| procedure Analyze_Label_Entity (E : Entity_Id); |
| -- This procedure performs direct analysis of the label entity E. 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. |
