Detailed Description
RegionNode class - represent nodes inside a region. They can either be a basic block that is not part of any subregion or a subregion.Constructor & Destructor Documentation
| llvm::RegionNode::RegionNode | ( | Region * | r, | |
| BasicBlock * | entry, | |||
| BasicBlock * | exit | |||
| ) | [inline, protected] |
Create the region node. We can only create a regionnode when we create a region.
Member Function Documentation
| BasicBlock* llvm::RegionNode::getBB | ( | ) | const [inline] |
Get the region node as BB no matter which type the regionnode is. If this node is a region node, the function will return its entry.
| const Region* llvm::RegionNode::getItRegion | ( | ) | const [inline] |
getItRegion - Get the region we are iterating over. This is useful when we are iterating in flat mode, because we need to go down the region tree to get the lowest level BB node.
| void llvm::RegionNode::propItRegionTo | ( | RegionNode * | Node | ) | const [inline] |
propItRegionTo - Propagate the region we are iterating to Node, so that we know when to end our iteration in the flat mode.
Member Data Documentation
BasicBlock* llvm::RegionNode::BB [protected] |
The basic block that starts this region node. If this is a BB node, then BB is just the basic block, that this regionnodes represents, otherwise it is the entry of this region. In the BBtoRegionNode map of the parent of this node, BB will always map to this node no matter which kind of node this one is.
