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.

Do basic block parameters mean code locality?

Most modern compilers use some form of SSA for internal representation, which needs some notation for variables whose values can come from more than one source. The classic version uses phi nodes. Basic block parameters are also an option. As I…

Using a locally defined class instead of the one provided by a library/package C# IL Weaving

I have seen stuff like Fody and in fact have been using PropertyChanged which reduces the boilerplate code after implementing the INotifyPropertyChanged interface. I believe it is done by 'weaving the IL' so an idea crossed my mind. The problem is…
