ACC: A C Compiler

Overview

An implementation of C89 compiler
The compiler itself is written in C89
Self-hosting
Compiles C source code to assembly language
Uses platform's assembler and linker
Uses platform's libc

Features

C Preprocessor
Integers and floating point numbers
Pointers and arrays
Structs, unions and enumerators
Variadic functions
Function pointers
Multiple diagnostic messages
(Not all of language features are supported yet)

Build

$ make
- Builds acc
$ make test
- Builds acc and runs test
$ make test_all
- Builds acc and runs test
- Builds the second generation compiler using the first compiler
- Builds the third generation compiler using the second compiler
- Runs binary comparison between the second and the third compiler

Platforms

MacOS with clang
