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
ParentThe parent of this RegionNode.
EntryThe 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.
isSubRegionIf this RegionNode represents a SubRegion.

Definition at line 151 of file RegionInfo.h.

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.

Definition at line 175 of file RegionInfo.h.

Referenced by llvm::RegionBase< Tr >::getEntry().

◆ 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() [2/5]

BasicBlock * llvm::RegionNodeBase< RegionTraits< Function > >::getNodeAs< BasicBlock > ( ) const
inline

◆ getNodeAs() [3/5]

Region * llvm::RegionNodeBase< RegionTraits< Function > >::getNodeAs< Region > ( ) const
inline

Definition at line 1005 of file RegionInfo.h.

◆ getNodeAs() [4/5]

Definition at line 166 of file MachineRegionInfo.h.

◆ getNodeAs() [5/5]

Definition at line 175 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 167 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.
