Hi,

I just pushed changes to the ci script to enable sparc64 tests. It turned out to be rather easy with current debian-based tools, despite sparc64 no longer being a release architecture. (Install gcc-sparc64-linux-gnu cross compiler, use qemu-sparc64, only workaround (similar to some other archs) was that QEMU_LD_PREFIX had to be set explicitly).

I don't now if anyone is interested in sparc performance, or contributing more sparc64 code (I'd consider this architecture rather obscure by now). But these tests should at least make it rather easy to maintain the code for the time being. Even as I consider some changes to the handling aes decryption subkeys that will require updates to this code.

On the other hand, I'm considering deleting the sparc32 assembly code. Related machines like the sparc stations (I don't remember if I had a SS-5, SS-10 or SS-20 at the time I wrote this code, but I remember I had redhat linux installed on it rather than solaris) are out of support since the late 1990s. 64-bit sparcs, aka sparc v9, were introduced with the ultrasparc machines from 1995.
