What is ghc

GHC is a state-of-the-art, open source, compiler and interactive environment for the functional language Haskell. Highlights - GHC supports the entire Haskell 2010 language plus various 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 (check the results on the “Computer Language Benchmarks Game”). - GHC works on several platforms including Windows, Mac, Linux, most varieties of Unix, and several different processor architectures. - GHC has extensive optimisation capabilities, including inter-module optimisation. - GHC compiles Haskell code either directly to native code or using LLVM as a back-end. GHC can also generate C code as an intermediate target for porting to new platforms. The interactive environment compiles Haskell to bytecode, and supports execution of mixed bytecode/compiled programs. - Profiling is supported, both by time/allocation and heap profiling. - GHC comes with core libraries, and thousands more are available on Hackage.
