A.5.180 MOVSS: Move Scalar Single-Precision FP Value
MOVSS xmm1,xmm2/m32 ; F3 0F 10 /r [KATMAI,SSE]
MOVSS xmm1/m32,xmm2 ; F3 0F 11 /r [KATMAI,SSE]
MOVSS moves a single-precision FP value from the source operand to the
destination operand. When the source or destination is a register, the
low-order FP value is read or written.
