GCC and LLVM collaboration
Sidenote: the GNU Tools Cauldron was a very enjoyable event with many interesting talks. I've summarised many of the ones I attended here: http://llvmweekly.org/issue/29Do take a look at my LLVM Weekly newsletter http://llvmweekly.org/ (and/or follow @llvmweekly on Twitter) if you're interested in keeping up to date with LLVM developments.If anybody wants to get stuck in to an interesting and meaningful open source project such as gcc/clang, things like the compiler driver (command line parsing+invoking the steps in the compilation process) are accessible to someone who can deal with gnarly code but perhaps isn't a compiler expert, and I think it's fair to see could benefit a lot from careful refactoring and better testing in both GCC and Clang.
