New Revision: 226438

URL: https://gcc.gnu.org/viewcvs?rev=226438&root=gcc&view=rev
Log:
	* libgomp.h (enum gomp_map_vars_kind): New.
	(gomp_map_vars): Change type of the argument from bool to enum
	gomp_map_vars_kind.
	* oacc-mem.c (acc_map_data, present_create_copy,
	gomp_acc_insert_pointer): Pass GOMP_MAP_VARS_OPENACC instead of false to
	gomp_map_vars.
	* oacc-parallel.c (GOACC_parallel, GOACC_data_start): Likewise.
	* target.c (gomp_map_vars_existing): Fix target address for 'always to'
	array sections.
	(gomp_map_vars): Change type of the argument from bool to enum
	gomp_map_vars_kind, fixup its usage.  Set tgt->refcount to 0 if called
	from GOMP_target_enter_exit_data.  Free tgt if called from
	GOMP_target_enter_exit_data and nothing has been mapped.
	(gomp_unmap_vars): Decrement k->refcount when it is 1 and
	k->async_refcount is 0.
	(gomp_offload_image_to_device): Set tgt's refcount to infinity.
	(GOMP_target, GOMP_target_41): Pass GOMP_MAP_VARS_TARGET instead of true
	to gomp_map_vars.
	(gomp_target_data_fallback, GOMP_target_data, GOMP_target_data_41): Pass
	GOMP_MAP_VARS_DATA instead of false to gomp_map_vars.
	(gomp_exit_data): New static function.
	(GOMP_target_enter_exit_data): Support mapping/unmapping.
	* testsuite/libgomp.c/target-11.c: Extend for testing 'always to' array
	sections.
	* testsuite/libgomp.c/target-20.c: New test.
