Hi, Andrea:
Thanks for your quick response!
There is indeed a demand for this feature. You can find a discussion in Chinese on https://emacs-china.org/t/pdump-native-comp/15234.
I'd love to see this feature officially supported. Pdumper has been a feature of Emacs 27. After you merge native-comp branch into master branch in the future, I believe there will definitely be more and more people to try this combination.
Ying

Hi Ying Qu,
I guess you are the first trying to re-dump a native compiled Emacs
session. Despite being in principle possible there's certanly something
to look at.
In general my understanding is that ATM we do not support officially
Emacs re-dumps, so also on a vanilla build it may work or not.
As a consequence I'm not sure this is a requirement for this feature
ATM. Perhaps we'll get some other opinion on this.
Thanks
Andrea
