Thanks for the information.
I checked the assembly code of __sync_lock_test_and_set generated by GCC
for loongarch64. It is exactly the same as this patch.
I guess this patch is not necessary any more.

This came up before, and our response was

In principle, at least, there is no longer any need for
machine-specific s_lock.h
Hi,
This patch set tries to add loongarch64 native spin lock to postgresql.
- [PATCH 1/2] implements a loongarch64 native spin lock.
- [PATCH 2/2] fixes s_lock_test to make it runnable via `make check'.
The patch set is tested on my Loongson 3A5000 machine with Loong Arch
Linux and GCC 13.1.0
