Hmm, it wasn't clear to me fromt he error report exactly which
instructions it was complaining about, so I guessed this was one of
them:

https://gmplib.org/repo/gmp/file/tip/mpn/x86_64/core2/hamdist.asm#l194

  movq	%xmm0, %rax

For the memory accesses, e.g., 

  movq	(up), %xmm1

I agree changing those to movd sounds scary.
