In computer science, an intermediate language is the language of an abstract machine designed to aid in the analysis of computer programs. The term comes from their use in compilers, where a compiler first translates the source code of a program into a form more suitable for code-improving transformations, as an intermediate step before generating object or machine code for a target machine. The design of an intermediate language typically differs from that of a practical machine language in three fundamental ways: Computer science, or computing science, is the study of the theoretical foundations of information and computation and their implementation and application in computer systems. ...

- Each instruction represents exactly one fundamental operation; e.g. "shift-add" addressing modes common in microprocessors are not present.
- Control flow information may not be included in the instruction set.
- The number of registers available may be large, even limitless.
A popular format for intermediate languages is three address code. Microprocessors, including an Intel 80486DX2 and an Intel 80386 A microprocessor (abbreviated as µP or uP) is an electronic computer central processing unit (CPU) made from miniaturized transistors and other circuit elements on a single semiconductor integrated circuit (IC) (aka microchip or just chip). ...

A variation in the meaning of this term, is those languages used as an intermediate language by some high-level programming languages which do not output object or machine code, but output the intermediate language only, to submit to a compiler for such language, which then outputs finished object or machine code. This is usually done to gain optimization much as treated above, or portability by using an intermediate language that has compilers for many processors and operating systems, such as C. Languages used for this fall in complexity between high-level languages and low-level languages, such as assembly languages. A high-level programming language is a programming language that, in comparison to low-level programming languages, may be more abstract, easier to use, or more portable across platforms. ...

C is used as an intermediate language by many programming languages including Eiffel, Sather, Esterel; some dialects of Lisp (Lush, Gambit), Haskell (Glasgow Haskell Compiler); Squeak's C-subset Slang, and others. Variants of C have been designed to provide C's features as a portable assembly language, including one of the two languages called C--, the C Intermediate Language and the Low Level Virtual Machine.
