In compiler theory, dead code elimination is a compiler optimization to remove code which does not affect the program results. Removing such code has two benefits: it shrinks program size, an important consideration in some contexts, and it allows the running program to avoid executing irrelevant operations, which reduces its running time. Dead code includes code that can never be executed (unreachable code), and code that only affects dead variables, that is, variables that are irrelevant to the program.

Famous quotes containing the words dead, code and/or elimination:
“The new always carries with it the sense of violation, of sacrilege. What is dead is sacred; what is new, that is different, is evil, dangerous, or subversive.”
—Henry Miller (1891–1980)
“Hollywood keeps before its child audiences a string of glorified young heroes, everyone of whom is an unhesitating and violent Anarchist. His one answer to everything that annoys him or disparages his country or his parents or his young lady or his personal code of manly conduct is to give the offender a “sock” in the jaw.... My observation leads me to believe that it is not the virtuous people who are good at socking jaws.”
—George Bernard Shaw (1856–1950)
“The kind of Unitarian
Who having by elimination got
From many gods to Three, and Three to One,
Thinks why not taper off to none at all.”
—Robert Frost (1874–1963)
