pyquil.control_flow_graph module

Classes that represent the control flow graph of a Quil program.

class pyquil.control_flow_graph.BasicBlock(cls, /, instance)

Bases: BasicBlock

Represents a basic block in the Program.

Most functionality is implemented by the quil package. See the quil BasicBlock documentation for documentation and available methods.

instructions() → list[AbstractInstruction]

terminator() → AbstractInstruction | None

class pyquil.control_flow_graph.ControlFlowGraph(cls, /, instance)

Bases: ControlFlowGraph

Representation of a control flow graph (CFG) for a Quil program.

The CFG is a directed graph where each node is a basic block and each edge is a control flow transition between two basic blocks.

This class should not be initialized directly. Use :py:meth:~pyquil.quil.Program.control

flow_graph` to get a CFG for a program.

Most functionality is implemented by the quil package. See the quil ControlFlowGraph documentation for available methods.

basic_blocks() → list[BasicBlock]

Return a list of all the basic blocks in the control flow graph, in order of definition.
