Hi all,

oops, sorry, I thought OpenC++ originates from Japan team, but name 
Grzegorz sounds like Polish for me :)

Do you mean that we should not discuss why JITing is 
important for Computational Reflection and OpenC++ in 
particular? It would be quite logical first to get sure 
that OpenC++ team is motivated to reach this goal
and only then discuss how to do it. I expected to have
this discussion in openc++ maillist.


Anyway, there are two general ways how to do it.

1. via C++:

   the OpenC++ sources are translated into C++ 
   (in run-time too) and then the C++ front-end 
   compiler from LLVM team is involved to 
   compile C++ code into LLVM assembler or a byte code.


2. via LLVM assembler or byte-code:

   the OpenC++ sources are translated into LLVM
   assembler. This work is expected to be quite 
   similar to the job done by Chris team over gcc.

maybe there are other smart ways how to connect 
Environment, Ptree and other OpenC++ entities to
LLVM, but at least two ways above seem to be 
technically feasible.

any comments?

P.S. sorry if you receive draft of this mail as well.
     It was much more in details though :)
