[LLVMdev] LLVM-gcc for a new architecture

  Yes, I know that. configure --target=a-b-c will fail because there  
is no such stuff known in gcc. So, what is the answer/consequence? An  
existing gcc back-end for architecture "a" is a precondition for a  
LLVM back-end for architecture "a"?

  Is there another fully working C front-end for LLVM?
