Haskell compiler that produce binary through C language.

Ajhc is a fork of jhc. The jhc is a haskell compiler which aims to produce the most efficient programs possible via whole program analysis and other optimizations.

The jhc is very minimalist in that it does not have a precompiled run time system, but rather generates what is needed as part of the compilation process. However, back ends do have specific run-time representations of data, which can be affected by things like the choice of garbage collector.

Ajhc - arafura-jhc

A fork of jhc. And also a Haskell compiler.

This project is founded by Metasepi Project.

For developing

First, you should use the arafura branch, rather than master branch.

• master branch: Do not touch me, mirror of jhc's darcs repository.
• arafura branch: For developing Ajhc.

You should send patch to jhc, if testing on Ajhc is good.

$ darcs get http://repetae.net/repos/jhc
$ cd jhc/
$ patch -p1 < ~/yourfile.patch
$ darcs record -a
$ darcs send

The command darcs send sends email the patch to jhc author (= John Meacham).

Future plan

• Benchmark (speed, memory size, compare with eLua/mruby/.NET Micro Framework)
• No more depend on Perl (LWP and YAML).
• Port Haskell libraries on haskell-platform to Ajhc.
• Understand jhc's region inference.
• Play with Google Native Client. https://developers.google.com/native-client/
• Write Linux kernel driver with Haskell.
• Get smaller RTS. Benchmark the RTS for running on custom FPGA CPU.
• Start rewritng NetBSD kernel with Ajhc.
