-- Operator Precedence Table --
-------------------------------
-- This table is used to decide whether a subexpression needs to be

-- with a lower precedence than the operator (or equal precedence if
-- appearing as the right operand), then parentheses are required.

-- Local Subprograms --
-----------------------
procedure Col_Check (N : Nat);
-- Check that at least N characters remain on current line, and if not,
-- then start an extra line with two characters extra indentation for
-- continuing text on the next line.
procedure Extra_Blank_Line;
-- In some situations we write extra blank lines to separate the generated
-- code to make it more readable. However, these extra blank lines are not
-- generated in Dump_Source_Text mode, since there the source text lines
-- output with preceding blank lines are quite sufficient as separators.
-- 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
-- new line, when it would otherwise be inclined to do so (e.g. the case
-- of an accept statement called from an accept alternative with a guard)
procedure Indent_Begin;
-- Increase indentation level
procedure Indent_End;
-- Decrease indentation level
procedure Note_Implicit_Run_Time_Call (N : Node_Id);
-- N is the Name field of a function call or procedure statement call.
-- 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 @).
procedure Set_Debug_Sloc;
-- If Dump_Node is non-empty, this routine sets the appropriate value
-- in its Sloc field, from the current location in the debug source file
-- that is currently being written.
procedure Sprint_And_List (List : List_Id);
-- Print the given list with items separated by vertical "and"
procedure Sprint_Bar_List (List : List_Id);
-- Print the given list with items separated by vertical bars
procedure Sprint_End_Label
(Node : Node_Id;
Default : Node_Id);
-- Print the end label for a Handled_Sequence_Of_Statements in a body.
-- If there is not end label, use the defining identifier of the enclosing
-- construct. If the end label is present, treat it as a reference to the
-- defining entity of the construct: this guarantees that it carries the
-- 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
-- of the sprinted node Node. Note that this is done after printing
-- Node, so that the Sloc is the proper updated value for the debug file.
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
-- type can be an Itype, such as defining_identifiers that may be of
-- an anonymous access type, or ranges in slices.
procedure Write_Char_Sloc (C : Character);
-- Like Write_Char, except that if C is non-blank, Set_Debug_Sloc is
-- called to ensure that the current node has a proper Sloc set.
procedure Write_Condition_And_Reason (Node : Node_Id);
-- Write Condition and Reason codes of Raise_xxx_Error node
procedure Write_Corresponding_Source (S : String);
-- If S is a string with a single keyword (possibly followed by a space),
-- and if the next non-comment non-blank source line matches this keyword,
-- then output all source lines up to this matching line.
procedure Write_Discr_Specs (N : Node_Id);
-- Output discriminant specification for node, which is any of the type
-- declarations that can have discriminants.
procedure Write_Ekind (E : Entity_Id);
-- Write the String corresponding to the Ekind without "E_"
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);
pragma Warnings (Off, Write_Implicit_Def);
-- Write the definition of the implicit type E according to its Ekind
-- For now a debugging procedure, but might be used in the future.
procedure Write_Indent;
-- Start a new line and write indentation spacing
function Write_Indent_Identifiers (Node : Node_Id) return Boolean;
-- Like Write_Identifiers except that each new printed declaration
-- is at the start of a new line.
function Write_Indent_Identifiers_Sloc (Node : Node_Id) return Boolean;
-- Like Write_Indent_Identifiers except that in Debug_Generated_Code
-- mode, the Sloc of the current debug node is set to point to the
-- 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,
-- then "--" and the line number followed by period followed by text of the
-- 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
-- lines Last_Line_Printed + 1 .. L, and updates Last_Line_Printed. If
-- interspersed source line output not enabled, then call has no effect.
procedure Write_Str_Sloc (S : String);
