Usage: MOVHLPS  dest,src                             Modifies flags: None

Moves two packed single-precision floating-point values from the low quadword of the 'src' to the high quadword of the 'dest'. The low quadword of the 'dest'  operand is left unchanged.

Move Packed Single-Precision FP High to Low

MOVHLPS xmm1,xmm2             ; OF 12 /r        [KATMAI,SSE]

MOVHLPS moves the two packed single-precision FP values from the high quadword of the source register xmm2 to the low quadword of the destination register, xmm2. The upper quadword of xmm1 is left unchanged.

The operation of this instruction is:

   dst[0-63]   := src[64-127],

   dst[64-127] remains unchanged.
