The goal is threefold: a) Implement more efficient instrumentation along the lines of [Ball94]. b) Implement and experiment with heuristic estimators as proposed in [Wu94]. c) Make profile information available in the backend machinery. We have a preliminary patch that achieves this by maintaining profiles during instruction selection and CFG modifications. This might be useful for several backend passes such as register allocation or if- conversion. We also...
