Dead code
In computer programming, dead code is code in the source code of a program which is executed but whose result is never used in any other computation. The execution of dead code wastes computation time as its results are never used. While the result of a dead computation may never be used, the dead code may raise exceptions or affect some global state, thus removal of such code may change the output of the program and introduce unintended bugs. Compiler optimizations are typically conservative in their approach to dead code removal if there is any ambiguity as to whether removal of the dead code will affect the program output. The programmer may aid the compiler in this matter by making additional use of static and/or inline functions and enabling the use of link-time optimization.
The New Hacker's Dictionary
dead code
Routines that can never be accessed because all calls to them have been removed, or code that cannot be reached because it is guarded by a control structure that provably must always transfer control somewhere else. The presence of dead code may reveal either logical errors due to alterations in the program or significant changes in the assumptions and environment of the program (see also software rot); a good compiler should report dead code so a maintainer can think about what it means. (Sometimes it simply means that an extremely defensive programmer has inserted can't happen tests which really can't happen — yet.) Syn. grunge. See also dead, and The Story of Mel'.
