| -- Subprograms -- |
| ----------------- |
| |
| procedure Initialize; |
| -- Initialize internal tables for a new compilation |
| |
| procedure SCO_Record_Raw (U : Unit_Number_Type); |
| -- This procedure scans the tree for the unit identified by U, populating |
| -- internal tables recording the SCO information. 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. |
