Expand description

Computes the bitwise AND of 128 bits (representing single-precision (32-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 32-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 32-bit element in the intermediate value is zero, otherwise set `CF` to 0. Return the `ZF` value.
