*** 40,50 **** --- 40,50 ---- InvocationCounter _backedge_counter; // Incremented before each backedge taken - used to trigger frequencey-based optimizations // NMethod age is a counter for warm methods detection in the code cache sweeper. // The counter is reset by the sweeper and is decremented by some of the compiled // code. The counter values are interpreted as follows: // 1. (HotMethodDetection..INT_MAX] - initial value, no counters inserted ! // 2. (1..HotMethodDetectionLimit) - the method is warm, the counter is used ! // 2. [1..HotMethodDetectionLimit) - the method is warm, the counter is used // to figure out which methods can be flushed. // 3. (INT_MIN..0] - method is hot and will deopt and get // recompiled without the counters int _nmethod_age; int _interpreter_invocation_limit; // per-method InterpreterInvocationLimit
