2019-12-13modulo-sched: speed up DDG analysis (PR90001)Roman Zhuykov1-6/+6
PR rtl-optimization/90001 * ddg.c (create_ddg): Init max_dist array for each node. (free_ddg): Free max_dist array. (create_ddg_edge): Use bool field instead of aux union. (set_recurrence_length): Use prepared max_dist information instead of calling longest_simple_path. (create_scc): Remove graph argument, fill node's aux.count with SCC id, and move set_recurrence_length call to... (create_ddg_all_sccs): ...here, after filling all max_dist arrays using Floyd–Warshall-like algorithm. (update_dist_to_successors): Remove the whole function. (longest_simple_path): Likewise. * ddg.h (struct ddg_node): Add max_dist pointer. (struct ddg_edge): Use bool field instead of unused aux union. From-SVN: r279375
