IIRC, PostgreSQL do not support loongarch platform, so if you want to
use PostgreSQL on loongarch, you can a) disable spinlock when executing
configure (not recommended for production) or b) implement a spinlock
for PostgreSQL on loongarch64 platform.

Maybe you could encounter other questions on loongarch, I'm not sure.

Wikipedia suggests that loongarch is more or less a MIPS clone,
so maybe you could adapt the MIPS stanza in s_lock.h to work.

Do "make check" in src/backend/storage/lmgr for a basic smoke-test
of new spinlock code.
