Line 1:

'''Loop-invariant code''' in an imperative [[Computer programming|programming]] language consists of statements which could be moved to before the loop (if the loop always terminates), or after the loop, without affecting the semantics of the program. As a result it is executed less often, providing a speedup. '''Loop-invariant code motion''' is a [[compiler optimization]] which performs this movement automatically.

Loop-invariant code motion is a compiler optimization which performs this movement automatically.
