  2. Control-flow graph - Wikipedia

    en.wikipedia.org/wiki/Control-flow_graph

    In computer science, a control-flow graph (CFG) is a representation, using graph notation, of all paths that might be traversed through a program during its execution. The control-flow graph was discovered by Frances E. Allen , [ 1 ] who noted that Reese T. Prosser used boolean connectivity matrices for flow analysis before.

  3. Control-flow analysis - Wikipedia

    en.wikipedia.org/wiki/Control-flow_analysis

    In computer science, control-flow analysis (CFA) is a static-code-analysis technique for determining the control flow of a program. The control flow is expressed as a control-flow graph (CFG). For both functional programming languages and object-oriented programming languages , the term CFA, and elaborations such as k -CFA, refer to specific ...

  4. Control flow - Wikipedia

    en.wikipedia.org/wiki/Control_flow

    In computer science, control flow (or flow of control) is the order in which individual statements, instructions or function calls of an imperative program are executed or evaluated. The emphasis on explicit control flow distinguishes an imperative programming language from a declarative programming language.

  5. Static single-assignment form - Wikipedia

    en.wikipedia.org/wiki/Static_single-assignment_form

    An example control-flow graph, fully converted to SSA. Now, the last block can simply use y 3, and the correct value will be obtained either way. A Φ function for x is not needed: only one version of x, namely x 2 is reaching this place, so there is no problem (in other words, Φ(x 2,x 2)=x 2). Given an arbitrary control-flow graph, it can be ...

  6. Essential complexity - Wikipedia

    en.wikipedia.org/wiki/Essential_complexity

    Essential complexity is a numerical measure defined by Thomas J. McCabe, Sr., in his highly cited, 1976 paper better known for introducing cyclomatic complexity.McCabe defined essential complexity as the cyclomatic complexity of the reduced CFG (control-flow graph) after iteratively replacing (reducing) all structured programming control structures, i.e. those having a single entry point and a ...

  7. Dominator (graph theory) - Wikipedia

    en.wikipedia.org/wiki/Dominator_(graph_theory)

    Corresponding dominator tree of the control flow graph. In computer science, a node d of a control-flow graph dominates a node n if every path from the entry node to n must go through d. Notationally, this is written as d dom n (or sometimes d ≫ n). By definition, every node dominates itself. There are a number of related concepts:

  9. EiffelStudio - Wikipedia

    en.wikipedia.org/wiki/EiffelStudio

    Code analyzer is a Rule-based static code analysis tool which operates both from an embedded mode within EiffelStudio and from command line. It utilizes the abstract syntax tree (AST) produced by the Eiffel compiler and then generates a control-flow graph (CFG), which is computed by a module of code in the tool. The CFG and AST are then visited ...
