I, from scratch, built Emacs with native compilation and built and
installed using NATIVE_FULL_AOT=1. There is indeed a
/usr/local/lib/emacs/28.0.50/native-lisp dir with a directory that
contains the natively-compiled files. However, if I start emacs, even
with -Q, from a fresh user, files get compiled and put into the user
native compilation cache (~/.emacs.d/eln-cache/...). Has anyone else
noticed this? Or have I just made a mistake somewhere when testing
this?
If I use emacs -Q and do `C-h i', I get compilations for the following
files:
bytecomp-12882072-ffdd30ae.eln comp-cstr-ef162ef7-c492cd97.eln
byte-opt-9c5f25f5-b7c94b77.eln gv-e0cf7478-eac584a4.eln
cconv-3b1f1f98-ac4628a4.eln help-mode-d4dbae3d-034e8cf5.eln
cl-extra-d7051cba-ff815ded.eln info-ce12c0ca-3d2b00fd.eln

comp-7672a6ed-56d0b5ab.eln warnings-28e75f4d-c98d4e00.eln
I would have thought that it would use the ones in
/usr/local/lib/emacs/28.0.50/native-lisp instead of recompiling them?
If it can be confirmed that this is a bug, I'll submit a proper bug
report.

Hi Michael,
please open bug with M-x report-emacs-bug so we more details on your
build and we can handle the bug in the bug tracker.
Thanks

It could be because the abi-hash was modified due to changes elsewhere
in Emacs (e.g., addition of new primitives). Did Emacs create a new
subdirectory in ~/.emacs.d/eln-cache?

Yes, a bug report would be good.

1+, see the message I just sent in response to another thread with
Andrea.
What I also notice is that if I batch-byte-compile all of emacspeak
(with no other native-emacs running, then start native-emacs --
emacspeak modules still get recompiled at random times
