From-SVN: r204152

	* 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.

From-SVN: r204148

	* doc/gty.texi (GTY Options): Add note about inheritance to
	description of desc and tag.
	(Inheritance and GTY): New.

From-SVN: r204147

	* gengtype-parse.c (opts_have): Drop "static" so that
	we can use this from gengtype.c.
	* gengtype.c (set_gc_used_type): Mark any base class as used;
	update field traversal to visit inherited fields.
	(output_mangled_typename):  Convert references to classes within
	an inheritance hierarchy to reference the ultimate base class,
	since only it will have gt_ functions.
	(get_string_option): New.
	(walk_subclasses): New.
	(walk_type): Treat GTY structs that have a "desc" as being the
	root of an inheritance hierarchy.  Generate a switch on it
	within the marking function which walks all subclasses, adding
	cases for them via walk_subclasses.  For subclasses, visit all
	fields of the type (including inherited ones).
	(write_func_for_structure): Don't write fns for subclasses, only
	for the ultimate base class within an inheritance hierarchy.
	Subclasses-marking will be handled by the base class marking
	functions.
	(write_types): Likewise.
	(write_local_func_for_structure): Likewise.
	(USED_BY_TYPED_GC_P): Emit allocators for subclasses that have
	a "tag" option (and are thus concrete subclasses).
	(write_root): Use the marker function for the ultimate base class.
	* gengtype.h (FOR_ALL_INHERITED_FIELDS): New.
	(opts_have): Add declaration.

	* lra-spills.c (lra_final_code_change): Remove useless move insns
	originated from moves of pseudos.

	* gcc.dg/vmx/gcc-bug-i.c: Add little endian variant.
	* gcc.dg/vmx/eg-5.c: Likewise.
