<pre class="content">Stephen,
Thanks for your comments! I'm evaluating the generic code of spinlock
on std atomics of LoongArch toolchain. An updated patch will come later.

<pre class="moz-quote-pre" wrap="">This patch adds spinlock operations for LoongArch architecture.
These implementations refer to GLIBC pthread_spin_xxlock(). The
underlying implementation is based on LoongArch atomic
instructions (ie, AMSWAP_DB.W).

If you supported std atomics, then the g eneric code
could work here.
