The ELLCC project is supported by Pennington Software

ELLCC is a project to using Clang and the LLVM (Low Level Virtual Machine) compiler infrastructure. The primary emphasis of the ELLCC project is to create an easy to use multi-target cross compilation environment for embedded systems.

QEMU is used for cross-platform testing. Programs are built for the target as a Linux user space program and run under QEMU for testing purposes.

ELLCC is in a pre-release state. Some targets are farther along than others. Not for the unhardy!

Goals

A functional C/C++ compiler based on Clang (ecc)
Multi-target support: ARM, i386, Microblaze, Mips, Nios2^[2], PowerPC, PowerPC64, Sparc^[1] and X86_64
Multi-OS support: Linux, NetBSD, Standalone, ...
Notes

Components

ecc - The ELLCC C/C++ compiler
binutils - The GNU binutils package
libecc - The C standard library based on the NetBSD standard C library and the LLVM project's compiler-rt
The GDB debugger
The QEMU emulator
