dead code

The execution of dead code wastes computation time as its results are never used.

For example, defects in dead code will never result in failures.

Another possibility is to treat pruning as a dead code elimination problem.

Therefore the removal of the dead code may change the output of the program.

Upon completion of the abstract interpretation, instructions which were never reached are marked as dead code.

The efficiency for smart-linking, or dead code elimination, has also been improved.

This is a strength reduction, and also may allow the index variable's definitions to become dead code.

Dead code - code which is executed but whose result is never used.

Historically, dead code elimination was performed using information derived from data-flow analysis.

Some implementations of the C++ standard library have significant amounts of dead code.

Removes instructions that will not affect the behaviour of the program, for example definitions which have no uses, called dead code.

It simultaneously removes some kinds of dead code and propagates constants throughout a program.

Most advanced compilers have options to activate dead code elimination, sometimes at varying levels.

In large programming projects, it is sometimes difficult to recognize and eliminate dead code, particularly when entire modules become dead.

It's just there, just being dead code.

The optimization that removes unreachable code is known as dead code elimination.

A common use of dead code elimination is as an alternative to optional code inclusion via a preprocessor.

Dead code is normally considered dead unconditionally.

This includes removing dead code and rewriting sections that have been modified extensively and no longer work efficiently.

However, it is strictly more powerful than applying dead code elimination and constant propagation in any order or any number of repetitions.

Xizzle: This is now dead code.

Unintended null functions can arise during the development of complex programs, and like dead code, such occurrences indicate serious flaws in program structures.

Thus template code can result in smaller binaries because a compiler is allowed to discard this kind of dead code.

Subsequent dead code elimination removes those calculations and completes the effect (without complicating the strength-reduction algorithm).

Continuing to propagate yields the following (which would likely be further optimized by dead code elimination of both x and y.)
