摘要： A method and system for analyzing a virtual function. In one embodiment, the present invention determines whether a virtual table exists for a virtual function, and determines a call type for the virtual function. In the present embodiment, provided the virtual table is located, the present invention replaces an existing address for the virtual function with a new address such that the new address points to instrumentation code. In this embodiment, upon a call to the virtual function, the present invention loads the new address from the virtual table such that execution is directed to the instrumentation code. The present embodiment continues execution and executes the instrumentation code such that control is delivered to the instrumentor.

摘要： A method and a system for examining an inlined function using a performance analysis tool are described. An inlined function is identified in computer code. Upon identification of the inlined function, and for example in response to executing a breakpoint associated with the inlined function, a performance analysis tool is used to perform desired task on the inlined function.
