REGISTER_KERNEL_BUILDER 原理求教

hi，大牛最近在看tensorflow的代码，但是在看
REGISTER_KERNEL_BUILDER 注册OP的时候发现很困惑

‌#define REGISTER_KERNEL_BUILDER(kernel_builder, ...) \
  REGISTER_KERNEL_BUILDER_UNIQ_HELPER(__COUNTER__, kernel_builder, __VA_ARGS__)

‌#define REGISTER_KERNEL_BUILDER_UNIQ_HELPER(ctr, kernel_builder, ...) \
  REGISTER_KERNEL_BUILDER_UNIQ(ctr, kernel_builder, __VA_ARGS__)

‌#define REGISTER_KERNEL_BUILDER_UNIQ(ctr, kernel_builder, ...)          \
  static ::tensorflow::kernel_factory::OpKernelRegistrar                \
      registrar__body__##ctr##__object(                                 \
          SHOULD_REGISTER_OP_KERNEL(#__VA_ARGS__)                       \
              ? ::tensorflow::register_kernel::kernel_builder.Build()   \
              : nullptr,                                                \
          #__VA_ARGS__, [](::tensorflow::OpKernelConstruction* context) \
                            -> ::tensorflow::OpKernel* {                \
                              return new __VA_ARGS__(context);          \
                            });

对于registrar__body__##ctr##__object这个通篇代码都找不到实现啊，能帮忙解答吗，多谢

请问关于TF函数调用图是这么抓取的

在学习TF(Tensorflow)节点布放、Session、图时比较想知道函数调用情况，但不知道怎么抓取，求教？
