Subject: 29.0.50; "Autoloaded" information lost in native compilation?
Date: Sun, 24 Jul 2022 19:10:03 +0300

To reproduce:

  emacs -Q
  C-h f rmail-movemail-variant-p RET

(or any other autoloaded function).  Assuming that the function's .el
file was already natively compiled to produce a .eln file, the
"autoloaded" part will not be shown in the *Help* buffer, Emacs will
only say that this is a native-compiled function.

Is it possible to resurrect this information from natively-compiled
Lisp code?  If not, what would have to be done to include this
information (and how does auto-loading works if the information is
lost in the first place)?

Yep will do, sorry it completely slipped under my radar.

On current master before requiring rmail on C-h f
rmail-movemail-variant-p RET I get:

===
rmail-movemail-variant-p is an autoloaded byte-compiled Lisp function
in ‘rmail.el’.

(rmail-movemail-variant-p &rest VARIANTS)
===

After requiring rmail (and having it native compiled) I get:

===
rmail-movemail-variant-p is an autoloaded native-compiled Lisp
function in ‘rmail.el’.

(rmail-movemail-variant-p &rest VARIANTS)

Inferred type: (function (&rest t) boolean)
===

So I guess the issue has already been fixed (or I'm not reproducing it
correctly)?

Best Regards

  Andrea

No, you are reproducing correctly.  It's also seems to be fixed on the
emacs-29 branch, so I will close the bug.  Sorry for not
double-checking before I pinged you.

No problem, a bug that's already solved is the best outcome we could
desire :)
