Hello All,
[I don't know if this discussion belongs to gcc@ or gcc-patches@ so I'm
sending it on gcc@ since I don't propose or discuss any code yet]
My understanding was that most plugins people are aware that somehow
some plugins would need to have static GTY-ed roots for the GGC machinery.
So it seems to me that we'll need :
1. The ability to run gengtype in a special mode for plugins, on the
source code of the plugin. to generate the gt-*.h files included by the
source code of the plugin. This would require a patch to gengtype.
2. The ability to handle, very probably using dlsym, or perhaps by
having a gcc_plugin_register_gty_table function called from the plugin
initialization routine, to plug the generated root tables (an array of
struct ggc_root_tab, which is defined in the generated gt-*.h files) of
the plugin into the GGC machinery. This would require a short patch to
ggc-common.c or similar ggc-*.c files.
Did I miss anything?
Regards.
PS. This is not an April Fool joke! I am quit serious about extra GTY-ed
roots. It is for me an essential & required condition to perhaps
transform the MELT branch into a mega-plugin.
