tree-vect-data-refs.c (vect_analyze_data_ref_dependences): Allocate the data dependence vector.

2015-10-13  Richard Biener  <rguenther@suse.de>

	* tree-vect-data-refs.c (vect_analyze_data_ref_dependences): Allocate
	the data dependence vector.
	(vect_peeling_hash_insert): Get the peeling hash table as argument.
	(vect_peeling_hash_get_lowest_cost): Likewise.
	(vect_enhance_data_refs_alignment): Adjust.
	(struct _vect_peel_info, struct _vect_peel_extended_info,
	struct peel_info_hasher): Move from ...
	* tree-vectorizer.h: ... here.
	(LOOP_VINFO_COST_MODEL_MIN_ITERS): Remove.
	(LOOP_VINFO_PEELING_HTAB): Likewise.
	(struct _loop_vec_info): Remove min_profitable_iters and
	peeling_htab members.
	* tree-vect-loop.c (new_loop_vec_info): Do not allocate vectors
	here.
	(destroy_loop_vec_info): Adjust.
	(vect_analyze_loop_2): Do not set LOOP_VINFO_COST_MODEL_MIN_ITERS.
	(vect_estimate_min_profitable_iters): Use LOOP_VINFO_COMP_ALIAS_DDRS
	to estimate alias versioning cost.
	* tree-vect-slp.c (vect_analyze_slp_cost): Dump header.
