Low Level Virtual Machine 1.3 Released

RSpencer writes "The Low Level Virtual Machine project has released version 1.3. There are full release notes available. LLVM is a source-language agnostic toolkit for building compilers, optimizers, and jit or interpreted virtual machines. LLVM provides extensive optimization support, three mid-level IR formats (bytecode, assembly, and C++), three backend targets (x86,Sparc,PPC), full documentation, and a very simple and unique design. This new toolkit approach to compiler related tools is quickly attracting new developers who are making significant contributions to the work. Visit the home page where you can learn all the details. LLVM is funded by the National Science Foundation, MARCO/DARPA, and supported by UIUC's Computer Science department and other developers."

LLVM Progress

[sabre]

LLVM is an active and vital project with a growing user base and active developer community. If you'd like to chat with some of the devs, stop in to the irc channel.

LLVM is a very young project (only 3 years old) but has already made dramatic progress in it's time. Check out the status updates on the left hand side of the main site to see the rate of progress.

Building a full C/C++ compiler is no small feat!

So...now we have various implementations of the Java VM, the .NET VM, Parrot, and LLVM, plus various emulators of real machines, and let's not forget the real machines themselves.

What I would like to know is how they all compare. How fast does a typical program run? How portable is the implementation; how easy can the bytecode be transformed to native code for various architectures? How easy is it to target this machine? How well does the machine cope with various programming languages (esp. Common LISP)? How stable (backward compatible) is the bytecode? What are the licensing terms? Does it communicate with the host system, and how well? Etc...
