The Glasgow Haskell Compiler (GHC) is a native or machine code compiler for the functional programming language Haskell. [5] It provides a cross-platform software environment for writing and testing Haskell code and supports many extensions, libraries, and optimisations that streamline the process of generating and executing code.
Jhc, a Haskell compiler written by John Meacham, emphasizes speed and efficiency of generated programs and exploring new program transformations. Ajhc is a fork of Jhc. The Utrecht Haskell Compiler (UHC) is a Haskell implementation from Utrecht University. [49] It supports almost all Haskell 98 features plus many experimental extensions.
Once they had improved the compiler to the point where it could compile its own source code, it was self-hosting. [9] The compiler as it exists on the standard compiler tape is a machine language program that was obtained by having the S-expression definition of the compiler work on itself through the interpreter. —

The term comes from the specification for Common Lisp, which explicitly refers to the programming language feature enabling for inter-language calls as such; [citation needed] the term is also often used officially by the interpreter and compiler documentation for Haskell, [1] Rust, [2] PHP, [3] Python, and LuaJIT [4] [5]: 35 . [6]
Different languages compile into a shared runtime. A virtual machine (VM) is a specialised intermediate language that several different languages compile down to. Languages that use the same virtual machine can interoperate, as they will share a memory model and compiler and thus libraries from one language can be re-used for others on the same VM.
Hugs deviates from the Haskell 98 specification [2] in several minor ways. [3] For example, Hugs does not support mutually recursive modules. A list of differences exists. [4] The Hugs prompt is a Haskell read–eval–print loop (REPL). It accepts expressions for evaluation, but not module, type, or function definitions.
In computing, inline expansion, or inlining, is a manual or compiler optimization that replaces a function call site with the body of the called function. Inline expansion is similar to macro expansion, but occurs during compilation, without changing the source code (the text), while macro expansion occurs prior to compilation, and results in different text that is then processed by the compiler.
