The C11 support for atomic primitive since 2011. Whether the compiler like gcc has support all the atomic primitives and for all architectures? And Rtems does not use standard library provided by compiler, so we still support all the atomic primitives on the newlib. There are also lots of work to do if we support all the atomic primitives defined by C11 standard
