-----------------
-- 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.
