Fedora mass rebuild 2016

[Marek Polacek]

In the past few days and weeks we did a mass rebuild of Fedora rawhide packages
in mock with GCC 6 (and corresponding libtool) and for those packages that
failed also rebuilt the same package with gcc-5.3.1-2.fc23.x86_64 to quickly
remove from the list packages that fail for non-GCC related reasons.

There were 17741 packages overall (last year we had 16230 packages).  16281
packages built fine, 883 packages failed to build with both gcc-6 and gcc-5
(ignored for this analysis, unlikely to be GCC 6 related).  This left us with
577 packages that had to be analyzed.  That is a lot -- last year we only had
to examine 236 packages.  So that's why it's taken so long.  

As usually, there will be a "porting to" document to ease the transition to
the new GCC.  We already have https://gcc.gnu.org/gcc-6/porting_to.html, even
though this document is still somewhat in flux.

The biggest change hands-down this year is the change of the default standard
for g++ from -std=gnu++98 to -std=gnu++14; this has caused considerable churn,
as you might have noticed on this mailing list.  Unfortunately, many packages
weren't prepared to handle C++11.  Changes in libstdc++ often revealed very
poor programming practices.

Before I describe the results in more detail, I'd like to thank Jon Wakely and
Jakub Jelinek for their indispensable help.

Any mistakes, omissions, or mis-categorizations are solely mine.

The following is a list of bugs we've found so far in the compiler and the
C++ library during the mass rebuild:

	these contained invalid code but are already fixed

Now, this is a list of packages that very likely contain invalid C++14 code.
Some of them worked in the past, but only by luck and were just ill-fated.
Please try to fix the issues rather than adding workaround flags like
-fpermissive, -Wno-unused-but-set-variable etc.

Most of the issues should be described in porting_to, so I won't repeat it
here.  Especially, if something fails, try using -fno-delete-null-pointer-checks
or -fno-lifetime-dse before opening a PR.  However, it's certainly possible
that a compiler bug might crept it, and the code is valid.  It's not feasible
for me to try to fix all these packages.

[Richard Shaw]

I've pretty much addressed all my packages except for cqrlog which I guess
wasn't on the list since it will compile with gcc 5. Upstream has stated
they will address gcc 6 issues on the next release.

My other two packages that I could find in your list, smesh & OCE, have
both been addressed and built. Unfortunately with smesh the solution was to
re-enable gnu++98. Upstream was surprised to find out it even built with
gcc 5.

Thanks,
Richard

At least this one has already been fixed upstream:

The discussion is in this bug:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=28901
But it could really use some concrete examples instead of handwaving
about hypotheticals. There is also a slight tweak to what is/isn't
considered "unused" patch under review here:
https://gcc.gnu.org/ml/gcc-patches/2016-02/msg01433.html
If people could test that out to see if that makes them happy/sad that
would also be appreciated.

Cheers,

Mark

This one was left-shifting a negative integer and also triggered
narrowing-conversion errors.

Fixed in Rawhide already.

I don't think this has been fixed.  I updated ntl over the weekend,
and rebuilt Macaulay2 as part of that work.  Macaulay2 still failed
with this same error, using gcc-6.0.0-0.11.fc24, so I added a patch to
workaround the issue, so as not to leave Macaulay2 with broken deps in
Rawhide.  Indeed, the gcc-6.0.0-0.11.fc24 changelog says:

- temporarily revert PR c++/10200 fix

The fix must have caused other issues, I guess.  I don't see anything
about that PR in the gcc-6.0.0-0.12.fc24 changelog, so I believe this
issue is still outstanding.

I already added -std=gnu++98 to this package, but the build still
fails.  I don't understand the gcc error.  GCC appears to be producing
non-const temporaries, and then complaining that the temporaries are
non-const.  I asked for help with this about a week ago, and Jonathan
Wakely said he would take a look.  I have not heard back from him yet:

https://lists.fedoraproject.org/archives/list/[e-mail].o...

Any ideas on what is going on there would be much appreciated.

The maddening thing is that upstream polymake has released a new
version, and the release notes say this new version brings "full C++11
compatibility".  But I can't update to it, because it needs Singular
4.x and normaliz 3.x, and updating those 2 packages will break both
Macaulay2 and sagemath.  Sigh.

-0.12.fc24 has the reversion removed, is in sync with what latest gcc does.
So, if you have some issue with -0.12.fc24 and you are convinced it is a g++
bug rather than package bug, please file it with small self-contained
reproducer.

I did look, but wasn't able to figure out the problem. My attempts to
reduce it to a small example didn't produce the same failure. I'll
come back to it ASAP and spend more time on it.

I'm still seeing build failures in 3Depict with gcc 6.0.0-0.12.fc24 that 
seem quite similar (though not exactly the same) to the original PR:

That's a different issue:

I'm fixing it in GCC today.

I see an inconsistency between s390(x) and other arches with "stdarg"
handling, build on s390(x) of a C++ lib fails with

error: first argument to ‘va_arg’ not of type ‘va_list’

Please see https://bugzilla.redhat.com/show_bug.cgi?id=1314545 for more
details and a reproducer.
