	gcc            : ChangeLog.tree-ssa tree-flow.h tree-ssa-dom.c 
	                 tree-ssa.c gimplify.c tree-cfg.c tree.h 

Log message:
	* tree-flow.h: Update copyright dates.
	(register_new_def): Declare.
	* tree-ssa-dom.c: Update copyright dates.
	Add tracking of current definition of each program variable just
	like we do when rewriting into SSA form.
	(get_value_for, set_value_for): Handle either an SSA_NAME or
	regular variable.
	(tree_ssa_dominator_optimize): Initialize and update CURRDEFS.
	If we thread through a block with real statements, the destination
	of those statements must be rewritten too.
	(thread_across_edge): Skip nop statements at the start of a
	block.
	(dom_opt_initialize_block_local_data): Clear block_defs
	appropriately.
	(record_equivalences_from_phis): Accept walk_data structure.
	Call register_new_def appropriately.
	(optimize_stmt): Call register_new_defs_for_stmt.
	(dom_opt_finalize_block): Restore CURRDEFS appropriately.
	(register_new_definitions_for_stmt): New.
	* tree-ssa.c: Update copyright dates.
	(register_new_def): No longer static.  Accept additional argument
	for the table to hold the new definition.  Callers updated.
	
	* gimplify.c: Update copyright dates.
	* tree-cfg.c: Likewise.
	* tree.h: Likewise.
