use of compare_exchange_weak
Both for enqueing and dequeing, why not using compare_exchange_weak / std::memory_order_relaxed (instead of compare_exchange_strong / memory_order_seq_cst) like in Dmitry Vyukov latest implementation (2021)?
This seems to make sense, as we are in a loop.

yes I haven't optimized for ARM. Ideally there should only be single dmb barrier.
