re PR tree-optimization/18437 (vectorizer failed for matrix multiplication)
PR tree-optimization/18437
* tree-vectorizer.h (_stmt_vec_info.stride_load_p): New member.
(STMT_VINFO_STRIDE_LOAD_P): New accessor.
(vect_check_strided_load): Declare.
* tree-vect-data-refs.c (vect_check_strided_load): New function.
(vect_analyze_data_refs): Use it to accept strided loads.
* tree-vect-stmts.c (vectorizable_load): Ditto and handle them.
