A.5.9 ANDNPD: Bitwise Logical AND NOT of Packed Double-Precision FP Values
ANDNPD xmm1,xmm2/mem128 ; 66 0F 55 /r [WILLAMETTE,SSE2]
ANDNPD inverts the bits of the two double-precision floating-point
values in the destination register, and then performs a logical AND
between the two double-precision floating-point values in the source
operand and the temporary inverted result, storing the result in the
destination register.
dst[0-63] := src[0-63] AND NOT dst[0-63],
dst[64-127] := src[64-127] AND NOT dst[64-127].
The destination is an XMM register. The source operand can be either an
XMM register or a 128-bit memory location.
