[Bug 1769657] Re: update toolchain packages for bionic

[Matthias Klose]

** Description changed:

  I'd like to update the toolchain packages in bionic, to state which we
  have in cosmic on May 07:
  
   - LP: #1771635: binutils updates from the branch
   - gcc-8, update to the final 8.1.0 release
   - gcc-7, updates to the gcc-7-branch up to the time of the
     8.1.0 release.
   - gcc-defaults to bump the 8.1 version, and add some provides
   - build-essential to add cross packages for amd64 and i386
   - corresponding gcc-cross packages
  
  The package builds are prepared in
  https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/ppa/+packages
  
- There is regression potential, however with a test rebuild of the main
- portion of the archive no regressions were found.
+ [Impact]
+ Provide an upstream release for GCC 8, and update GCC 7 fixes to the
+ date of the corresponding GCC 8 updates.
+ 
+ [Regression Potential]
+ There is regression potential, however with a test rebuild of the main portion of the 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 (main only) was performed, and no
  regressions were found with this new package. The archive rebuild also
  contained updated versions of gcc-7, gcc-8, binutils, python3.6 and
  python3.7. The 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:

  No regressions are shown with the test rebuild.

  The package builds are prepared in

  [Impact]
  Provide an upstream release for GCC 8, and update GCC 7 fixes to the
  date of the corresponding GCC 8 updates.

  [Regression Potential]
  There is regression potential, however with a test rebuild of the main portion of the 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 (main only) was performed, and
  no regressions were found with this new package. The archive rebuild
  also contained updated versions of gcc-7, gcc-8, binutils, python3.6
  and python3.7. The 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:
  file:///home/ubuntu/ftbfs-report/production/test-rebuild-20180730-bionic.html
  http://people.canonical.com/~doko/ftbfs-report/test-rebuild-20180730-gcc-bionic.html

  No regressions are shown with the test rebuild.
