HCC - a Haskell C compiler

An incremental (growing slowly!) compiler for C written in Haskell

Requirements

• Install Haskell via stack

Usage

• Build hcc using stack

stack install

Note that stack install will put the executable on the path whereas stack build will only generate the executable in the ~/.local/bin directory. the executable hcc expects the stack exectuable (hcc-exe) to be on the path.

• To run it, invoke the hcc executable in the project root

./hcc /path/to/source.c

The compiled executable will be in the same directory as the source file, and have the same name (e.g. source in the example above).

Tests

• Unit tests are written using HSpec and can be run using stack

stack test

• Sample programs are included in examples and can be run using test-examples.sh script

./test-examples.sh

These tests compare the executables against gcc.
