Detailed Description

template<class RegionTr>
class llvm::RegionBase< RegionTr >

A single entry single exit Region.

A Region is a connected subgraph of a control flow graph that has exactly two connections to the remaining graph. It can be used to analyze or optimize parts of the control flow graph.

A simple Region is connected to the remaining graph by just two edges. One edge entering the Region and another one leaving the Region.

An extended Region (or just Region) is a subgraph that can be transform into a simple Region. The transformation is done by adding BasicBlocks that merge several entry or exit edges so that after the merge just one entry and one exit edge exists.

The Entry of a Region is the first BasicBlock that is passed after entering the Region. It is an element of the Region. The entry BasicBlock dominates all BasicBlocks in the Region.

The Exit of a Region is the first BasicBlock that is passed after leaving the Region. It is not an element of the Region. The exit BasicBlock, postdominates all BasicBlocks in the Region.

A canonical Region cannot be constructed by combining smaller Regions.

Region A is the parent of Region B, if B is completely contained in A.

Two canonical Regions either do not intersect at all or one is the parent of the other.

The Program Structure Tree is a graph (V, E) where V is the set of Regions in the control flow graph and E is the parent relation of these Regions.

Example:

/// A simple control flow graph, that contains two regions.
///
///        1
///       / |
///      2   |
///     / \   3
///    4   5  |
///    |   |  |
///    6   7  8
///     \  | /
///      \ |/       Region A: 1 -> 9 {1,2,3,4,5,6,7,8}
///        9        Region B: 2 -> 9 {2,4,5,6,7}
/// 
You can obtain more examples by either calling

<tt> "opt -regions -analyze anyprogram.ll" </tt>
or
<tt> "opt -view-regions-only anyprogram.ll" </tt>

on any LLVM file you are interested in.

The first call returns a textual representation of the program structure
tree, the second one creates a graphical representation using graphviz.
