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 with default ./configure with no options.
Output of `make check' in src/backend/storage/lmgr is attached.
