◆ Run()

void jlm::llvm::CommonNodeElimination::Run	(	rvsdg::RvsdgModule &	module,
		util::StatisticsCollector &	statisticsCollector
	)

overridevirtual

Perform RVSDG transformation.

Note: This method is expected to be called multiple times. An implementation is required to reset the objects' internal state to ensure correct behavior after every invocation.

Parameters

module	RVSDG module the transformation is performed on.
statisticsCollector	Statistics collector for collecting transformation statistics.

Implements jlm::rvsdg::Transformation.
