Googling for "LLVM JVM" unearths few interesting things, i.e. a LLVM- based JVM JIT for GCJ apparently maintained by someone at Red Hat.
<http://lists.cs.uiuc.edu/pipermail/llvmdev/2006-April/005579.html> That said, LLVM has all sorts of code analysis and transformation capabilities for its own bytecode format (that are usually used to optimize the code, but it can of course be used for other sorts of code comprehension tasks too), as well as codegen modules for several CPU architectures (to create native object code once you're happy with the optimizations). I see no reason why there couldn't be a codegen module targetting JVM bytecode. LLVM also ships with a C-to-LLVM compiler, so in similar vein, Java-to- LLVM might also be possible. OTOH, C has much less expectations w/ regard to the runtime environment than Java (the language) does, so there might be dragons that way. Attila.
