A.5.51 CVTTPD2DQ: Packed Double-Precision FP to Packed Signed INT32
Conversion with Truncation
CVTTPD2DQ xmm1,xmm2/mem128 ; 66 0F E6 /r [WILLAMETTE,SSE2]
CVTTPD2DQ converts two packed double-precision FP values in the source
operand to two packed single-precision FP values in the destination
operand. If the result is inexact, it is truncated (rounded toward
zero). The high quadword is set to all 0s.
The destination operand is an XMM register. The source can be either an
XMM register or a 128-bit memory location.
