Hi, Andrea:

Thanks for your quick response!

There is indeed a demand for this feature. You can find a discussion in Chi= nese  on https://emacs-china.org/t/pdump-native-comp/15234.

I'd love to see this feature officially supported. Pdumper has been a featu= re of Emacs 27. After you merge native-comp branch into master branch in th= e future, I believe there will definitely be more and more people to try th= is 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 somethi= ng
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
