Two more HLVM benchmark results and questions about Windows and .NET

To illustrate the value of value types to the OCaml community I recently did
a couple of benchmarks. The first was similar to a hash table and stores
key-value pairs unboxed in an array:

The second is the hailstone benchmark that the Haskell guys found gave huge
performance improvements when using LLVM from GHC:

Surprisingly, the hailstone benchmark shows HLVM not only generating code
32× faster than OCaml but even beating GCC -O3 by a significant margin!

Now that we've basically converted from Linux+OCaml to Windows+F#, I'm
wondering how much interest there would be in using LLVM from F#. How many
people are using LLVM under Windows? How well does it work? Are there
existing .NET bindings that would make my life a dream come true?

I don't know of any existing .NET bindings. I suspect that most
people working in .NET would use the built-in System.Reflection.Emit
and System.Linq.Expression classes to generate code at runtime,
especially since .NET 4.0 has LINQ expression support for building
entire methods rather than single expressions. While LLVM might be
able to generate better code in some circumstances, there would be
managed/unmanaged overhead associated with calling the code and having
the code call anything in .NET.
