llvm dev - Jun 2016 - [cfe-dev] [Release-testers] 3.8.1-rc1 has been tagged

Hi,

I had a quick look at that link and it seems to be a linker internal error.
Presumably we're triggering a bug in the system toolchain.

FWIW, my mipsel build on a Debian Jessie machine (binutils 2.24.90.20141023-1)
successfully completed test-release.sh. I'm currently running the tests.

Here's the relevant bit of the log from your link:

Green on most of the Debian main archs:
https://buildd.debian.org/status/package.php?p=llvm-toolchain-3.8&suite=experimental
The armel & mipsel build issue are not regressions from 3.8 (but are
from 3.7)

Cheers,

Uploaded Fedora and openSUSE binaries. Test suite is green but I'm seeing
two libc++ test failures when running check-all. I'm pretty sure these were
present in 3.8.0, am I supposed to file bug reports for them?

If they're not regressions, do nothing.

You may want to open bugs for them, but I'm guessing there are already
some. None of them are blockers to the release, though.

What tests are failing?

Hi Sylvestre,

I tried to reproduce the mipsel build failure in a Debian chroot on my CI20 and
my build gets further than buildd.debian.org did.  I tried to match the config
and process described in the logs in the hope that I'd end up with the
roughly same environment but I ended up with some differences. The toolchain
package differences were:
	Binutils: 2.26-11 (the log had 2.26-10)
	g++: 5.3.1-3 (the log had 5.5.4.0-3)
	gcc: 5.3.1-3 (the log had 5.5.4.0-3)
	libstdc++-5-dev: 5.4.0-4 (the log had 5.4.0-3)
	libstdc++6: 6.1.1-6 (the log had 6.1.1-5)
	linux-libc-dev: 4.6.1-1 (the log had 4.5.5-1)
One process difference is that instead of running dpkg-buildpackage, I ran the
underlying commands. I stopped after a successful 'debian/rules build'
command since the last command it printed was the one that failed in the buildd
log.

If you can narrow the problem down a bit then I can investigate further. Also,
if you need help narrowing it down then I may be able to put you in contact with
a colleague who works on Debian.

Hi Daniel,

Is there a bug for this? One of the things we talked about earlier on
the release threads is that we should try to record every problem, so
that we can use that info later.

And though I have no idea how we could use the info later, recording
in bugzilla seems only sensible. :)

cheers,
