--- Comment #2 from Peter Cordes <peter at cordes dot ca> ---
Can we get this patch applied soon? There aren't any other
strict-aliasing-safe movd load intrinsics, but this one won't be portably
usable while there are buggy GCC versions around.
Until then, code should probably use something like
inline __m128i movd(void *p){
return _mm_castps_si128(_mm_load_ss((const float*)p));
}
(Which believe it or not is strict-aliasing safe even on integer data. At
least it should be; last I tested it was across compilers, except maybe on ICC.
Would have to double-check there.)
