(flow_loop_tree_node_add): Handle subloops of added loop correctly. (get_loop_exit_edges): New. (verify_loop_structure): Verify EDGE_IRREDUCIBLE_LOOP flags. * cfgloop.h (flow_loop_free, get_loop_exit_edges, unloop): Declare. * cfgloopanal.c (mark_irreducible_loops): Mark edges in irreducible loops. * cfgloopmanip.c (loop_delete_branch_edge): Allow to test for removability of an edge. (fix_irreducible_loops): New static function. (find_path, remove_path): Add ability to remove enclosing loops. (unloop): New. (copy_bbs, duplicate_loop_to_header_edge): Use EDGE_IRREDUCIBLE_LOOP flags. * cfgrtl.c (verify_flow_info): Handle EDGE_IRREDUCIBLE_LOOP flag. * loop-unroll.c (peel_loops_completely): Do not duplicate loop if not neccessary.
