Errata
Specification Update 69
• FDIV instruction with zero operand value in memory
In addition, an assist event may be counted when DAZ (Denormals-Are-Zeros) and
FTZ (Flush-To-Zero) flags are turned on even though no actual assist occurs.
Implication: The counter value for performance monitoring event FP_ASSIST (11H)
may be larger than expected. The size of the error is dependent on the
number of occurrences of the above condition while the event is active.
Workaround: None identified.
Status: For the steppings affected, see the Summary Tables of Changes.
