◆ Run()

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

overridevirtual

Given a module all inner most loops (thetas) are found and unrolled if possible. All nodes in the module are traversed and if a theta is found and is the inner most theta then an attempt is made to unroll it.

Parameters

module	Module where the innermost loops are unrolled
statisticsCollector	Statistics collector for collecting loop unrolling statistics.

Implements jlm::rvsdg::Transformation.
