45 -- This procedure performs direct analysis of the label entity E. It
46 -- is used when a label is created by the expander without bothering
47 -- to insert an N_Implicit_Label_Declaration in the tree. It also takes
48 -- care of setting Reachable, since labels defined by the expander can
49 -- be assumed to be reachable.

52 -- This procedure is called with N being the node for a statement that

54 -- statement is followed by some other statement, and if so generates
55 -- an appropriate warning for unreachable code.
