ELLCC - The Embedded LLVM Compiler Collection

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, Standalone, ...
  
• A complete test environment (described in Target Support) that allows automatic unit and integration testing of the run-time environment and complete executables.
• Support of a wide variety of target processors.
  

Components

• ecc - The ELLCC C/C++ compiler. This is a single executable with gcc compatible options that can generate code for all the targets.
  
• binutils - The GNU binutils package. This package provides assemblers for each of the targeted processors, a linker and other utilities (objcopy, nm, etc.).
  
• libecc - The C standard library based on the musl standard C library and the LLVM project's compiler-rt. This package provides a complete run-time environment for Linux with all the source code with a BSD or BSD-like license.
  
• The GDB debugger. The provided build scrips build a version of GDB that supports all the targets with a single executable.
  
• The QEMU emulator provides a test execution environment that can run code for each of the targets. Linux user space programs and standalone or bare-metal programs for all targets can be run, tested, and debugged using the emulator.
