	gcc            : ChangeLog Makefile.in tree-cfg.c tree-flow.h 
	                 tree-outof-ssa.c tree-phinodes.c tree-ssa-dom.c

Added files:
	gcc            : tree-ssa-threadupdate.c 

Log message:
	* Makefile.in (OBJC-common): Add tree-ssa-threadupdate.c
	(tree-ssa-threadupdate.o): Add dependencies.
	* tree-ssa-threadupdate.c: New file.
	* tree-flow.h (incoming_edge_threaded): New flag in block annotation.
	(rewrite_vars_out_of_ssa): Remove prototype.
	(cleanup_tree_cfg): Returns a bool.
	* tree.h (thread_through_all_blocks): Prototype.
	* tree-outof-ssa.c  (SSANORM_*): Move into here.
	(remove_ssa_form): Now static.
	(rewrite_vars_out_of_ssa): Kill.
	* tree-ssa-live.c (register_ssa_partitions_for_vars): Kill.
	* tree-ssa-live.h (SSANORM_*): Moved into tree-outof-ssa.c.
	(remove_ssa_form, register_partitions_for_vars): Kill declarations.
	* tree-cfg.c (cleanup_tree_cfg): Return a value indicating if
	anything was changed.
	* tree-phinodes.c (add_phi_arg): Get the block for the PHI
	from the PHI's annotation rather than the edge associated with
	the new argument.
	* tree-ssa-dom.c (redirection_edges): Kill.
	(redirect_edges_and_update_ssa_graph): Kill.
	(tree_ssa_dominator_optimize): Do not reset forwardable flag
	for blocks anymore.  Do not initialize redirection_edges.
	Call thread_through_all_blocks.  Simplify code for cleanup
	of the CFG and iterating.  No longer call cleanup_tree_cfg
	outside the iteration loop.
	(thread_across_edge): No longer mess with forwardable blocks.
