Expand description

Test packed half-precision (16-bit) floating-point elements in a for special categories specified by imm8, and store the results in mask vector k using zeromask k (elements are zeroed out when the corresponding mask bit is not set). imm can be a combination of:

    0x01 // QNaN
    0x02 // Positive Zero
    0x04 // Negative Zero
    0x08 // Positive Infinity
    0x10 // Negative Infinity
    0x20 // Denormal
    0x40 // Negative
    0x80 // SNaN
