File README.First-for.SuSE.packagers of Package Gcc9

IMPORTANT: Please change gcc.spec.in and then run ./pre_checkin.sh!
Do not change gcc.spec directly!

Since GCC comes with a testsuite that runs for quite a long time and
that test suite also contains some known failures, we should run the
testsuite of GCC whenever the compiler is changed to ensure a high
quality compiler.

The package is now split into multiple parts, gcc$VER,
gcc$VER-testresults and libffi$VER (plus various spec files for
cross and icecream cross compilers).  The testsuite is run from
gcc$VER-testresults, a dummy package with the testresults, gcc$VER-testresults,
is generated from it which contains testing logfiles and summary.

Before checking in a new compiler, please do the following steps as QA
measure to check that the new compiler does not introduce any new
failures:

- Run mbuild for all archs for at least the gcc$VER and the gcc$VER-testresults
  subpackages

- When mbuild is finished, call
  /suse/rguenther/bin/compare-testresults.sh mbuild-directory
  (for the gcc$VER-testresults build).
  The output of that script should not show any failures.  If it does,
  please fix them or discuss this with the gcc package maintainers.

- Do not remove this file.

Thanks,
Your GCC packagers.
