15 A control flow graph (CFG) is a data structure built on top of the
17 stream) abstracting the control flow behavior of a function that is
20 control flow from one basic block to another. The data structures
21 used to represent the control flow graph are defined in
24 In GCC, the representation of control flow is maintained throughout
29 and its release. This way, transfer of information such as data flow,
42 * Maintaining the CFG:: Keeping the control flow graph and up to date.
122 A basic block ends with a control flow instruction or with the last

183 Edges represent possible control flow transfers from the end of some
255 There are various reasons why control flow may transfer from one block
270 may be freely redirected when the flow graph is not in SSA form.
290 exception needs to be handled as control flow instruction. Exception
328 and many computed jumps may have @emph{very} dense flow graphs, so
330 stages of the compilation process, GCC tries to avoid such dense flow

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

512 flow graph and all profile information up-to-date. Reconstruction of
513 the control flow graph after each pass is not an option, since it may be
519 flow. Both representations share as much of the CFG maintenance code
544 iterators provide an integrated abstraction of the flow graph and the

612 It is also possible that a pass has to insert control flow instruction
