C++ (Cpp) myframe Examples

Example #1

File: os_linux_sparc.cpp Project: benbenolson/hotspot_9_mc

frame os::current_frame() {
  intptr_t* sp = StubRoutines::Sparc::flush_callers_register_windows_func()();
  frame myframe(sp, frame::unpatchable,
                CAST_FROM_FN_PTR(address, os::current_frame));
  if (os::is_first_C_frame(&myframe)) {
    // stack is not walkable
    return frame(NULL, frame::unpatchable, NULL);
  } else {
    return os::get_sender_for_C_frame(&myframe);
  }
}

Example #2

File: os_linux_aarch64.cpp Project: nikezheng/lookaside_java-1.8.0-openjdk

frame os::current_frame() {
  intptr_t* fp = _get_previous_fp();
  frame myframe((intptr_t*)os::current_stack_pointer(),
                (intptr_t*)fp,
                CAST_FROM_FN_PTR(address, os::current_frame));
  if (os::is_first_C_frame(&myframe)) {
    // stack is not walkable
    return frame();
  } else {
    return os::get_sender_for_C_frame(&myframe);
  }
