  2. Test-driven development - Wikipedia

    en.wikipedia.org/wiki/Test-driven_development

    Because no more code is written than necessary to pass a failing test case, automated tests tend to cover every code path. For example, for a TDD developer to add an else branch to an existing if statement, the developer would first have to write a failing test case that motivates the branch. As a result, the automated tests resulting from TDD ...

  3. Profile-guided optimization - Wikipedia

    en.wikipedia.org/wiki/Profile-guided_optimization

    Rather than programmer-supplied frequency information, profile-guided optimization uses the results of profiling test runs of the instrumented program to optimize the final generated code. [5] [6] [7] The compiler accesses profile data from a sample run of the program across a representative input set. The results indicate which areas of the ...

    Profiling is achieved by instrumenting either the program source code or its binary executable form using a tool called a profiler (or code profiler). Profilers may use a number of different techniques, such as event-based, statistical, instrumented, and simulation methods.

    A code searching tool with an emphasis on finding software bugs. Search patterns are written in a query language which can search the AST and graphs (CFG, DFG, etc.) of supported languages. A plugin is available for Visual Studio. ConQAT (retired) 2015-02-01 Yes; ASL 2: Ada C#, C++ Java JavaScript — — ABAP

    en.wikipedia.org/wiki/Pathfinding

    On the high-level layer, the path between the clusters is planned. After the plan was found, a second path is planned within a cluster on the lower level. [9] That means, the planning is done in two steps which is a guided local search in the original space.

  7. Code motion - Wikipedia

    en.wikipedia.org/wiki/Code_motion

    A diagram depicting an optimizing compiler removing a potentially useless call to assembly instruction "b" by sinking it to its point of use. Code Sinking, also known as lazy code motion, is a term for a technique that reduces wasted instructions by moving instructions to branches in which they are used: [1] If an operation is executed before a branch, and only one of the branch paths use the ...

  9. Interprocedural optimization - Wikipedia

    en.wikipedia.org/wiki/Interprocedural_optimization

    Whole program optimization (WPO) is the compiler optimization of a program using information about all the modules in the program. Normally, optimizations are performed on a per module, "compiland", basis; but this approach, while easier to write and test and less demanding of resources during the compilation itself, does not allow certainty about the safety of a number of optimizations such ...
