Hello,
I wanted to give the "feature/native-comp" branch a try on an old 32-bit
laptop I have lying around[1]; unfortunately compilation ended abruptly
on the first couple of ELC+ELN steps (emacs-lisp/macroexp.elc and
emacs-lisp/cconv.elc). See [2] and [3] for fairly uninformative
backtraces; I installed libgccjit0-dbg between [2] and [3], hoping that
would make the backtrace more precise, but obviously this didn't work.
(I see that the second run started with lisp/abbrev.elc and
international/titdic-cnv.elc instead of emacs-lisp/macroexp.elc and
emacs-lisp/cconv.elc; is this expected because make(1) processes
dependencies in an arbitrary order, or is it possible that the first
aborted run left artifacts that lead make(1) to believe that the targets
are up-to-date? FWIW there is a new folder called
eln-i686-pc-linux-gnu-639e57b3ce60d5a9 under lisp/emacs-lisp, which
contains 0-byte files named cconvPDRUUG.eln and macroexpWFTb2Q.eln.)
Is my setup supposed to be supported? I haven't read everything related
to this new feature in detail, so maybe I missed a memo warning against
trying it out on i686. Otherwise, is there anything I can do to make
this easier to debug?
Thank you for your time.

Hi Kévin,
thanks for reporting.
please try compiling and running this:
https://gcc.gnu.org/onlinedocs/jit/intro/tutorial01.html
we'll know to begin with if this is an issue of the native-comp branch
or (as I suspect) of the libgccjit package of the distro.
Thanks

For the record, I've just pushed a commit that embeds a simple libgccjit
smoke test directly into the configure. So you should get the answer
also pulling regenerating and running the configure.

Good guess: that compiles without any warning, then segfaults too.
Should I follow the instructions from
https://gcc.gnu.org/wiki/JIT#Building_it_from_source to get a more
recent libgccjit.so? Is there a minimal required version, or does the
problem come from something else? (E.g. the way the distro compiled the
library.)
Feel free to close this report; I can open a new one if needed after I
get the tutorial you mentioned running correctly.
Thank you for taking a look at this.

All versions should work but at this point I'd go for releases/gcc-10 or
releases/gcc-9.3.0
Yes that's the link to look at.

Thanks, I went with 9.3.0. Now the "ELC+ELN" steps start smoothly,
unfortunately I don't think the little buster can finish the job :(
I first ran a -j2 build which crashed after 14 hours while compiling
char-fold.elc. I didn't get anything more precise than "virtual memory
exhausted: Cannot allocate memory" on the console.
Thinking it might help to compile only one file at a time, after
removing the temporary files related to char-fold.el[1], I started a -j1
build which picked up where the previous build left off, i.e. with
char-fold.elc.
Unfortunately that file alone seems to be too much for my system to
handle; compilation ended with the same "virtual memory exhausted" error
after less than an hour and a half.
I recorded some information related to memory usage during this second
run (cf. attached graph[2]). My takeway is that at some point, the
compilation process's memory usage skyrockets, until the system's memory
(2GB RAM + 2GB swap) is completely exhausted.
I haven't reopened/created a new issue because I'm not sure there's a
way forward; let me know if you'd like me to perform some more in-depth
profiling.
[1] lisp/char-fold.elc… and lisp/eln-i686-pc-linux-gnu-…/char-fold….eln.
[2] The graph shows:
- the VSZ of the process using the most virtual memory,
- the RSS of the process using the most virtual memory,
- the "available" column shown by free(1) on the "Mem:" line,
- the "used" column shown by free(1) on the "Swap:" line,
- the name of the process using the most virtual memory.
Measurements were taken every minute. I can upload the sources for
this graph (measurement script, measurements, and plotting script)
if that helps.

I must have replied privately to this so I'm quoting my previous mail.
That said I've just pushed a commit that exclude from native compilation
all the leim db files.
Overall compile time looks went down by a factor two!
Hope this helps. If you could get a measure of the memory consumption as
well that would be great.
Thanks

Hi Andrea!
Thank you for implementing this blacklist; it turns out that
char-fold.el was the only file my laptop could not handle[1], though as
you'll see org.el was a strong contender.
It took 3 days, but make -j1 successfully ran to completion on commit
92cf4bb. In comparison, I've just compiled commit 9d8fc3a on master
from scratch, and it took exactly 1 hour 35 minutes.
As soon as I've figured out how to use the elisp-benchmarks package,
I'll post some figures; is there a specific place (bug number,
emacs-devel thread) where you usually collect such feedback?
I've attached some more graphs on the compilation process, as well as
the source material[2] (measurement script, measurements, and plotting
script).
The overall picture (only files which took more than 10 minutes to
compile are labeled):

Some comments:
- As could be predicted from your previous measurements, org.el was a
beast, but unlike with char-fold.el the little guy pulled through 🙌
- It's hard to be sure since my measurements were so imprecise[3], but
AFAICT the compilation process for a single file seems to follow a
memory usage pattern of "slow rise - spike - drop - spike". See
e.g. files.el, isearch.el, simple.el, subr.el, window.el, info.el,
package.el, erc.el, gnus-sum.el, org.el, python.el.
Thank you for taking the time to guide me through compiling this branch.
I know that reducing the memory footprint of native compilation is
probably not your main focus right now, but I figured it would be
interesting to provide some orders of magnitude.

[3] I didn't instrument the build process; as can be seen in the
scripts, I just relied on:
ps --sort=-vsz p $pids | head 1
$pids include the emacs session in which I was running make; this
session was masking basically everything other than the ELC+ELN
processes.
Also, the sampling step being 30 seconds, a lot of interesting
patterns may not have been recorded.
Overall these scripts are an exercise in How Not To Collect Data 😒.

Wow thanks so much for the great report! I'm glad it worked for you.

Cool, we have no bug number for that. I guess you can use the "On elisp
running native" thread or as you feel.

It's very interesting thank you, your work will be usefull when we move
on the subject of compile-time/memory usage. I've some idea on the code
generations side and we'll need to measure how it translates on the
compilation process.
Thanks

Mmm, I've installed the elisp-benchmarks package, and I've run
$SOURCEDIR/src/emacs -Q -batch -l ./elisp-benchmarks.el -f elisp-benchmarks-run
from ~/.emacs.d/elpa/elisp-benchmarks-1.1, once with SOURCEDIR pointing
to the master worktree and once again with SOURCEDIR pointing to the
feature/native-comp worktree, and I get more or less the exact same
performance[1].
I've run the feature/native-comp emacs under strace and AFAICT the
native libraries get loaded[2]; I suspect I'm making some very basic
mistake but I can't put my finger on it. Is there anything else I
should be looking for to assert that things work as intended?
Thank you for your patience.

[2] I've attached traces for the first benchmark iteration; from what I
can tell .eln files are "loaded" correctly (I can see successful
calls to openat, read, fstat, mmap and mprotect).

I've run emacs master under strace too, out of paranoia; no .eln
file gets loaded there, as expected.

Hi Kévin,
No issue, I think you need to hack a little bit elisp-benchmarks because
by default the package manager just byte compile the files during
installation and elisp-benchmarks does not support officialy this
feature branch.
That would translate into somenthing like changing the call to
`byte-compile-file' into `native-compile' and running it with recompile
t.
Other option maybe quicker: you can manually native compile the
benchmarcks and the native emacs instance should load them.
You will see that when a .eln is loaded the message is a little
different to indicate that.
Probably what you have observed tracing was the activity of all the
other .elns I guess.
Best
Andrea

Ah, right; I don't know what I was thinking. I guess I assumed that the
benchmarks covered Emacs subroutines, so not compiling the benchmark
sources would not have a big impact. I got that completely backward 🤦

I went with this option, using M-: (native-compile "foo.el"). I had one
last surprise: the native-compiled fibn test exhausts the laptop's
memory (2GB RAM + 2GB swap). I recompiled fibn.eln setting comp-speed
to 1 and 0, but the result was the same.
Here are the results: except for pidigits, the improvements are quite
noticeable :) I'll post a write-up (giving my hardware specs and
computing the speedups) to emacs-devel when I find the time.

Hi Kévin,
If you could open a bug with that would be great so we can keep it under
the radar and handle it there.
