atomic misses specialization for enums

Reported by: ingo.loehken@… Owned by: timblechmann
Milestone: To Be Determined Component: atomic
Version: Boost 1.56.0 Severity: Optimization
Keywords: enum, atomic Cc: Andrey.Semashev@…

Description

Maybe there is a reason, that boost::atomic does not support a specialization for enums and handles them like user-defined types, but lock-free access to enums would be nice.

I just extended the existing implementation. Ofc, now code is redundant and functions common to integral and enum specializations maybe moved into a base class to avoid that.

The interface for atomic enums is the same as for user-defined structs, and structs up to the supported size are lock-free. What is the purpose of a separate specialization?
