This patch removes the stmt_vec_info wrapper class added near the beginning of the series and turns stmt_vec_info back into a typedef.
2018-07-24 Richard Sandiford <richard.sandif...@arm.com> gcc/ * tree-vectorizer.h (stmt_vec_info): Turn back into a typedef. (NULL_STMT_VEC_INFO): Delete. (stmt_vec_info::operator*): Likewise. (stmt_vec_info::operator gimple *): Likewise. * tree-vect-loop.c (vectorizable_reduction): Use NULL instead of NULL_STMT_VEC_INFO. * tree-vect-patterns.c (vect_init_pattern_stmt): Likewise. (vect_reassociating_reduction_p): Likewise. * tree-vect-stmts.c (vect_build_gather_load_calls): Likewise. (vectorizable_store): Likewise. * tree-vectorizer.c (vec_info::set_vinfo_for_stmt): Likewise. (vec_info::free_stmt_vec_infos): Likewise.
