[LLVMdev] [clang] SSE2 intrinsics (emmintrin.h): _mm_movpi64_pi64 should be _mm_movpi64_epi64?
...ut without the `e', _mm_movpi64_pi64():
static __inline__ __m128i __attribute__((__always_inline__, __nodebug__))
_mm_movpi64_pi64(__m64 __a)
{
return (__m128i){ (long long)__a, 0 };
}
Microsoft (http://msdn.microsoft.com/en-us/library/has3d153(v=vs.90).aspx)
defines these two:
_mm_movepi64_pi64 MOVDQ2Q Move
_mm_movpi64_epi64 MOVQ2DQ Move
That is:
__m64 _mm_movepi64_pi64 (__m128i a);
MOVDQ2Q
r0 := a0 ;
__m128i _mm_movpi64_epi64 (__m64 a);
MOVDQ2Q
r0 := a0 ; r1 := 0X0 ;
Cf. Intel's manual [1]:
_mm_movepi64_pi64 Move MOVDQ2Q
_mm_movpi64_epi64 Move MOVDQ...
