- class ContainsInstruction(*args, **kwargs)[código fonte]¶
An analysis pass to detect if the DAG contains a specific instruction.
This pass takes in a single instruction name for example
'delay'and will set the property set
Trueif the DAG contains that instruction and
Falseif it does not.
instruction_name (str | Iterable[str]) – The instruction or instructions to check are in the DAG. The output in the property set is set to
contains_prefixed on each value for this parameter.
recurse (bool) – if
True(default), then recurse into control-flow operations.
Return the name of the pass.
Run the ContainsInstruction pass on dag.
Check if the pass is an analysis pass.
If the pass is an AnalysisPass, that means that the pass can analyze the DAG and write the results of that analysis in the property set. Modifications on the DAG are not allowed by this kind of pass.
Check if the pass is a transformation pass.
If the pass is a TransformationPass, that means that the pass can manipulate the DAG, but cannot modify the property set (but it can be read).
