Many thanks to huchangqi. Now we have loongarch64 support for both old
world ABI and new world ABI on the buildfarm!

are kind of nice in this environment, but honestly I have no idea how
much this architecture is used. Perhaps that's only something in
China? I am not seeing much activity around that
Thanks for the comment. I have updated the patch to v3. Please have a look.

I think so.

Okay, so it's not "necessary" in the sense that it's illegal,

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.
