A.5.47 CVTSI2SD: Signed INT32 to Scalar Double-Precision FP Conversion
CVTSI2SD xmm,r/m32 ; F2 0F 2A /r [WILLAMETTE,SSE2]
CVTSI2SD converts a signed doubleword from the source operand to a
double-precision FP value in the low quadword of the destination
operand. The high quadword is left unchanged.
The destination operand is an XMM register. The source can be either a
general purpose register or a 32-bit memory location.
