Predicted null updates

A computer-implemented method of facilitating processing within a computing environment, the computer-implemented method comprising:

• obtaining a request to set a floating point control;
• based on obtaining the request, performing a read and set floating point state with predicted fast null update operation, the predicted fast null update operation predicting whether to invoke a floating point status update with a fast null update operation;
• invoking, based on predicting that the floating point status update with the fast null update operation is to be invoked, the floating point status update with the fast null update operation;
• and
• performing the invoked floating point status update with the fast null update operation, the performing comprising:
• determining whether there is a predicted null update of the floating point control, the determining using predictor logic;
• determining, at least in part, based on there being a predicted null update of the floating point control as indicated by the predictor logic, whether a value of the floating point control indicated by the request is equal to a value of the floating point control stored in a selected location;
• and
• based on determining the value of the floating point control indicated by the request is equal to the value of the floating point control stored in the selected location, updating the predictor logic to indicate that the predicted null update is correct and that a null update of the floating point control has been successful, without setting the floating point control pursuant to the request to set the floating point control.
