Code motion
GENERIC TERM FOR COMPILER OPTIMIZATION
Draft:Code motion; Code hoisting; Code sinking
In computer science, code motion, also known as code hoisting, code sinking, loop-invariant code motion, or code factoring, is a blanket term for any process that moves code within a program for performance or size benefits, and is a common optimization performed in most optimizing compilers. It can be difficult to differentiate between different types of code motion, due to the inconsistent meaning of the terms surrounding it.
