Questions tagged [intermediate-language]

An intermediate language, in compiler design, is a low-level language that typically resembles an idealized assembly language, often a textual representation of bytecode for a virtual machine. For .NET's CIL, use the [cil] tag.

An intermediate language, in compiler design, is a translation stage after the syntax tree and before the machine code. The term is usually used for final stages of the translation, after high-level optimizations have been performed, but at a stage when the translation is still independent of the target machine.

In particular, “intermediate language” often means a low-level, assembly-like language for a virtual machine such as the JVM, .NET, Prolog's WAM, etc.

For example, the .NET Common Intermediate Language is the assembly language for the virtual machine that is the target of and other compilers.
