remove STMT_VINFO_NUM_SLP_USES
This removes STMT_VINFO_NUM_SLP_USES by pushing the setting of the shared stmt_vec_info vector type to where we actually need it which is alignment analysis and vectorizable_* analysis (where we could eventually elide it for non-load/store operations). In particular "uses" in the cache and in disqualified SLP subgraphs should no longer provide conflicting vector types this way. 2020-09-16 Richard Biener <rguenther@suse.de> * tree-vectorizer.h (_stmt_vec_info::num_slp_uses): Remove. (STMT_VINFO_NUM_SLP_USES): Likewise. (vect_free_slp_instance): Adjust. (vect_update_shared_vectype): Declare. * tree-vectorizer.c (vec_info::~vec_info): Adjust. * tree-vect-loop.c (vect_analyze_loop_2): Likewise. (vectorizable_live_operation): Use vector type from SLP_TREE_REPRESENTATIVE. (vect_transform_loop): Adjust. * tree-vect-data-refs.c (vect_slp_analyze_node_alignment): Set the shared vector type. * tree-vect-slp.c (vect_free_slp_tree): Remove final_p parameter, remove STMT_VINFO_NUM_SLP_USES updating. (vect_free_slp_instance): Adjust. (vect_create_new_slp_node): Remove STMT_VINFO_NUM_SLP_USES updating. (vect_update_shared_vectype): Always compare with the present vector type, update if NULL. (vect_build_slp_tree_1): Do not update the shared vector type here. (vect_build_slp_tree_2): Adjust. (slp_copy_subtree): Likewise. (vect_attempt_slp_rearrange_stmts): Likewise. (vect_analyze_slp_instance): Likewise. (vect_analyze_slp): Likewise. (vect_slp_analyze_node_operations_1): Update the shared vector type. (vect_slp_analyze_operations): Adjust. (vect_slp_analyze_bb_1): Likewise.
