   procedure Initialize;
   --  Initialize internal tables for a new compilation
 
   procedure SCO_Record (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_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_Output;
   --  Outputs SCO lines for all units, with appropriate section headers, for
   --  unit U in the ALI file, as recorded by previous calls to SCO_Record,
   --  possibly modified by calls to Set_SCO_Condition.
 
   procedure dsco;
   --  Debug routine to dump internal SCO table. This is a raw format dump
   --  showing exactly what the table contains.
 
   procedure pscos;
   --  Debugging procedure to output contents of SCO binary tables in the
   --  format in which they appear in an ALI file.
