Editing Dominator (graph theory) (section)

== Applications ==
Dominators, and dominance frontiers particularly, have applications in [[compiler]]s for computing [[static single assignment form]]. A number of compiler optimizations can also benefit from dominators. The flow graph in this case comprises [[basic block]]s.

Dominators play a crucial role in control flow analysis by identifying the program behaviors that are relevant to a specific statement or operation, which helps in optimizing and simplifying the control flow of programs for analysis.<ref>{{Cite journal |last1=Tamrawi |first1=Ahmed |last2=Kothari |first2=Suresh |date=2018-10-01 |title=Projected control graph for computing relevant program behaviors |url=https://www.sciencedirect.com/science/article/pii/S0167642318301497 |journal=Science of Computer Programming |volume=163 |pages=93–114 |doi=10.1016/j.scico.2018.04.003 |issn=0167-6423}}</ref>

Automatic parallelization benefits from postdominance frontiers. This is an efficient method of computing control dependence, which is critical to the analysis.

Memory usage analysis can benefit from the dominator tree to easily find leaks and identify high memory usage.<ref>{{cite web |url=http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.mat.ui.help%2Fconcepts%2Fdominatortree.html |title=Dominator Tree |author=<!--Staff writer(s); no by-line.--> |orig-year=2008|year=2012 |website=eclipse.org  |publisher=SAP AG and IBM Corporation |access-date=21 June 2013 }}</ref>

In hardware systems, dominators are used for computing signal probabilities for test generation, estimating switching activities for power and noise analysis, and selecting cut points in equivalence checking.<ref>{{cite book
