Detailed Description

CFGBlock - Represents a single basic block in a source-level CFG.

It consists of:

(1) A set of statements/expressions (which may contain subexpressions). (2) A "terminator" statement (not in the set of statements). (3) A list of successors and predecessors.

Terminator: The terminator represents the type of control-flow that occurs at the end of the basic block. The terminator is a Stmt* referring to an AST node that has control-flow: if-statements, breaks, loops, etc. If the control-flow is conditional, the condition expression will appear within the set of statements in the block (usually the last statement).

Predecessors: the order in the set of predecessors is arbitrary.

Successors: the order in the set of successors is NOT arbitrary. We currently have the following orderings based on the terminator:

Terminator Successor Ordering

if Then Block; Else Block ? operator LHS expression; RHS expression &&, || expression that uses result of && or ||, RHS

But note that any of that may be NULL in case of optimized-out edges.
