Aliasing rules difference between GCC and Clang
...and this would give a NoAlias above, right? Did I understand this
correctly, or did I miss anything relevant?
What method(s) would need to be modified to handle this? Is it feasible
to do this now, or are there other planned steps that somebody is
working on?
Would this improvement require the NewStructPathTBAA flag to be on, and
if so, what is the outlook on this?
@Ivan: For what I can see, you had a list of planned improvements. What
are your thoughts on this?
Thanks for any help,

not want it to get in your way with the new TBAA.
