   --  This procedure writes a blank line if Dump_Source_Text is False.

   procedure Indent_Annull;
   --  Causes following call to Write_Indent to be ignored. This is used when
   --  a higher level node wants to stop a lower level node from starting a

   --  The effect of the call is to output a $ if the call is identified as
   --  an implicit call to a run time routine.

   procedure Print_Debug_Line (S : String);
   --  Used to print output lines in Debug_Generated_Code mode (this is used
   --  as the argument for a call to Set_Special_Output in package Output).

   procedure Process_TFAI_RR_Flags (Nod : Node_Id);
   --  Given a divide, multiplication or division node, check the flags
   --  Treat_Fixed_As_Integer and Rounded_Flags, and if set, output the
   --  appropriate special syntax characters (# and @).

   --  that is currently being written.

   --  If there is not end label, use the defining identifier of the enclosing

   --  proper sloc information for debugging purposes.

   procedure Sprint_Node_Actual (Node : Node_Id);
   --  This routine prints its node argument. It is a lower level routine than
   --  Sprint_Node, in that it does not bother about rewritten trees.

   procedure Sprint_Node_Sloc (Node : Node_Id);
   --  Like Sprint_Node, but in addition, in Debug_Generated_Code mode,
   --  sets the Sloc of the current debug node to be a copy of the Sloc

   procedure Update_Itype (Node : Node_Id);
   --  Update the Sloc of an itype that is not attached to the tree, when
   --  debugging expanded code. This routine is called from nodes whose

   --  an anonymous access type, or ranges in slices.

   procedure Write_Char_Sloc (C : Character);

   procedure Write_Ekind (E : Entity_Id);

   procedure Write_Id (N : Node_Id);
   --  N is a node with a Chars field. This procedure writes the name that
   --  will be used in the generated code associated with the name. For a
   --  node with no associated entity, this is simply the Chars field. For
   --  the case where there is an entity associated with the node, we print
   --  the name associated with the entity (since it may have been encoded).
   --  One other special case is that an entity has an active external name
   --  (i.e. an external name present with no address clause), then this
   --  external name is output. This procedure also deals with outputting
   --  declarations of referenced itypes, if not output earlier.

   function Write_Identifiers (Node : Node_Id) return Boolean;
   --  Handle node where the grammar has a list of defining identifiers, but
   --  the tree has a separate declaration for each identifier. Handles the
   --  printing of the defining identifier, and returns True if the type and
   --  initialization information is to be printed, False if it is to be
   --  skipped (the latter case happens when printing defining identifiers
   --  other than the first in the original tree output case).

   procedure Write_Implicit_Def (E : Entity_Id);

   --  first output identifier.

   procedure Write_Indent_Str (S : String);
   --  Start a new line and write indent spacing followed by given string

   procedure Write_Indent_Str_Sloc (S : String);
   --  Like Write_Indent_Str, but in addition, in Debug_Generated_Code mode,
   --  the Sloc of the current node is set to the first non-blank character
   --  in the string S.

   procedure Write_Itype (Typ : Entity_Id);
   --  If Typ is an Itype that has not been written yet, write it. If Typ is
   --  any other kind of entity or tree node, the call is ignored.

   procedure Write_Name_With_Col_Check (N : Name_Id);
   --  Write name (using Write_Name) with initial column check, and possible
   --  initial Write_Indent (to get new line) if current line is too full.

   procedure Write_Name_With_Col_Check_Sloc (N : Name_Id);
   --  Like Write_Name_With_Col_Check but in addition, in Debug_Generated_Code
   --  mode, sets Sloc of current debug node to first character of name.

   procedure Write_Operator (N : Node_Id; S : String);
   --  Like Write_Str_Sloc, used for operators, encloses the string in
   --  characters {} if the Do_Overflow flag is set on the node N.

   procedure Write_Param_Specs (N : Node_Id);
   --  Output parameter specifications for node (which is either a function
   --  or procedure specification with a Parameter_Specifications field)

   procedure Write_Rewrite_Str (S : String);
   --  Writes out a string (typically containing <<< or >>>}) for a node
   --  created by rewriting the tree. Suppressed if we are outputting the
   --  generated code only, since in this case we don't specially mark nodes
   --  created by rewriting).

   procedure Write_Source_Line (L : Physical_Line_Number);
   --  If writing of interspersed source lines is enabled, then write the given
   --  line from the source file, preceded by Eol, then an extra blank line if
   --  the line has at least one blank, is not a comment and is not line one,

   --  source line (without terminating Eol). If interspersed source line
   --  output not enabled, then the call has no effect.

   procedure Write_Source_Lines (L : Physical_Line_Number);
   --  If writing of interspersed source lines is enabled, then writes source

   procedure Write_Str_With_Col_Check (S : String);
   --  Write string (using Write_Str) with initial column check, and possible

   --  Like Write_Str_With_Col_Check, but sets debug Sloc of current debug
   --  node to first non-blank character if a current debug node is active.

   procedure Write_Uint_With_Col_Check (U : Uint; Format : UI_Format);
   --  Write Uint (using UI_Write) with initial column check, and possible
   --  initial Write_Indent (to get new line) if current line is too full.
   --  The format parameter determines the output format (see UI_Write).

   procedure Write_Uint_With_Col_Check_Sloc (U : Uint; Format : UI_Format);
   --  Write Uint (using UI_Write) with initial column check, and possible
   --  initial Write_Indent (to get new line) if current line is too full.
   --  The format parameter determines the output format (see UI_Write).
   --  In addition, in Debug_Generated_Code mode, sets the current node
   --  Sloc to the first character of the output value.

   procedure Write_Ureal_With_Col_Check_Sloc (U : Ureal);
   --  Write Ureal (using same output format as UR_Write) with column checks
   --  and a possible initial Write_Indent (to get new line) if current line
   --  is too full. In addition, in Debug_Generated_Code mode, sets the
