Я новичок в разборе, и я пытаюсь использовать Pycparser для анализа моего файла c, и я следую инструкции, предварительно обработав файл gcc -E, затем я использовал using_gcc_E_libc.py из папки примера, и я передаю свой файл, и я получилкакой-то вывод, но я не уверен, что так выглядит AST?Если это правильный AST, как я могу найти каждый узел, его зависимость и указатель (местоположение) этого узла?
