I'd appreciate pointer to the literature on "sinking pass". That being said, it's pretty clear to me that this pass generalizes far beyond "auto-init". There's an advantage in auto-init though: we can work under the assumption of "no aliasing" which helps a lot. I'm interested in making that pass more generic, probably as a second step though.
