Since Nkind functions logically in a manner similar to a variant -- record discriminant part, such alterations cannot be permitted in a -- general manner, but in some specific cases, the fields of related nodes -- have been deliberately laid out in a manner that permits such alteration. package Sinfo.CN is procedure Change_Identifier_To_Defining_Identifier (N : in out Node_Id); -- N must refer to a node of type N_Identifier. This node is modified to -- be of type N_Defining_Identifier. The scanner always returns identifiers -- as N_Identifier. The parser then uses this routine to change the node -- to be a defining identifier where the context demands it. This routine -- also allocates the necessary extension node. Note that this procedure -- may (but is not required to) change the Id of the node in question. procedure Change_Character_Literal_To_Defining_Character_Literal (N : in out Node_Id); -- Similar processing for a character literal procedure Change_Operator_Symbol_To_Defining_Operator_Symbol (N : in out Node_Id); -- Similar processing for an operator symbol procedure Change_Conversion_To_Unchecked (N : Node_Id); -- Change checked conversion node to unchecked conversion node, clearing -- irrelevant check flags (other fields in the two nodes are identical) procedure Change_Operator_Symbol_To_String_Literal (N : Node_Id); -- The scanner returns any string that looks like an operator symbol as -- a N_Operator_Symbol node. The parser then uses this procedure to change -- the node to a normal N_String_Literal node if the context is not one -- in which an operator symbol is required. There are some cases where the -- parser cannot tell, in which case this transformation happens later on. procedure Change_Selected_Component_To_Expanded_Name (N : Node_Id); -- The parser always generates Selected_Component nodes. The semantics -- modifies these to Expanded_Name nodes where appropriate. Note that -- on return the Chars field is set to a copy of the contents of the -- Chars field of the Selector_Name field. end Sinfo.CN;
