- use mode_Iu for all nodes producing integer values (because registers are mode_Iu), this gives more possibilities for cse - use mode_D for all nodes producing float values, this gives more possibilities for cse - Introduce NoReg and Unknown nodes so we don't have strange projs from the start barrier - Rewrite transform phase: - while transforming we now build a completely new graph on a new irg (while looking at the old graph) - no need to transform constants in advance anymore - several smaller fixes+cleanups
