ErLLVM: High-Performance Erlang For LLVM

Developers behind ErLLVM, an LLVM back-end for supporting high-performance Erlang, have called upon this code to be included in mainline LLVM.

Developers out of the National Technical University of Athens Greece have written an LLVM back-end for high-performance ErLang (HiPE) with the native code compiler of Erlang/OTP. The ErLLVM back-end is currently targeting x86 and x86_64 architectures with work on bringing it to ARM also being underway. The ErLLVM implementation is also ABI compatible with the Erlang Runtime System. The developers believe it has now reached "a complete and robust state" so they would like to include this back-end in upstream LLVM.

The patches were submitted on the LLVM mailing list this Saturday. So far there's been no LLVM developers commenting on this ErLLVM back-end. Tomorrow the LLVM SVN code-base is being branched for next month's LLVM 3.1 release so this Erlang implementation would likely not arrive until at least LLVM 3.2.

On another LLVM back-end note, the AMD R600 LLVM back-end also hasn't been pulled into the LLVM code-base, so that too will be off the radar until at least LLVM 3.2 later in the year. With the Southern Islands Gallium3D pull this week, Tom Stellard did end up pushing this R600 LLVM back-end into the Mesa repository, at least temporarily.
