loaddefs.el under cedet/

loaddefs.el under cedet/

[Eli Zaretskii]

What target in lisp/Makefile.in is supposed to create/update the
loaddefs.el files under cedet/?  After removing them, they don't get
re-created, which I think is a bug.  But I don't see what target did
that during bootstrap, so I don't know what to fix.

What am I missing?

The secondary loaddefs files are updated as a side effect of updating
the primary loaddefs file.  If you remove lisp/loaddefs.el the other
loaddefs files are forced to be updated as well.

Thanks, that worked.

But I think we should add these 3 files to LOADDEFS, so that removing
them causes them to be re-created.  WDYT?

Btw, "make autoloads" leaves loaddefs.el~ in the subdirectories of
lisp/cedet.

That's not appropriate, as the comment above LOADDEFS indicates:

  # Note this includes only those files that need special rules to
  # build; ie it does not need to include things created via
  # generated-autoload-file (eg calc/calc-loaddefs.el).

Doing what you suggest would have no effect anyway. The `autoloads'
rule contains a `doit' dependency, which means it always runs. Simply
running the rule does not necessarily recreate the cedet loaddefs.

You cannot get the result you want without changing the way the Emacs
autoloads mechanism currently works. Your point seems to be, that if
you delete one of the cedet loaddefs files in isolation, and then run
`make autoloads', it will not be recreated. The last time this
question came up, the answer was "If it hurts, don't do that."
