 @defmac LIBCALL_VALUE (@var{mode})
 A C expression to create an RTX representing the place where a library
-function returns a value of mode @var{mode}.  If the precise function
-being called is known, @var{func} is a tree node
-(@code{FUNCTION_DECL}) for it; otherwise, @var{func} is a null
-pointer.  This makes it possible to use a different value-returning
-convention for specific functions when all their calls are
-known.
+function returns a value of mode @var{mode}.
 
 Note that ``library function'' in this context means a compiler
 support routine, used to perform arithmetic, whose name is known
 specially by the compiler and was not mentioned in the C code being
 compiled.
-
-The definition of @code{LIBRARY_VALUE} need not be concerned aggregate
-data types, because none of the library functions returns such types.
