I think there's something wrong with the reported list of regressions.
If I run validate_failures.py manually from the precommit job's
artifacts.precommit directory I get a shorter list of regressions:
$ validate_failures.py --manifest=06-check_regression/baseline.xfail
--results=<(unxz -c sumfiles/gdb.sum.xz)
Manifest: 06-check_regression/baseline.xfail
Getting actual results from user-provided results

[ Snipped the rest of the output for brevity, but the list of potential
regressions above is complete. ]
Guinevere,
The FAILs in gdb.threads/ are almost surely regressions not yet marked
as such by our CI. I also see the gdb.base/gdb-sigterm.exp and
gdb.mi/mi-break.exp FAILs on current trunk so they're also false
positives.
OTOH gdb.reverse/solib-precsave.exp passes fully on trunk so it looks
like a real regression.
