Any plans to make LLVM work with Google's new language, Go?

Edward, this is no place for comments like this.

Actually, after chatting with Ian about it, it's more of a case of the FAQ
being poorly worded than them being anti-LLVM.

If you read it closely, it says that LLVM was too slow for 6g, which is their
ultra-fast, non-optimizing implementation based on the Plan9 compilers.  In this
case, the assertion that LLVM is slow is correct: it's definitely slower
than a non-optimizing compiler.  They then later implemented an optimizing
implementation, which they based on GCC because they had a team member (Ian) who
is a GCC expert.

On the positive side, Ian seemed very positive and even encouraging that his
GCCGo frontend might be retargettable from GCC to LLVM, so I wouldn't rule
it out as a possibility if some interested community members stepped up to do
it.
