获取的堆栈中多了一些runtimeMethod方法

获取的堆栈中多了一些runtimeMethod方法:

<runtime method>.<runtime internal callee-save reference and argument registers method>

bool FetchStackVisitor::VisitFrame() {
  void *method = ArtHelper::GetCurMethodOfVisitor(this);
  auto *artMethod = static_cast<ArtMethod *>(method);
// 按照我的理解, 应该是在这里会过滤runtime Method, 不过目前没有生效
  if (artMethod == nullptr || artMethod->IsRuntimeMethod()) {
    return true;
  }
