I would be curious to see the performance results of a system with the
properties you mentioned (optimization at super-block level,
compilation on a different core) and IMO using LLVM for such a system
would be a great choice.

We have looked more into LLVM docs. Indeed it looks feasible and
promissing.<br>
We are wondering about passes. The kaleidoscope tutorial refers to <br>
<pre> OurFPM.add(createInstructionCombiningPass());
// Reassociate expressions.
OurFPM.add(createReassociatePass());
// Eliminate Common SubExpressions.
OurFPM.add(createGVNPass());
// Simplify the control flow graph (deleting unreachable blocks, etc).
OurFPM.add(createCFGSimplificationPass());
</pre>
Where are these passes documented ? <br>

Our new system is too young. We do not have accepted papers yet ...<br>
