Doing call graph changes should not be that hard (I was trying to keep similar deisgn in mind when implementing it, even if we stepped away from the plan in some cases, like reorganizing passes from vertical to horisontal order). Nearest problem I see is merging different declarations of units read back, I have prototype implementation of DECL merging pass done from my trip this week and hope to have it working at least for --combine and C during christmas.
