Here is what I think the two major improvements of this patch over the existing codegens:
- the use of the scalar references for the stmt being translated: these are actually the only scalars we care about for cross BB dependences, so they need renaming and phi nodes at CFG junctions,
- the use of the structure of the generated code to place the new phi nodes.
The more I think about this algorithm, the more I like it ;-)
