Program Counter register values for a Java program

Is it possible to obtain the program counter (PC) register values of a running Java application?

有帮助吗?

解决方案

It depends on how you want to go about it. For example, if via the JVM Tool Interface, there is an exposed function named GetFrameLocation. This should be equivalent to the program counter.

jvmtiEnv *penv;
...
jmethodID cur_method;
jlocation cur_loc;
(*penv)->GetFrameLocation(0, 0, &cur_method, &cur_loc);
