772414848e Update tests/data/test-read-write/test27.xml 
After the preceding patch series to handle ABI corpora in which the
ODR is not applicable (and the inevitable fallouts) this patch updates
the reference output for the test-read-write test harness.

	* tests/data/test-read-write/test27.xml: Adjust.

9cb146a013 Bug 17340 - Support pointers and references to functions 
* include/abg-comparison.h (compute_diff_for_distinct_kinds): Take the
	first two arguments of type const type_or_decl_base_sptr instead.
	* include/abg-ir.h (translation_unit::get_function_types): Declare new
	method.
	(function_types): Declare new typedef.
	* src/abg-comparison.cc (compute_diff_for_types): Take the first two
	arguments of type const type_or_decl_base_sptr instead of a const
	decl_base_sptr.
	(try_to_diff): Likewise.
	(try_to_diff<class_decl>): Likewise.
	(try_to_diff_distinct_kinds): Likewise.
	(compute_diff_for_distinct_kinds): Likewise. Also remove a variant
	accepting arguments of type const type_base_sptr.
	* src/abg-dwarf-reader.cc (build_class_type_and_add_to_ir): Skip
	building a pointer if it points to the beginning of a vptr.
	(build_pointer_type_def): Declare utype_decl of type
	type_or_decl_base_sptr and adjust assignments to it accordingly.
	(build_function_type): New function definition.
	(build_function_decl): Call build_function_type instead of building
	an ftype manually.
	(build_ir_node_from_die): Amend case DW_TAG_subroutine_type with
	appropriate calls to build a function type.
	* src/abg-ir.cc (translation_unit::get_function_types): New method
	definition.
	({pointer,reference}_type_def::pointer_type_def): Expect that
	pointed_to might not have an accompanying declaration and set a type's
	name in this case as well.
	({pointer,reference}_type_def::get_qualified_name): Generate a
	qualified name even if the pointed-to type has no declaration.
	* src/abg-reader.cc (build_function_type): New function definition.
	(handle_element_node): Return a type_or_decl_base_sptr instead and
	try calling handle_function_type in addition to others.
	(handle_function_type): New function definition that calls
	build_function_type.
	(build_type): Try calling build_function_type as well.
	* src/abg-writer.cc (fn_shared_ptr_map): Declare new typedef.

	been recorded to emit by write_{pointer,reference}_type_def.

	a type to be emitted if type == function type.

	abixml format and unmark the type.
