	gcc            : ChangeLog.tcb domwalk.c domwalk.h tree-flow.h 
	                 tree-into-ssa.c tree-ssa-dom.c tree-ssa-dse.c 
	                 tree-vrp.c 

Log message:
	* domwalk.c (walk_dominator_tree): If block BB is not in the
	set of interesting blocks, do not traverse its statements.
	* domwalk.h (struct dom_walk_data): Add field INTERESTING_BLOCKS.
	* tree-flow.h (update_ssa): Add new bool argument.
	* tree-into-ssa.c (struct mark_def_sites_global_data): Fix comment.
	Add field interesting_blocks.
	(compute_global_livein): Use last_basic_block to initialize
	work lists.
	(find_idf): Likewise.
	(mark_def_sites): If the statement is going to be rewritten,
	add the block to GD->INTERESTING_BLOCKS.
	(rewrite_blocks): Add argument BLOCKS.  Initialize
	WALK_DATA.INTERESTING_BLOCKS with it.
	Update all callers.
	Move debug dumping code from rewrite_into_ssa.
	Only delete DEF_BLOCKS if it had been allocated.
	(mark_def_site_blocks): Add argument INTERESTING_BLOCKS.
	Initialize MARK_DEF_SITES_GLOBAL_DATA.INTERESTING_BLOCKS with
	it.
	Update all callers.
	(prepare_block_for_update): Add arguments INSERT_PHI_P and
	INTERESTING_BLOCKS.
	Only call set_def_block/set_livein_block if INSERT_PHI_P is true.
	Update all callers.
	If the block contains at least one interesting statement, add
	the block to INTERESTING_BLOCKS.
	(update_ssa): Add argument INSERT_PHI_P.  Only add new PHI
	nodes if INSERT_PHI_P is true.
	Update all callers.
	Initialize INTERESTING_BLOCKS.
	* tree-ssa-dom.c (tree_ssa_dominator_optimize): Initialize
	WALK_DATA.INTERESTING_BLOCKS to NULL.
	* tree-ssa-dse.c (tree_ssa_dse): Likewise.
