I definitely consider Jan's changes major development -- he's basically
trying to replace jump.c with a CFG equivalent and keep the CFG consistent
throughout compilation.
The changes are quite extensive and have been consistently breaking the
tree across a number of architectures.
While Jan tried to do this work incrementally it hasn't been that successful
IMHO.

ps. Note that I do applaud Jan's goal and effort. Replacing jump.c with
its CFG equivalent and keeping the CFG up-to-date has been on my todo list
for a while now.
