I'm not convinced that implementing the movmisalign optab would fix the problem without a major degradation in performance. Sparc and mips also don't implement movmisalign. Structs are passed by reference on this target if they are larger than 64 bits and the reference is misaligned in this testcase. So, I agree the test should be xfailed.
