	gcc            : ChangeLog.tree-ssa Makefile.in domwalk.c 
	                 domwalk.h tree-ssa-dom.c tree-ssa.c 

Log message:
	* Makefile.in (domwalk.o): Depend on $(GGC_H).
	* domwalk.c: Include ggc.h.
	(walk_dominator_tree): Manage allocation/deallocation and
	pushing/popping of the toplevel block data pointer here.
	Use callback to initialize the block local data.
	(init_walk_dominator_tree): New function.
	(fini_walk_dominator_tree): Likewise.
	* domwalk.h (struct dom_walk_data): Add callback to initialize
	block local data.  Add field for sizeof block local data.
	Add "private" field free_block_data.
	(init_dominator_tree, fini_dominator_tree): Prototype.
	* tree-ssa-dom.c (dom_opt_initialize_local_data): New function.
	(tree_ssa_dominator_optimize_1): Initialize new fields in the
	dominator walker structure.  Initialize and finalize the dominator
	walker.  Slightly reorder code to make it more readable..
	(dom_opt_initialize_block): No longer deal with allocation and
	initialization of block local data.
	(dom_opt_finalize_block): Similarly for deallocation of block
	local data.
	* tree-ssa.c (rewrite_block_data): New structure.
	(rewrite_initialize_block_local_data): New function.
	(rewrite_initialize_block): No longer deal with allocation and
	initialization of block local data.
	(rewrite_into_ssa): Initialize new fields in the dominator walker
	structure.  Initialize and finalize the dominator walker.
	(rewrite_initialize_block): No longer deal with allocation and
	initialization of block local data.
	(rewrite_optimize_stmts): Deal with changes in the dominator
	walker structure.
	(rewrite_finalize_block): No longer with deallocation of block
	local data.
