Backport GCC 5.4.0 and binutils 2.26.1 to 16.04 LTS

Status changed to 'Confirmed' because the bug affects multiple users.

The gdc front-end also saw an update from gdc's gcc-5-branch; verified that we don't see any regressions for packages build-depending on gdc.

For the armhf and arm64 architectures, the Linaro support was updated from the 5-2016.04 snapshot to the 5-2016.06 snapshot. This is the last Linaro snapshot in the 5 series seeing new backports (before switching to the 6 series). All backports were taken from GCC trunk, which was in stage3/stage4 at this time, only allowing regression fixes.

binutils's and GCC's testsuite don't show any regressions, compared to the versions included in the xenial release.

Hello Matthias, or anyone else affected,

Accepted binutils into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/binutils/2.26.1-1ubuntu1~16.04 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

comparing the base line rebuild with the toolchain rebuild (which includes -updates and -security), you see:

 - 2905 builds which fail in both test rebuilds

 - 91 progressions

 - 86 regressions (analysis below)

The -proposed update is quite a bit larger, presumably the backport forgot to disable the extra debugging stuff? E. g. xenial's cpp-5 is 7.7 MB, while xenial-proposed's is 30 MB.

Package: cpp-5
Version: 5.3.1-14ubuntu2

Marking v-failed for now, as I don't think we should put this big download overhead on everyone in a stable release, nor that it was intended.

now properly stripped.

On the kernel side, we have copied these updates to our bootstrap PPA and rebuild the current xenial-proposed kernel with them. The builds were successful on all architectures. We have also boot tested these kernels on amd64, ppc64el, and s390x.

wcsaxes is now fixed, see LP: #1598152.

gcc-5-cross-ports now migrated to the release pocket

both gcc-5-cross and gcc-5-cross-ports build and are installable.

I'm able to use these (and I can verify they fix the problems I was having), so +1 to promotion to -updates. Thanks!
