So, what is the problem with this? Either the compiler knows that unaligned accesses are no problem and optimizes them away anyway, or it is kept because it would crash otherwise. I can confirm that no sparc version >= 3.5 (have not tried older) survives the test suite on Gentoo Sparc (64 bit kernel, 32 bit userspace) without memcpy().
