C++ (Cpp) JavaThread::last_frame Examples

Example #1

File: interfaceSupport.cpp Project: gaoxiaojun/dync

void InterfaceSupport::verify_last_frame() {
  JavaThread* thread = JavaThread::current();
  ResourceMark rm(thread);
  RegisterMap reg_map(thread);
  frame fr = thread->last_frame();
  fr.verify(&reg_map);
}

Example #2

File: c1_Runtime1.cpp Project: ericbbcc/hotspot

static bool caller_is_deopted() {
  JavaThread* thread = JavaThread::current();
  RegisterMap reg_map(thread, false);
  frame runtime_frame = thread->last_frame();
  frame caller_frame = runtime_frame.sender(&reg_map);
  assert(caller_frame.is_compiled_frame(), "must be compiled");
  return caller_frame.is_deoptimized_frame();
}

Example #3

File: c1_Runtime1.cpp Project: ericbbcc/hotspot

// Stress deoptimization
static void deopt_caller() {
  if ( !caller_is_deopted()) {
    JavaThread* thread = JavaThread::current();
    RegisterMap reg_map(thread, false);
    frame runtime_frame = thread->last_frame();
    frame caller_frame = runtime_frame.sender(&reg_map);
    Deoptimization::deoptimize_frame(thread, caller_frame.id());
    assert(caller_is_deopted(), "Must be deoptimized");
  }
