I've noticed that the native-comp branch preloads pcase:
Loading files (native compiled elisp)...
Loading emacs-lisp/macroexp (native compiled elisp)...
Loading emacs-lisp/pcase...
Loading emacs-lisp/macroexp (native compiled elisp)...
whereas on master this doesn't happen. Why is that? Do we really
need to preload pcase? If that's unavoidable, it should be added to
shortlisp, so that we eln-compile it.

Mmhh, I think is because of this from loadup.el:
====
(load "emacs-lisp/macroexp")
(if (byte-code-function-p (symbol-function 'macroexpand-all))
nil
;; Since loaddefs is not yet loaded, macroexp's uses of pcase will simply
;; fail until pcase is explicitly loaded. This also means that we have to
;; disable eager macro-expansion while loading pcase.
(let ((macroexp--pending-eager-loads '(skip))) (load "emacs-lisp/pcase"))
;; Re-load macroexp so as to eagerly macro-expand its uses of pcase.
(let ((max-lisp-eval-depth (* 2 max-lisp-eval-depth)))
(load "emacs-lisp/macroexp")))
====
> need to preload pcase?
I fear I don't have an answer as ATM I don't uderstand why it should be
different compared to master.

Stefan, any ideas why this happens on the native-comp branch but not
on master?

It's probably the `byte-code-function-p` which tries to distinguish the
case where macroexp has not yet been compiled, but on the native branch,
I suspect that (byte-code-function-p (symbol-function 'macroexpand-all))
will return nil when macroexp has been compiled because it's now
a `subrp`.
So we could replace
(byte-code-function-p (symbol-function 'macroexpand-all))
with
(or (byte-code-function-p (symbol-function 'macroexpand-all))
(subrp (symbol-function 'macroexpand-all)))
or with
(not (consp (symbol-function 'macroexpand-all)))

Ops should have spotted that :/ thanks for the suggestion.
711b2c8349 fix this for me.
Eli let me know if we are okay to close.
Thanks
