specific data provided by the plug-in. */
|
||||
typedef void (*plugin_callback_func)(void *gcc_data, void *user_data);
|
||||
@end smallexample
|
||||
|
||||
Callbacks can be invoked at the following pre-determined events:
|
||||
|
||||
|
||||
@smallexample
|
||||
enum plugin_event
|
||||
@{
|
||||
PLUGIN_PASS_MANAGER_SETUP, /* To hook into pass manager. */
|
||||
PLUGIN_FINISH_TYPE, /* After finishing parsing a type. */
|
||||
PLUGIN_FINISH_UNIT, /* Useful for summary processing. */
|
||||
PLUGIN_CXX_CP_PRE_GENERICIZE, /* Allows to see low level AST in C++ FE. */
|
||||
PLUGIN_FINISH, /* Called before GCC exits. */
|
||||
PLUGIN_EVENT_LAST /* Dummy event used for indexing callback
|
||||
array. */
|
||||
@};
|
||||
@end smallexample
|
||||
|
||||
To register a callback, the plugin calls @code{register_callback} with the arguments:
|
||||
|
||||
@itemize
|
||||
@item @code{char *name}: Plugin name.
|
||||
@item @code{enum plugin_event event}: The event code.
|
||||
@item @code{plugin_callback_func callback}: The function that handles @code{event}.
|
||||
@item @code{void *user_data}: Pointer to plugin-specific data.
|
||||
@end itemize
|
||||
|
||||
|
||||
@section Interacting with the pass manager
|
||||
|
||||
There needs to be a way to add/reorder/remove passes dynamically. This
|
||||
is useful for both analysis plugins (plugging in after a certain pass
|
||||
such as CFG or an IPA pass) and optimization plugins.
|
||||
|
||||
Basic support for inserting new passes or replacing existing passes is
|
||||
provided. A plugin registers a new pass with GCC by calling
|
||||
@code{register_callback} with the @code{PLUGIN_PASS_MANAGER_SETUP}
|
||||
event and a pointer to a @code{struct plugin_pass} object defined as follows
|
||||
|
||||
@smallexample
|
||||
enum pass_positioning_ops
|
||||
@{
|
||||
PASS_POS_INSERT_AFTER, // Insert after the reference pass.
|
||||
PASS_POS_INSERT_BEFORE, // Insert before the reference pass.
|
||||
PASS_POS_REPLACE // Replace the reference pass.
|
||||
@};
|
||||
|
||||
struct plugin_pass
|
||||
@{
|
||||
struct opt_pass *pass; /* New pass provided by the plugin. */
|
||||
const char *reference_pass_name; /* Name of the reference pass for hooking
|
||||

|
||||
int ref_pass_instance_number; /* Insert the pass at the specified
|
||||
instance number of the reference pass. */
|
||||
/* Do it for every instance if it is 0. */
|
||||
enum pass_positioning_ops pos_op; /* how to insert the new pass. */
|
||||
@};
|
||||
|
||||
|
||||
/* Sample plugin code that registers a new pass. */
|
||||
int
|
||||
plugin_init (const char *plugin_name, int argc, struct plugin_argument *argv)
|
||||
@{
|
||||
struct plugin_pass pass_info;
|
||||
|
||||
...

|
||||

|
||||
|
