Constructor & Destructor Documentation

RegionNodeBase() [1/2]

template<class Tr >

llvm::RegionNodeBase< Tr >::RegionNodeBase ( RegionT *  Parent, BlockT *  Entry, bool  isSubRegion = false  )

inlineprotected

Create a RegionNode.

Parameters

Parent	The parent of this RegionNode.
Entry	The entry BasicBlock of the RegionNode. If this RegionNode represents a BasicBlock, this is the BasicBlock itself. If it represents a subregion, this is the entry BasicBlock of the subregion.
isSubRegion	If this RegionNode represents a SubRegion.

Member Function Documentation

getEntry()

template<class Tr >

BlockT * llvm::RegionNodeBase< Tr >::getEntry ( ) const

inline

Get the entry BasicBlock of this RegionNode.

If this RegionNode represents a BasicBlock this is just the BasicBlock itself, otherwise we return the entry BasicBlock of the Subregion

Returns

The entry BasicBlock of this RegionNode.

getNodeAs() [1/5]

template<class Tr >

template<class T >

T * llvm::RegionNodeBase< Tr >::getNodeAs ( ) const

inline

Get the content of this RegionNode.

This can be either a BasicBlock or a subregion. Before calling getNodeAs() check the type of the content with the isSubRegion() function call.

Returns

The content of this RegionNode.

getNodeAs() [5/5]

MachineRegion * llvm::RegionNodeBase< RegionTraits< MachineFunction > >::getNodeAs< MachineRegion > ( ) const

inline

Definition at line 120 of file MachineRegionInfo.h.

getParent()

template<class Tr >

RegionT * llvm::RegionNodeBase< Tr >::getParent ( ) const

inline

Get the parent Region of this RegionNode.

The parent Region is the Region this RegionNode belongs to. If for example a BasicBlock is element of two Regions, there exist two RegionNodes for this BasicBlock. Each with the getParent() function pointing to the Region this RegionNode belongs to.

Returns

Get the parent Region of this RegionNode.

Definition at line 164 of file RegionInfo.h.

isSubRegion()

template<class Tr >

bool llvm::RegionNodeBase< Tr >::isSubRegion ( ) const

inline

Is this RegionNode a subregion?

Returns

True if it contains a subregion. False if it contains a BasicBlock.
