* doc/gty.texi ("Inheritance and GTY"): Make it clear that
to use autogenerated markers for a class-hierarchy, every class
must have a GTY marker.
* gengtype.h (struct type): Add linked list of subclasses to
the "s" member of the union.
(add_subclass): New decl.
* gengtype-state.c (read_state_struct_type): Set up subclass
linked list.
* gengtype.c (get_ultimate_base_class): New.
(add_subclass): New.
(new_structure): Set up subclass linked list.
(set_gc_used_type): Propagate usage information to subclasses.
(output_mangled_typename): Use get_ultimate_base_class.
(walk_subclasses): Use the subclass linked list, avoiding an
O(N^2) when writing out all types.
(walk_type): Issue an error if the base class is missing a tag,
rather than generating bogus C code. Add a gcc_unreachable
default case, in case people omit tags from concrete subclasses,
or get the values wrong.
(write_func_for_structure): Issue an error for subclasses for
which the base doesn't have a "desc", since otherwise the
autogenerated routines for the base would silently fail to visit
any subclass fields.
(write_root): Use get_ultimate_base_class, tweaking constness of
tp to match that function's signature.

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
