摘要：A method for suppressing prediction of a backward branch instruction used in avector partitioning loop includes detecting the first backward branch instruction thatoccurs after a predicate generating instruction. The predicate generating instruction
generates a predicate vector that is dependent upon a dependency vector where eachelement of the dependency vector indicates whether a data dependency exists betweenelements of a vector instruction. The method also includes receiving an indication of aprediction accuracy of a prediction of the backward branch instruction. If the predictionaccuracy does not satisfy a threshold value, the prediction of the backward branchinstruction is suppressed until the dependency vector on which the predicate-generatinginstruction depends is available.
