No _mm_stream_si64() function in emmintrin.h.

emmintrin.h of Intel C contains:

#if defined(__x86_64) || defined(_M_X64)
extern __int64 __ICL_INTRINCC _mm_cvtsd_si64(__m128d);
extern __int64 __ICL_INTRINCC _mm_cvttsd_si64(__m128d);
extern __m128d __ICL_INTRINCC _mm_cvtsi64_sd(__m128d, __int64);
extern    void __ICL_INTRINCC _mm_stream_si64(__int64 *, __int64);

emmintrin.h of GNU C contains:

#ifdef __x86_64__
extern __inline void __attribute__((__gnu_inline__, __always_inline__,
_mm_stream_si64 (long long int *__A, long long int __B)
  __builtin_ia32_movnti64 (__A, __B);
