16 A control flow graph (CFG) is a data structure built on top of the
18 stream) abstracting the control flow behavior of a function that is
21 control flow from one basic block to another.  The data structures
22 used to represent the control flow graph are defined in
29 * Maintaining the CFG::    Keeping the control flow graph and up to date.
94 nodes can precede the block note.   A basic block ends by control flow
141 @cindex edge in the flow graph
143 Edges represent possible control flow transfers from the end of some
215 There are various reasons why control flow may transfer from one block
230 may be freely redirected when the flow graph is not in SSA form.

288 and many computed jumps may have @emph{very} dense flow graphs, so
290 stages of the compilation process, GCC tries to avoid such dense flow

440 The probability that control flow arrives via a given edge to its

470 flow graph and all profile information up-to-date.  Reconstruction of
471 the control flow graph after each pass is not an option, since it may be
