	* gcc/lto/lto.c (enum DWARF2_class): Split DW_cl_constant into
	DW_cl_uconstant and DW_cl_sconstant for explicitly unsigned and
	signed constants.  Re-number the enumerators.
	(struct DWARF2_form_data): Replace constant field with uconstant
	and sconstant, for explicitly unsigned and signed constants.
	(struct lto_context): Remove type field.  Add language and
	parentdata fields.
	(lto_file_corrupt_error): Add ATTRIBUTE_NORETURN.
	(lto_abi_mismatch_error): Likewise.
	(lto_read_uleb128): Fix to assemble bytes in the correct order.
	(lto_read_sleb128): New.
	(lto_read_form): Make it know about some more attributes.  Make it
	understand DW_FORM_sdata and DW_FORM_udata.
	(attribute_value_as_int): New.  Change places throughout the file
	formerly accessing attribute values expected to be host integers
	as attr_data.u.constant to call this function instead.
	(make_signed_host_wide_int): New.
	(attribute_value_as_constant): New function for use when the attribute
	value represents a target integer constant of a given type.
	(lto_find_integral_type): New.
	(lto_read_referenced_type_DIE): Don't mess with type in context.
	(lto_read_compile_unit_DIE): Return tree instead of void.  Set the
	language in the context.
	(lto_read_array_type_DIE): New.
	(lto_read_enumeration_type_DIE): New.
	(lto_read_enumerator_DIE): New.
	(lto_read_variable_formal_parameter_constant_DIE): Return the decl
	instead of void.
	(lto_read_pointer_type_DIE): Return the type instead of void.
	(lto_read_subrange_type_DIE): New.
	(lto_read_base_type_DIE): Return the type instead of void.  Also,
	GCC generates unnamed base_type DIEs, so do something sensible if
	we get one.
	(lto_read_DIE): Change type to return the tree value constructed from
	reading the DIE.  Make the boolean "more" flag a parameter instead.
	Updated all callers.  Make it know about the readers for array_type,
	enumeration_type, and subrange_type, and enumerator DIEs.
	(lto_collect_child_DIEs): New.
	(lto_file_read): Don't initialize type in context.  Do initialize
	parentdata instead.
	
	* gcc/lto/lto-tree.h (lto_global_var_decls): Declare.

	* gcc/lto/lto.h: Include tree.h.
	* gcc/lto/Make-lang.in (LTO_H): Note dependency on TREE_H here.

	* gcc/lto/lto-symtab.c (lto_global_var_decls): Define.
	(lto_symtab_merge_var): Record decls in lto_global_var_decls.

	* gcc/lto/lto-lang.c (lto_write_globals): New.
	(lto_init): Initialize lto_global_var_decls.
	LANG_HOOKS_WRITE_GLOBALS: Define to point at lto_write_globals.
