2012-06-01  Richard Guenther  <rguenther@suse.de>

	* tree-loop-distribution.c (enum partition_kind): New enum.
	(struct partition_s): Add kind and main_stmt members.
	(partition_alloc): Initialize kind to PKIND_NORMAL.
	(partition_builtin_p): New function.
	(copy_loop_before): Remove failure path and assert instead.
	(generate_loops_for_partition): Likewise.
	(generate_memset_zero): Fold into ...
	(generate_memset_builtin): ... this.
	(classify_partition): New function with code from
	can_generate_builtin and generate_builtin.
	(generate_builtin): Remove.
	(can_generate_builtin): Likewise.
	(fuse_partitions_with_similar_memory_accesses): Call
	partition_builtin_p instead of can_generate_builtin.
	(rdg_build_partitions): Do not call
	fuse_partitions_with_similar_memory_accesses here...
	(ldist_gen): ... but here after classifying all partitions.
	Remove failure path of generate_code_for_partition.
	(generate_code_for_partition): Generate code according
	to partition classification.
