Hi Namrata,

Nice to see old hardware still kicking.

I wonder if it would be ok for you to use the stronger std::atomic_thread_fence(std::memory_order_seq_cst) as memory barrier?

We use that for ARM support today, and making that the general fallback implementation of memory barriers would allow Ndb to be built and working on more platforms.

Regards,
Mauritz
