.. currentmodule:: llvmlite.binding
.. function:: get_function_cfg(func, show_inst=True) Return a string of the control-flow graph of the function, in DOT format. * If `func` is not a materialized function, the module containing the function is parsed to create an actual LLVM module. * The `show_inst` flag controls whether the instructions of each block are ``printed.functions``.
.. function:: view_dot_graph(graph, filename=None, view=False) View the given DOT source. This function requires the graphviz package. * If view is ``True``, the image is rendered and displayed in the default application in the system. The file path of the output is returned. * If view is ``False``, a ``graphviz.Source`` object is returned. * If view is ``False`` and the environment is in an IPython session, an IPython image object is returned and can be displayed inline in the notebook.
