<pre>In <emmintrin.h>, _mm_loadu_si128 is declared as:
static __inline__ __m128i __attribute__((__always_inline__, __nodebug__))
_mm_loadu_si128(__m128i const *__p)
i.e., taking a (__m128i const *) parameter. This is a bug, since __m128i is
16-byte aligned, and the whole point of the _mm_loadu_si128 is that it performs
*unaligned* loads -- so you're forcing people to write code which produces
"cast increases required alignment" warnings.
I realize that this was Intel's bug originally, but I don't see any reason why
you can't fix it.</pre>
