I while back I saw a paper[1] from someone who integrated semantic diff for VCS. They said that it works well for toplevel changes to the file (movind classes around, etc), but it doesn't work as well for changes inside functions. For changes at the statement level, text diff worked better. [1] Unfortunately, I don't remember the name of the paper though :(
