gcc/fortran/ChangeLog:

2016-09-19  Andre Vehreschild  <vehre@gcc.gnu.org>

	* expr.c (gfc_check_assign): Added flag to control whether datatype
	conversion is allowed.
	* gfortran.h: Added caf-token-tree to gfc_component.  Changed
	prototypes mostly to add whether datatype conversion is allowed.
	* gfortran.texi: Added documentation for the caf_reference_t and the
	caf_*_by_ref function.
	* primary.c (caf_variable_attr): Similar to gfc_variable_attr but
	focused on the needs of coarrays.
	(gfc_caf_attr): Same.
	* resolve.c (resolve_ordinary_assign): Set the conversion allowed
	flag when not in a coarray.
	* trans-array.c (gfc_array_init_size): Moved setting of array
	descriptor's datatype before the alloc, because caf_register needs it.
	(gfc_array_allocate): Changed notion of whether an array is a coarray.
	(gfc_array_deallocate): Same.
	(gfc_alloc_allocatable_for_assignment): Added setting of coarray's

	register to mimmick a realloc for coarrays.
	* trans-decl.c (gfc_build_builtin_function_decls): Corrected signatures
	of old caf-functions and added signature definitions of the _by_ref
	ones.
	(generate_coarray_sym_init): Adapted to new caf_register signature.
	* trans-expr.c (gfc_conv_scalar_to_descriptor): Make sure a constant
	is translated to an lvalue expression before use in an array
	descriptor.
	(gfc_get_ultimate_alloc_ptr_comps_caf_token): New function.  Get the
	last allocatable component's coarray token.
	(gfc_get_tree_for_caf_expr): For top-level object get the coarray
	token and check for unsupported features.
	(gfc_get_caf_token_offset): Getting the offset might procude new
	statements, which now are stored in the pre and post of the current se.
	(gfc_caf_get_image_index): For this image return a call to
	caf_this_image.
	(expr_may_alias_variables): Check that the result is set for testing
	its properties.

	coarray components.
	(gfc_trans_assignment_1): Rewrite an assign to a coarray object to
	be a sendget.
	* trans-intrinsic.c (conv_caf_vector_subscript_elem): Corrected
	wrong comment.
	(compute_component_offset): Compute the correct offset a structure
	member.
	(conv_expr_ref_to_caf_ref): Convert to a chain of refs into
	caf_references.

	(conv_caf_send): Call caf_*_by_ref for coarrays that need
	reallocation.
	(gfc_conv_intrinsic_function): Adapted to new signuature of the caf
	drivers.
	(conv_intrinsic_atomic_op): Add pre and post statements correctly.
	(conv_intrinsic_atomic_ref): Same.
	(conv_intrinsic_atomic_cas): Same.
	(conv_intrinsic_event_query): Same.
	* trans-stmt.c (gfc_trans_lock_unlock): Same.
	(gfc_trans_event_post_wait): Same.
	(gfc_trans_allocate): Support allocation of allocatable coarrays.
	(gfc_trans_deallocate): And there deallocation.
	* trans-types.c (gfc_typenode_for_spec): Added flag to control whether
	a component is part of coarray.  When so, then add space to store a
	coarray token.
	(gfc_build_array_type): Same.
	(gfc_get_array_descriptor_base): Same.
	(gfc_get_array_type_bounds): Same.
