native comp and user init files

native comp and user init files

[Sean Whitton]

Hello,

Trying out nativecomp for the first time today.  I noticed that .eln
files corresponding to the variuos .el files I have under ~/.emacs.d,
both init.el and some others, are not appearing in
~/.emacs.d/eln-cache.  Shouldn't those files get async compiled too?  If
not, can I turn it on somehow?

Thanks!

Hi Sean,

only file byte compiled and loaded are automatically native compiled.

That said unless you are doing any computation with code in your .emacs
I guess you'll not be able to apretiate any speed-up.

Ciao!

There are quite a few function definitions in there, though I haven't
measured how computationally intensive they actually are.

One annoyance with arranging to have .el files in .emacs.d bytecompiled
is you need some mechanism to ensure they get recompiled when your Emacs
build changes, e.g. when you rebuild Emacs from git.

But cached .eln files are already tied to the build of Emacs which
generated them, right?  So if I were to call `native-compile' on each
.el file under ~/.emacs.d I wouldn't have to worry about removing the
compiled output when I rebuild Emacs, since a different Emacs build
would ignore the old .eln files?  Does that sound plausible?
