PR tree-optimization/56118 * tree-vectorizer.h (vect_find_last_scalar_stmt_in_slp): Declare. * tree-vect-slp.c (vect_find_last_scalar_stmt_in_slp): Export. * tree-vect-data-refs.c (vect_slp_analyze_node_dependences): New function. (vect_slp_analyze_data_ref_dependences): Instead of computing all dependences of the region DRs just analyze the code motions SLP vectorization will perform. Remove SLP instances that cannot have their store/load motions applied. (vect_analyze_data_refs): Allow DRs without a vectype in BB vectorization. * gcc.dg/vect/no-tree-sra-bb-slp-pr50730.c: Adjust. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@230020 138bc75d-0d04-0410-961f-82ee72b054a4
