@ -733,14 +733,13 @@ Currently, only the following parameter attributes are defined:
attribute for return values and can only be applied to one parameter.
``returned``
This indicates that the value of the function always returns the value
of the parameter as its return value. This is an optimization hint to
the code generator when generating the caller, allowing tail call
optimization and omission of register saves and restores in some cases;
it is not checked or enforced when generating the callee. The parameter
and the function return type must be valid operands for the
:ref:`bitcast instruction <i_bitcast>`. This is not a valid attribute for
return values and can only be applied to one parameter.
