Method testz_pd
testz_pd(v128, v128)
Compute the bitwise AND of 128 bits (representing double-precision (64-bit) floating-point elements) in a and b, producing an intermediate 128-bit value, and set ZF to 1 if the sign bit of each 64-bit element in the intermediate value is zero, otherwise set ZF to 0. Compute the bitwise NOT of a and then AND with b, producing an intermediate value, and set CF to 1 if the sign bit of each 64-bit element in the intermediate value is zero, otherwise set CF to 0. Return the ZF value.
