- Subject: adding a PLUGIN_PARSED_UNIT event
Hello All,
The attached patch, to trunk rev 152849, add a PLUGIN_PARSED_UNIT event,
invoked at start of cgraph_finalize_compilation_unit after all the
compilation unit has been parsed.
My intuition is that we should better provide a little more hooks,
especially at a such higher level. Doing everything only in passes is
not practical (and was the reason to add stuff like PLUGIN_FINISH_UNIT
gcc/ChangeLog:
2009-10-15 Basile Starynkevitch <basile@starynkevitch.net>
* doc/plugins.texi (Plugin callbacks): added PLUGIN_PARSED_UNIT.
* cgraphunit.c (cgraph_finalize_compilation_unit): Added
invocation of PLUGIN_PARSED_UNIT callbacks.
* gcc-plugin.h: Added PLUGIN_PARSED_UNIT.
* plugin.c (plugin_event_name): Added PLUGIN_PARSED_UNIT.
(invoke_plugin_callbacks): ditto.
I am bootstrapping it right now on x86_64-unknown-gnu-linux for c&c++
Comments are welcome.
I also believe that we should have plugin hooks for builtins.
Regards.
