{{Short description|
The term '''dead code''' has multiple definitions. Some use the term to refer to code (i.e. instructions in memory) which can never be executed at run-time.<ref>[https://www.cs.bu.edu/~hwxi/academic/papers/padl99.pdf Hongwei Xi, Dead Code Elimination through Dependent Types]</ref><ref>[http://www.do178site.com/do178b_questions.php] DO-178B</ref><ref>[[DO-178B]] Wikipedia/DO-178B.</ref>
In some areas of [[computer programming]], '''dead code''' is a section in the [[source code]] of a program which is executed but whose result is never used in any other computation.<ref>[http://doi.acm.org/10.1145/349214.349233 Debray, S.
