This is wonderful, Duncan.  I agree that this is a huge deal for Ada.
I only learned about LLVM a few months ago.  When I did, I filed and
Ada LLVM compiler in my drawer of Utopian ideas.  Thanks for making it
true!

I assume that due to the link-time optimization capability that
inlining among packages will be handled naturally.  GNAT-gcc can't do
that, right?  This alone ought to be a big deal as accessor/setter
conventions are leading to programs filled with tiny procedures and
functions.
