Re: Implementing an Ada compiler and libraries.

I have one!  I'm porting the GNAT Ada f-e to LLVM
(http://llvm.org/), which replaces the gcc code
optimizers with those of LLVM.  LLVM has a C backend
which turns its IR into C.  So you can put Ada in and
get C out.  Unfortunately the C is not always compilable.
For example, if you compile an instance of GNAT.Table with
Natural as the index type, in the C you end up with the
declaration of a very big C array, corresponding to
Big_Table_Type.  This array is rejected by the gcc C
compiler as too big.  Still, it works most of the time.
