<pre>There are TWO sets of MOVQ instructions. This I did not know.
There's "MOVD/MOVQ—Move Doubleword/Move Quadword"
NP REX.W + 0F 6E /r MOVQ mm, r/m64
NP REX.W + 0F 7E /r MOVQ r/m64, mm
66 REX.W 0F 6E /r MOVQ xmm, r/m64
66 REX.W 0F 7E /r MOVQ r/m64, xmm
NP 0F 6E /r MOVD mm, r/m32
NP 0F 7E /r MOVD r/m32, mm
66 0F 6E /r MOVD xmm, r/m32
66 0F 7E /r MOVD r/m32, xmm
and there is also "MOVQ—Move Quadword"
NP 0F 6F /r MOVQ mm, mm/m64
NP 0F 7F /r MOVQ mm/m64, mm
F3 0F 7E /r MOVQ xmm1, xmm2/m64
The first does NOT support MOVD mm0, mm1. The second supports MOVQ mm0, mm1.
No bug.</pre>
