Thank you, Vladimir and Yang, for the feedback.
I just want to reiterate my plan of work on this in order to improve clarity. We're looking into a solution for allocation merges at the moment; we'll probably be looking into bringing some form of flow-sensitive EA later on after we get some progress with allocation merges. We don't have plans to implement Stadler/GRAAL EA algorithm in C2 at the moment.
Thanks,
Cesar
PS: Sorry for the delay... I'm in the middle of a leave.

which current EA does not provide.
