It -- is used when a label is created by the expander without bothering -- to insert an N_Implicit_Label_Declaration in the tree. It also takes -- care of setting Reachable, since labels defined by the expander can -- be assumed to be reachable. procedure Check_Possible_Current_Value_Condition (Cnode : Node_Id); -- Cnode is N_If_Statement, N_Elsif_Part, or N_Iteration_Scheme -- (the latter when a WHILE condition is present). This call checks -- if Condition (Cnode) is of the form ([NOT] var op val), where var -- is a simple object, val is known at compile time, and op is one -- of the six relational operators. If this is the case, and the -- Current_Value field of "var" is not set, then it is set to Cnode. -- See Exp_Util.Set_Current_Value_Condition for further details. procedure Check_Unreachable_Code (N : Node_Id); -- This procedure is called with N being the node for a statement that -- is an unconditional transfer of control. It checks to see if the -- statement is followed by some other statement, and if so generates -- an appropriate warning for unreachable code. end Sem_Ch5;
