| 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_Node_Briefly (N : Node_Id); |
| -- Terse version of Print_Tree_Node |
| |
| 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. |

| -- Union_Id. |

| procedure ppp (N : Node_Id); |

| -- Same as Print_Node_Subtree |
| |
| -- The following are no longer needed; you can use pp or ppp instead |
| |
| procedure pe (E : Elist_Id); |
| pragma Export (Ada, pe); |
| -- Same as Print_Tree_Elist |
| |
| procedure pl (L : Int); |
| pragma Export (Ada, pl); |
| -- 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. |
