[Bug 1930125] [NEW] SRU: update gcc-9 and gcc-10 packages for focal, groovy and hirsute

Sat May 29 07:38:23 UTC 2021

Public bug reported:

as done before in LP: #1879481 with GCC 9.3.0 and GCC 10.2.0, updating
again to GCC 9.4.0 and GCC 10.3.0 in 20.04 LTS, 20.10 and 21.04.  GCC
10.3.0 is already in 21.04 (hirsute), so no need to update that compiler
there as well.

 - gcc-10, update to the gcc-10.3.0 release
 - gcc-9, update to the gcc-9.4.0 release
 - corresponding gcc-cross packages

The package builds are prepared in
https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/ppa/+packages
built with only the security pocket enabled.

[Impact]
Provide an upstream release for GCC 10.3, and an upstream release for GCC 9.4.
gcc-9 is the default compiler for focal, gcc-10 the default compiler for groovy.

[Regression Potential]
There is regression potential, however with a test rebuild of the main portion of the archive for both focal and groovy, we make sure that we don't see any regressions in package builds.

[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).  No test rebuild is done for hirsute, as gcc-9 is not the default compiler anymore.

Also check that the rebuilt kernel boots on all architectures.

TODO: 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 gcc-9, gcc-10, python3.8, and python3
-stdlib-extensions. The GCC and Python packages should not infer with
each other.

[Validation]
Analyze the GCC build logs for regressions.
For the cross builds, just make sure that the packages build using
the updated sources.

TODO: Summary of the test rebuilds:
https://people.canonical.com/~doko/ftbfs-report/test-rebuild-20200810-focal-focal.html
https://people.canonical.com/~doko/ftbfs-report/test-rebuild-20200810-focal-gcc-focal.html

The first one is a reference build, the second one the test rebuild with
the updated components.

There are no additional regressions except for pyxdg, which is unrelated
to the GCC update, and which was fixed by a separate SRU. Note that the
riscv64 builds are purely informational, and are not checked for any
regressions.
