Dealing with Inlining

In an adaptive system, inlining might be applied on a few hot methods. We capture these events as follows. When a callee is inlined into a caller by an optimizing JIT compiler, the call edge from the caller to callee is added to the call graph unconditionally. This is a conservative solution without runtime overhead. Since an inlined call site is likely executed before its caller becomes hot, the number of added superfluous edges is modest.
