The Jhc Haskell Compiler
Jhc is a haskell compiler that aims to produce the most efficient programs possible via whole program analysis and other optimizations. The compiler needs GHC 6.10.4 or later to be compiled; it cannot be compiled on Windows systems.
Go to the Jhc homepage for a tarball. It is also possible to install an older version with cabal-install:
cabal install jhc
