	gcc            : ChangeLog.tree-ssa tree-ssa-dom.c 

Log message:
	* tree-ssa-dom.c (thread_across_edge): Renamed from
	thread_through_successor.  Revamp to thread the destination of an edge
	rather than the successors of a block.
	(dom_opt_finalize_block): Corresponding changes.  Do not bother calling
	thread_across_edge unless we are at a leaf in the dominator tree.
