[04/11] Add a vect_orig_stmt helper function
This patch just adds a helper function for going from a potential pattern statement to the original scalar statement. 2018-08-01 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vectorizer.h (vect_orig_stmt): New function. * tree-vect-data-refs.c (vect_preserves_scalar_order_p): Use it. * tree-vect-loop.c (vect_model_reduction_cost): Likewise. (vect_create_epilog_for_reduction): Likewise. (vectorizable_live_operation): Likewise. * tree-vect-slp.c (vect_find_last_scalar_stmt_in_slp): Likewise. (vect_detect_hybrid_slp_stmts, vect_schedule_slp): Likewise. * tree-vect-stmts.c (vectorizable_call): Likewise. (vectorizable_simd_clone_call, vect_remove_stores): Likewise. From-SVN: r263217
