Inspecting per-method or per-register-allocation metrics is preferred to a shoot-out of one register allocation algorithm against another. This is because over 80% of methods are compiled with no use of the ‘future-active’ sets, for which a traditional linear scan algorithm may have spent 20% of its time computing intervals (from ...
