package Treepr is
-- This package provides printing routines for the abstract syntax tree
-- These routines are intended only for debugging use.
procedure Tree_Dump;
-- This routine is called from the GNAT main program to dump trees as
-- requested by debug options (including tree of Standard if requested).
procedure Print_Tree_Node (N : Node_Id; Label : String := "");
-- Prints a single tree node, without printing descendants. The Label
-- string is used to preface each line of the printed output.
procedure Print_Tree_List (L : List_Id);
-- Prints a single node list, without printing the descendants of any
-- of the nodes in the list
procedure Print_Tree_Elist (E : Elist_Id);
-- Prints a single node list, without printing the descendants of any
-- of the nodes in the list
procedure Print_Node_Subtree (N : Node_Id);
-- Prints the subtree routed at a specified tree node, including all
-- referenced descendants.
procedure Print_List_Subtree (L : List_Id);
-- Prints the subtree consisting of the given node list and all its
-- referenced descendants.
procedure Print_Elist_Subtree (E : Elist_Id);
-- Prints the subtree consisting of the given element list and all its
-- referenced descendants.
procedure pe (E : Elist_Id);
pragma Export (Ada, pe);
-- Debugging procedure (to be called within gdb), same as Print_Tree_Elist
procedure pl (L : Int);
pragma Export (Ada, pl);
-- Debugging procedure (to be called within gdb), same as Print_Tree_List,
-- except that you can use e.g. 66 instead of -99999966. In other words
-- for the positive case we fill out to 8 digits on the left and add a
-- minus sign. This just saves some typing in the debugger.

procedure pt (N : Node_Id);
