Objective-C in the FreeBSD Kernel progress

[David Chisnall]

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.
