[LLVMdev] C Backend Ressurected

[Bruce Hoult]

I don't know how good it is, but the applications seem obvious. e.g.
compiling programs in any of a number of original formats to run natively
on CPUs that have a working simple C compiler (maybe only K&R or C89) but
don't have an LLVM back end.

The source program could be in modern C, C++, or any other high level
language or assembly language with a translator to LLVM.
