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:
“There’s something about the dead silence of an office building at night. Not quite real. The traffic down below is something that didn’t have anything to do with me.”
—John Paxton (1911–1985)
“Wise Draco comes, deep in the midnight roll
Of black artillery; he comes, though late;
In code corroborating Calvin’s creed
And cynic tyrannies of honest kings;
He comes, nor parlies; and the Town, redeemed,
Gives thanks devout; nor, being thankful, heeds
The grimy slur on the Republic’s faith implied,
Which holds that Man is naturally good,
And—more—is Nature’s Roman, never to be
scourged.”
—Herman Melville (1819–1891)
“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)
