I’ve merged many good patches into the main llvmruby branch. We are now officially using LLVM 2.4, compatible with Ruby 1.9 and more complete access to the LLVM API.
Miura Hideki has been making some great progress with his yarv2llvm project. He’s been compiling much more complex stuff and doing some really nice profiling work. I finally got to try it out for myself and it has a few issues running on 64-bit, so I plan on sending some fixes back his way.
