GHC

The Glasgow Haskell Compiler

GHC is a state-of-the-art, open source, compiler and interactive environment for the functional language Haskell. Highlights:

GHC supports the entire Haskell 98 language plus a wide variety of extensions.
GHC has particularly good support for concurrency and parallelism, including support for Software Transactional Memory (STM).
GHC generates fast code, particularly for concurrent programs. Take a look at GHC’s performance on The Computer Language Benchmarks Game, and some comments on Haskell by the current organiser of the shootout, Brent Fulgham.
GHC works on several platforms including Windows and most varieties of Unix, and several different processor architectures. There are detailed instructions for porting GHC to a new platform.
GHC has extensive optimisation capabilities, including inter-module optimisation.
GHC compiles Haskell code either by using an intermediate C compiler (GCC), or by generating native code on some platforms. The interactive environment compiles Haskell to bytecode, and supports execution of mixed bytecode/compiled programs.
Profiling is supported, both by time/allocation and various kinds of heap profiling.
GHC comes with a wide range of libraries.
