You could add this logic to the tree-tailcall.c pass. I suppose what you really want is no dominating call rather than only a single call in total.
Yes, that's true. I am currently porting the backend to 4.6.1 so I might do the changes in tree-tailcall on that version and leave the extra passes around expand in GCC 4.5.3 for now since our 4.5 is really just a bridge for our users to upgrade from our older 4.2/4.3 ports.
