The following are examples of control-flow graphs −If then else − One path is taken when the condition is true (the "then" part), and another path is taken when the condition is false (the "else" part).while
control flow graph Control Flow Graphs Nodes Statements or Basic Blocks (Maximal sequence of code with branching only allowed at end) Edges Possible transfer of control Example:if P then S1 else S2 S3 P S1S2 S3 CFG P predecessor of S1 and S2 S1, S2 sucessors of P Finding Basic Blocks ...
These are mentioned tantalisingly in the whitepaper, and code for them seems to be present (although omitted from the docs). It's not clear at all (to me at least) how to use Enter/Leave/NextIteration to actually construct a loop -- an e...
let hours = 12 let hourInterval = 3 for tickMark in stride(from: 3, through: hours, by: hourInterval) { // render the tick mark every 3 hours (3, 6, 9, 12) } The examples above use a for-in loop to iterate ranges, arrays, dictionaries, and strings. However, you can use ...
Complete samples are available in theCUDA samples repository. The next section runs through some examples to show what you can do with conditional nodes. Conditional IF nodes The body graph of an IF node will be executed once if the condition is non-zero whenever the IF node is evaluated. ...
REPEAT… UNTIL— Loop until the predicate is true. RETURN— Terminate the run of the current scope and return to the calling scope. WHILE— Continue looping while the condition returns TRUE. Examples The following example demonstrates a solution for running differ...
Some examples of such technical solutions include expert system and knowledge-base-equipped controllers, multiagent behavior-based controllers, and game-theoretic controllers. In Fig. 15, the three major theoretical techniques typical for systems with intelligent controllers are demonstrated to be various ...
It is possible to find such rewriting schemes for a loop without knowing the exact form of the loop. This is best shown by two examples. Havoc Abstraction. Let us look at the rather simple loop abstraction that served as example in Sect. 1, which we call havoc abstraction. Here we ...
StartVal) return nullptr; // Make the new basic block for the loop header, inserting after current // block. Function *TheFunction = Builder->GetInsertBlock()->getParent(); BasicBlock *PreheaderBB = Builder->GetInsertBlock(); BasicBlock *LoopBB = BasicBlock::Create(*TheContext, "loop"...
Control flow analysis (CFA) is a static program analysis for determining the control flow of a program, which is usually expressed as a control flow graph (CFG). Exception handling constructs induce additional control flow, which we call exceptional control flow, over normal control flow of progr...
