If you've ever tried to even read the instructions for building llvm-gcc (much less try to build it), you understand why this is good news.
Sounds like gcc has gained a plugin architecture, and the llvm folks are putting together a plugin, 'DragonEgg', that uses LLVM as the back end.
Why do I care about this?
1) Clang still does not support lexical functions, which are critically important to Irken's performance.
2) The version of llvm-gcc distributed with Apple's XCode uses an older version of llvm that implements the address-of-label extension with a hack so horrible I would be embarrassed to describe it to you.
