Yes, I can act as a mentor.
I'm particularly interested in what we are going to do at -O0. Ideally,
I would try to build the SSA form and/or a predicated SSA form and try
to phrase the problem in terms of propagation of the uninitialized
attribute.
I agree with your goal of consistency. The erratic behaviour of the
current -Wuninitialized implementation is, to me, one of the most
annoying traits of GCC. We can't even reorder the pass pipeline without
running into this problem.
