-	* bb-reorder.c (make_reorder_chain_1): Modified.
+	* bb-reorder.c (make_reorder_chain_1): Use prev_bb/next_bb to get to
+	neighbouring basic blocks.  Use ENTRY_BLOCK_PTR->next_bb instead of
+	BASIC_BLOCK (0).  Use EXIT_BLOCK_PTR->prev_bb instead of
+	BASIC_BLOCK (n_basic_blocks - 1).

-	flow_preorder_transversal_compute): Modified.
+	flow_preorder_transversal_compute): Too.
 	* cfgbuild.c (make_edges, find_basic_blocks, find_many_sub_basic_blocks,
-	find_sub_basic_blocks): Modified.
-	* cfgcleanup.c (try_simplify_condjump, try_optimize_cfg): Modified.
+	find_sub_basic_blocks): Too.
