--- Comment #3 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
I filled in PR103423. Interesting observation is that both regressions are cca
18% but happens at different time-ranges.  This one is spec2017 WRF while the
other is spec2006 WRF and neither reproduce on both.

So perhaps modref improved enough in July to regress compile time of 2006 wrf
while for 2017 it needed couple more months...
