gty.texi (Options): Document the mark_hook option to GTY.
2007-01-19 Basile Starynkevitch <basile@starynkevitch.net>
* gcc/doc/gty.texi (Options): Document the mark_hook option to
GTY.
* gcc/gengtype.c (write_types_data, write_func_for_structure,
write_types, ggc_wtd, pch_wtd): Added skip_hooks to
write_types_data, ggc_wtd, pch_wtd for mark_hook.
(walk_type, write_func_for_structure): Generate the mark_hook if
needed.
* MAINTAINERS: added myself (Basile Starynkevitch) to write after
approval.
