I tried it now--it *does* work on i686 if I follow the README of mrustc and build both it and rust 1.19 using the Makefile of mrustc. (I haven't tested armhf and x86_64 on mrustc master yet) But when I use our separate package definitions it fails when building libcore (which is the first library for the target compiler). Invoke seems to swallow the output, so I have no idea where or why it failed (grr). It's easily possible that some rust 1.19 build flags have to be adapted for the newer mrustc, but I don't know which yet. (Obviously, mrustc's makefile and/or Cargo.tomls already did the adaption if any)

Hmm. What makes you think that 'invoke' swallowed the output? You
might be right, but 'invoke' is used quite widely by now in Guix,
including to invoke 'make' in gnu-build-system, and I haven't seen
reports of it swallowing output.
I looked at the code. 'invoke' calls 'system*' which calls
'scm_open_process' (in libguile/posix.c) with an empty mode string.
In this case, the child STDOUT becomes (current-output-port) from the
parent if (current-output-port) is a "file port", i.e. a Guile port
backed by a POSIX file descriptor, e.g. a file, socket or pipe. If it's
a Guile port that's not backed by a file descriptor, e.g. a custom port,
soft port, string port, bytevector port, etc, then indeed the child
output will go to /dev/null instead.
(Note that the port returned by 'open-pipe*' when used in OPEN_BOTH mode
is also a soft port and not considered a file port, even though it is
internally backed by two file ports.)
Ditto for STDERR, except that it uses (current-error-port).
So, if 'invoke' seems to be swallowing output, it's probably because it
was called within the dynamic extent of 'with-output-to-port',
'with-error-to-port', 'with-output-to-string', or similar.
Regards,
Mark

Danny opened a bug report with the mrustc upstream:
https://github.com/thepowersgang/mrustc/issues/108
The last message there tells us to try again with current HEAD on
master. If this fails I think it’s acceptable to use a binary for the
very first Rust on i686; we would skip the use of mrustc on i686 then.
Not great.

Extra info: guix mrustc seems to be compiled with gcc 8 but guix rust-1.19 with gcc 5.5. How did that happen? Doesn't sound like a good idea since one loads compiler plugins compiled using the other into the same process.

I found out what was up with invoke. The child process didn't output anything on stdout or stderr, but it died with SIGFPE and I either was unable to interpret invoke's exception properly, or it didn't say (probably the former). It seems that mrustc uses a different gcc version than rust 1.19 which seems to be a bad idea to me, but not sure whether it's the cause of the SIGFPE.

The problem is NOT reproducible in Debian with the same gcc version. Maybe I'll get my home internet set up next month and put a Guix machine on it, but right now I only have mobile internet (with very slow upload and behind NAT). As it is now, I cannot reasonably give someone a Guix machine already setup to debug this problem. The problem is 100% reproducible and I estimate would be easy to fix for the authors--and maybe would fix the similar armhf problems as well. So if someone could put a Guix machine on the internet and give thepowersgang access, that would be great. I can't right now. If that happens, I can instruct thepowersgang how to enter an environment where this problem can be reproduced and fixed. Even at the last FOSDEM, Chris Marusich and I saw this problem and fixed part of it--by now we got upstream attention. (After all this inertia maybe we lost upstream attention again--we'll see) > Any ideas of a fix or workaround we could apply? No, but thepowersgang might find it very quickly. They guess it might be some C undefined behavior being used by the mrustc->C translator, or a problem with the struct layout (although I've checked the latter and it should be fine).

What about giving them “guix pack mrustc”, or a guix-install.sh + pull
command sequence, or a VM image?
The instructions would be:
1. Download and run <https://guix.gnu.org/install.sh>. It will
perform the steps described at
<https://guix.gnu.org/manual/en/html_node/Binary-Installation.html>.
2. Write this to a file:
(list (channel
(name 'guix)
(url "https://git.savannah.gnu.org/git/guix.git")
(commit
"0b2ea78173f05c417a9002e52e2b36b139074124")))
3. Run ‘guix pull -C that-file.scm -p ~/core-updates’.
4. Run ‘~/core-updates/bin/guix build rust -s i686-linux -K’.
Investigate as per
<https://guix.gnu.org/manual/en/html_node/Debugging-Build-Failures.html>.
Perhaps you could propose them to do that, and if that’s too much to
ask, we can meet halfway somehow.
Of course we can also provide guidance on #guix on IRC.
WDYT?

Would Valgrind or ASan be able to flag the potential issue?

[Message part 1 (text/plain, inline)]
Hi, On Fri, 18 Dec 2020 16:19:10 +0100 Mathieu Othacehe <othacehe@gnu.org> wrote: > The CI is spending a considerable amount of time trying to build Rust > packages for "i686-linux". As this is currently broken, what do you > think about applying the attached patch? Sure, for the time being. But seriously, mrustc supports a lot of other architectures (including defining custom architectures in config), and also can bootstrap Rust 1.29.0 directly. It's better to just update mrustc. (Marius Bakke already tried to integrate the mrustc update to core-updates--not sure what the roadblock was. Even if there was a roadblock, mrustc upstream was committed to 7 days ago--maybe the roadblock is gone now ?)
