A.5.43 CVTPS2PD: Packed Single-Precision FP to Packed Double-Precision FP
Conversion
CVTPS2PD xmm1,xmm2/mem64 ; 0F 5A /r [WILLAMETTE,SSE2]
CVTPS2PD converts two packed single-precision FP values from the source
operand to two packed double-precision FP values in the destination
operand.
The destination operand is an XMM register. The source can be either an
XMM register or a 64-bit memory location. If the source is a register,
the input values are in the low quadword.
