``nocapture``
This indicates that the callee does not make any copies of the
- pointer that outlive the callee itself. This is not a valid
+ pointer that outlive the callee itself in any form such as a pointer stored
+ in the memory or as a return value. This is not a valid
attribute for return values. Addresses used in volatile operations
are considered to be captured.
