    312 CVTSD2SS and CVTPD2PS Instructions May Not Round to Zero

    Description
    The Convert Scalar Double-Precision Floating Point to Scalar Single-Precision Floating Point (CVTSD2SS) and Convert Packed Double-Precision Floating Point to Packed Single-Precision Floating Point (CVTPD2PS) instructions do not round to zero when the Flush to Zero and Underflow Mask bits (MXCSR bits 15 and 11) are set to 1b and the double-precision operand is less than the smallest single-precision normal number.

    Potential Effect on System

    The conversion result will yield the smallest single-precision normalized number rather than zero. It is not expected that this will result in any anomalous software behavior since enabling flush to zero provides less precise results.

    Suggested Workaround
    None

    Fix Planned
    No
