Okay, I think I know what is going on then. I've been working with the optimized poly1305 MAC code from floodyberry (github.com/floodyberry/poly1305-opt) and the problem seems to be that it just is too old to properly support armv8. Specifically in that the assembly was only written for 32bit processors. I was getting turned around buy an error message that, for some reason, made me think that it was a problem with the neon code and not the armv6 assembly. 

Thanks!
