Reaching definitions in (RD_in) is initially empty for all nodes. Gen and kill sets are computed. AST node numbers are used for nodes to refer to their definition number. Also: two small changes to flow graph printing. Children of branch nodes are visited in right-to-left order when performing depth first search. Instructions are numbered locally within blocks so as to not destroy AST node number before printing (it's useful to print the definition).
