Small C Compiler generating ELF executable for Arm architecture

AMaCC = Another Mini ARM C Compiler

Introduction

AMaCC is built from scratch, supporting ARM architecture. There are 3 execution modes AMaCC implements:

• Just-in-Time compiler (JITC) for ARM backend
• Generate valid Executable and Linkable Format (ELF) executables
• Interpreter-only execution

Compatibility

AMaCC is capable of compiling C source files written in the following syntax:

• data types: char, int, struct, and pointer
• condition statements: if, while, for, switch, return, and expression

Prerequisites

• Code generator in AMaCC relies on several GNU/Linux behaviors, and it is necessary to have ARM/Linux installed in your build environment.

• Install Linaro ARM Toolchain

  • Check "Latest Linux Targeted Binary Toolchain Releases"
  • Select arm-linux-gnueabihf (32-bit Armv7-a, hard-float, little-endian)

• Install QEMU for ARM user emulation

sudo apt-get install qemu-user

Running AMaCC

Run make check and you should see this:

[ C to IR translation          ] Passed
[ JIT compilation + execution  ] Passed
[ ELF generation               ] Passed
[ nested/self compilation      ] Passed

Acknowledgements

AMaCC is based on the infrastructure of c4.
