with Namet; use Namet;
package Butil is
-- This package contains utility routines for the binder
function Is_Predefined_Unit return Boolean;
-- Given a unit name stored in Name_Buffer with length in Name_Len,
-- returns True if this is the name of a predefined unit or a child of
-- a predefined unit (including the obsolescent renamings). This is used
-- in the preference selection (see Better_Choice in body of Binde).
function Is_Internal_Unit return Boolean;
-- Given a unit name stored in Name_Buffer with length in Name_Len,
-- returns True if this is the name of an internal unit or a child of
-- an internal unit. Similar in usage to Is_Predefined_Unit.
-- Note: the following functions duplicate functionality in Uname, but
-- we want to avoid bringing Uname into the binder since it generates
-- to many unnecessary dependencies, and makes the binder too large.
function Uname_Less (U1, U2 : Unit_Name_Type) return Boolean;
-- Determines if the unit name U1 is alphabetically before U2
procedure Write_Unit_Name (U : Unit_Name_Type);
-- Output unit name with (body) or (spec) after as required. On return
-- Name_Len is set to the number of characters which were output.
