JIT through LLVM

[Muthiah Annamalai]

Hello,

I was thinking if we could use LLVM (parallel Virtual Machine, 
http://llvm.org)
IR-code and JIT engine as possible backend / target for Octave
code. This could start from the existing AST-walker and emit code.

LLVM is a C++ library, and from the looks of the tutorials very
powerful, as they implement the complicated optimizations like
dead-code elimination, eliminating common sub-expressions and
such.

So if we could manage to convert the Octave AST to LLVM IR, then
much of the problems of the lack-of-JIT would be solved; atleast in
principle.

However someone with time and expertise needs to look into this.

Im just posting this email, so if anyone is working on trying to
bring JIT support, can take a look at this, and also serve as a pointer. 

Best,
