Here's the response I sent to Miguel:
While possible, it would be _very_ difficult. LLVM code is more
expressive/low-level than CIL code: for example array bounds checks are
not implicit, and there is no object model. I'm not sure exactly how you
would map general C programs onto the managed runtime at least, much less
general LLVM programs. The best way to do this would be to make a _new_
C/C++ compiler like Microsoft did, which adds language restrictions for
On the other hand, we've been talking about implementing a CIL front-end
for LLVM, which is possible because LLVM is lower-level than CIL. This
would also have the advantage that all of the IPO and other features of
LLVM could be directly applied to CIL code.
