Method Detail

checkLoopOrder

protected static boolean checkLoopOrder(Iterable<Loop<Block>> loops)

Checks that loops are ordered such that outer loops appear first.

loop

public LoopEx loop(Loop<Block> loop)

Get the LoopEx corresponding to loop.

loop

public LoopEx loop(LoopBeginNode loopBegin)

Get the LoopEx corresponding to loopBegin.

loops

public List<LoopEx> loops()

Get all loops.

Returns:

all loops.

outerFirst

public List<LoopEx> outerFirst()

Get all loops, with outer loops ordered before inner loops.

Returns:

all loops, with outer loops first.

innerFirst

public List<LoopEx> innerFirst()

Get all loops, with inner loops ordered before outer loops.

Returns:

all loops, with inner loops first.

nonCountedLoops

public List<LoopEx> nonCountedLoops()

Get all non-counted loops. Counted loop detection must have already been performed with LoopsData.detectCountedLoops().

Returns:

all loops that are not counted.

countedLoops

public List<LoopEx> countedLoops()

Get all counted loops. Counted loop detection must have already been performed with LoopsData.detectCountedLoops().

Returns:

all loops that are counted.

detectCountedLoops

public void detectCountedLoops()

Perform counted loop detection for all loops which have not already been checked.

getCFG

public ControlFlowGraph getCFG()

Get the CFG this loops data is calculated from.

getInductionVariable

public InductionVariable getInductionVariable(ValueNode value)

Get information for an induction variable, or null if not found in one of the loops.

deleteUnusedNodes

public void deleteUnusedNodes()

Deletes any nodes created within the scope of this object that have no usages.
