intermediate representation Most compilers translate the source first to some form of intermediate representation and convert from there into machine code. The intermediate representation is a machine- and languageindependent version of the original source code. Although converting the code twice introduces another step and thus incurs loss in compiler efficiency, use of an intermediate representation provides advantages in increased abstraction. cleaner separation between the front and back ends, adds possibilities for re-targeting/cross- compilation, and works well with many advanced optimization techniquesintermediate representation Most compilers translate the source first to some form of intermediate representation and convert from there into machine code.
