tree-vect-data-refs.c (vect_analyze_data_ref_dependence): Only add RW dependence for dependence distance zero.
2010-04-13 Richard Guenther <rguenther@suse.de>
* tree-vect-data-refs.c (vect_analyze_data_ref_dependence):
Only add RW dependence for dependence distance zero.
Adjust maximal vectorization factor according to dependences.
Move alignment handling ...
(vect_find_same_alignment_drs): ... here. New function.
(vect_analyze_data_ref_dependences): Adjust.
(vect_analyze_data_refs_alignment): Call vect_find_same_alignment_drs.
(vect_analyze_data_refs): Adjust minimal vectorization factor
according to data references.
* tree-vect-loop.c (vect_analyze_loop): Analyze data-ref
dependences before determining the vectorization factor.
Analyze alignment after determining the vectorization factor.
* tree-vect-slp.c ((vect_slp_analyze_bb): Analyze data-ref
dependences before alignment.
* tree-vectorizer.h (vect_analyze_data_ref_dependences):
Adjust prototype.
(vect_analyze_data_refs): Likewise.
(MAX_VECTORIZATION_FACTOR): New define.
* gcc.dg/vect/no-vfa-vect-depend-1.c: Adjust.
