** Description changed:
This is a follow-up to LP: #1769657. I'd like to update the toolchain
packages in bionic, to state which we have in disco in Junuary 2019:
- gcc-8, update to the gcc-8.3.0 release
- gcc-7, updates to the gcc-7.4.0 release
- corresponding gcc-cross packages
The package builds are prepared in
https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/ppa/+packages
[Impact]
Provide an upstream release for GCC 7, and update GCC 8 to the 8.3.0
release
[Regression Potential]
There is regression potential, however with a test rebuild of the complete
archive no regressions were found.
[Test Case]
No regressions in the GCC test suite, and no regressions in the test
rebuild of the main component of the archive (all architectures)
As a test, a complete archive rebuild was performed, and no regressions
were found with this new package. The archive rebuild also contained
updated versions of OpenJDK, OPenSSL, gcc-7, gcc-8, python3.6 and
python3.7. The OpenJDK, OpenSSL, GCC and Python packages should not
infer with each other.
[Validation]
Analyze the build logs for regressions.
For the cross builds, just make sure that the packages build using
the updated sources.
Summary of the test rebuilds:

http://people.canonical.com/~doko/ftbfs-report/test-rebuild-20181222-test-bionic.html
The first one is a reference build, the second one the test rebuild with
the updated components.
- No regressions attributed to GCC are shown with the test rebuild.
+ An analysis of the build failures was done in
+
https://docs.google.com/spreadsheets/d/1tMIwlwoHH_1h5sbvUbNac6-HIPKi3e0Xr8ebchIOU1A/edit#gid=147857652
(Sheet2).
+
+ No regressions attributed to GCC are shown with the test rebuild for
+ main, the universe component looks ok, except for packages relying on
+ specific GCC versions (ggcov: LP: #1817554), packages needing no-change
+ uploads (e.g. eclipse-titan).
