A.5.45 CVTSD2SI: Scalar Double-Precision FP to Signed INT32 Conversion
CVTSD2SI reg32,xmm/mem64 ; F2 0F 2D /r [WILLAMETTE,SSE2]
CVTSD2SI converts a double-precision FP value from the source operand to
a signed doubleword in the destination operand.
The destination operand is a general purpose register. The source can be
either an XMM register or a 64-bit memory location. If the source is a
register, the input value is in the low quadword.
