Note that this is done -- before any semantic analysis/expansion happens. procedure Set_SCO_Condition (Cond : Node_Id; Val : Boolean); -- This procedure is called during semantic analysis to record a condition -- which has been identified as always True or always False, as indicated -- by Val. The condition is identified by the First_Sloc value in the -- original tree associated with Cond. procedure Set_SCO_Logical_Operator (Op : Node_Id); -- Mark some putative logical operator as a short circuit one procedure Set_SCO_Pragma_Enabled (Loc : Source_Ptr); -- This procedure is called from Sem_Prag when a pragma is enabled (i.e. -- when the Pragma_Enabled flag is set). Loc is the Sloc of the N_Pragma -- node. This is used to enable the corresponding statement SCO entry. Note -- that we use the Sloc as the key here, since in the generic case, the -- analysis is on a copy of the node, which is different from the node -- seen by Par_SCO in the parse tree (but the Sloc values are the same). function SCO_Pragma_Disabled (Loc : Source_Ptr) return Boolean; -- True if Loc is the source location of a disabled pragma procedure SCO_Record_Filtered; -- This procedure filters remaining putative AND/OR short-circuit operators -- from the internal SCO raw table after the semantic analysis and fills -- the filtered SCO table. procedure SCO_Output; -- Outputs SCO lines for all units, with appropriate section headers, as -- recorded by previous calls to SCO_Record, possibly modified by calls to -- Set_SCO_Condition. procedure dsco; -- Debug routine to dump internal SCO tables. This is a raw format dump -- showing exactly what the tables contain. procedure pscos; -- Debugging procedure to output contents of SCO binary tables in the -- format in which they appear in an ALI file. end Par_SCO;
