Abstract
Systems and methods are disclosed for macro-op fusion. Sequences of macro-ops that include a control-flow instruction are fused into single micro-ops for execution. The fused micro-ops may avoid the use of control-flow instructions, which may improve performance. A fusion predictor may be used to facilitate macro-op fusion.
