llpython.byte_control

class llpython.byte_control.ControlFlowBuilder

Visitor responsible for traversing a bytecode flow object and building a control flow graph (CFG).

The primary purpose of this transformation is to create a CFG, which is used by later transformers for dataflow analysis.

visit(flow, nargs=0, *args, **kws)

Given a bytecode flow, and an optional number of arguments, return a llpython.control_flow.ControlFlowGraph instance describing the full control flow of the bytecode flow.

llpython.byte_control.build_cfg(func)

Given a Python function, create a bytecode flow, visit the flow object, and return a control flow graph.
