Hi Everyone,
Those of you who came to the DevSummit will have met Krystof already. For those that didn't, he's my summer intern and has been working on putting an Objective-C runtime in the FreeBSD kernel. The runtime is largely based on the GNUstep runtime, but with some legacy stuff stripped out and with some cleanups to the ABI (since we don't need to be backwards compatible with any existing Objective-C code). He's also been hacking on clang to support this ABI.
As of this week, he managed to get libunwind running in the kernel as well, so you can even throw exceptions from Objective-C in the kernel (this is required for getting Smalltalk to work, as we use exceptions for non-local returns). The code still needs some cleanup, but it's quite promising.
