2012-04-01  Caroline Tice <cmtice@google.com>

	* gcc/tree.h (save_vtable_map_decl): New extern function decl.
	* gcc/cp/Make-lang.in (CXX_AND_OBJCXX_OBJS): Add
	vtable-class-hierarchy.o to list of C++ language-specific object
	files.
	(vtable-class-hierarchy.o): Add rule for building
	vtable-class-hierarchy.o
	* gcc/cp/decl2.c (start_objects): Add third parameter, for
	function name extension.
	(generate_ctor_or_dtor_function): Add empty string as third
	argument to calls to start_objects.
	(cp_process_pending_declarations): Add code to generate special
	constructor function with high initialization priority for special
	vtable verification calls, if the flag_vtable_verify is set.
	* gcc/cp/parser.c (cp_parser_class_specifier_1): If
	flag_vtable_verify is set and the current class has base classes,
	generate the
	*.vtable_map variables for any base classes that don't already
	have it and add the base class/derived class pair to the class
	hierarchy information.
	* gcc/cp/vtable-class-hierarchy.c: New file.
	* gcc/cp/mangle.c (get_mangled_id): New function. Copied from PPH
	work of Lawrence Crowl and Diego Novillo.
	(mangle_decl): Call get_mangled_id rather than doing work directly
	here. Copied from PPH work of Lawrence Crowl ande Diego Novillo.
	* gcc/cp/cp-tree.h (get_mangled_id): New function decl.
	(register_class_hierarchy_information): New function decl.
	(update_class_hierarchy_information): New function decl.
	(vtable_find_map_decl):  New function decl.
	* gcc/temp-libgcc.cc: New file.
	* gcc/tree-vtable-verify.cc: (cp/cp-tree.h): New include statement.
	(build_vtable_verify_fndecl):  Renamed function (eliminated 's' from
	the end).
	(my_build1):  New function.
	(my_get_vtbl_decl_for_binfo): Renamed function (old name was
	get_vtbl_decl_for_binfo).
	(vtable_var_decl_array): New global variable.
	(vtable_var_decl_array_max): New global variable.
	(vtable_var_decl_array_entries): New global variable.
	(find_vtable_map_decl): New function.
	(save_vtable_map_decl): New function.
	(verify_bb_vtables): Fix a few bugs, and add some debugging parameters
	for calls to __VerifyVtablePointer.
	(build_vtable_verify_fndecl): Remove unnecessary variables.
	* gcc/config/i386/i386.c (ix86_vtable_security_code_end):  Modify to
	output dummy versions of __VLTChangePermission and __VLTRegisterPair
	in addition to __VerifyVtablePointer. Also add code to generate
	x86_64 assembly, instead of i386, if it's appropriate.
