grep shows:
sysdeps/x86_64/multiarch/strcspn-c.c: mask = _mm_loadu_si128 ((__m128i
*) a);
sysdeps/x86_64/multiarch/varshift.h: _mm_loadu_si128 ((__m128i *)
(___m128i_shift_right
sysdeps/x86_64/multiarch/strspn-c.c: mask = _mm_loadu_si128 ((__m128i
*) a);
sysdeps/x86_64/multiarch/strstr.c: return _mm_loadu_si128 ((__m128i *) p);
And looking at the files, it's (except varshift.h) the input parameter that is
returned. In these cases the loadu is always needed.
