InstructionSource Class

Constructor

InstructionSource()

Methods

add_node	Add a node to the instruction source graph.
add_root	Add a root node to the instruction source graph.
from_isa	Construct an InstructionSource graph from an ISA. The instruction source graph contains more information than the provenance graph in the context, as it connects the instructions to the transforms and architectures that generated them.
get	Retrieve the first instruction source root node with the given instruction ID. Returns default if no such node exists.

add_node

Add a node to the instruction source graph.

add_node(instruction: Instruction, transform: ISATransform | Architecture | None, children: list[int]) -> int

Parameters

Name	Description
instruction Required	<xref:qdk.qre.Instruction> The instruction for this node.
transform Required	<xref:Optional>[<xref:ISATransform | Architecture>] The transform that produced the instruction.
children Required	list[int] Indices of child nodes.

Returns

Type	Description
int	The index of the newly added node.

add_root

Add a root node to the instruction source graph.

add_root(node_id: int) -> None

Parameters

Name	Description
node_id Required	int The index of the node to add as a root.

from_isa

Construct an InstructionSource graph from an ISA.

The instruction source graph contains more information than the provenance graph in the context, as it connects the instructions to the transforms and architectures that generated them.

from_isa(ctx: ISAContext, isa: ISA) -> InstructionSource

Parameters

Name	Description
ctx Required	ISAContext The enumeration context containing the provenance graph.
isa Required	ISA Instructions in the ISA will serve as root nodes in the source graph.

Returns

Type	Description
InstructionSource	The instruction source graph for the estimation result.

get

Retrieve the first instruction source root node with the given instruction ID. Returns default if no such node exists.

get(id: int, default: _InstructionSourceNodeReference | None = None) -> _InstructionSourceNodeReference | None

Parameters

Name	Description
id Required	int The instruction ID to search for.
default	<xref:Optional>[<xref:_InstructionSourceNodeReference>] The value to return if no node with the given ID is found. Default is None. Default value: None

Returns

Type	Description
Optional[<xref:_InstructionSourceNodeReference>]	The first instruction source node with the given instruction ID, or default if no such node exists.
