[edit] Project Goals

ELLCC is a project to combine the Elkhound parser generator and its companion Elsa C/C++ compiler with 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.

[edit] Near Term

• A functional C/C++ compiler based on Elsa.
• Generalized AST (Abstract Syntax Tree) to LLVM IR lowering support.
• Multi-target support (Alpha, ARM, C, C++, CellSPU, IA64, Mips, MSIL, Nios2, PIC16, PowerPC, Sparc, X86, X86_64).
• A C-only release (status).

[edit] Long Term

• A release with C++ support.
• Heterogeneous target support in one compilation.
• Language support for message passing/multi-threading.

[edit] Project Components

• ELLCC - The ELLCC compiler driver framework.
• PW - The preprocessor/configuration file library.
• Elsa - The C/C++ compiler.
• LLVM - The compiler back end.
• Elkhound - The parser generator.
• binutils - The GNU binutils package.
• newlib - The C standard library.
• Insight - The Insight debugger.

[edit] Project Status

• C compilation on the X86 architecture targeting Linux functional.
• Full program compilation and inter-module optimization supported.
• A new preprocessor almost complete.
