Package: gcc-4.7
Version: 4.7.1-2
Severity: normal
Tags: upstream

Gcc uses unaligned load instruction movdqu even if aligned load movdqa 
was requested and data are aligned.

An example follows

#include <emmintrin.h>
__m128i x(char *s){
  __m128i sz,z,mvec;
  s-=((unsigned long) s)%16;
  sz=_mm_load_si128(s);
  return sz;
}

and output of gcc -O3 -S
