	gcc/
	* gimplify.c (gimplify_scan_omp_clauses): No special handling for
	OMP_CLAUSE_TILE.
	(gimplify_adjust_omp_clauses): Don't delete TILE.
	(gimplify_omp_for): Deal with TILE.
	* internal-fn.c (expand_GOACC_TILE): New function.
	* internal-fn.def (GOACC_DIM_POS): Comment may be overly conservative.
	(GOACC_TILE): New.
	* omp-expand.c (struct oacc_collapse): Add tile and outer fields.
	(expand_oacc_collapse_init): Add LOC paramter.  Initialize tile
	element fields.
	(expand_oacc_collapse_vars): Add INNER parm, adjust for tiling,

	adjust OLF_DIM_BASE value.
	(struct omp_for_data): Add tiling field.
	* omp-low.c (scan_sharing_clauses): Allow OMP_CLAUSE_TILE.
	(lower_oacc_head_mark): Add OLF_TILE as appropriate.  Ensure 2 levels
	for auto loops.  Remove default auto determining, moved to

	(oacc_loop_fixed_partitions): Determine default auto, deal with TILE,
	dump partitioning.
	(oacc_loop_auto_partitions): Add outer_assign parm. Assign all but
	vector partitioning to outer loops.  Assign 2 partitions to loops
	when available. Add TILE handling.
	(oacc_loop_partition): Adjust oacc_loop_auto_partitions call.
