This case, we call vect_create_addr_base_for_vector_ref and then expect the new_stmt_list not be to empty. I am starting to think we should have bsi_insert_on_edge_immediate just return NULL when it is past NULL now. -- pinskia at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |pinskia at gcc dot gnu dot | |org Component|c |tree-optimization http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32477 ^ permalink raw reply [flat|nested] 6+ messages in thread
