Subject: Endian problem with native compilation
Date: Fri, 27 Aug 2021 19:39:31 +0200

ppc and ppc64 all show the same failure.

All the cast functions are totally bogus.  They do not implement any
kind of type conversion.

Hi Andreas,

if you took the time to analyze the issue it would be very nice if you
could also mention which functions are you referring to.  This will
certainly help the volunteer that will fix them.

TIA

Andrea,

Regardless of whether the big-endian bugs are solved with this, could
you please try to give us an idea of how this change could affect the
native code produced by Emacs, and whether it could destabilize Emacs
with natively-compiled Lisp code to any significant degree?

We intend to start pretest of Emacs 28.1 soon, and I'm a bit bothered
by such low-level changes, because they could invalidate all the good
experience and debugging we accumulated since the native-comp branch
landed on master.  If this change is potentially destabilizing, we may
need to reassess our release schedule, so as to give this code more
time to mature.

Thanks.

This is changing the cast functions we synthesize and use in all the
code we generate, so yes it is potentially destabilizing.

That said the generated code looks correct to me (and considerably
cleaner).  Also, given these functions are really the foundation of a
lot of other code we generate I guess would be unlikely to have these
wrong but still have the testsuite passing clean and Emacs booting up
correctly.  Call me optimistic but I'd be pretty confident with this
change...

Not sure I can say more than this, hope it helps.

Regards

  Andrea

OK, thanks.  We'll see how it goes (after you find the problem with
endianness and fix it).

I've noticed that building Emacs --with-native-compilation after this
change still uses the same subdirectory of native-lisp/ for the
preloaded files, and doesn't recompile *.eln files that were
native-compiled before the change (unless the corresponding *.el files
were updated in the meantime).  Shouldn't we recompile all the *.eln
files after this change?

I don't know if Andreas did recompile all of them, but if not, perhaps
that's one reason why the change didn't fix Emacs on big-endian
systems?

Sorry, I'm not sure I understand: are you saying that change did fix
the problem?  I thought you previously said it didn't?

There is more to big-endian than s390x.

So s390x still fails, but the other 2 big-endian hosts succeed after
that change?

And that is after recompiling all the preloaded *.eln files?

There is nothing recompiled, always from scratch.

Ok, thanks.  So, partially good news, but some of the problem still
remains.

Hi Andreas,

would be interesting to know if the problem persists after the recent UB
fix in libgccjit.

Thanks

I'm glad you are sure about it.  Could you share with us what let you

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I didn't read this thread, but that URL seems to indicate that all the
builds are successful now, so should this bug report be closed?

More information was requested, but no response was given within a
month, so I'm closing this bug report.  If the problem still exists,
please respond to this email and we'll reopen the bug report.
