A.5.50 CVTSS2SI: Scalar Single-Precision FP to Signed INT32 Conversion
CVTSS2SI reg32,xmm/mem32 ; F3 0F 2D /r [KATMAI,SSE]
CVTSS2SI converts a single-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 32-bit memory location. If the source is a
register, the input value is in the low doubleword.
