Abstract
A microprocessor includes a prediction unit (PRU) that predicts a sequence of fetch blocks (FBlks) in a program instruction stream and a macro-op (MOP) cache (MOC) that comprises MOC entries (MEs). An ME holds MOPs into which architectural instructions of one or more FBlks are decoded. The PRU receives a detection of a first instance in which execution of an ME caused a need for an abort and in response resets a counter of the ME. Subsequently, the PRU increments the counter when the PRU predicts the ME is present, invalidates the ME in response to detecting a predetermined number of instances in which execution of the ME caused a need for an abort before the counter reaches a threshold, and retains the ME in the MOC if the counter reaches the threshold before detecting the predetermined number of instances in which the ME caused a need for an abort.
