	gcc/c/
	* c-typeck.c (handle_omp_array_sections_1): Add 'bool &non_contiguous'
	parameter, adjust recursive call site, add cases for allowing
	pointer based multi-dimensional arrays for OpenACC.
	(handle_omp_array_sections): Adjust handle_omp_array_sections_1 call,
	handle non-contiguous case to create dynamic array map.

	gcc/cp/
	* semantics.c (handle_omp_array_sections_1): Add 'bool &non_contiguous'
	parameter, adjust recursive call site, add cases for allowing
	pointer based multi-dimensional arrays for OpenACC.
	(handle_omp_array_sections): Adjust handle_omp_array_sections_1 call,
	handle non-contiguous case to create dynamic array map.

	gcc/
	* gimplify.c (gimplify_scan_omp_clauses): For dynamic array map kinds,
	make sure bias in each dimension are put into firstprivate variables.
	* tree-pretty-print.c (dump_omp_clauses): Add cases for printing
	GOMP_MAP_DYNAMIC_ARRAY map kinds.
	* omp-low.c (struct omp_context):
	Add 'hash_map<tree_operand_hash, tree> *dynamic_arrays' field, also
	added include of "tree-hash-traits.h".

	(new_omp_context): Add initialize of dynamic_arrays field.
	(delete_omp_context): Add delete of dynamic_arrays field.
	(scan_sharing_clauses): For dynamic array map kinds, check for
	supported dimension structure, and install dynamic array variable into
	current omp_context.
	(lower_omp_target): Add handling for dynamic array map kinds.
	(dynamic_array_lookup): New function.
	(dynamic_array_reference_start): Likewise.
	(scan_for_op): Likewise.
	(scan_for_reference): Likewise.
	(da_create_bias): Likewise.
	(da_dimension_peel): Likewise.
	(lower_omp_1): Add case to look for start of dynamic array reference,
	and handle bias adjustments for the code sequence.

	include/
	* gomp-constants.h (GOMP_MAP_FLAG_SPECIAL_3): Define.
	(enum gomp_map_kind): Add GOMP_MAP_DYNAMIC_ARRAY,

	libgomp/
	* target.c (struct da_dim): New struct declaration.
	(struct da_descr_type): Likewise.
	(struct da_info): Likewise.
	(gomp_dynamic_array_count_rows): New function.
	(gomp_dynamic_array_compute_info): Likewise.
	(gomp_dynamic_array_fill_rows_1): Likewise.
	(gomp_dynamic_array_fill_rows): Likewise.
	(gomp_dynamic_array_create_ptrblock): Likewise.
	(gomp_map_vars): Add code to handle dynamic array map kinds.
