	PR fortran/20541
	* interface.c (gfc_compare_derived_types): Add comparison of
	the allocatable field.
	* intrinsic.c (add_subroutines): Add MOVE_ALLOC.
	* trans-expr.c (gfc_conv_aliased_arg, gfc_trans_subarray_assign,
	gfc_trans_subcomponent_assign, gfc_conv_string_parameter,
	gfc_trans_scalar_assign): Add extra arguments l_is_temp
	and r_is_var to references to latter function.
	(gfc_conv_function_call): Add enum for types of argument and
	an associated variable parm_kind. Deallocate components of
	INTENT(OUT) and non-variable arrays.
	(gfc_trans_subcomponent_assign): Add block to assign arrays
	to allocatable components.
	(gfc_trans_scalar_assign): Add block to handle assignments of
	derived types with allocatable components, using the above new
	arguments to control allocation/deallocation of memory and the
	copying of allocated arrays.
	* trans-array.c (gfc_array_allocate): Remove old identification 
	of pointer and replace with that of an allocatable array. Add
	nullify of structures with allocatable components. 
	(gfc_conv_array_initializer): Treat EXPR_NULL.
	(gfc_conv_array_parameter): Deallocate allocatable components
	of non-variable structures.
	(gfc_trans_dealloc_allocated): Use second argument of library
	deallocate to inhibit, without error, freeing NULL pointers.
	(get_full_array_size): New function to return the size of a
	full array.
	(gfc_duplicate_allocatable): New function to allocate and copy
	allocated data.
	(structure_alloc_comps): New recursive function to deallocate,
	nullify or copy allocatable components.
	(gfc_nullify_alloc_comp, gfc_deallocate_alloc_comp,
	gfc_copy_alloc_comp): New interface functions to call previous.
	(gfc_trans_deferred_array): Add the code to nullify allocatable
	components, when entering scope, and to deallocate them on
	leaving. Do not call gfc_trans_static_array_pointer and return
	for structures with allocatable components and default
	initializers.
	* symbol.c (gfc_set_component_attr): Set allocatable field.
	(gfc_get_component_attr): Set the allocatable attribute.
	* intrinsic.h : Prototype for gfc_check_move_alloc.
	* decl.c (build_struct): Apply TR15581 constraints for
	allocatable components.
	(variable_decl): Default initializer is always NULL for
	allocatable components.
	(match_attr_spec): Allow, or not, allocatable components,
	according to the standard in force.
	* trans-array.h : Prototypes for gfc_nullify_alloc_comp,
	gfc_deallocate_alloc_comp, gfc_copy_alloc_comp and
	gfc_duplicate_allocatable.
	* gfortran.texi : Add mention of TR15581 extensions.
	* gfortran.h : Add attribute alloc_comp, add
	gfc_components field allocatable and add the prototype
	for gfc_expr_to_initialize.
	* trans-stmt.c (generate_loop_for_temp_to_lhs,
	generate_loop_for_rhs_to_temp, gfc_trans_where_assign,
	gfc_trans_where_3): Add extra arguments to calls to
	gfc_trans_scalar_assign and set appropriately.
	(gfc_trans_allocate): Nullify allocatable components.
	(gfc_trans_deallocate): Deallocate to ultimate allocatable
	components but stop at ultimate pointer components.
	* module.c (mio_symbol_attribute, mio_symbol_attribute,
	mio_component): Add module support for allocatable
	components.
	* trans-types.c (gfc_get_derived_type): Treat allocatable
	components.
	* trans.h : Add two boolean arguments to
	gfc_trans_scalar_assign.
	* resolve.c (resolve_structure_cons): Check conformance of
	constructor element and the component.
	(resolve_allocate_expr): Add expression to nullify the
	constructor expression for allocatable components.
	(resolve_transfer): Inhibit I/O of derived types with
	allocatable components.
	(resolve_fl_derived): Skip check of bounds of allocatable
	components.
	* trans-decl.c (gfc_get_symbol_decl): Add derived types
	with allocatable components to deferred variable.
	(gfc_trans_deferred_vars): Make calls for derived types
	with allocatable components to gfc_trans_deferred_array.
	(gfc_generate_function_code): Nullify allocatable
	component function result on entry.
	* parse.c (parse_derived): Set symbol attr.allocatable if
	allocatable components are present.
	* check.c (gfc_check_allocated): Enforce attr.allocatable
	for intrinsic arguments.
	(gfc_check_move_alloc): Check arguments of move_alloc.
	* primary.c (gfc_variable_attr): Set allocatable attribute.
	* intrinsic.texi : Add index entry and section for
	for move_alloc.

	PR fortran/29115
	* resolve.c (resolve_structure_cons): It is an error if the
	pointer component elements of a derived type constructor are
	not pointer or target.


	PR fortran/29211
	* trans-stmt.c (generate_loop_for_temp_to_lhs,
	generate_loop_for_rhs_to_temp): Provide a string length for
	the temporary by copying that of the other side of the scalar
	assignment.
