New Revision: 272544

URL: https://gcc.gnu.org/viewcvs?rev=272544&root=gcc&view=rev
Log:
	* omp-low.c (lower_rec_simd_input_clauses): Add rvar2 argument,
	create another "omp scan inscan exclusive" array if
	!ctx->scan_inclusive.
	(lower_rec_input_clauses): Handle exclusive scan inscan reductions.
	(lower_omp_scan): Likewise.
	* tree-vectorizer.h (struct _stmt_vec_info): Use 3-bit instead of
	2-bit bitfield for simd_lane_access_p member.
	* tree-vect-data-refs.c (vect_analyze_data_refs): Also handle
	aux == (void *)-4 as simd lane access.
	* tree-vect-stmts.c (check_scan_store): Handle exclusive scan.  Update
	comment with permutations to show the canonical permutation order.
	(vectorizable_scan_store): Handle exclusive scan.
	(vectorizable_store): Call vectorizable_scan_store even for
	STMT_VINFO_SIMD_LANE_ACCESS_P > 3.
