Interestingly, there is no implementation of atomiccopy64 for ARM32. I guess it just relies on the compiler generating LDRD/STRD correctly and doesn't support earlier ARM32 archs. I'll do a bit of investigation.
I am planning to add arch-specific implementations for m68k and sh in the near future. From the current build logs in Debian, it seems that the JVM is actually hanging on these architectures from time to time and I think this could probably be related to atomic_copy64 actually not being 100% atomic. I already added the one for PowerPCSPE.
It's also interesting that there is no implementation for 32-Bit MIPS either.
